     DETAILED DESCRIPTION OF EMBODIMENTS 
     Embodiments of the present disclosure provide an electronic device and a display apparatus thereof. The electronic device may include a display apparatus and a camera. A lens of the camera and the display apparatus are correspondingly disposed, that is, the camera acquires external light signals passing through the display apparatus for imaging. It can be understood that light transmittance of a conventional display apparatus is relatively low, and imaging effect of the camera through the display apparatus is not good. For this reason, an embodiment of the present disclosure may configure a display apparatus in a manner of different regions. 
     For example, light transmittance of a portion of the display apparatus corresponding to the camera is configured to be greater than light transmittance of other positions of the display apparatus, so that imaging effect of the camera can be improved. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in embodiments of the present disclosure. 
     An electronic device provided in an embodiment of the present disclosure may be a mobile terminal device such as a mobile phone and a tablet computer, and may also be a game device, an augmented reality (AR) device, a virtual reality (VR) device, an in-vehicle computer, a notebook computer, a data storage apparatus, an audio playback apparatus, a video playback apparatus, a wearable device, and other devices with a display apparatus, wherein the wearable device can be a smart bracelet, smart glasses, and the like. 
     Please refer to  FIG. 1 , which is a schematic diagram of a first structure of an electronic device provided by an embodiment of the present disclosure.  FIG. 1  shows an example in which the electronic device is a mobile phone, wherein the display apparatus  20  includes a first display region  220  and a second display region  240 , and the light transmittance of the second display region  240  is greater than that of the first display region  220 . A camera  60  is provided in the electronic device  10 , a lens of the camera  60  is disposed toward the second display region  240 , wherein the camera  60  is used to acquire external light signals passing through the second display region  240  for imaging. It can also be understood that the camera  60  is disposed under the second display region  240  of the display apparatus  20 , wherein the camera  60  is used to acquire the external light signals passing through the second display region  240  of the display apparatus  20  and to image according to the acquired external light signals. A display region of the display apparatus  20  is complete, and a screen ratio of the display apparatus  20  is increased. The camera  60  may be used as a front camera of the electronic device, and the camera  60  may be used to acquire images such as self-portraits of a user through the second display region  240  of the display apparatus  20 . 
     For a more comprehensive understanding of the display apparatus of embodiments of the present disclosure. The display apparatus will be described in detail below. 
     Please refer to  FIG. 2 , which is a schematic diagram of a first structure of a display apparatus according to an embodiment of the present disclosure. The display apparatus  20  in the embodiment of the present disclosure may include a first display region  220  and a second display region  240  adjacent to each other. Both the first display region  220  and the second display region  240  can be used to display text or images, and the first display region  220  and the second display region  240  can jointly display the same image. 
     For example, the first display region  220  displays a part of a preset image, and the second display region  240  displays the remaining part of the preset image. The first display region  220  and the second display region  240  may also display different images. 
     For example, the first display region  220  displays a preset image, and the second display region  240  displays a taskbar image. Both the first display region  220  and the second display region  240  can display contents, wherein display regions are complete, a screen ratio of the display apparatus  20  is high. The first display region  220  can surround the second display region  240 , and a periphery of the second display region  240  can be both adjacent to the first display region  220 , that is, the second display region  240  is located in a middle portion of the first display region  220 . The first display region  220  can also partially surround the second display region  240 , and a part of edges of the second display region  240  is adjacent to the first display region  220 . 
     For example, the second display region  240  is located at a corner of the display apparatus  20  or at the middle portion of a top portion of the device  20 . 
     Please refer to  FIGS. 3 to 5 ,  FIG. 3  is a schematic diagram of a first partial structure of a display apparatus provided by an embodiment of the present disclosure,  FIG. 4  is an enlarged schematic diagram of a Z 1  portion of the display apparatus shown in  FIG. 3 , and  FIG. 5  is a schematic structural diagram of a first-pixel set and a first driving circuit of a display apparatus according to an embodiment of the present disclosure. The first display region  220  includes a plurality of first pixels  226  arranged in an array manner, and the first display region  220  may further include a plurality of sixth driving units, wherein one of the sixth driving units drives one of the first pixels  226 . 
     For example, the first display region  220  includes M first pixels  226  and M sixth driving units. 
     The second display region  240  includes a plurality of regular-shape first-pixel sets  2422 , each of the first-pixel sets  2422  includes a plurality of second pixels  246 , wherein all of the second pixels  246  in each of the first-pixel sets  2422  share one first driving unit  248 . The plurality of second pixels in each of the first-pixel sets  2422  may be connected in parallel, so as to share one first driving unit. The plurality of second pixels in each of the first-pixel sets  2422  can also be connected in series, so as to share one first driving unit. It should be noted that a parallel connection will not change a driving voltage of the first driving unit, and a number of second pixels in each of the first-pixel sets formed in a parallel connection manner may be more than that in each of the first-pixel sets formed in a serial connection manner. A second-pixel set has the same connection as the first-pixel set. 
     The second display region  240  includes a plurality of regular-shape first-pixel sets  2422 , each of the first-pixel sets  2422  includes a plurality of second pixels  246  connected in parallel, wherein all of the second pixels  246  in each of the first-pixel sets  2422  share one driving unit  248 . 
     Each of the first driving units  248  is electrically connected to one of the first-pixel sets  2422 , and each of the first driving units  248  is used to drive all of the second pixels  246  in one of the first-pixel sets  2422  that is electrically connected to the first driving unit. The plurality of second pixels  246  within the second display region  240  share one of the first driving units  248 , so that a number of the first driving units  248  for driving the second display region  240  may be less than a number of the first pixels  226 . 
     For example, the second display region  240  includes N first-pixel sets  2422 , each of the first-pixel sets  2422  includes four second pixels  246 , one of the first-pixel sets  2422  corresponds to one first driving units  248 , and the second display region  240  includes 4N second pixels  246  and N first driving units  248 . Compared with the first display region  220 , a ratio of the first driving units  248  to the second pixels  246  disposed within the second display region  240  is smaller, and distribution density of the first driving units  248  within the second display region  240  is less than distribution density of sixth driving units  228  within the first display region  220 , and each of the first driving units  248  and each of the sixth driving units both include opaque elements (such as thin-film transistors, TFT), which can make the opaque elements be included within the second display region  240  less than that within the first display region  220 , so that light transmittance of the second display region  240  can be much greater than that of the first display region  220 . 
     A shape and dimension of the second display region  240  can be set according to the camera, and an edge region between the second display region  240  and the first display region  220  needs special processing. To improve the display effect of the display apparatus, the smaller the dimension of the second display region  240 , the better. The second display region  240  needs to meet requirements of the camera, so that the second display region  240  needs to correspond to a lens configuration of the camera. 
     For example, the second display region  240  may be circular, and the dimension of the second display region  240  is slightly greater than the lens of the camera and completely covers the lens of the camera. It can also be understood that an orthographic projection of the lens on the display apparatus is within the second display region  240 . A position where the circular second display region  240  is adjacent to the first display region  220  includes an arc structure, which is not conducive to dividing the plurality of second pixels within the second display region  240  into the first-pixel sets. The second display region  240  may also be shaped as a regular shape such as an ellipse, a semi-circle, a rounded rectangle, and the like, in which an edge includes an arc-shaped structure. The second display region  240  may also be shaped as a regular shape such as a regular polygon, such as a regular hexagon, in which an edge includes an arc structure similar to a bending structure. Certainly, the second display region may also be shaped as an irregular shape with an edge including an arc structure. 
     Each of the regular-shape first-pixel sets  2422  within the second display region  240  includes a plurality of second pixels  246 , wherein the plurality of second pixels  246  within each of the first-pixel sets can be arranged in an array manner. 
     For example, the second pixels  246  within each of the first-pixel sets are arranged in two rows, with two of the second pixels  246  in each row. All of the plurality of second pixels  246  within the second display region  240  can be divided into different pixel sets, but the dimension and shape of the second display region  240  need to be configured according to the camera. The edge of the second display region  240  adjacent to the first display region  220  includes an arc structure. A part of the second pixels  246  located at positions adjacent to the second display region  240  and the first display region  220  may not be within the first-pixel set arranged in a complete array. If the part of the second pixels  246  is not displayed, then there are black dots (pixels) that are not displayed between the second display region  240  and the first display region  220 , wherein a transition between the second display region  240  and the first display region  220  is uneven. Therefore, to make the transition between the second display region  240  and the first display region  220  be even, it is also necessary to drive and display the part of the second pixels  246 . 
     Specifically, the second display region  240  may include a plurality of regular-shape first-pixel sets  2422  and at least one second-pixel set  2424  that is conformal to an edge of the second display region  240 . The plurality of second pixels  246  within each of the first-pixel sets  2422  are arranged in a regular shape, such as 2 rows and 2 columns, 3 rows and 3 columns, 2 rows and 3 columns, 3 rows and 2 columns, 4 rows and 4 columns, or the like. A number of second pixels  246  involved in the second-pixel set  2424  conformal to the edge of the second display region  240  is less than that in each of the first-pixel sets  2422 . It can also be understood that the plurality of second pixels  246  within the second display region  240  are divided into the plurality of first-pixel sets  2422  as possible first, and the remaining ones are not enough to be divided into one regular-shape first-pixel set  2422 , wherein the remaining second pixels  246  are adjacent to an edge of the second display region  240 . The remaining second pixels  246  are still divided according to the original division rule and abandoned beyond the second display region  240 , only the remaining parts are connected in parallel to form the second-pixel set  2424 . The second-pixel set  2424  is at least one set of the second pixels  246  located at edges of the second display region  240 , not within the first-pixel set  2422 . 
     For example, the first-pixel set  2422  is arranged in 2 rows and 2 columns. In a k-th row and a (k+1)th row, the edge of the second display region  240  has one of the second pixels  246  located at the i-th column in the k-th row and two of the second pixels  246  located at the i-th and (i+1) columns in the (k+1)th row. This three of the second pixels  246  are connected in parallel to form an second-pixel set  2424  conformal to an edge of the second display region  240 , wherein a number of the second pixels  246  in each row is different. It should be noted that the number and arrangement of the second pixels  246  in the second-pixel set  2424  are determined according to the edge of the second display region, and the number and arrangement of the second pixels  246  included in different second-pixel sets  2424  may also be different. The second-pixel set  2424  may include only one of the pixels  246  or may include a plurality of the second pixels  246 . It should be noted that a first number may be a fixed value, such as 9 or 6, and a second number may be a value less than the first number and not fixed. The second-pixel set conformal to the edge of the second display region includes irregular edges, and the irregular edge of at least one second-pixel set is conformal to the arc structure of the second display region. It can also be understood that the second-pixel set conformal to the edge of the second display region includes an arc-shaped structure with irregular edges forming the second display region. 
     If the second pixels  246  within the second display region  240  have the same physical structure as the first pixels within the first display region  220 , a smooth transition can be formed through the irregular transition of the second-pixel set  2424 . In particular, when the edge of the second display region  240  adjacent to the first display region  220  includes an arc structure, an abrupt feeling of a linear transition and a destructive feeling of a jagged display can be avoided. A corresponding display smoothing algorithm may also be applied for the second-pixel set  2424 , and display smoothing transition processing is performed on the pixels  246  of the second-pixel set  2424  to achieve a smooth transition. In addition, an algorithm applied for the first display region  220  may correspond to an algorithm applied for a part of the second pixels  246  adjacent to the first display region  220 , and display smoothing transition processing is performed on a portion of the first display region  220  adjacent to the second display region  240  to achieve a smooth transition. The physical structure of each of the second pixels  246  within the second display region  240  is the same as that of each of the first pixels of the first display region  220 , which can be understood as the dimension, distribution density, and arrangement of the first pixels of the first display region  220  are the same as that of the second pixels within the second display region  240 . 
     It should be noted that the larger the volume of the pixel to be driven is, the larger the required driving capability is. Furthermore, because a thickness of each of the pixels is fixed in a display apparatus, the larger the area of the pixel is, the larger the required driving capability is. The number of the second pixels  246  included in each of the regular-shape first-pixel sets  2422  is fixed, and the corresponding driving capability thereof is also fixed. The number of the second pixels  246  included in each of the second-pixel sets  2424  conformal to the edge of the second display region  240  is not fixed, e.g., the number of the second pixels included in the second-pixel set  2424  may be 1, 2, 3, 4, and so on. Different numbers of pixels  246  correspond to different driving capabilities. Driving circuits of second driving units for driving all of the second-pixel sets  2424  may be the same. 
     For example, the second driving units for driving all of the second-pixel sets  2424  may be one type of 7T1C, 5T1C, or 2T1C. The driving circuits of the second driving units are the same, but the driving capability is indeed different, which can be realized by a dimension of a single element (such as one or more thin-film transistors) in the second driving unit. The larger the dimension of the thin-film transistor, the greater the driving capability thereof. Namely, the dimension of the thin-film transistor in the second driving unit electrically connected to the second-pixel set  2424  is positively correlated to the number of the second pixels  246  in the second-pixel set  2424 . It can also be understood that the greater the number of the second pixels  246  in the second-pixel set  2424 , the larger the dimension of the one or more thin-film transistors of the second driving unit electrically connected to the second pixels  246 . 
     It should be noted that the first driving unit  248  for driving the first-pixel set  2422  may have the same driving circuit as the second driving unit for driving the second-pixel set  2424 . The first driving unit  248  driving the first-pixel set  2422  may also have a different driving circuit from the second driving unit driving the second-pixel set  2424 . 
     For example, the first driving unit for driving the first-pixel set  2422  is 5T1C, and the second driving unit for driving the second-pixel set  2424  is 2T1C. 
     To further improve light transmittance of the second display region, the first driving unit and the second driving unit may be disposed in other regions than the second display region. Specifically, please refer to  FIGS. 6 and 7 ,  FIG. 6  is a schematic diagram of a second structure of a display apparatus provided by an embodiment of the present disclosure, and  FIG. 7  is a schematic diagram of a second partial structure of a display apparatus according to an embodiment of the present disclosure. The first display region  220  may include a third display region  260 . The third display region  260  is adjacent to the second display region  240 . It can also be understood that a part of the first display region  220  adjacent to the second display region  240  is configured as the third display region  260 . Specifically, the third display region  260  may completely surround the second display region  240 . Alternatively, the third display region  260  may partially surround the second display region  240 . 
     For example, the third display region  260  is disposed on two sides of the second display region  240 . 
     Please refer to  FIGS. 8 and 9 ,  FIG. 8  is an enlarged schematic view of a Z 2  portion of the display apparatus shown in  FIG. 7 , and  FIG. 9  is a schematic structural diagram of pixels and driving units within a third display region of a display apparatus according to an embodiment of the present disclosure. The plurality of first driving units  248  and second driving units for driving the second pixels  246  within the second display region  240  may be disposed within the third display region  260  in addition to the second display region  240 . The camera does not need to obtain external light signals through the third display region  260 . A plurality of first driving units  248  and second driving units are arranged within the third display region  260 , and the first driving units  248  and second driving units are not arranged within the second display region  240 . The first driving units  248  and second driving units that are opaque are not arranged within the second display region  240 , so that the light transmittance of the second display region  240  can be much greater than that of the first display region  220  and the third display region  260 . Meanwhile, other problems caused by the first driving units  248  and second driving units are reduced, such as a diffraction problem caused by the first driving units  248  periodically arranged on the imaging of the camera, and reflection and refraction problems caused by the first driving units  248  and second driving units on the imaging of the camera. 
     It can be understood that the greater the distribution density of the first pixels  246  within the first display region  220  of the display apparatus  20 , the more the pixels  246  within a unit area, the higher the resolution, and the better the display effect provided. Considering the production process of the display apparatus  20 , the dimension of each of the first pixels  226  within the first display region  220  corresponds to that of each of the sixth driving units  228  for driving the first pixels  226 . The plurality of sixth driving units  228  also require a plurality of signal lines to be connected to the driving chips of the display apparatus  20 . Each of the driving chip controls each sixth driving unit  228  via the plurality of signal lines, wherein the plurality of signal lines are arranged between the plurality of sixth driving units.  228 , and there is spacing between the first pixels  226 , and the spacing are configured to correspond to the signal lines. Each of the signal lines has a certain line width, which needs to meet impedance requirements and product technology. 
     For example, density of the first pixels within the first display region  220  can reach more than 400 ppi, the dimension of each of the first pixels  226  and that of each of the sixth driving units  228  within the first display region  220  are approximately equal. Each of the sixth driving unit  228  is correspondingly disposed under one of the first pixels  226 . The plurality of signal lines are arranged between the plurality of sixth driving units  228  and correspondingly arranged under the space between the first pixels  226 . The sixth driving units  228  and the signal lines connected to the sixth driving units are basically cover an entire space, and it is difficult to accommodate other components. The plurality of first pixels  226  within the third display region  260  are connected in parallel to form a plurality of third-pixel sets  2426 . Each of the third-pixel sets  2426  includes the pixels  246  connected in parallel with each other. All of the pixels  246  in each of the pixel sets  2426  are electrically connected to one of third driving units  268 . Each of third driving units  268  can drive all of the pixels  246  in one of the third-pixel sets  2426  electrically connected to the third driving unit. It should be noted that, in this embodiment, the sixth driving units drive the first pixels within the first display region except the third display region. 
     If each of the third driving units  268  and each of the sixth driving units  228  are the same driving circuit, the dimension of each of the third driving units  268  is equal to or slightly greater than the dimension of each of the sixth driving unit  228 , and line widths of the signal lines connecting to the third driving units  268  and connecting to the sixth driving units  228  are approximately equal, the first pixels within the third display region  260  are connected in parallel to form the third-pixel sets. In addition, each of the third-pixel sets  2426  only needs one of the third driving units  268  for driving. The dimension of each of the third driving units  268  is approximately equal to the dimension of one of the first pixels  226 . The plurality of pixels  246  of each of the third-pixel sets  2426  within the third display region  260  correspond to one third driving unit  268 . Therefore, a layer of the third display region  260  on which the third driving units  268  are disposed has an accommodating space, wherein the accommodating space can be used to accommodate the first driving units  248  and second driving units for driving the second pixels  246  within the second display region  240 . 
     When the first pixels  226  and the third driving units  268  are arranged within the third display region  260 , each of the third driving units  268  and one of the third-pixel sets  2426  electrically connected to the third driving unit are correspondingly disposed. 
     For example, each of the third driving units  268  is disposed under one of the third-pixel sets  2426  electrically connected to the third driving unit and at least partially opposite to one of the first pixels  226  in one of the third-pixel sets  2426 . When the first driving units  248  and/or the second driving units are disposed, one pixel  246  in each of the third-pixel sets  2426  and one of the third driving units  268  are correspondingly disposed, and another pixel  246  in each of the third-pixel sets  2426  and one of the first driving units  248  and/or second driving units are correspondingly disposed. It can also be understood that one of the third driving units  268  and at least one first driving unit  248  or second driving unit may be disposed under one of the third-pixel sets  2426 . A number of the first driving units  248  or the second driving units is set to be positively correlated with a number of the first pixels  226  in one of the third-pixel sets  2426 . Exemplarily, each of the third-pixel sets  2426  includes three first pixels connected in parallel with each other, and one of the third driving units  268  and two of the first driving units  248  may be disposed under one of the third-pixel sets  2426 . It should be noted that if the first driving units and the second driving units are relatively simple driving circuits (such as 2T1C), the dimensions of the first driving units and the second driving units are small, and one of the first pixels can correspond to two or more of the first driving units or second driving units. 
     The plurality of first driving units and second driving units may also be disposed within the second display region and the third display region as required. Exemplarily, a part of the plurality of first driving units and second driving units are disposed within the second display region, and a part of the plurality of first driving units and second driving units are arranged within the third display region. 
     For example, in order to facilitate the arrangement of the first driving units and the second driving units and simplify the connection of the first driving units and the second driving units to the second pixels within the second display region, a part of the first driving units and the second driving units are disposed at a perimeter of the second display region, and a part of the first driving units and the second driving units are arranged within the third display region. 
     The first driving units, the second driving unit, and the third driving units disposed within the third display region may also adopt another arrangement manner. Specifically, please refer to  FIGS. 10 and 11 ,  FIG. 10  is a schematic diagram of a third partial structure of a display apparatus provided by an embodiment of the present disclosure, and  FIG. 11  is an enlarged schematic view of an X portion of the display apparatus shown in  FIG. 10 . The plurality of third driving units  268  for driving the first pixels  226  within the third display region  260  may be centrally arranged, the plurality of third driving units  268  within the third display region  260  are centrally arranged at a position away from the second display region  24 , and the plurality of first driving units and the second driving units for driving the second pixels within the second display region may be centrally arranged at a position near the second display region  240 . The plurality of third driving units  268  disposed within the third display region  260  are centrally arranged between the plurality of first driving units  248  and the plurality of sixth driving units  228 . 
     The first driving units  248  and second driving units are located under the third-pixel sets within the third display region  260  adjacent to the second display region  240 , and the third driving units  268  are located under the third-pixel sets within the third display region  260  away from the second display region  240 . 
     For example, each of the third-pixel sets has 4 pixels in parallel, four of the first driving units  248  are correspondingly arranged under one of the third-pixel sets within the third display region  260  adjacent to the second display region  240 , and four of the third driving units  268  are correspondingly arranged under one of the third-pixel sets within the third display region  260  away from the second display region  240 . 
     Because the edge of the second display region adjacent to the third display region includes arc structures, in order to smoothly transition from the second display region to the first display region or the third display region, the second display region is provided with second-pixel sets conformal to the edge of the second display region, please specifically refer to the above description, which will not be repeated here. 
     In order to make that the third display region can also smoothly transition to the second display region, at least one irregular fourth-pixel set is also disposed at a position where the third display region is adjacent to the second display region. Please specifically refer to  FIGS. 12 and 13 ,  FIG. 12  is a schematic diagram of a fourth partial structure of a display apparatus provided by an embodiment of the present disclosure, and  FIG. 13  is an enlarged schematic view of a Z 3  portion of the display apparatus shown in  FIG. 12 . Fourth-pixel sets  2428  are adjacent to the second display region  240 ; all of the first pixels  226  in each fourth-pixel set  2428  are electrically connected to one fourth driving unit; each of the third-pixel sets  2426  includes a third number of the first pixels  226  connected in parallel with each other, and each of the third-pixel sets is a regular pixel set. The irregular fourth-pixel set  2428  includes a fourth number of the first pixels  226  connected in parallel with each other, wherein the fourth number is less than the third number. It should be noted that the third number may be a fixed value, such as 9 or 6, and the fourth number may be a non-fixed value less than the third number. 
     The third number of first pixels  226  in each of the regular third-pixel set  2426  are arranged in a regular shape, such as an arrangement of 2 rows and 2 columns, an arrangement of 3 rows and 3 columns, an arrangement of 2 rows and 3 columns, an arrangement of 3 rows and 2 columns, an arrangement of 4 rows and 4 columns, or the like. The number of the first pixels  226  included in the fourth-pixel set  2428  is less than that in the third-pixel set  2426 . It can also be understood that the plurality of first pixels  226  within the third display region  260  are first divided to form the plurality of third-pixel sets  2426 , and the remaining first pixels that are not enough to be divided to form a complete third-pixel set are divided to form at least one fourth-pixel set  2428 , and the remaining first pixels  226  are adjacent to the edge of the second display region  240 . The remaining first pixels  226  are still divided according to the original division rules, in which some are abandoned beyond the third display region  260 , only the remaining parts are connected in parallel to form the fourth-pixel set  2428 . The fourth-pixel set  2428  is a set of the first pixels  226  which locate at the edge of the third display region  260  and do not locate in the third-pixel set  2426 . 
     It should be noted that the number and arrangement of the first pixels  226  in the fourth-pixel set  2428  are determined according to the edge of the third display region, and the number and arrangement of the first pixels  226  included in different fourth-pixel sets  2428  may also be different. The fourth-pixel set  2428  may include only one first pixel  226  or may include a plurality of first pixels  226 . 
     Because the physical structures of the first pixel within the third display region  260  and the second pixels within the second display region  240  may be completely consistent, a smooth transition between the second-pixel sets  2426  within the second display region  240  and the fourth-pixel set  2428  within the third display region  260  can be formed. Especially, when the edge of the second display region  240  includes arc-shaped structures, the abrupt feeling of the straight-line transition and the destructive feeling of the jagged display can be avoided. Corresponding display smoothing algorithms may also be set for the second-pixel sets  2426  and the fourth-pixel set  2428 , and display smoothing transition processing is performed on the pixels  246  of the second-pixel sets  2426  and the fourth-pixel set  2428  to achieve a smooth transition. 
     The third number of the first pixels in the third-pixel set  2426  may be equal to the first number of the second pixels in the first-pixel set  2422 . The numbers of pixels in the first-pixel set  2422  and the third-pixel set  2426  are the same, and the first-pixel set  2422  and the third-pixel set  2426  adopt the same parallel mode, so that the parallel mode can be simplified. 
     The third number of the first pixels in the third-pixel set  2426  may also be less than the first number of the second pixels in the first-pixel set  2422 . The third display region  260  does not need to be used for the camera to obtain external light signals, the number of pixels  246  in the third-pixel set  2426  is less than that in the first-pixel set  2422 , and the display effect of the third display region  260  may be better than that of the second display region  240 , wherein an area of the first display region other than the third display region has the best display effect. By the transition from the third display region  260  to the second display region  240 , the sudden change of the display effect is reduced. 
     The third number of the first pixels  226  in the third-pixel set  2426  may also be greater than the first number of second pixels  246  in the first-pixel set  2422 . The third display region  260  does not need to be used for the camera to obtain external light signals. The number of first pixels  226  in the third-pixel set  2426  is greater than the number of second pixels in the first-pixel set  2422 , and the third display region  260  can be set smaller to reduce an area of an abnormal display region. 
     The third display region  260  may also not be provided with a set of pixels, that is, each of the first pixels within the third display region  260  is electrically connected to one of the third driving units, and each of the third driving units corresponds to one of the first pixels within the third display region, and at least one of the first pixels within the third display region also corresponds to the first driving unit or the second driving unit. In order to accommodate the first driving units and the second driving units within the third display region, the third driving unit within the third display region can use a relatively simple driving circuit, such as 5T1C, 2T1C, or other driving circuits. In this way, one layer on which the third display region is provided with the third driving units has accommodation spaces, wherein the accommodation spaces can be used to accommodate the first driving units and the second driving units. In order to conveniently dispose the first driving units and the second driving units within the third display region, the first driving unit and the second driving unit may also use relatively simple driving circuits, such as 5T1C, 2T1C, or other driving circuits  248  and second driving units. The first pixels within the first display region other than the third display region may adopt a driving circuit with a more complex and better effect than the third driving circuit, such as a 7T1C driving circuit and the like. In addition, in order to accommodate the first driving unit and the second driving unit in the third display region, the dimension of the first pixel in the third display region can also be made larger, and the dimension of the first pixel in the third display region is greater than the corresponding driving circuit, so, a plurality of first pixels in the third display region jointly accommodate a first driving unit. 
     For example, one of the first pixels within the third display region corresponds to one of the second driving units, meanwhile, one first driving unit or one second driving unit is accommodated between four first pixels. 
     It should be noted that the first driving unit may adopt a simpler driving circuit than that of the third driving unit, that is, a number of thin-film transistors involved in one first driving unit may be less than a number of thin-film transistors involved in one third driving unit. 
     For example, the first driving unit is 2T1C, and the third driving unit is 5T1C. For better light transmittance within the second display region, and for better disposing the first driving unit within the third display region, the first driving unit adopts the simplest driving circuit. In order to better accommodate the first driving units within the third display region and to ensure the display effect of the third display region, the third driving circuits adopt driving circuits with better effect than the first driving units and simpler than sixth driving circuits. In order to simplify the disposing of the driving units, the first driving units and the second driving units may have the same driving circuits, and the third driving units and the fourth driving units may have the same driving circuits. 
     It should be noted that the first display region  220  in the embodiment of the present disclosure may be an actively driven (AMOLED) display region, and the second display region  240  may be an actively driven (AMOLED) display region or a passively driven (PMOLED) display region. An area of the second display region  240  is much less than that of the first display region  220 , the first display region  220  may be used as a main display region of the display apparatus, and the second display region  240  may be used as an auxiliary display region of the display apparatus. Although the display effect of PMOLED is lower than that of AMOLED, because the area of the second display region is small, the displayed content is also very small, and the second display region  240  can be located at the edge of the display apparatus, and the displayed content is less important, so the first second display region  240  may adopt PMOLED. The passively driven second display region  240  only needs one thin-film transistor (TFT) for driving, and the number of opaque thin-film transistors is very small, which can greatly improve the light transmittance of the second display region  240 . Certainly, in order to make that the display effect of the second display region  240  to be close to that of the first display region  220 , the second display region  240  may also be actively driven (AMOLED). The third display region  260  may select an actively driven (AMOLED) display region or a passively driven (PMOLED) display region as required. 
     In addition to being disposed in the display region of the display apparatus, the first driving unit may also be disposed in a non-display region outside the display region. Please specifically refer to  FIG. 14 , which is a schematic diagram of a fifth partial structure of a display apparatus provided by an embodiment of the present disclosure. The display apparatus  20  may further include a non-display region  280 . The first driving units  248  and second driving units for driving the pixels  246  within the second display region  240  may also be disposed within the non-display region  280 . The display apparatus  20  may be a full screen, that is, the front of the display apparatus  20  is basically a display region, and when viewed from the front of the electronic device, the front of the display apparatus  20  is basically equal to the display surface of the electronic device. However, even if it is a full-screen display apparatus  20 , there is still a non-display region at the edge of the display apparatus  20 . The non-display region can be understood as a black border of the display apparatus  20 , and the width of the black border can be made very narrow, such as the width of the black border less than 1 mm or 0.5 mm, and the like. Because the area of the second display region  240  is small, the number of the second pixels  246  within the second display region  240  is also less, the plurality of second pixels  246  within the second display region  240  are connected in parallel, and the first driving units  248  and second driving units for driving the second pixels  246  within the second display region  240  are also less, the first driving units  248  and second driving units can be arranged at positions in the black border to improve the light transmittance of the second display region  240  without affecting the first display region  220  or the third display region  260 . The second pixel  246  corresponding to the second display region  240  needs to be provided with the plurality of first driving units  248  and second driving units. All of the plurality of first driving units  248  and second driving units can be arranged at the positions in the black border. In order to better accommodate all of the first driving units  248  and second driving units at the positions in the black border, simpler first driving units  248  and second driving units can be used. 
     For example, each of the first driving units  248  and second driving units can use a driving circuit such as 2T1C, 5T1C, and the like, so that the number of thin-film transistors (TFTs) in each of the first driving units  248  and second driving units is less, and the space required by a single first driving units  248  and second driving units is relatively small. The distribution density of the second pixels  246  within the second display region  240  may also be configured to be lower, so that a total number of the first driving units  248  and second driving units within the second display region  240  is less. It should be noted that the plurality of first driving units  248  and the plurality of second driving units may also be partially disposed within the non-display region  280  and partially disposed within the second display region  240  or the third display region  260 . If the second display region adopts PMOLED, each of the driving units within the second display region has only one TFT, which can be disposed within the non-display region. The non-display region may or may not be adjacent to the second display region. If the non-display region can be adjacent to the second display region, the first driving unit may be conveniently disposed within the non-display region. 
     The plurality of second pixels within the second display region may be arranged in a manner of pixel units. Please specifically refer to  FIG. 15 , which is a schematic diagram of a first structure of second pixels within a second display region in a display apparatus according to an embodiment of the present disclosure. The plurality of second pixels  246  within the second display region may be divided into a plurality of pixel units  244 . The second display region includes the plurality of pixel units  244 , and each of the pixel units  244  includes at least three of the second pixels  246  with different colors. One of the pixel units  244  within the second display region can display mixed colors, and one of the pixel units  244  can display a desired color as required. 
     For example, one of the pixel units  244  includes a second pixel  246  with three colors of R, G, and B, which can display various colors, such as red, green, blue, white, pink, and cyan, as required. The second pixels  246  with the same color as at least two of the pixel units  244  within the second display region are connected in parallel to form a pixel set  2422 . 
     For example, four pixel units  244  may form three first-pixel sets  2422 . Specifically, four red pixels  246  are connected in parallel to form a first-pixel set  2422 , four green pixels  246  are connected in parallel to form a first-pixel set  2422 , and four blue pixels  246  are connected in parallel to form a first-pixel set  2422 , so that the four pixel units  244  form one display unit. It should be noted that a pixel unit may also include pixels with multiple colors such as “R, G, B, and W,” or “R, G, B, and Y.” 
     The parallel connection of the second pixels  246  may be formed by the direct connection of the second pixels  246 . 
     For example, the plurality of second pixels  246  are connected in parallel via materials the same as their materials or connected in parallel via connection lines of other materials. The second pixels  246  can also be connected in parallel in other ways. Specifically, the second display region further includes a plurality of metal anodes, one of the second pixels  246  is correspondingly disposed and electrically connected to one of the metal anodes, and the parallel connection of the second pixels can be realized by the parallel connection of the metal anodes. Certainly, the plurality of second pixels  246  connected in parallel in one of the first-pixel sets  2422  may be the plurality of second pixels  246  with the same color. 
     For example, the second pixels  246  of one of the first-pixel sets  2422  are all red pixels or green pixels, or blue pixels. 
     The second display region includes gate lines (not shown in the figure) and data lines. The gate lines, the data lines, and the first driving units cooperate to drive each of the second pixels  246 . The gate lines and the data lines may be arranged in different layers and arranged in a staggered manner. 
     For example, the gate lines are arranged in rows and the data lines are arranged in columns. The arrangement of the second pixels  246  within the second display region may be one of a standard RGB arrangement, a Pentile arrangement, or a Delta arrangement. It should be noted that the data lines and the second pixels  246  are not located on the same layer. 
     When the plurality of second pixels  246  with the same color that are connected in parallel are parallel to the data lines and arranged in columns, one of first driving signal lines  2462  is provided between two columns of the second pixels  246  and electrically connected to the second pixels  246  via second driving signal lines  2464  parallel to the first driving signal lines  2462 . Different pixel arrangement modes have different parallel modes, as shown in  FIGS. 15 and 16 . 
     When a plurality of pixel arrays with the same color that are connected in parallel are arranged, the pixels have different parallel modes. Please specifically refer to  FIGS. 17 and 18 ,  FIG. 17  is a schematic diagram of a third structure of second pixels within a second display region in a display apparatus according to an embodiment of the present disclosure, and  FIG. 18  is a schematic diagram of a fourth structure of second pixels within a second display region in a display apparatus provided by an embodiment of the present disclosure. When the plurality of second pixels  246  with the same color in parallel are arranged in an array manner, adjacent two of the second pixels  246  with the same color that are parallel to a direction of the data lines are connected in parallel via one of the first driving signal lines  2462 , the first driving signal lines  2462  are parallel to the data lines, and the adjacent second pixels  246  with the same color that are perpendicular to the direction of the data lines are connected in parallel via the second driving signal lines  2464 , wherein the second driving signal lines  2464  connecting the second pixels  246  with different colors are arranged at intervals. 
     For ease of understanding,  FIGS. 17 and 18  are used as examples for illustration.  FIG. 17  shows a schematic diagram of the standard RGB arrangement of the pixels  246  within the second display region, and  FIG. 18  shows a schematic diagram of the Delta arrangement of the second pixels  246  within the second display region. The plurality of second pixels  246  are arranged in an array manner, and the second pixels  246  with the same color R, G, or B are arranged in an array manner. One of the first driving signal lines  2462  is arranged next to adjacent two of the second pixels with the same color in the column and are connected in parallel to the second driving signal lines  2464  which are perpendicular to the first driving signal line. Specifically, one of the first driving signal lines  2462  is provided next to the second pixels with the same color adjacent in the column and is connected in parallel to the second driving signal lines  2464  which are perpendicular to the first driving signal line. Among the second pixels with the same color that are adjacent in the row, a B type of second pixels directly connect, at one end, two of the first driving signal lines  2462  in parallel; an R type of second pixels directly connect, at another end, two of the first driving signal lines  2462  in parallel; and a G type of second pixels are connected in parallel via a third driving signal line  2466 , wherein the third driving signal line  2466  bypasses the B type of second pixels and the R type of second pixels disposed between the two columns of the G type of second pixels and separates the driving signal lines connecting the R type of second pixels. It should be noted that the arrangement of the second pixels within the second display region according to the pentiles may also adopt a similar parallel manner, which will not be repeated here. 
     When the plurality of second pixels with the same color that are connected in parallel are perpendicular to the data lines, the second pixels are connected in different parallel manners. Please specifically refer to  FIG. 19 , which is a schematic diagram of a fifth structure of second pixels within a second display region in a display apparatus provided by an embodiment of the present disclosure. The arrangement of the second pixels  246  within the second display region is a standard RGB arrangement or a Pentile arrangement. The plurality of second pixels  246  with the same color that are connected in parallel are perpendicular to the data lines, the first driving signal lines  2462  are arranged along a direction perpendicular to the data lines, and the first driving signal lines  2462  are electrically connected to the second pixel  246  via the second driving signal lines  2464  perpendicular to the first driving signal lines  2462 , wherein the second driving signal lines connecting the second pixels  246  with different colors are arranged at intervals. For ease of understanding, the following takes  FIG. 19  as an example for a detailed description. one of the first driving signal lines  2462  is arranged on each of two sides of the plurality of second pixels  246  with the same color, and one of the first driving signal lines  2462  is arranged in a middle position. The plurality of G type of second pixels  246  are electrically connected to the first driving signal lines  2462  via a plurality of second driving signal lines  2464  perpendicular to the first driving signal lines  2462 , so as to realize the parallel connection of the plurality of G type of second pixels. The plurality of B type of second pixels  246  are connected in parallel in a connection manner similar to the G type of second pixels  246 . The first driving signal lines  2462  electrically connected to the plurality of R type of second pixels  246  are arranged at an end portion. The second display region also includes the third driving signal lines  2466  to which the plurality of R type of second pixels  246  are connected in parallel. The third driving signal lines  2466  bypass the driving signal electrically connected to the G type of second pixel  246  and the B type of pixel  246  to connect the plurality of R type of second pixels  246  in parallel. Specifically, the third driving signal lines  2466  bypass the G type of second pixel  246  on one side opposite to the second driving signal lines  2464  connected to the G type of second pixels  246  and bypass the B type of second pixel  246  on one side opposite to the second driving signal lines  2464  connected to the B type of second pixels  246  in the same manner. It should be noted that the pixels within the second display region may be arranged in a Pentile arrangement in a similar parallel manner, which will not be repeated here. 
     In addition to the parallel connection of the second pixels with the same color in different pixel units to form one pixel set, the second pixels in one pixel unit and the second pixels in at least one of other pixel units may also be connected in parallel to form one pixel set. 
     For example, the R type of second pixels of one pixel unit are connected to the G type of second pixels and the B type of second pixels of another pixel unit in parallel to form one pixel set. For another example, the R type of second pixels of one pixel unit are connected to the G type of second pixels of another pixel unit and the B type of second pixels of a third pixel unit in parallel to form one pixel set. A mixed color display can be performed as required. 
     For example, if the second display region displays a specific icon, the second pixels within the second display region can be connected in parallel according to the specific icon. 
     In addition, the pixel set may also be formed by connecting at least two second pixels with different colors in parallel in the same pixel unit. As shown in  FIG. 20 , the R type of second pixels, the B type of second pixels, and the G type of second pixels in the pixel sets  244  are connected in parallel to form first-pixel sets  2422 . A mixed color display can be performed as required. 
     For example, if the second display region displays a specific icon, the second pixels within the second display region can be connected in parallel according to the specific icon. 
     For example, the second display region displays a signal icon (4G, 5G, WIFI, etc.), an alarm clock icon, and the like. The second display region only needs to display a white or black alarm clock icon or the like. It should be noted that only the second pixels with two colors may be connected in parallel, and the second pixels with the other color may be driven independently.

     For example, the material of the substrate  291  can be polyimide (PI). 
     The driving circuit layer  292  is disposed on the substrate  291 . The driving circuit layer  292  includes the first driving units  248  for driving the second pixels  246  within the second display region. Each of the first driving units  248  includes at least one thin-film transistor TFT. A source and a drain of the thin-film transistor are located in the same layer, and a gate is located between the source and the light-emitting layer. 
     The anode layer  293  is disposed on the driving circuit layer  292 , the anode layer  293  includes a first anode layer  2932 , a first insulation layer  2934 , and a second anode layer  2936 , wherein the first insulation layer  2934  is disposed between the first anode layer  2932  and the second anode layer  2936  to separate and insulate the first anode layer  2932  and the second anode layer  2936 . The first anode layer  2932  includes first signal lines (gate lines) in a first direction, the second anode layer  2936  includes second signal lines (data lines) in a second direction. The first direction and the second direction may be perpendicularly arranged. Each of the first signal lines and the second signal lines is electrically connected to the first driving unit  248 . The driving chip of the display apparatus controls the first driving unit  248  via the first signal line and the second signal line. The first signal lines and the second signal lines can use ITO with high light transmittance to ensure the transmittance of the second display region, and meanwhile, the diffraction caused by the first signal lines and the second signal lines can be reduced. The first signal lines and the gate of each of the first driving units can be located in the same layer, and the second signal lines may be electrically connected to the drain of each of the first driving units  248  via a conductive portion located in a first via hole  2935 . The anode layer  293  may further include a metal anode layer. The metal anode layer is adjacent to the light-emitting layer  294 . The metal anode  2938  of the metal anode layer and the first pixel  226  of the light-emitting layer  294  are directly adjacent and electrically connected. There is a second insulation layer  2939  between the metal anode layer and the source of the first driving unit  248 , wherein the metal anode  2938  can be electrically connected to the source of the first driving unit  248  via a conductive portion located in the pixel via hole. The metal anode  2938  can also use ITO with high light transmission. 
     It should be noted that, in some other embodiments, the metal anode in the metal anode layer and the second signal lines in the second anode layer can be located on the same layer. Namely, the metal anode layer and the second anode layer are located in the same layer, and the first insulation layer and the second insulation layer can be the same layer; the metal anode in the metal anode layer and the second anode layer can also be located in different layers, and the metal anode layer and the second anode layer are separated and insulated by the second insulation layer. 
     The light-emitting layer  294  is disposed on the anode layer  293 . The light-emitting layer  294  includes a pixel definition layer  2942 . The pixel definition layer  2942  has a plurality of pixel holes. Each pixel hole is provided with one first pixel  226 . The first pixel  226  includes an organic light-emitting material.

The common electrode layer  295  may adopt an ITO material with high light transmittance. 
     A planarization layer  296  may also be disposed on the common electrode layer  295 . After the first pixel  226  is disposed in the pixel hole, the first pixel  226  does not fill up the pixel hole. After the common electrode layer  295  is disposed on the first pixel  226 , a groove will appear. The planarization layer  296  can fill in the grooves and cover the entire light-emitting layer  294  to protect the light-emitting layer  294  and the like. 
     The touch layer  297  may also be disposed on the planarization layer  296 . The touch layer  297  may be used to detect a user&#39;s touch operation. 
     A polarizer (not shown in the figure) may also be provided on the touch layer  297 , and the polarizer may be used to prevent internal light from being transmitted out, and prevent the user from seeing the internal components such as the driving units. The touch layer  297  and the polarizer can be pasted together and then disposed on the planarization layer  296 . 
     It should be noted that, in some other embodiments, some structures may be added or removed as required, which is not limited to this embodiment of the present disclosure. 
     For example, at least one of the touch layer  297  and the polarizer can be reduced. For another example, a protective layer can be added between the planarization layer  296  and the touch layer  297 , and the protective layer can be made of the same material as the substrate  291 . 
     All layers within the second display region except the driving circuit layer  292  are made of light-transmitting materials, so as to improve the light transmittance of the second display region. 
     For example, all of the substrate  291 , the pixel definition layer  2942 , the common electrode layer  295 , the planarization layer  296 , and the touch layer  297  within the second display region can be made of light-transmitting materials, and the signal lines in the anode layer  293  can be made of ITO or light-transmitting materials such as nanosilver. The TFTs of the driving circuit layer  292  cannot adopt light-transmitting materials, and parts of the driving circuit layer  292  other than the TFTs can also adopt light-transmitting materials. It can be understood that the solution of improving the second display region by improving the light transmittance of the material and changing the wiring arrangement is involved within the scope of the present disclosure. 
     It should be noted that the first display region may adopt a layered structure similar to that of the second display region.

     The display apparatus further includes a polarizer. The polarizer may have a first polarizer portion corresponding to the second display region. The first polarizer portion may be one or more through holes or light-transmitting material. 
     For example, a through hole is firstly defined corresponding to the second display region, and then a transparent material is filled in the through hole to form the first polarizing portion. For another example, a through hole is firstly defined corresponding to the second display region, and then a material with high light transmittance and low polarization is filled in the through hole to form the first polarizing portion, so that the first polarizing portion can not only realize the function of high light transmittance but also achieve functions of preventing light from being reflected and allowing users to see the internal structure.

The first direction and the second direction can be perpendicularly arranged. Each of the first signal lines and the second signal lines is electrically connected to a first driving unit  248 . A driving chip of the display apparatus controls the first driving unit  248  via the first signal lines and the second signal lines. The first signal lines and the gate in each of the first driving units  248  may be located in the same layer. The second signal lines and the drain in each of the first driving units  248  may be located in the same layer. The anode layer  293  may further include a metal anode layer  2938 . The metal anode layer  2938  is adjacent to the light-emitting layer  294 . The metal anode of the metal anode layer  2938  and the first pixel  226  of the light-emitting layer  294  are directly adjacent and electrically connected.

A light-blocking block  280  is disposed on the second insulation layer  2939  between the metal anode layer  2938  and the second anode layer  2936 . 
     It should be noted that the above layered structure shows an embodiment in which each of the first driving units is located within the second display region.

The stacked structure of each of the second driving units is the same as that of each of the first driving units. The stacked structure of each of the fourth driving units is the same as that of each of the third driving units, which will not be repeated here.

     A lens of a camera in an electronic device faces the substrate of the display apparatus, wherein the camera is used to acquire external light signal passing through the first display region for imaging. In order to reduce the space occupied by the camera, the lens of the camera may be close to or adjacent to the substrate of the display apparatus. The substrate of the display apparatus is mainly used to carry other layer structures of the display apparatus and does not need any special function itself. Because the camera part can be arranged in the substrate, in order to further reduce the space occupied by the camera. Please specifically refer to  FIG. 28 , which is a schematic diagram of a first structure of a display apparatus and a camera provided by an embodiment of the present disclosure. A first mounting hole  2912  is defined at a position of the substrate corresponding to the camera  60 , and the camera  60  is at least partially mounted in the first mounting hole  2912 . The first mounting hole  2912  can be a blind hole, that is, the thickness of a part of the substrate  291  relative to the camera  60  is less than that of the other parts, and the substrate  291  is still a complete substrate  291 , which does not affect its function of carrying other layer structures of the display apparatus  20 , and Part of the space can be freed up to accommodate the camera  60 . The installation manner of the first installation hole  2912  and the camera head  60  can be set according to the dimension of the first installation hole  2912  and the dimension of the camera head  60 . Exemplarily, if the space of the first installation hole  2912  is insufficient to install of the entire camera  60 , the lens  62  of the camera  60  is partially arranged in the first installation hole  2912 . If the camera head  60  is small enough, the entire camera head  60  is disposed in the first mounting hole  2912 . 
     Because the driving circuit layer within the second display region is not provided with the first driving unit, and the driving circuit layer has no special function, the camera can be installed in the driving circuit layer. Please specifically refer to  FIG. 29 , which is a schematic diagram of a second structure of a display apparatus and a camera provided by an embodiment of the present disclosure. The first mounting hole  2912  is a through hole, the driving unit layer within the second display region  240  has a second mounting hole  2922  corresponding to the camera  60 , the first mounting hole  2912  and the second mounting hole  2922  communicate with each other, and the camera  60  may be at least partially located in the second mounting hole  2922  inside the mounting hole  2922 . 
     For example, the lens  62  of the camera  60  is located in the first mounting hole  2912  and the second mounting hole  2922 . The second mounting hole  2922  may be a through hole or a blind hole. The first mounting hole  2912  and the second mounting hole  2922  may be fabricated after the partial laminated structure of the display apparatus  20  is formed. 
     For example, after all of the driving circuit layer, the anode layer, the light-emitting layer, and the common electrode layer of the display apparatus  20  are disposed on the substrate  291 , the first mounting hole  2912  and the second mounting hole  2922  are formed corresponding to the position of the lens  62  of the camera  60  by using a laser or other means. 
     It should be noted that the camera  60  within the second display region  240  can be used as the front camera  60  of the electronic device. The front camera is generally a camera whose lens cannot be moved. The substrate  291  and the driving circuit layer  292  of the display apparatus can be provided with a first installation Hole  2912  and second mounting hole  2922 , the camera  60  corresponding to the second display region  240  can be a camera  60  with a movable lens  62 , wherein the lens  62  of the camera  60  can be moved to realize functions such as auto focus. 
     It can be understood that, in any of the above embodiments, the dimension and shape of the second pixel within the second display region can be configured as required. 
     For example, the second pixel may be shaped as a rectangle shape or a circle-like shape. The circle-like second pixel may be shaped as a circle shape, an ellipse shape, a rounded rectangle shape, or the like. The round-like second pixel can improve the diffraction problem of the second display region because the edge is an arc-shaped transition. 
     The display apparatus may have a regular shape, such as a rectangle, a rectangle with rounded corners, or a circle. 
     Certainly, in some other possible embodiments, the display apparatus may also have an irregular shape, which is not limited to this embodiment of the present disclosure. 
     One camera or a plurality of cameras may be arranged under the second display region. The plurality of cameras can be cameras that cooperate with each other, such as two identical cameras, a normal camera and a blur camera or a black and white camera, and the like. In addition to cameras, other functional devices can be configured under the second display region, such as proximity sensors, light sensors, ranging sensors, fingerprint recognition sensors, and the like.

A cover plate may also be provided on the display apparatus  20 . The cover plate covers the display apparatus  20  to protect the display apparatus  20  and prevent the display apparatus  20  from being scratched or damaged by water.
