DETAIL DESCRIPTION OF EMBODIMENTS

In order to make the technical solutions of the present disclosure better be understood by those skilled in the art, the present disclosure is further described in detail with reference to the accompanying drawings and the detailed description below.

The present disclosure will be described in more detail below with reference to the accompanying drawings. Like elements are denoted by like reference numerals throughout the drawings. For purposes of clarity, the portions in the drawings are not drawn to scale. Moreover, certain well-known elements may not be shown in the drawings.

In the following description, many specific details are set forth, such as structures, materials, sizes, processing processes and processing techniques of components, in order to provide a more thorough understanding of the present disclosure. However, as will be understood by those skilled in the art, the present disclosure may be implemented without these specific details.

As shown inFIG.1andFIG.2, a rotational stereoscopic display is a display technology of true three-dimensional display, which implements the effect of true three-dimensional display by addressing voxels in space in combination with the principle of persistence of vision of human eyes. Specifically, the rotational display panel includes a plurality of pixel units arranged in an array, may rotate at a specific angular speed by taking a line which is parallel to the columns of the pixel units and passes through the rotational display screen as a rotating shaft. Each rotation of a specific angle corresponds to an electronic frame, the rotational display device displays different images in different electronic frames, and a cylindrical display space is formed in a very short time, so as to implement stereoscopic display (three-dimensional display of a model) in combination with principle of persistence of vision of human eyes.

As shown inFIG.1andFIG.2, the main parameters of the rotational display panel include body frame, body frame frequency, electronic frame, and electronic frame frequency. The body frame represents that the rotational display panel make a full revolution, namely rotates for 360 degrees, such that a 3D model image is refreshed; the body frame frequency represents the number of refreshed body frames within one second, namely the number of turns of the rotational display panel within one second; the electronic frame represents an image displayed at every rotation of a particular angle in a body frame; the electronic frame frequency represents the number of electronic frames refreshed in one second, i.e., the screen refresh rate.

As shown inFIG.3, the process of generating a display model for stereoscopic display of a rotational display panel specifically includes the following steps: 1. display model scaling: drawing a 3D model by using modeling software, and scaling the 3D model in combination with the actual size of the cylindrical display space; 2. model slicing: rotating the rotational display panel to different angles, and respectively slicing the 3D model at the different angles to obtain slice images, namely images containing the model profile; 3. image arrangement: arranging all the slice images according to the rotated angles to obtain an image sequence. The rotational display panel displays the images according to the sequence in the rotation process.

In a rotational display panel in the related art, the rotational display panel is formed by a plurality of display units (sub-pixels) arranged in an array, and the display units are driven by a source drive chip and a gate drive chip, so that the rotational display panel generates different display images in different electronic frames, so as to implement stereoscopic display.

For example, the rotational display panel has 96×96 display units therein. The body frame frequency is 30 Hz; and a total of 180 electronic frames are refreshed in a body frame, namely the display panel refreshes the display image once every 2 degrees. In this case, the electronic frame frequency (or screen refresh rate) is: 30 Hz*180=5400 Hz. If one display unit is turned on at 16-bit grayscale, the transmission bandwidth required to display the image is: 16 bit*(96*96)*5400 Hz=0.7962624 Gbps. It can be seen that the amount of display data required by the rotational display panel during the display is very large.

In order to further improve the display effect of the rotational display panel, and implement color display, the resolution of the display panel is 100*200; the color level of the pixel point is 16 bit*3(RGB); the body frame frequency is 60 Hz; the number of the electronic frames is 360; the refresh rate of the panel is 60 Hz*360=21600 Hz; the transmission bandwidth is (16 bit*3)*(100*200)*21600 Hz=20.736 Gbps. If a single driving chip (Driver IC) operates with a transmission rate of 16 Mbps, 20.736 Gbps/16 Mbps=1296 driving ICs are required in total, as shown inFIG.4, which is difficult to implement in the rotational display panel.

Aiming at the problem that the transmission bandwidth required by the display data is large in the rotational display panel, embodiments of the present disclosure provide the following technical solutions.

In a first aspect, as shown inFIG.5, the present embodiment provides a display panel, including: a plurality of pixel units1and a plurality of pixel driving chips2. Each of the plurality of pixel units1includes at least two sub-pixels10, the plurality of pixel driving chips2are arranged in an array, the pixel driving chips2are in one-to-one correspondence with the pixel units1, and the pixel driving chip2is configured to provide a driving signal to a corresponding pixel unit1.

The pixel unit1is a structure configured to emit display light in a display panel; the pixel driving chip2is a structure configured to provide the driving signal to the pixel unit1in the display panel to enable the pixel unit1to emit the display light. The plurality of pixel units1are arranged in an array, and each pixel unit1includes at least two sub-pixels10. It should be noted that, in the display process of the display panel, each sub-pixel10requires a corresponding driving signal.

Since the pixel units1are in one-to-one correspondence with the pixel driving chips2, each pixel driving chip2is only required to provide the driving signal to the corresponding pixel unit1. That is, in the display panel, it is required to provide the driving signal to the pixel driving chip2, so that the pixel driving chip2transmits the driving signal to the corresponding pixel unit1, and the at least two sub-pixels10in the pixel unit1may obtain the respective driving signal, thereby implementing the driving process of the display panel.

It should be noted that, in the display panel in the related art, as shown inFIG.4, since each sub-pixel requires the driving signal corresponding to the sub-pixel in the process of implementing the display of the display panel, it is required to provide driving chips of the number corresponding to the number of the sub-pixels, and the sub-pixels are in one-to-one correspondence with the driving chips, so that each driving chip provides a driving signal to the corresponding sub-pixel to implement the display. However, the number of sub-pixels in the display panel is often large, which results in a large number of driving chips, making the fabrication of the display panel difficult, especially for a display panel having high resolution.

In the display panel of the embodiment, each of the pixel driving chips2which are in one-to-one correspondence with the pixel units1provides the driving signal to the at least two sub-pixels10in the corresponding pixel unit1, that is, one pixel driving chip2corresponds to at least two sub-pixels10. Compared with the display panel in the related art, the number of the pixel driving chips2of the display panel in the embodiment is not required to be the same as the number of the sub-pixels10, thereby greatly reducing the difficulty in fabricating the display panel.

It should be noted that, the display panel of the present embodiment may be applied to different types of display panels such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, and a rotational display panel, and is particularly suitable for the rotational display panel. The following description will be given by taking a case where the display panel of the present embodiment is a rotational display panel as an example.

Specifically, in some embodiments, the display panel of the present application further includes: a rotating shaft8. The rotating shaft8is parallel to the column direction of the pixel units1, and the display panel may rotate around an axis where the rotating shaft8is located to implement stereoscopic display.

As shown inFIG.1andFIG.2, that is, the rotational display device may rotate at a specific angular speed by taking a line which is parallel to the columns of the pixel units and passes through the rotational display screen as an axis, each rotation of a specific angle corresponds to one electronic frame, the rotational display device displays different images in different electronic frames, and a cylindrical display space is formed in a very short time, so as to implement stereoscopic display in combination with principle of persistence of vision of human eyes.

In some embodiments, each pixel unit1includes three sub-pixels10.

The plurality of sub-pixels10are also arranged in an array. Each sub-pixel10may display a specific color, and each pixel unit1generates colored light by adjusting the brightness of the sub-pixel10, so as to implement color display of the display panel, thereby improving user experience.

Specifically, as shown inFIGS.4and5, the three sub-pixels10in each pixel unit1are a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, respectively.

It should be noted herein that the color of each sub-pixel10in the embodiment of the present disclosure may be determined according to the color of the light emitting device in the sub-pixel10. For example, if the light emitted by the light emitting device in the sub-pixel10is red light, the sub-pixel10is referred to as a red sub-pixel R. Of course, if the colors of light emitted by the light emitting devices in the display substrate are the same, for example, the light emitted by each light emitting device is white light, the colors of the sub-pixels are determined based on the colors of the color filters in the color filter substrate opposite to the display panel. For example, if the color of the color filter in the color filter substrate corresponding to a certain sub-pixel10is red, the sub-pixel10is referred to as a red sub-pixel R. As shown inFIGS.5to7, the sub-pixels10in the same row have the same color, and every three adjacent sub-pixels10in the column direction form a pixel unit1, and the three sub-pixels10in each pixel unit are respectively a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B.

In some embodiments, the sub-pixels10are micro LEDs.

That is to say, each pixel unit1includes three micro LEDs. Compared with the LED in the related art, the volume of micro LED is smaller, which may effectively reduce the density of the display units, further facilitates the formation of the display panel of high resolution, greatly reduce the graininess presented on the display screen, and further improve user experience.

In some embodiments, as shown inFIG.7, the display panel of the present disclosure further includes: a plurality of gate lines3, a plurality of data lines4, and a control component5. A row of pixel driving chips2corresponds to one gate line3; a column of pixel driving chips2corresponds to at least one data line4; and the control component5is coupled to the pixel driving chips2through the gate lines3and the data lines4, and is configured to provide driving signals to the pixel driving chips2through the gate lines3and the data lines4.

The gate lines3intersect with the data lines4, and the pixel driving chip2and the pixel unit1are defined at the intersection position. The pixel driving chips2in the same row are coupled to the same gate line3, and the pixel driving chips2in the same column are coupled to at least one data line4. Specifically, as shown inFIG.7, the data line4coupled to the first column of pixel driving chips2is referred to as Data1, the data line4coupled to the second column of pixel driving chips2is referred to as Data2, and so on. Similarly, the gate line3coupled to the first row of pixel driving chips2is referred to as Line1, the gate line3coupled to the second row of pixel driving chips2is referred to as Line2, and so on.

The control component5may provide the driving signals to the pixel driving chips2through the gate lines3and the data lines4, such that the pixel driving chips2write the driving signals into the respective pixel units1to implement display of the display panel.

In some embodiments, each pixel driving chip2has code information (or a code number). The control component5includes: a selection subcomponent configured to select a specific pixel driving chip2according to the code information of the pixel driving chips2, so that the control component5provides the driving signal to the specific pixel driving chip2. The pixel unit1corresponding to the specific pixel driving chip2is the pixel unit1that requires the driving signal.

That is to say, the pixel driving chip2has coding and decoding functions of the chip, thereby implementing coding of each pixel unit1. Meanwhile, after each pixel unit1has been encoded, the selection subcomponent of the control component5may select the specific pixel unit1corresponding to the specific pixel driving chip2according to the code information of each pixel unit1, and provide the driving signal to the specific pixel unit1through the specific pixel driving chip2. Specifically, the control component5may store display information of the pixel units1in the n-th frame in advance, so that the frame difference method can be performed in the (n+1)-th frame, that is, the specific pixel unit1in the (n+1)-th frame may be obtained according to the display states of the pixel units1in the n-th frame.

It should be noted that, the specific pixel unit1is a pixel unit1whose display content in the current electronic frame is different from that in the previous electronic frame, that is, to implement the display of the current electronic frame, it is only required to provide the selected specific pixel unit with the driving signal in the current electronic frame.

In the display panel in the related art, in the process of implementing display of the display panel, signals are input to all display units in each electronic frame to implement display. Therefore, a larger transmission bandwidth is required in the driving process of the display panel, in order to improve the display effect of the display panel.

In the display panel of the embodiment, firstly, the pixel units1that have been encoded are decoded, then, specific pixel units1are selected from the pixel units1, and the driving of the current electronic frame can be implemented only by providing the driving signals to the specific pixel units1through the specific pixel driving chips2, thereby implementing the display of the electronic frame. Compared with the display panel in the related art, the display panel of the embodiment has the advantages that the data transmitted in the driving process can be greatly reduced, only effective data can be transmitted, the requirement of the display panel on transmission bandwidth can be greatly lowered, and the display effect of the display panel can be greatly improved.

In some embodiments, the display panel of the present application further includes: an analog switch component6coupled between the control component5and the gate lines3, and the analog switch component6is configured to provide a switch signal to the gate line3in response to a signal of the control component5.

That is, the analog switch component6outputs the switch signal to each gate line3by receiving a signal output from the control component5. It should be noted that the switch signal is a signal for controlling whether each pixel driving chip2is electrically connected to the corresponding data line4, so as to control whether the data line4may provide a display signal to the corresponding pixel driving chip2. Specifically, in each electronic frame, an ON signal is sequentially provided to the respective gate lines3staring from the first gate line3, so that respective rows of pixel driving chips2sequentially electrically connect with the corresponding data lines4, and the data lines4provide display signals to the pixel driving chips2according to the timing sequence of the ON signals, so as to implement the display of the electronic frame.

In some embodiments, the display panel of the present application further includes: a power supply component7coupled to the control component5and the analog switch component6, respectively, and configured to provide power signals to the control component5and the analog switch component6.

The power supply component7mainly supplies power to the control component5and the analog switch component6to ensure the normal operation of the control component5and the analog switch component6, so as to ensure the normal operation during the driving process of the display panel.

In some embodiments, the plurality of pixel driving chips2include at least two portions having the same number of rows, the number of signal output lines61of the analog switch component6is the same as the number of gate lines3corresponding to any portion of the pixel driving chips2, and the gate lines3corresponding to a plurality of rows of pixel driving chips2in any portion of the pixel driving chips2are in one-to-one correspondence with the signal output lines.

That is, the number of the gate lines3is the same as that of the rows of any portion of the pixel driving chips2, the plurality of rows of pixel driving chips2in any portion of the pixel driving chips2are in one-to-one correspondence with the gate lines3, and the portions of the pixel driving chips2are the same in the number of the pixel driving chips2. In any portion of the pixel driving chips2, the plurality of rows of pixel driving chips2are in one-to-one correspondence the gate lines3, that is, each gate line3may be coupled to one row of pixel driving chips2in any portion of the pixel driving chips2, and one row of pixel driving chips2in one portion of the pixel driving chips2are coupled to the same gate line3as one row of pixel driving chips2in another portion of the pixel driving chips2.

Thus, in the scanning process of the gate lines3, the portions of the pixel driving chips2may be driven simultaneously to reduce the time required for driving each electronic frame, thereby increasing the electronic frame frequency of the display panel to improve the display effect.

In some embodiments, a plurality of columns of pixel driving chips2are in one-to-one correspondence with the data lines4in each portion of the pixel driving chips2, and the pixel driving chips2in different portions of the pixel driving chips2are coupled to different data lines4.

In order to more accurately select the specific pixel driving chip2, the pixel driving chips2belonging to different portions are coupled to different data lines4even though they are positioned in the same column.

It should be noted that the analog switch component6may simultaneously input the switch signal to two rows of pixel driving chips2located at different portions, so as to ensure the smooth driving process of the display panel.

Specifically, as shown inFIG.7, the plurality of pixel driving chips2are divided into a first portion a and a second portion b having the same number of rows, and the gate line corresponding to the n-th row of pixel driving chips2in the first portion a and the gate line corresponding to the n-th row of pixel driving chips2in the second portion b are coupled to the same signal output line61.

That is, the number of rows of the pixel driving chips2in the first portion a and the number of rows of the pixel driving chips2in the second portion b are the same, and the first row of pixel driving chips2in the first portion a and the first row of pixel driving chips2in the second portion b are both coupled to the first gate line3, that is, the first gate line3may simultaneously provide the switch signal to the first row of pixel driving chips2in the first portion a and the first row of pixel driving chips2in the second portion b. The second row of pixel driving chips2in the first portion a and the second row of pixel driving chips2in the second portion b are both coupled to the second gate line3, that is, the second gate line3may simultaneously provide the switch signal to the second row of pixel driving chips2in the first portion a and the second row of pixel driving chips2in the second portion b, and so on.

It should be noted that, in the display panel in the related art, respective rows of pixel units are coupled to different gate lines, so in each frame, if the driving time of each row is a, and there are 2n rows of pixel units1in total, a total time of 2na is required to complete the driving of each frame.

However in the display panel in this embodiment, if there are n rows of pixel driving chips2in each portion, there are two portions (2n rows of pixel driving chips2in total), and the time for scanning each row of pixel driving chips2is a, the driving time of each electronic frame is na since one gate line3may drive two rows of pixel driving chips2at the same time. It can be seen that, the connection structure of the gate lines3of the embodiment can greatly reduce the driving time of each electronic frame, thereby improving the electronic frame frequency of the display panel and further improving the display effect.

Specifically, as shown inFIG.7, for the structure of the display panel of the above embodiment, the display panel has 200 data lines4. 200 pins (Pin) of the control component5(FPGA) are coupled to the data lines4, that is, in the control component5(FPGA), 200 pins are used for transmitting display signals. The display panel has 100 gate lines3, and 100 pins (Pin) of the analog switch component6are coupled to the gate lines3, that is, 100 pins (namely Vcc1-Vcc100) of the analog switch component6are used for transmitting switch signals.

Specifically, the control component5(FPGA) encodes each pixel driving chip2(Pixel IC) as follows: since each data line4is coupled to 100 pixel driving chips2, the code numbers (ID) transmitted by all the data lines4are 1 to 100. The final encoding result is: pixel points of the pixel driving chips2in the 1strow (Line1) and the pixel driving chips2in the 101throw (Line101) are all encoded to be ID1, pixel points of the pixel driving chips2in the 2ndrow (Line2) and the pixel driving chips2in the 102throw (Line102) are all encoded to be ID2, and so on, pixel points of the pixel driving chips2in the 100throw (Line100) and the pixel driving chips2in the 200throw (Line200) are all encoded to be ID100.

After the initialization coding is completed, a turned-on process of the pixel units1is performed. In the turned-on process, the data format of the display information output by each data line4is: code number+grayscale data of the sub-pixel (Chip ID+RGB). When the gate lines3(Vcc1-Vcc100) are sequentially enabled, the pixel driving chips2(Pixel IC) decode the code numbers (Chip ID) of the corresponding pixel driving chips2, and only when the decoding result of the pixel driving chip2matches the initialization code number, the pixel driving chip2receives the data of the set of display information and generates a pulse width modulation signal (PWM), thereby turning on the pixel unit1.

For example, if the 30thand 50thpixel units1corresponding to the first data line4(Data1) are to be turned on, the display information output by the first data line4is: ID30+RGB30and ID50+RGB50; the gate lines3(Vcc1-Vcc100) are sequentially enabled, and only when the gate lines Vcc30and Vcc50are enabled, the decoding result matches with the initialization code (ID), and the RGB30and RGB50are respectively received by the 30thand 50thpixel driving chips2, so the 30thand 50thpixel units1are turned on.

For another example, the display data to be transmitted when one pixel unit1is turned on is code number+grayscale data of the sub-pixel (Chip ID+RGB), which occupies 8 bit+16 bit×3=56 bit. If the refresh rate of the display panel is 21600 Hz and the transmission bandwidth of the data line4is 16 Mbps, among 100 pixel units1coupled to one data line4, at most 13 pixel units may be turned on in one electronic frame of image. The calculation process is shown in the following formula: 16 Mbps/21600 Hz/56 bit=13.23≈13. This is sufficient for the display panel of the present embodiment. In addition, by research, the transmission bandwidth of the data line4can reach 32 Mbps, and thus, the display panel of the embodiment has a large improvement space in the display effect.

It should be noted that the display panel of the present embodiment can also be divided into three portions, four portions, or the like, which are not limited to the above-mentioned cases and can be determined according to the actual requirements of the display panel.

In a second aspect, as shown inFIG.8, the embodiments provide a driving method of a display panel, which is based on the display panel described above, and the driving method includes providing, by the pixel driving chip2, a driving signal to the corresponding pixel unit1to implement the display of the display panel.

The pixel units1are structures configured to emit display light in a display panel, and each pixel unit1corresponds to one pixel driving chip2. The pixel driving chip2is a structure configured to provide a driving signal to the pixel unit1in the display panel such that the pixel unit1emits display light. Each pixel unit1includes at least two sub-pixels10, and it should be noted that, during the display process of the display panel, each sub-pixel10requires a driving signal corresponding to the sub-pixel10.

Since the pixel units1are in one-to-one correspondence with the pixel driving chips2, the pixel driving chip2is only required to provide the driving signal to the corresponding pixel unit1, that is, in the display panel, it is only required to provide the driving signals to the pixel driving chips2, so that the pixel driving chips2transmit the driving signals to the corresponding pixel units1, and the driving process of the display panel can be implemented.

It should be noted that, in the display panel in the related art, since each sub-pixel10requires a driving signal corresponding thereto in the display process of the display panel, it is required to provide driving chips of the number corresponding to the number of the sub-pixels10, and the sub-pixels10are in one-to-one correspondence with the driving chips, so that each driving chip provides a driving signal to the sub-pixel10corresponding thereto to implement display. However, the number of sub-pixels10in a display panel is often large, which results in a large number of driving chips, thus making the fabrication of the display panel difficult, especially for the display panel having high resolution.

In the driving method of the display panel of the embodiment, each of the pixel driving chips2in one-to-one correspondence with the pixel units provides the driving signal to the at least two sub-pixels10in the pixel unit1, that is, one pixel driving chip2corresponds to at least two sub-pixels10. Compared with the display panel in the related art, the number of the pixel driving chips2of the display panel in the embodiment is not required to be the same as the number of the sub-pixels10, thereby greatly reducing the difficulty in fabricating the display panel.

Specifically, providing the driving signal to the corresponding pixel unit1by the pixel driving chip2to implement the display of the display panel at least includes: Step S11to Step S15.

In Step S11, the plurality of pixel driving chips2are encoded such that each pixel driving chip2has a respective code number.

It should be noted that, the plurality of pixel driving chips2may be divided by row into a first portion a and a second portion b with the same number of rows, and the n-th row of pixel driving chips2in the first portion a and the n-th row of pixel driving chips2in the second portion b are coupled to the same gate line3.

Specific encoding rules for the structure of the display panel are as follows. If each data line4is coupled to 100 pixel driving chips2, the code numbers (ID) transmitted by all the data lines4are: 1 to 100. The plurality of gate lines3are Vcc1to Vcc100. The final encoding result is: pixel points of the pixel driving chips2in the 1strow (Line1) and the pixel driving chips2in the 101throw (Line101) are all encoded to be ID1, pixel points of the pixel driving chips2in the 2ndrow (Line2) and the pixel driving chips2in the 102throw (Line102) are all encoded to be ID2, and so on, pixel points of the pixel driving chips2in the 100throw (Line100) and the pixel driving chips2in the 200throw (Line200) are all encoded to be ID100.

In Step S12, the display information of the pixel units1in the n-th frame is acquired.

That is, the control component5of the display panel may store the display information of the pixel units1in the n-th frame in advance. The display information includes grayscale data of each sub-pixel10in the pixel unit1.

In Step S13, a specific pixel unit1is obtained according to the display information of the pixel units1in the n-th frame, where the specific pixel unit1is the pixel unit1that requires the driving signal in the (n+1)-th frame, and the pixel driving chip2corresponding to the specific pixel unit1is the specific pixel driving chip2.

Specifically, the specific pixel unit1is obtained according to the display states of the pixel units1in the n-th frame by using a frame difference method.

That is, by comparing the display information of the pixel units1in the (n+1)-th frame with the display information of the pixel units1in the n-th frame, the pixel unit1in which the display data is changed in the (n+1)-th frame relative to that in the n-th frame is selected as the specific pixel unit1.

Specifically, the selection of the specific pixel driving chip2follows the following table (shown are different display states of the pixel units1(five kinds of pixel units1numbered by the serial numbers) in the n-th frame and the (n+1)-th frame respectively, and “no data transmission is required” indicates that the corresponding pixel unit1in the (n+1)-th frame is not a specific pixel unit, and the rest of the pixel units1are specific pixel units).

In Step S14, the code information of the specific pixel driving chip2is acquired.

In Step S15, the driving signal is input to the specific pixel drive chip2based on the code information.

In this case, after the initialization coding is completed, the turned-on process of the pixel units1is performed. In the subsequent turned-on process, the data format of the display information transmitted and output by each data line4is: code number+grayscale data of the sub-pixel10(Chip ID+RGB). When the gate lines3(Vcc1-Vcc100) are sequentially enabled, the pixel driving chips2(Pixel IC) decode the code numbers (Chip ID) of the corresponding pixel driving chips2, and only when the decoding result of the pixel driving chip2matches the initialization code number, the pixel driving chip2receives the data of the set of display information and generates a pulse width modulation signal (PWM), thereby turning on the pixel unit1.

For example, if the 30thand 50thpixel units1corresponding to the first data line4(Data1) are to be turned on, the display information output by the first data line4is: ID30+RGB30and ID50+RGB50; the gate lines3(Vcc1-Vcc100) are sequentially enabled, and only when the gate lines Vcc30and Vcc50are enabled, the decoding result matches with the initialization code (ID), and the RGB30and RGB50are respectively received by the 30thand 50thpixel driving chips2, so the 30thand 50thpixel units1are turned on.

In the driving method of the display panel of the embodiment, firstly, the pixel units1that have been encoded are decoded, then, specific pixel units1are selected from the pixel units1, and the driving of the electronic frame can be implemented only by providing the driving signals to the specific pixel units1through the specific pixel driving chips2, so as to implement the display of the electronic frame. Compared with the display panel in the related art, the display panel of the embodiment has the advantages that the data transmitted in the driving process can be greatly reduced in the driving process, only effective data can be transmitted, the requirement of the display panel on transmission bandwidth can be greatly reduced, and the display effect of the display panel can be greatly improved.

In a third aspect, the embodiments provide a display device, which includes the display panel described above, and the display device is a stereoscopic rotational display device.

Specifically, the display device may include a plurality of pixel units arranged in an array, can rotate at a specific angular speed by taking a line which is parallel to the columns of the pixel units and passes through the rotational display screen as a rotating shaft. Each rotation of a specific angle corresponds to an electronic frame, the rotational display device displays different images in different electronic frames, and a cylindrical display space is formed in a very short time, so as to implement stereoscopic display in combination with principle of persistence of vision of human eyes.

In the display device of the embodiment, each of the pixel driving chips2in one-to-one correspondence with the pixel units1provides the driving signal to at least two sub-pixels10in the corresponding pixel unit1, that is, one pixel driving chip2corresponds to at least two sub-pixels10. Compared with the display panel in the related art, the number of the pixel driving chips2of the display panel in the embodiment is not required to be the same as the number of the sub-pixels10, thereby greatly reducing the difficulty in fabricating the display panel.

In addition, in the display device of this embodiment, firstly, the pixel units1that have been encoded are decoded, then, specific pixel units1are selected from the pixel units1, and the driving of the electronic frame can be implemented only by providing the driving signals to the specific pixel units1through the specific pixel driving chips2, so as to implement the display of the electronic frame. Compared with the display panel in the related art, the display panel of the embodiment has the advantages that the data transmitted in the driving process can be greatly reduced in the driving process, only effective data can be transmitted, the requirement of the display panel on transmission bandwidth can be greatly reduced, and the display effect of the display panel can be greatly improved.
