     DETAILED DESCRIPTION 
     The technical solutions in embodiments of the present disclosure will be described clearly and completely in combination with the accompanying drawings in some embodiments of the present disclosure. Obviously, the described embodiments are merely some but not all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on some embodiments of the present disclosure shall be included in the protection scope of the present disclosure. 
     In some embodiments of the present disclosure, “a plurality of” means two or more unless otherwise specified. “First” and “second” are used to distinguish between same or similar items whose functions and effects are substantially the same. Moreover, a person skilled in the art will understand that the “first” and “second” are not intended to limit a quantity and an order of execution of the items, and do not limit the items to be different from each other. 
     A continuous video image is formed on a display panel in a display apparatus in a plurality of frame periods (a frame period being the time for displaying one frame of an image) by displaying images frame by frame. In the related art, in each frame period, a line scanning circuit is generally used to perform a progressive scanning to all the sub-pixels in a whole display panel, so as to display one frame of an image. Based on this, all the sub-pixels in the whole display panel display the image at a same frame rate, generally 60 Hz to 240 Hz. 
     For common flat panel displays such as a TV display and a computer screen display, if a frame rate of a display image on the display apparatus reaches about 60 Hz, human eyes may view a very smooth display image. In a case where the frame rate is higher than 60 Hz, it is not easy for the human eyes to notice a significant smoothness improvement of the image. For an augmented reality (AR) display and a virtual reality (VR) display, a frame rate of the display image is required to reach 90 Hz to realize a smooth display. In a case where the frame rate reaches a few hundred hertz, the AR display and VR display will achieve an ideal effect. For a stereoscopic display such as a rotating display, a display of a stereoscopic image needs to quickly display several pictures in sequence to form a stereoscopic image. Therefore, the image displayed on the display apparatus need to have a particularly high frame rate (such as several thousand hertz or tens of thousands of hertz), so as to display the desired image smoothly. 
     Referring to  FIG. 1 , some embodiments of the present disclosure provide a display apparatus  1000  including a display panel  100  and a gate driving circuit  20 . 
     The display panel  100  has a display area  110  and a non-display area  120 . In the embodiments of the present disclosure, the display area  110  is an area for display in the display panel  100 , and the non-display area  120  is an area in a periphery of the display area  110  and not used for display. The display area  110  of the display panel  100  includes at least two sub-display areas  10  (for example, the display area  110  of the display panel  100  includes a×b sub-display areas  10  in  FIG. 1 ), and each sub-display area  10  of the at least two sub-display areas  10  includes a plurality of sub-pixels  11 . 
     The gate driving circuit  20  includes at least two gate driving sub-circuits  21  (for example, a×b gate driving sub-circuits  21  shown in  FIG. 1 ) in one-to-one correspondence with the at least two sub-display areas  10 . Each gate driving sub-circuit  21  of the at least two gate driving sub-circuits  21  is electrically connected to a plurality of sub-pixels  11  included in a corresponding sub-display area  10 . Each gate driving sub-circuit  21  is configured to receive a group of first control signals, generate a group of gate driving signals, and output the group of gate driving signals to the plurality of sub-pixels  11  included in the corresponding sub-display area  10 . 
     Based on this, it is possible that a number of sub-pixels  11  in different sub-display areas  10  in the display panel  100  is the same or different. For example, referring to  FIG. 2 , in the at least two sub-display areas  10 , a number of the plurality of sub-pixels  11  included in each sub-display area  10  is the same: or, referring to  FIGS. 3 and 4 , in the at least two sub-display areas  10 , the number of the plurality of sub-pixels  11  included in each sub-display area  10  is different. 
     Optionally, in a case where the number of the plurality of sub-pixels  11  included in each sub-display area  10  is the same, referring to  FIG. 2 , the plurality of sub-pixels  11  included in each sub-display area  10  are arranged in a matrix, and the plurality of sub-pixels  11  included in each sub-display area  10  are arranged in a same number of rows and in a same number of columns. 
     There may be various arrangement manners of the sub-display areas  10  in the display panel  100 . For example, referring to  FIGS. 2 and 3 , plurality of sub-display areas  10  in the display panel  100  are arranged in a matrix; or, referring to  FIG. 4 , the plurality of sub-display areas  10  are divided into any shapes according to display needs. 
     Some embodiments of the present disclosure do not limit an arrangement manner of the sub-display areas  10 , the number of the sub-pixels  11  in each sub-display area  10 , and a shape of each sub-display area  10 . In practice, the sub-display areas  10  may be divided according to actual display needs. 
     In some embodiments of the present disclosure, the display area  110  of the display panel  100  is divide into the at least two sub-display areas  10 . For each sub-display area  10 , the sub-display area  10  is driven by one gate driving sub-circuit  21 , so that an independent gate driving signal is input to the sub-display area  10  to realize a partition driving of the display panel  100 , and the sub-pixels  11  in different sub-display areas  10  may be synchronously scanned in one frame period. That is to say, each gate driving sub-circuit  21  only needs to scan the plurality of sub-pixels  11  in the corresponding sub-display area  10  without scanning all the sub-pixels  11  in the whole display panel  100 . Therefore, it takes a short time for each gate drive sub-circuit  21  to complete the scanning of the plurality of sub-pixels  11  in the corresponding sub-display area  10 . In a case where a plurality of gate driving sub-circuits  21  simultaneously scan a plurality of sub-pixels  11  in the corresponding sub-display areas  10 , the time for completing one scanning for all the sub-pixels  11  in the whole display panel  100  may be greatly reduced. That is, the frame period is greatly shortened, so that the frame rate of the display image is significantly increased, and the frame rate of the display image may reach an ultra-high frame rate. As a result, the display image has a higher clarity and smoothness, and phenomena of trailing, image retention or the like will not occur. 
     Herein, the ultra-high frame rate refers to a frame rate greater than or equal to 90 Hz, such as 90 Hz, 120 Hz, 240 Hz, 300 Hz, 500 Hz, 1000 Hz, 3000 Hz, 5000 Hz, 8000 Hz, 10000 Hz, or 20000 Hz. 
     In addition, some embodiments of the present disclosure may realize an independent driving of each sub-display area  10 . That is, parameters such as timing of one group of gate driving signals corresponding to each sub-display area  10  are adjusted, so that different sub-display areas  10  may display images at different frame rates, and an asynchronous scanning refresh between different sub-display areas  10  may also be realized. For example, a display image may be divided into a main viewing area image and a secondary viewing area image according to viewing needs and attentions to the display image of users. Sub-display areas  10  displaying the main viewing area image is considered to be in a main viewing area, and sub-display areas  10  displaying the secondary viewing area image is considered to be in a secondary viewing area. Each sub-display area  10  is driven separately, which may cause the sub-display areas  10  in the main viewing area to display an image at a high frame rate, and cause the sub-display areas  10  in the secondary viewing area to display an image at a low frame rate. Compared with a manner in which all the sub-display areas  10  in the whole display panel  100  display the image at a high frame rate, a data amount of source signals may be effectively reduced, thereby effectively reducing an overall bandwidth of data transmission without affecting viewing experience of the users. 
     Referring to  FIG. 1 , in some embodiments, the display panel  100  further includes at least two groups of gate lines  60  in one-to-one correspondence with the at least two sub-display areas  10 . Each group of gate lines  60  of the at least two groups of gate lines  60  is electrically connected to a plurality of sub-pixels  11  included in a corresponding sub-display area  10 , and each gate driving sub-circuit  21  is electrically connected to one group of gate lines  60  corresponding to the corresponding sub-display area  10 . A sub-display area  10  numbered a in  FIG. 1  is taken as an example. One group of gate lines  60  corresponding to the sub-display area a is shown in  FIG. 1 , and a gate driving sub-circuit corresponding to the sub-display area a is a gate driving sub-circuit a. The gate driving sub-circuit a is connected to sub-pixels  11  in the sub-display area a through the group of gate lines  60 . 
     There may be various arrangement manners of the gate driving circuit  20  in the display apparatus  1000 . For example, the gate driving circuit  20  may be provided separately, for example, the gate driving circuit  20  is a gate driving chip (Gate IC) or a gate driver on array (GOA) circuit. For example, the gate driving circuit  20  may also be integrated in a driving chip of the display apparatus. As long as it is possible to input the independent gate driving signal to each sub-display area  10  through each gate driving sub-circuit  21  in the gate driving circuit  20  to realize a partition control of each sub-display area  10 . Some embodiments of the present disclosure do not limit thereto. 
     Referring to  FIG. 5 , in some embodiments, the display apparatus  1000  includes a driving chip  50 . The driving chip  50  includes the gate driving circuit  20 . It will be understood that the gate driving circuit  20  is integrated in the driving chip  50  of the display apparatus. The driving chip  50  further includes at least two driving ports  51 , and the at least two driving ports  51  are electrically connected to the at least two gate driving sub-circuits  21  in a one-to-one correspondence manner. Each gate driving sub-circuit  21  is electrically connected to the group of gate lines  60  corresponding to the corresponding sub-display area  10  through a corresponding driving port  51 . 
     For example, referring to the display apparatus  1000  shown in  FIG. 5 , the display apparatus  1000  is provided with the driving chip  50  therein, and the gate driving circuit  20  is integrated in the driving chip  50 . The driving chip  50  further includes a×b driving ports  51  numbered from 1 to a×b. The display area  110  of the display panel  100  includes a×b sub-display areas  10  numbered from 1 to a×b, and the a×b driving ports  51  are in one-to-one correspondence with the a×b sub-display areas  10 . The sub-display area a is taken as an example, the gate driving sub-circuit a, a driving port a and one group of gate lines  60  that are corresponding to the sub-display area a are shown in  FIG. 5 . The group of gate lines  60  is connected to the driving port a. One group of gate driving signals output by the gate driving sub-circuit a is transmitted to sub-pixels  11  in the sub-display area a by the group of gate lines  60  through the driving port a. 
     In some other embodiments, the gate driving circuit  20  is disposed in the non-display area  120  of the display panel  100 . Each gate driving sub-circuit  21  is directly electrically connected to the group of gate lines  60  corresponding to the corresponding sub-display area  10 . 
     For example, referring to  FIG. 1 , the display panel  100  includes an array substrate. The gate driving circuit  20  is disposed on the array substrate in the display panel  100  and disposed in an area of the array substrate corresponding to the non-display area  120 . Herein, each gate driving sub-circuit  21  in the gate driving circuit  20  is, for example, a GOA sub-circuit. That is, one or more shift register circuits are integrated on the array substrate to form one gate driving sub-circuit  21 , and the plurality of gate driving sub-circuits  21  form the gate driving circuit  20 . The GOA sub-circuit serving as the gate drive sub-circuit  21  has the advantages of low cost, and is conductive to realize a narrow bezel of the display apparatus  1000 . In this case, signals received by each gate driving sub-circuit  21  are, for example, a group of first control signals including clock signals (CLK). A gate driving sub-circuit numbered as a is taken as an example. The gate driving sub-circuit a outputs one group of gate driving signals under the control of one group of first control signals, and transmits the group of gate driving signals to the sub-pixel  11  in the corresponding sub-display area through one group of gate lines  60  connected to the gate driving sub-circuit a. 
     It is worth mentioning that the gate driving circuit  20  may be disposed on at least one side of the periphery of the display area  110 , which is not limited in some embodiments of the present disclosure. For example, as shown in  FIG. 1 , the gate driving circuit  20  is disposed in the non-display area  120 , and is located on one side of the periphery of the display area  110 , so as to realize an unilateral driving for the sub-pixels  11  in the display area  110 . For another example, the gate driving circuit  20  is disposed in the non-display area  120 , and is located on two opposite sides of the periphery of the display area  110 , so as to realize a bilateral driving for the sub-pixels  11  in the display area  110 . For yet another example, the gate driving circuit  20  is disposed in the non-display area  120 , and is located on the periphery of the display area  110 , so as to realize a multilateral driving for the sub-pixels  11  in the display area  110 . 
     Referring to  FIG. 6 , in some embodiments, the display apparatus  1000  further includes a source driving circuit  30 . The source driving circuit  30  is configured to receive at least two groups of second control signals and at least two groups of first data signals, convert the at least two groups of first data signals into at least two groups of second data signals in one-to-one correspondence with the at least two sub-display areas  10  according to the at least two groups of second control signals, and output each group of second data signals to a plurality of sub-pixels  11  included in a corresponding sub-display area  10 .

For example, the source driving circuit  30  is a source driving chip (Source IC); or, the source driving circuit  30  may be integrated in the driving chip of the display apparatus. There may be various arrangement manners of the source driving circuit  30 , which is not limited in some embodiments of the present disclosure. 
     In some embodiments, the display panel  100  further includes at least two groups of data lines  70  in one-to-one correspondence with the at least two sub-display areas  10 .

The source driving circuit  30  is electrically connected to the at least two groups of data lines  70 . 
     For example, referring to the display apparatus  1000  shown in  FIG. 6 . The display apparatus  1000  is provided with the source driving circuit  30  therein.

The group of data lines  70  is connected to the source driving circuit  30 , and one group of second data lines output by the source driving circuit  30  is transmitted to sub-pixels  11  in the sub-display area a through the group of data lines  70 . 
     Referring to  FIG. 7 , in some embodiments, in a case where the display apparatus  1000  includes the driving chip  50 , the driving chip  50  includes the source driving circuit  30 .

The driving chip  50  further includes at least two data ports  52 , and the source driving circuit  30  is electrically connected to the at least two groups of data lines  70  through the at least two data ports  52 . 
     For example, referring to the display apparatus  1000  shown in  FIG. 7 , the display apparatus  1000  includes the driving chip  50 . Both the gate driving circuit  20  and the source driving circuit  30  are integrated in the driving chip  50 . The display panel  100  includes four sub-display areas  10 , i.e., a sub-display area c, a sub-display area d, a sub-display area e, and a sub-display area f. The driving chip  50  further includes a driving port  51   c,  a driving port  51   d,  a driving port  51   e,  and a driving port  51   f  that are in one-to-one correspondence with the four sub-display areas  10 , and a data port  52   c,  a data port  52   d,  a data port  52   e  and a data port  52   f  that are in one-to-one correspondence with the four sub-display areas  10 . The source driving circuit  30  is electrically connected to one group of data lines  70   c  through the data port  52   c,  and the group of data lines  70   c  is electrically connected to sub-pixels  11  in the sub-display area c. A gate driving sub-circuit  21   c  is electrically connected to one group of gate lines  60   c  through the driving port  51   c,  and the group of gate lines  60   c  is electrically connected to the sub-pixels  11  in the sub-display area c. Similarly, the source driving circuit  30  is electrically connected to one group of data lines  70   d  through the data port  52   d,  and the group of data lines  70   d  is electrically connected to sub-pixels  11  in the sub-display area d. A gate driving sub-circuit  21   d  is electrically connected to one group of gate lines  60   d  through the driving port  51   d,  and the group of gate lines  60   d  is electrically connected to the sub-pixels  11  in the sub-display area d. The source driving circuit  30  is electrically connected to one group of data lines  70   e  through the data port  52   e,  and the group of data lines  70   e  is electrically connected to sub-pixels  11  in the sub-display area e. A gate driving sub-circuit  21   e  is electrically connected to one group of gate lines  60   e  through the driving port  51   e,  and the group of gate lines  60   e  is electrically connected to the sub-pixels  11  in the sub-display area e. The source driving circuit  30  is electrically connected to one group of data lines  70   f  through the data port  52   f,  and the group of data lines  70   f  is electrically connected to sub-pixels  11  in the sub-display area f.

     It will be noted that the four groups of gate lines  60  and the four groups of data lines  70  are schematically shown in  FIG. 7  with only black lines. In practice, each group of gate lines  60  includes one or more gate lines, and each group of data lines  70  includes one or more data lines. In addition,  FIG. 7  only shows boundaries of the sub-display areas c, d, e, and f, does not show the sub-pixels  11  included in each sub-display area  10 , and also does not show a connection relationship between each group of gate lines  60  and the sub-pixels  11  in the corresponding sub-display area  10  and a connection relationship between each group of data lines  70  and the sub-pixel  11  in the corresponding sub-display area  10 . For parts not shown above, corresponding structures and descriptions in  FIG. 5, 6, 8 or 9  may be referred to. 
     In some embodiments of the present disclosure, there may be various connection relationships between the sub-pixels  11  in each sub-display area  10  and a corresponding group of gate lines  60  and a group of data lines  70 , as long as required signals may be transmitted to the sub-pixels  11  in the sub-display area  10  through the corresponding group of gate lines and the corresponding group of data lines, which is not limited in some embodiments of the present disclosure. 
     Referring to  FIG. 8 , in some embodiments, each sub-display area  10  includes the sub-pixels  11  in plurality of rows and a plurality of columns. In a case where the display panel  100  includes the at least two groups of gate lines  60  in one-to-one correspondence with the at least two sub-display areas  10  and the at least two groups of data lines  70  in one-to-one correspondence with the at least two sub-display areas  10 , for each sub-display area  10 , a number of gate lines included in one group of gate lines  60  corresponding to the sub-display area  10  is equal to a number of rows of the sub-pixels  11  included in the sub-display area  10 , and gate lines of the group of gate lines  60  corresponding to the sub-display area  10  are electrically connected to rows of the sub-pixels  11  included in the sub-display area  10  in a one-to-one correspondence manner. A number of data lines included in the group of data lines  70  corresponding to the sub-display area  10  is equal to a number of columns of the sub-pixels  11  included in the sub-display area  10 , and data lines of the group of data lines  70  corresponding to the sub-display area  10  are electrically connected to columns of the sub-pixels  11  included in the sub-display area  10  in a one-to-one correspondence manner. 
     One sub-display area  10  shown in  FIG. 8  is taken as an example. The sub-display area  10  includes six sub-pixels  11  in two rows and three columns, and a gate driving sub-circuit  21  and a source driving circuit that correspond to the sub-display area  10  are shown in  FIG. 8 . The gate driving sub-circuit  21  is electrically connected to the six sub-pixels  11  through one group of gate lines  60 , and the group of gate lines  60  includes two gate lines, i.e., a first gate line  61  and a second gate line  62 . The first gate line  61  is electrically connected to a first row of sub-pixels in the sub-display area  10 , and the gate driving sub-circuit  21  inputs a corresponding gate driving signal to the first row of sub-pixels through the first gate line  61 . The second gate line  62  is electrically connected to a second row of sub-pixels in the sub-display area  10 , and the gate driving sub-circuit  21  inputs a corresponding gate driving signal to the second row of sub-pixels through the second gate line  62 . Since each row of sub-pixels is electrically connected to a different gate line separately, it is possible to realize a progressive scanning driving for the sub-pixels  11  in the sub-display area  10  by controlling the timing of gate driving signals output by the first gate line  61  and the second gate line  62 . The source driving circuit  30  is electrically connected to the, six sub-pixels  11  through one group of data lines  70 . The group of data lines  70  includes three data lines, i.e., a first data line  71 , a second data line  72 , and a third data line  73  from left to right. The first data line  71  is electrically connected to a first column of sub-pixels in the sub-display area  10 , and the source driving circuit  30  inputs a corresponding second data signal to the first column of sub-pixels through the first data line  71 . The second data line  72  is electrically connected to a second column of sub-pixels in the sub-display area  10 , and the source driving circuit  30  inputs a corresponding second data signal to the second column of sub-pixels through the second data line  72 . The third data line  73  is electrically connected to a third column of sub-pixels in the sub-display area  10 , and the source driving circuit  30  inputs a corresponding second data signal to the third column of sub-pixels through the third data line  73 . 
     Herein, the number of gate lines included in one group of gate lines  60  corresponding to each sub-display area  10  is equal to the number of rows of the sub-pixels  11  included in the sub-display area  10 , and gate lines of the group of gate lines  60  corresponding to the sub-display area  10  are electrically connected to rows of the sub-pixels  11  included in the sub-display area  10  in a one-to-one correspondence manner. Therefore, the progressive scanning driving for the sub-pixels  11  in each sub-display area  10  may be realized by controlling the timing of one group of gate driving signals output by the gate driving sub-circuit  21 . In this case, the number of data lines included in one group of data lines  70  corresponding to the sub-display area  10  is equal to the number of columns of the sub-pixels  11  included in the sub-display area  10 , and data lines of the group of data lines  70  corresponding to the sub-display area  10  are electrically connected to columns of the sub-pixels  11  included in the sub-display area  10  in a one-to-one correspondence manner. In this way, a display function is realized, and it is beneficial to reduce the number of data lines corresponding to each sub-display area  10 , thereby simplifying the wiring in the display apparatus  1000 . 
     Referring to  FIG. 9 , in some embodiments, in a case where the display panel  100  includes the at least two groups of gate lines  60  in one-to-one correspondence with the at least two sub-display areas  10  and the at least two groups of data lines  70  in one-to-one correspondence with the at least two sub-display areas  10 , for each sub-display area  10 , one group of gate lines  60  corresponding to the sub-display area  10  includes one gate line, and the gate line corresponding to the sub-display area  10  is electrically connected to the plurality of sub-pixels  11  included in the sub-display area  10 . The number of data lines included in the group of data lines  70  corresponding to the sub-display area  10  is equal to the number of the sub-pixels  11  included in the sub-display area  10 , and data lines of the group of data lines  70  corresponding to the sub-display area  10  are electrically connected to the plurality of sub-pixels  11  included in the sub-display area  10  in a one-to-one correspondence manner. 
     One sub-display area  10  shown in  FIG. 9  is taken as an example. The sub-display area  10  includes six sub-pixels  11  in two rows and three columns, and a gate driving sub-circuit  21  and a source driving circuit  30  that correspond to the sub-display area  10  are shown in  FIG. 9 . The gate driving sub-circuit  21  is electrically connected to the six sub-pixels  11  through one group of gate lines  60 . The group of gate lines  60  includes one third gate line  63 , and the third gate line  63  is electrically connected to all the sub-pixels  11  in the sub-display area  10 . The gate driving sub-circuit  21  inputs a corresponding gate driving signal to the sub-pixels  11  through the third gate line  63 , thereby realizing a simultaneous driving for all the sub-pixels  11  in the sub-display area  10 . The source driving circuit  30  is electrically connected to the six sub-pixels  11  through one group of data lines  70 . The group of data lines  70  includes six data lines. i.e., a fourth data line  74 , a fifth data line  75 , a sixth data line  76 , a seventh data line  77 , an eighth data line  78  and a ninth data line  79 . The six data lines are electrically connected to the six sub-pixels  11  in a one-to-one correspondence manner. The source driving circuit  30  inputs corresponding second data signals to the six sub-pixels  11  through the six data lines respectively. 
     Herein, the sub-pixel  11   s  in each sub-display area  10  are electrically connected to a same gate line, and each sub-pixel  11  is electrically connected to one data line individually. Thus, the simultaneous driving for the sub-pixels  11  in each sub-display area  10  may be realized, which is beneficial to reduce a refresh time of each frame of the image on each sub-display area  10  and increase the frame rate. 
     Referring to  FIG. 10 , in some embodiments, the display apparatus  1000  further includes a timing controller  40  electrically connected to the gate driving circuit  20  and the source driving circuit  30 . Herein, the timing controller  40  is, for example, provided separately (as shown in  FIG. 10 ), or the timing controller  40  is integrated in the driving chip  50 , which is not limited in some embodiments of the present disclosure. 
     The timing controller  40  is configured to receive the source signals, and generate at least two groups of first control signals, at least two groups of second control signals, and at least two groups of first data signals according to the source signals, output the at least two groups of first control signals to the gate driving circuit  20 , and output the at least two groups of second control signals and the at least two groups of first data signals to the source driving circuit  30 . 
     The display apparatus  1000  shown in  FIG. 10  is taken as an example below to describe a principle of processing signals in some embodiments of the present disclosure in detail. Referring to  FIG. 10 , the display area  110  of the display panel  100  includes a×b sub-display areas  10  numbered from 1 to a×b and arranged in a matrix. Each sub-display area  10  includes the sub-pixels in m rows and n columns, that is, a resolution of each sub-display area  10  is m×n (for example, the resolution of each sub-display area  10  in  FIG. 10  is 2×3). 
       FIG. 11  is a timing signal diagram of the source signals input to the timing controller  40 . The source signals at least include signals that characterize timing and display data. Signals that characterize timing include various timing signals, such as a frame rate signal, a row clock signal, and a column clock signal. Different types of timing signals have different codes.  FIG. 11  illustrates an example of only an input frame signal, but the embodiments of the present disclosure does not limit to this. For the source signals,  FIG. 11  shows a signal line that abstractly characterizes the timing and a signal line that abstractly characterizes the display data. However, in the practical codes of the source signals, there are various signals, and a signal that characterizes the timing may also be internally installed in codes of signals that characterize the display data, which is not limited in some embodiments of the present disclosure. 
     Referring to  FIG. 11 , in the input frame signal, the time elapsed between two adjacent pulses is one frame period. In each frame period, the signals that characterize the display data in the source signals are input to the timing controller  40  according to a certain timing. The signals that characterize the display data include display data signals corresponding to images to be displayed on the a×b sub-display areas  10  in  FIG. 10  in sequence. For example, as shown in  FIG. 11 , a signal group  1  is a display data signal corresponding to the sub-display area  1 , and a signal group a is a display data signal corresponding to the sub-display area a, and a signal group a×b is a display data signal corresponding to the sub-display area a×b, and so on. A display data signal corresponding to each sub-display area  10  is sequentially input to the timing controller  40  in an order corresponding to the sub-display areas numbered from 1 to a×b. 
     The timing controller  40  stores the input signals, and reads the display data signals corresponding to the sub-display areas  10  according to a certain timing, and then arranges and converts the display data signals to generate a×b groups of first control signals corresponding to the a×b sub-display areas  10  respectively, a×b groups of second control signals corresponding to the a×b sub-display areas  10  respectively, and a×b groups of first data signals corresponding to the a×b sub-display areas  10  respectively, and outputs the a×b groups of first control signals to the a×b gate driving sub-circuits  21  in the gate driving circuit  20  in a one-to-one correspondence manner. Optionally, in a case where the gate driving sub-circuit  21  is the GOA sub-circuit, one group of first control signals input to any gate driving sub-circuit  21  includes one group of clock signals (CLK signal group). The group of clock signals includes one or more clock signals required to control the GOA sub-circuit, and the group of clock signals is configured to control an opening sequence and time of each row of sub-pixels  11  in a corresponding sub-display area  10 . 
     The timing controller  40  further outputs the a×b groups of second control signals and the a×b groups of first data signals to the source driving circuit  30 . A second control signal includes, for example, a timing control signal. A first data signal is, for example, a data signal related to an image displayed on each sub-display area  10 . 
     After receiving the a×b groups of second control signals and the a×b groups of first data signals, the source driving circuit  30  converts the received a×b groups of first data signals according to the a×b groups of second control signals. For example, groups of first data signals are processed by signal selection, signal arrangement, digital-to-analog conversion, storage to form a×b groups of second data signals. Then, the source driving circuit  30  outputs the a×b groups of second data signals to the corresponding sub-display areas  10  according to a certain timing. For example, referring to  FIG. 12 ,  FIG. 12  is a diagram showing a theoretical principle where a plurality of groups of second data signals corresponding to  FIG. 11  are output to the sub-display areas  10 . In  FIG. 12 , a data group  1  is a group of second data signals corresponding to the sub-display area  1 , and a data group a is a group of second data signals corresponding to the sub-display area a, and the data group a×b is a group of second data signals corresponding to the sub-display area a×b, and so on. The source driving circuit  30  outputs the groups of second data signals to the corresponding sub-display areas  10  in a one-to-one correspondence manner, and each output group of second data signals includes, for example, a driving current signal or a driving voltage signal. 
     The resolution of each sub-display area  10  in the a×b sub-display areas is m×n. In a case where the frame rate of each sub-display area  10  is the same. output frame signals corresponding to all the sub-display areas  10  are synchronized (as shown in  FIG. 12 ), and an output resolution per frame of the source driver circuit  30  is (m×a×b)×n. In a case where the source driving circuit  30  is integrated in the driving chip  50 , an output resolution of each data port  52  is m×n. 
     In a case where the frame rate of each sub-display area  10  is different, the output frame signals corresponding to all the sub-display areas  10  are asynchronous. For example, in a case where the frame rate of each sub-display area  10  is different, in the source signals, signals that characterize the display data may be input to the timing controller  40  according to one timing or one frame rate, and then the plurality of groups of second data signals are output from the timing controller  40  according to another timing or another frame rate. The row effective time and column effective time that correspond to different sub-display areas  10  may be different, so that different sub-display areas  10  may display images at different frame rates. 
     The display apparatus  1000  in some embodiments of the present disclosure is, for example, an OLED display apparatus, a Mini LED display apparatus, a Micro LED display apparatus, an LCD display apparatus, an electronic paper, a mobile phone, a tablet computer, a television, a displayer, a notebook computer, a digital photo frame, a navigator or any product or component that has a display function, which is not limited in some embodiments of the present disclosure. 
     The display apparatus  1000  in any of the embodiments may be applied to application scenarios such as the AR display, the VR display, or the rotating display. In some examples, a basic model of a rotating display apparatus  1000  may be referred to  FIGS. 13 to 15 . The rotating display apparatus includes a rotation axis  200  (referred to  FIG. 15 ) and the display panel  100 . The display panel  100  is capable of rotating around the rotation axis  200  rapidly, so as to form a cylindrical three-dimensional display space with a certain diameter and height (referred to  FIG. 13 ). When the cylindrical three-dimensional display space is formed, a plurality of two-dimensional dot matrix pictures may be sequentially displayed at different spatial positions. 
     The display panel  100  of the rotating display apparatus includes a plurality of sub-pixels  11  arranged in rows and columns at equal intervals. For clarity, a size and an adjacent space of each sub-pixel  11  are enlarged in  FIG. 13 . During a rotation of the display panel  100  around the rotation axis  200  for display, due to a persistence of vision effect of the human eyes, all the sub-pixels  11  scattered in the space will be correspondingly regarded as voxels (a voxel being the smallest component of a three-dimensional image in a three-dimensional space) that “residue” in the space when they are displayed. In addition, a plurality of voxels  12  correspondingly formed by a plurality of sub-pixels  11  in a same row and different columns are distributed on circles with a same height and different radiuses, and a plurality of voxels  12  correspondingly formed by a plurality of sub-pixels  11  in a same column and different rows are distributed on circles with a same radius and different heights, all the sub-pixels form a three-dimensional voxel dot matrix together. 
     During the rotation of the display panel  100  around the rotation axis  200  for display, for an arc length L stroked by any sub-pixel  11  in a certain unit time, the greater a perpendicular distance between the sub-pixel  11  and the rotation axis  200  is, the greater the arc length L is. Therefore, the voxels  12  in the three-dimensional voxel dot matrix have a same density in a direction parallel to the rotation axis  200 , and have different densities in a direction perpendicular to the rotation axis  200 . In addition, the voxels  12  in the three-dimensional voxel dot matrix present a distribution characteristic of being dense inside and sparse outside. That is, the voxels  12  become increasingly sparse along a direction perpendicular to and away from the rotation axis  200 . In this case, if the frame rates of all the sub-pixels  11  in the display panel  100  are synchronized, a viewed image will appear bright inside and dark outside (referred to  FIG. 14 ). Thus, it is hard to realize voxel uniformity, thereby affecting the viewing experience of the users. 
     Based on this, the display apparatus  1000  provided by some embodiments of the present disclosure further includes the rotation axis  200 , and the display panel  100  is configured to be rotatable around the rotation axis  200 . 
     Herein, referring to  FIG. 15 , the rotation axis  200  may be disposed on an edge of the display panel  100 , and the display panel  100  is capable of rotating around the rotation axis  200  (referred to a direction indicated by the arrow in  FIG. 15 ). Or, referring to  FIG. 16 , the rotation axis  200  may be disposed at a central axis of the display panel  100 , and the display panel  100  is capable of rotating around the rotation axis  200  (referred to a direction indicated by the arrow in  FIG. 16 ). Some embodiments of the present disclosure do not limit thereto. 
     The display panel  100  has at least two brightness adjustment areas  130 , a length direction of each brightness adjustment area  130  of the at least two brightness adjustment areas  130  is parallel to the rotation axis  200 , and the at least two brightness adjustment areas  130  are arranged in parallel along a direction perpendicular to the rotation axis  200 . Each brightness adjustment area  130  includes at least one sub-display area  10 . For example, referring to  FIG. 15 , the display apparatus  1000  includes the display panel  100  and the rotation axis  200  disposed at the edge of the display panel  100 . The display panel  100  includes three brightness adjustment areas  130 , i.e.,  131 ,  132 , and  133 . The length direction of each brightness adjustment area  130  is parallel to the rotation axis  200 , and the three brightness adjustment areas  130  are arranged in parallel along the direction perpendicular to the rotation axis  200 . Each brightness adjustment area  130  includes three sub-display areas  10 . 
     The source driving circuit  30  of the rotating display apparatus is further configured to adjust groups of second data signals to be output to sub-display areas  10  in a corresponding brightness adjustment area  130  separately according to a preset brightness parameter of each brightness adjustment area  130 , so that an average display brightness of the at least two brightness adjustment areas  130  are the same or approximately the same. The brightness parameter of each brightness adjustment area  130  increases sequentially along the direction perpendicular to the rotation axis  200  and progressively away from the rotation axis  200 . Herein, a display brightness refers to an overall brightness of the display image seen by the human eyes, and an average display brightness of any brightness adjustment area  130  refers to an overall brightness of the image displayed on the brightness adjustment area  130  seen by the human eyes. 
     There may be many types of brightness parameters according to different types of display apparatuses. For example, in a case where the display apparatus  1000  is a current-driven display apparatus such as the OLED display apparatus, the Mini LED display apparatus, or the Micro LED display apparatus, the brightness parameter is, for example, a duty ratio coefficient of each second data signal in each group of second data signal corresponding to each sub-display area  10  in a target brightness adjustment area  130 . In a case where the display apparatus  1000  is a voltage-driven display apparatus such as the LCD display apparatus, the brightness parameter is, for example, a gray coefficient of each second data signal in each group of second data signals corresponding to each sub-display area  10  in the target brightness adjustment area  130 . 
     The display panel  100  is divided into different brightness adjustment areas  130  in some embodiments of the present disclosure. On the basis of driving each sub-display area  10  in the display panel  100  separately, each group of second data signals to be output to each sub-display area  10  of the corresponding brightness adjustment area  130  is adjusted separately, and the brightness parameter of each brightness adjustment area  130  is set to increase along the direction perpendicular to and away from the rotation axis  200 . Therefore, the average display brightness of each of the different brightness adjustment areas  130  is adjusted, so that an average display brightness of a brightness adjustment area  130  closer to the rotation axis  200  as viewed by the human eyes is proximate to or equal to an average display brightness of a brightness adjustment area  130  further away from the rotation axis  200 . Thus, a case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying the image is improved, and the brightness of the stereoscopic image viewed by a viewer is more uniform, thereby realizing a better voxel uniformity effect of the rotating display apparatus. 
     Referring to  FIG. 17 , some embodiments of the present disclosure provide a driving method of, a display apparatus applied to the display apparatus  1000  of any of the above embodiments. The driving method includes S 1 . 
     In S 1 , each gate driving sub-circuit  21  included in the gate driving circuit  20  receives one group of first control signals, generates one group of gate driving signals, and outputs the group of gate driving signals to a plurality of sub-pixels  11  included in a corresponding sub-display area  10  in the display panel  100 . 
     In the driving method, the corresponding sub-display area  10  is driven by one gate driving sub-circuit  21 , so that each sub-display area  10  may be driven separately, and sub-pixels  11  in different sub-display areas  10  may be scanned synchronously in one frame period. In addition, the different sub-display areas  10  may display images at different frame rates, and the different sub-display areas  10  may be asynchronously scanned and refreshed. 
     In some embodiments, in a case where the display apparatus  1000  includes the source driving circuit  30 , with continuous reference to  FIG. 17 , the driving method in the embodiments of the present disclosure further includes S 21  and S 22 . 
     In S 21 , the source driving circuit  30  receives at least two groups of second control signals and at least two groups of first data signals, and converts the at least two groups of first data signals into at least two groups of second data signals in one-to-one correspondence with the at least two sub-display areas  10  in the display panel  100  according to the at least two groups of second control signals. 
     In S 22 , each group of second data signals is output to a plurality of sub-pixels  11  included in a corresponding sub-display area  10 . 
     In some embodiments, in a case where the display apparatus  1000  is a rotating display apparatus, the display apparatus  1000  further includes a rotation axis  200 , and the display panel  100  is configured to be rotatable around the rotation axis  200 . The display panel  100  has at least two brightness adjustment areas  130 , and a length direction of each brightness adjustment area  130  of the at least two brightness adjustment areas  130  is parallel to the rotation axis  200 , and the at least two brightness adjustment areas  130  are arranged in parallel along a direction perpendicular to the rotation axis  200 . Each brightness adjustment area  130  includes at least one sub-display area  10 . Referring to  FIG. 18 , before each group of second data signals is output to the plurality of sub-pixels  11  included in the corresponding sub-display area  10 , the driving method in the embodiments of the present, disclosure further includes S 23 . 
     In S 23 , the source driving circuit  30  adjusts the at least two groups of second data signals obtained by conversion separately according to a preset brightness parameter of each brightness adjustment area  130 , so that an average display brightness of each brightness adjustment area  130  of the at least two brightness adjustment areas  130  is the same or approximately the same. The brightness parameter of each brightness adjustment area  130  increases sequentially along a direction perpendicular to the rotation axis  200  and progressively away from the rotation axis  200 . 
     It is worth mentioning that the preset brightness parameter of each brightness adjustment area  130  is stored, for example, in the source driving circuit  30 , so that the brightness parameter may be invoked by the source driving circuit  30 . 
     There may be many types of brightness parameters according to different types of display apparatuses. 
     In some embodiments, the display apparatus  1000  includes a current-driven display apparatus such as an OLED display apparatus, a Mini LED display apparatus, or a Micro LED display apparatus. In the above display apparatus, an effective brightness of each sub-pixel  11  in one frame period is related to a duty ratio of a second data signal received by the sub-pixel  11 . The duty ratio of the second data signal determines an effective lighting time of a light-emitting device in a corresponding sub-pixel  11 , and the effective lighting time of a plurality of sub-pixels  11  in each brightness adjustment area  130  corresponds to the overall brightness (average display brightness) of the image displayed on the brightness adjustment area  130 . Therefore, duty ratios of second data signals corresponding to the plurality of sub-pixels  11  in the same brightness adjustment area  130  are adjusted according to a certain ratio, and the average display brightness of the brightness adjustment area  130  may be adjusted. It will be noted that the frame rates of the sub-display areas  10  included in the same brightness adjustment area  130  are synchronized, and the frame rates corresponding to different brightness adjustment areas  130  may be the same or different. 
     Based on this, the brightness parameter includes a duty ratio coefficient of each second data signal in each group of second data signals obtained by conversion and corresponding to each sub-display area  10  in a target brightness adjustment area  130 . Along the direction perpendicular to the rotation axis  200  and progressively away from the rotation axis  200 , a ratio of duty ratio coefficients of brightness adjustment areas  130  is inversely related to a ratio of the average display brightness of the brightness adjustment areas  130  in a case where the at least two groups of second data signals obtained by conversion are not adjusted separately. That is to say, in a case where the groups of second data signals obtained by conversion are not adjusted separately, the greater the average display brightness of the target brightness adjustment area  130  is, the smaller the duty ratio coefficient corresponding to the target brightness adjustment area  130  during adjustment is. In the case where the groups of second data signals obtained by conversion are not adjusted separately, the darker the average display brightness of the target brightness adjustment area  130  is, the greater the duty ratio coefficient corresponding to the target brightness adjustment area  130  during adjustment is. After such adjustment, an average display brightness of a brightness adjustment area  130  closer to the rotation axis  200  viewed by the human eyes is proximate to or equal to an average display brightness of a brightness adjustment area  130  further away from the rotation axis  200 . Thus, the case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying an image is improved, and the brightness of the stereoscopic image viewed by the viewer is more uniform, thereby realizing a good voxel uniformity effect of the rotating display apparatus. 
     In some embodiments, referring to  FIG. 19 , the at least two groups of second data signals obtained by conversion are adjusted separately according to the preset brightness parameter of each brightness adjustment area  130 , which includes S 231 . 
     In S 231 , the duty ratio of each second data signal in each group of second data signals obtained by conversion and corresponding to each sub-display area  10  in each brightness adjustment area  130  is multiplied by the duty ratio coefficient of the brightness adjustment area  130 , so as to obtain each second data signal in each adjusted group of second data signals corresponding to each sub-display area  10  in the brightness adjustment area  130 . 
     A small desktop-class rotating display apparatus with a close-range edge axis is taken as an example. Referring to  FIG. 15 , the display panel  100  of the display apparatus  1000  includes three brightness adjustment areas  130 , i.e.,  133 ,  132 , and  131  that are sequentially away from the rotation axis  200 . The length direction of each brightness adjustment area  130  is parallel to the rotation axis  200 , and the three brightness adjustment areas  130  are, arranged in parallel along the direction perpendicular to the rotation axis  200 . Each brightness adjustment area  130  includes three sub-display areas  10 . 
     The source driving circuit  30  stores preset duty ratio coefficients of second data signals corresponding to sub-pixels  11  in each brightness adjustment area  130  of the three brightness adjustment areas  130 , that is, a duty ratio coefficient of each second data signal in groups of second data signals corresponding to the sub-display areas  10  in each brightness adjustment area  130 . According to actual needs, the duty ratio coefficients of the second data signals corresponding to the sub-pixels  11  in each brightness adjustment area  130  may be obtained by preset optical simulation and actual brightness testwhich is not limited by some embodiments of the present disclosure. 
     A perpendicular distance between the brightness adjustment area  131  and the rotation axis  200  is the largest. Optionally, a duty ratio coefficient of a second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131  is preset to be 1. That is, the source driving circuit  30  does not adjust and directly outputs three groups of second data signals obtained by conversion and corresponding to three sub-display areas  10  in the brightness adjustment area  131 . Of course, the duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131  may also be appropriately increased in a case where the data does not overflow. For example, the duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131  is preset to be 1.1. The source driving circuit  30  processes the three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjusting area  131 , and the duty ratios of the three groups of second data signals are separately multiplied by 1.1, so as to obtain each second data signal in the three adjusted groups of second data signals in one-to-one correspondence with the three sub-display areas  10  in the brightness adjustment area  131 . The adjusted second data signal is, for example, a pulse width modulation (PWM) control signal. 
     A perpendicular distance between the brightness adjustment area  132  and the rotation axis  200  is slightly less than the perpendicular distance between the brightness adjustment, area  131  and the rotation axis  200 . Therefore, a duty ratio coefficient of a second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  132  may be preset to be 0.6 to 0.9 times of the preset duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131 . Optionally, the duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  132  is preset to be 0.8, and the source driving circuit  30  processes three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjusting area  132 , and the duty ratios of the three groups of second data signals are separately multiplied by 0.8, so as to obtain each second data signal in the three adjusted groups of second data signals in one-to-one correspondence with the three sub-display areas  10  in the brightness adjustment area  132 . 
     A perpendicular distance between the brightness adjustment area  133  and the rotation axis  200  is the smallest. Therefore, a duty ratio coefficient of a second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  133  needs to be less than the duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  132 , i.e., less than 0.6 times of the preset duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131 . Optionally, the duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  133  is preset to be 0.4, and the source driving circuit  30  processes three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjusting area  133 , and the duty ratios of the three groups of second data signals are separately multiplied by 0.4, so as to obtain each second data signal in the three adjusted groups of second data signals in one-to-one correspondence with the three sub-display areas  10  in the brightness adjustment area  133 . Herein, the preset duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  133  should not be too low, for example, not less than 0.3 times of the preset duty ratio coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131 , so as to prevent the sub-pixels  11  in the display apparatus from excessively being in a low brightness state, and affecting the display effect of the display apparatus. 
     In some embodiments of the present disclosure, by using the persistence of vision effect of the human eyes, the duty ratio coefficient of each brightness adjustment area  130  increases sequentially along the direction perpendicular to the rotation axis  200  and progressively away from the rotation axis  200 . The source driving circuit  30  adjusts the duty ratios of the second data signals corresponding to the plurality of sub-pixels  11  in each brightness adjustment area  130  according to a certain ratio, so as to realize an adjustment of the average display brightness of each brightness adjustment area  130 . Therefore, the average display brightness of the brightness adjustment area  130  closer to the rotation axis  200  viewed by the human eyes is proximate to the average display brightness of the brightness adjustment area  130  further away from the rotation axis  200 . Thus, the case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying images is improved, and the brightness of the stereoscopic images viewed by the viewer is more uniform, thereby realizing a good voxel uniformity effect of the rotating display apparatus. 
     In some other embodiments, the display apparatus  1000  includes a voltage-driven display apparatus such as an LCD display apparatus. In this case, the brightness parameter includes a gray coefficient of each second data signal in each group of the second data signal obtained by conversion and corresponding to each sub-display area  10  in the target brightness adjustment area  130 . Along the direction perpendicular to the rotation axis  200  and progressively away from the rotation axis  200 , a ratio of gray coefficients of brightness adjustment areas  130  is inversely related to a ratio of the average display brightness of the brightness adjustment areas  130  in a case where the at least two groups of second data signals obtained by conversion are not adjusted separately. That is to say, in a case where the groups of second data signals obtained by conversion are not adjusted separately, the greater an average display brightness of the target brightness adjustment area  130  is, the smaller the gray coefficient corresponding to the target brightness adjustment area  130  during adjustment is. In the case where the groups of second data signals obtained by conversion are not adjusted separately, the darker the average display brightness of the target brightness adjustment area  130  is, the greater the gray coefficient corresponding to the target brightness adjustment area  130  during adjustment is. After such adjustment, an average display brightness of a brightness adjustment area  130  closer to the rotation axis  200  viewed by the human eyes is proximate to or equal to an average display brightness of a brightness adjustment area  130  further away from the rotation axis  200 . Thus, the case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying an image is improved, and the brightness of the stereoscopic image viewed by the viewer is more uniform, thereby realizing a good voxel uniformity effect of the rotating display apparatus. 
     Herein, for the LCD display apparatus, the second data signal is, for example, a signal representing a gray value. 
     In some embodiments, referring to  FIG. 20 , the at least two groups of second data signals obtained by conversion are adjusted separately according to the preset brightness parameter of each brightness adjustment area  130 , which includes S 232 . 
     In S 232 , the gray value represented by each second data signal in each group of second data signals obtained by conversion and corresponding to each sub-display area  10  in each brightness adjustment area  130  is multiplied by a gray coefficient of the brightness adjustment area  130 , so as to obtain each second data signal in each adjusted group of second data signals corresponding to each sub-display area  10  in the brightness adjustment area  130 . The brightness of any sub-pixel  11  in the LCD display apparatus is related to the magnitude of the gray value represented by the second data signal received by the sub-pixel  11 . The greater the gray value corresponding to the sub-pixel  11  is, the greater a deflection angle of liquid crystals in the sub-pixel  11  is, and the greater the brightness is. 
     The display apparatus  1000  shown in  FIG. 15  is taken as an example. The display apparatus  1000  is an LCD display apparatus, and the display panel  100  thereof includes three brightness adjustment areas  130 , i.e.,  133 ,  132 , and  131  that are sequentially away from the rotation axis  200 . A length direction of each brightness adjustment area  130  is parallel to the rotation axis  200 , and the three brightness adjustment areas  130  are arranged in parallel along a direction perpendicular to the rotation axis  200 . Each brightness adjustment area  130  includes three sub-display areas  10 . 
     The source driving circuit  30  stores preset gray coefficients of the second data signals corresponding to the sub-pixels  11  in each brightness adjustment area  130  of the three brightness adjustment areas  130 , that is, a gray coefficient of each second data signal in groups of second data signals corresponding to the sub-display areas  10  in each brightness adjustment area  130 , according to actual needs, the gray coefficients of the second data signals corresponding to the sub-pixels  11  in each brightness adjustment area  130  may be obtained by preset optical simulation and actual brightness testwhich is not limited by some embodiments of the present disclosure. 
     A perpendicular distance between the brightness adjustment area  131  and the rotation axis  200  is the largest. Optionally, a gray coefficient of a second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131  is preset to be 1. That is, the source driving circuit  30  does not adjust and directly outputs gray values represented by three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjustment area  131 . Of course, the gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131  may also be appropriately increased in a case where the data does not overflow. For example, the gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131  is preset to be 1.2. The source driving circuit  30  processes the three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjusting area  131 , and the gray values represented by the three groups of second data signals are separately multiplied by 1.2, so as to obtain each second data signal in the three adjusted groups of second data signals in one-to-one correspondence with the three sub-display areas  10  in the brightness adjustment area  131 . 
     A perpendicular distance between the brightness adjustment area  132  and the rotation axis  200  is slightly less than the perpendicular distance between the brightness adjustment area  131  and the rotation axis  200 . Therefore, a gray coefficient of a second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  132  may be preset to be 0.6 to 0.9 times of the preset gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131 . Optionally, the gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  132  is preset to be 0.7, and the source driving circuit  30  processes three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjusting area  132 , and the gray values represented by the three groups of second data signals are separately multiplied by 0.7, so as to obtain each second data signal in the three adjusted groups of second data signals in one-to-one correspondence with the three sub-display areas  10  in the brightness adjustment area  132 . 
     A perpendicular distance between the brightness adjustment area  133  and the rotation axis  200  is the smallest. Therefore, a gray coefficient of a second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  133  needs to be less than the gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  132 , i.e., less than 0.6 times of the preset gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131 . Optionally, the gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  133  is preset to be 0.5, and the source driving circuit  30  processes three groups of second data signals obtained by conversion and corresponding to the three sub-display areas  10  in the brightness adjusting area  133 , and the gray values represented by the three groups of second data signals are separately multiplied by 0.5, so as to obtain each second data signal of the three adjusted groups of second data signals in one-to-one correspondence with the three sub-display areas  10  in the brightness adjustment area  133 . Herein, the preset gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  133  should not be too low, for example, not less than 0.5 times of the preset gray coefficient of the second data signal corresponding to each sub-pixel  11  in the brightness adjustment area  131 , so as to prevent the sub-pixels  11  in the display apparatus from excessively being in a low brightness state, thereby affecting the display effect of the display apparatus. 
     In some embodiments of the present disclosure, by using the persistence of vision effect of the human eyes, the, gray coefficient of each brightness adjustment area  130  increases sequentially along the direction perpendicular to the rotation axis  200  and progressively away from the rotation axis  200 . The source driving circuit  30  adjusts the gray values represented by the second data signals corresponding to the plurality of sub-pixels  11  in each brightness adjustment area  130  according to a certain ratio, so as to realize an adjustment of the average display brightness of each brightness adjustment area  130 . Therefore, the average display brightness of the brightness adjustment area  130  closer to the rotation axis  200  viewed by the human eyes is proximate to or equal to the average display brightness of the brightness adjustment area  130  further away from the rotation axis  200 . Thus, the case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying images is improved, and the brightness of the stereoscopic images viewed by the viewer is more uniform, thereby realizing a good voxel uniformity effect of rotating display apparatus. 
     Referring to  FIG. 22 , in some embodiments, the display panel  100  has at least two different levels of viewing areas  140 , and each level of the at least two different levels of viewing areas  140  includes at least one sub-display area  10 . Referring to  FIG. 21 , each gate driving sub-circuit  21  outputs one group of gate driving signals to a plurality of sub-pixels  11  included in a corresponding sub-display area  10  in the display panel  100 , which includes S 11 . In S 11 , each gate driving sub-circuit  21  corresponding to each sub-display area  10  in viewing area(s)  140  of the same level outputs the group of gate driving signals representing the same frame rate to the plurality of sub-pixels  11  included in the corresponding sub-display area  10 , so as to make a frame rate of an image displayed on each sub-display area  10  in the viewing area(s)  140  of the level equal; and gate driving sub-circuits  21  corresponding to sub-display areas  10  in viewing areas  140  of different levels output groups of gate driving signals representing different frame rates to a plurality of sub-pixels  11  included in corresponding sub-display areas  10 , so as to make frame rates of images displayed on the viewing areas  140  of different levels different. Herein, a frame rate of an image displayed on each viewing area  140  progressively decreases as a level of the viewing area  140  progressively increases. 
     In some embodiments of the present disclosure, according to actual needs, a high frame rate may be set for sub-display areas  10  in a part of the display area (for example, the main viewing area) in an image, and a low frame rate may be set for sub-display areas  10  in another part of the display area (for example, the secondary viewing area) in the image. Compared with a manner of setting a high frame rate for the whole display panel  100 , a data amount of the source signals may be effectively reduced, thereby effectively reducing the overall bandwidth of data transmission. 
     For example, referring to the display apparatus shown in  FIG. 22 , the display apparatus may be applied to application scenarios such as the AR display or the VR display. The display panel  100  of the display apparatus has three different levels of viewing areas  140 , i.e., the levels □, □, and □. Positions of the viewing areas  140  of the levels are shown in  FIG. 22 . In the three different levels of viewing areas  140 , the level I viewing area  140  includes one sub-display area  10 , and one gate driving sub-circuit  21  corresponding to the sub-display area  10  outputs one group of gate driving signals representing a frame rate of 240 Hz to a plurality of sub-pixels  11  included in the sub-display area  10 . The level □ viewing area  140  includes four sub-display areas  10 , and four gate driving sub-circuits  21  corresponding to the four sub-display areas  10  respectively output four groups of gate driving signals representing a frame rate of 120 Hz to a plurality of sub-pixels  11  included in corresponding sub-display areas  10 . The level □ viewing area  140  includes four sub-display areas  10 , and four gate driving sub-circuits  21  corresponding to the four sub-display areas  10  respectively output four groups of gate driving signals representing a frame rate of 90 Hz to a plurality sub-pixels  11  included in corresponding sub-display areas  10 . Therefore, a frame rate of an image displayed on the sub-display area  10  in the level I viewing area  140  is 240 Hz, and a frame rate of images displayed on the four sub-display areas  10  in the II level viewing area  140  is 120 Hz, and a frame rate of images displayed on the four sub-display areas  10  in the □ viewing area  140  is 90 Hz. It is realized that when the viewer views the display images, the frame rate of the image proximate to a center of the display panel  100  is high, and the frame rate of the image proximate to an edge of the display panel  100  is low. Compared with the manner of setting a high frame rate for the whole display panel  100 , the data amount of the source signals may be effectively reduced, thereby effectively reducing the overall bandwidth of data transmission. 
     For example, referring to the display apparatus  1000  shown in  FIG. 16 , the display apparatus  1000  may be applied to application scenarios such as the rotating display. The display panel  100  of the display apparatus has three different levels of viewing areas  140 , i.e., the levels I, □, and □. Positions of the viewing areas  140  of levels are shown in  FIG. 16 . In the three different levels of viewing areas  140 , the level I viewing area  140  includes six sub-display areas  10 , and six gate driving sub-circuits  21  corresponding to the six sub-display areas  10  respectively output six groups of gate driving signals representing a frame rate of 10000 Hz to a plurality of sub-pixels  11  included in corresponding sub-display areas  10 . The level □ viewing area  140  includes six sub-display areas  10 , and six gate driving sub-circuits  21  corresponding to the six sub-display areas  10  respectively output six groups of gate driving signals representing a frame rate of 7000 Hz to a plurality of sub-pixels  11  included in corresponding sub-display areas  10 . The level □ viewing area  140  includes six sub-display areas  10 , and six gate driving sub-circuits  21  corresponding to the six sub-display areas  10  respectively output six groups of gate driving signals representing a frame rate of 5000 Hz to a plurality sub-pixels  11  included in corresponding sub-display areas  10 . Therefore, a frame rate of images displayed on the six sub-display areas  10  in the level I viewing area  140  is 10000 Hz, and a frame rate of images displayed on the six sub-display areas  10  in the level II viewing area  140  is 7000 Hz, and a frame rate of images displayed on the six sub-display areas  10  in the level □ viewing area  140  is 5000 Hz. It is realized that when the viewer views the display images, the frame rate of the display image progressively increases in a direction away from the rotation axis  200 . 
     On one hand, compared with the manner of setting a high frame rate for the whole display panel  100 , the above manner of setting different levels of viewing areas  140  corresponding to different frame rates may effectively reduce the data amount of the source signals input to the display apparatus, thereby effectively reducing the overall bandwidth of data transmission. On another hand, due to the persistence of vision effect of the human eyes, for a same image, if the image is displayed at a high frame rate, the overall brightness of the image viewed by the human eyes is bright; if the image is displayed at a low frame rate, the overall brightness of the image viewed by the human eyes is dark. Therefore, during the rotating display, if the frame rates of images displayed by all the sub-pixels  11  in the display panel  100  are synchronized, the images viewed by the human eyes will appear bright inside and dark outside. In some embodiments of the present disclosure, different frame rates are set for the viewing areas  140  of different levels, and the frame rate of an image displayed by each viewing area  140  along the direction away from the rotation axis  200  progressively increases, so that the average display brightness of the viewing areas  140  of different levels may be adjusted. As a result, the average display brightness of the viewing area  140  closer to the rotation axis  200  viewed by the human eyes is proximate to the average display brightness of the viewing area  140  further away from the rotation axis  200 . Thus, a case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying images is improved, and the brightness of the stereoscopic images viewed by the viewer is more uniform, thereby realizing a good voxel uniformity effect of rotating display apparatus. 
     It is worth mentioning that in a process of improving the case where the three-dimensional voxel dot matrix of the display apparatus is bright inside and dark outside during displaying images, it is possible to adopt a method of adjusting the brightness parameter of the second data signal, or adopting a method of setting different frame rates for the different levels of the viewing areas  140 . Of course, the above two methods may also be adopted at the same time, which is not limited in some embodiments of the present disclosure.
