[0024] Referring to Figure 1 and Figure 2 , the present embodiment provides a display device 100. The display device 100 includes a first light-emitting area 101 and a second light-emitting area 102. The first light-emitting area 101 corresponds to the under-screen camera 200 (as shown in Figure 3 ). The display device 100 includes a substrate 10, a light-emitting unit 20, and a driving unit 30. The light-emitting unit 20 is disposed on the substrate 10, and the density of the light-emitting unit 20 in the first light-emitting area 101 is less than the density of the light-emitting unit 20 in the second light-emitting area 102. The driving unit 30 is disposed on the substrate 10 and located in the second light-emitting area 102, and the driving unit 30 is used to control the light-emitting unit 30 in the first light-emitting area 101 and the second light-emitting area 102 to turn on or off.

[0025] In the display device 100 of the present embodiment, the density of the light-emitting unit 20 in the first light-emitting area 101 is less than the density of the light-emitting unit 20 in the second light-emitting area 102, so that the number of driving units 30 used to control the light-emitting unit 20 in the first light-emitting area 101 to emit light can be reduced. Sufficient driving units 30 can be arranged in the second light-emitting area 102 to ensure that one driving unit 30 can control one light-emitting unit 20 to emit light. By arranging the driving units 30 in the first light-emitting area 101 and the second light-emitting area 102, the overall display effect of the first light-emitting area 101 and the second light-emitting area 102 is effectively balanced, that is, the display effect of the display device 100 is ensured.

[0026] Further description will be made below in conjunction with the drawings.

[0027] Referring to Figure 3 , the present embodiment provides an electronic device 1000. The electronic device 1000 includes a display device 100, an under-screen camera 200, and a housing 300. The display device 100 and the under-screen camera 200 are disposed on the housing 300.

[0028] The display device 100, the under-screen camera 200, and the shell 300 are sequentially stacked, and the under-screen camera 200 is arranged between the display device 100 and the shell 300.

[0029] The electronic device 1000 can be a mobile phone, a tablet computer, a display device, a notebook computer, a smart watch, or the like. The electronic device 1000 in the embodiments of the present application is taken as a mobile phone for example, and it can be understood that the specific form of the electronic device 1000 is not limited to a mobile phone. The shell 300 can be used to install imaging devices, power supply devices, communication devices, and other functional modules of the electronic device 1000, so as to provide dustproof, anti-falling, waterproof, and other protections for the functional modules.

[0030] Please refer to Figure 1 The display device 100 includes a substrate 10, a light emitting unit 20, and a driving unit 30. The light emitting unit 20 and the driving unit 30 are arranged on the substrate 10.

[0031] The display device 100 includes a first light emitting area 101 and a second light emitting area 102. The first light emitting area 101 corresponds to the under-screen camera 200, that is, the under-screen camera 200 is arranged between the first light emitting area 101 and the shell 300.

[0032] More specifically, the substrate 10 is the side of the display device 100 close to the under-screen camera 200, which is mainly used to place the light emitting unit 20 and the driving unit 30 of the display device 100.

[0033] The light emitting unit 20 is arranged on the substrate 10, that is, the light emitting unit 20 is arranged in the first light emitting area 101 and the second light emitting area 102. The density of the light emitting unit 20 in the first light emitting area 101 is less than the density of the light emitting unit 20 in the second light emitting area 102. The density of the light emitting unit 20 represents the number of light emitting units 20 in a unit size, for example, in the first light emitting area 101, 100 light emitting units 20 are placed per inch, and the density of the light emitting unit 20 in the first light emitting area 101 is 100 pixels per inch (Pixels Per Inch, PPI).

[0034] Please refer to Figure 2 The following takes the light emitting unit 20 in the first light emitting area 101 as a first light emitting unit 21 and the light emitting unit 20 in the second light emitting area 102 as a second light emitting unit 22 for example.

[0035] The driving unit 30 is arranged on the substrate 10 and located in the second light emitting area 102. One driving unit 30 is used to control one light emitting unit 20 to emit light.

[0036] Specifically, one driving unit 30 can control one first light emitting unit 21 to emit light, and one driving unit 30 can also control one second light emitting unit 22 to emit light.

[0037] More specifically, the resolution of the display device 100 is related to the density of the light emitting units 20. For example, the density of the first light emitting units 21 is 400 PPI, and the resolution of the first light emitting area 101 is 400 PPI. The density of the second light emitting units 22 is 450 PPI, and the resolution of the second light emitting area 102 is 450 PPI.

[0038] The resolution of the display device 100 is also related to the number of driving units 30 used to control the light emitting units 20 to emit light. When one driving unit 30 controls multiple light emitting units 20 to emit light, the actual resolution of the display device 100 displayed will not reach the density of the light emitting units 20. For example, the density of the first light emitting units 21 is 400 PPI, i.e. the resolution of the first light emitting area 101 is 400 PPI. When one driving unit 30 controls multiple first light emitting units 21 to emit light, the actual resolution of the first light emitting area 101 displayed is 400 / 1.2 = 333 PPI, i.e. less than 400 PPI. When one driving unit 30 controls one first light emitting unit 21 to emit light, the actual resolution of the first light emitting area 101 displayed is 400 PPI.

[0039] In addition, when the under-screen camera 200 is arranged on the electronic device 1000, the display effect of the display device 100 and the shooting effect of the under-screen camera 200 need to be ensured at the same time. The display effect needs to ensure that the under-screen area (the first light emitting area 101) and the non-under-screen area (the second light emitting area 102) maintain the same design as much as possible. The shooting needs more light amount and full-spectrum transmittance, but more light amount needs to reduce the pixel design of the first light emitting area 101, i.e. reduce the density of the first light emitting units 21, which will cause the display effect of the display device 100 to be poor.

[0040] The light emitting units 20 of the display device 100 are arranged by one of the following two schemes:

[0041] Scheme one: built-in method, the built-in method is to place the driving unit 30 in the first light emitting area 101, which mainly reduces the arrangement density of the first light emitting unit 21 in the first light emitting area 101, and the first light emitting area 101 corresponds to the under-screen camera 200, that is, the size of the first light emitting area 101 is fixed, after reducing the density of the first light emitting unit 21, the number of light emitting units 20 in the first light emitting area 101 will be reduced, therefore, the number of driving units 30 for controlling the light emitting units 20 can be reduced. Wherein, the driving unit 30 is a non-light-transmitting material, therefore, after reducing the number of driving units 30 in the first light emitting area 101, the transmittance of the first light emitting area 101 can be improved, thereby ensuring the shooting effect of the under-screen camera 200, but reducing the arrangement number of the first light emitting unit 21 will lead to a large difference between the density of the first light emitting unit 21 and the density of the light emitting unit 20 in the second light emitting area 102, thereby affecting the display effect of the display device 100.

[0042] Scheme two: external method, the external method is to place the driving unit 30 in the second light emitting area 102, which mainly does not place the driving unit 30 in the first light emitting area 101, thereby ensuring better transmittance of the first light emitting area 101 to ensure the shooting effect of the under-screen camera 200. However, due to the limited size of the second light emitting area 102, the driving unit 30 corresponding to the light emitting unit 20 in the first light emitting area 101 is also arranged in the second light emitting area 102 by the external method, realizing that one driving unit 30 controls the opening or closing of multiple light emitting units 20 in the first light emitting area 101 and the second light emitting area 102, which will cause obvious jaggies on the display quality of the display device 100, that is, the display quality of the display device 100 will be poor.

[0043] And in the display device 100 and the electronic equipment 1000 of the embodiment of the application, one driving unit 30 controls one light emitting unit 20 to emit light, which can ensure that the actual display resolution of the display device 100 is high, thereby ensuring the display effect. The density of the first light emitting unit 21 is less than the density of the second light emitting unit 22, and the density of the first light emitting unit 21 is close to the density of the second light emitting unit 22, which not only ensures that the display picture of the display device 100 is good in integrity, but also ensures that a sufficient number of driving units 30 can be arranged in the second light emitting area 102 to control the opening or closing of the first light emitting unit 21, effectively improving the consistency of the display effect.

[0044] Please refer to Figure 2The driving unit 30 comprises a first driving unit 31 and a second driving unit 32. The first driving unit 31 is used to drive the light emitting unit 20 of the first light emitting area 101, i.e. the first light emitting unit 21 emits light. The second driving unit 32 is used to drive the light emitting unit 20 of the second light emitting area 102, i.e. the second light emitting unit 22 emits light.

[0045] It can be understood that one first driving unit 31 is used to drive one first light emitting unit 21 to emit light, and one second driving unit 32 is used to drive one second light emitting unit 22 to emit light.

[0046] The first driving unit 31 is connected with the first light emitting unit 21 through the wire 40. When the first driving unit 31 drives the first light emitting unit 21 to emit light, the voltage can be transmitted through the wire 40 to make the first light emitting unit 21 emit light.

[0047] Specifically, as shown in Figure 4 , the first driving unit 31 is arranged close to the edge of the first light emitting area 101. The edge of the first light emitting area 101 is the boundary position between the first light emitting area 101 and the second light emitting area 102. That is, the first driving unit 31 is arranged near the first light emitting area 101, such as above the first light emitting area 101, below the first light emitting area 101, left of the first light emitting area 101, and right of the first light emitting area 101.

[0048] Please refer to Figure 2 and Figure 4 , the second driving unit 32 is arranged on the substrate 10 and located on the second light emitting area 102. The second driving unit 32 is located between two adjacent first driving units 31. The density of the first light emitting unit 21 is less than the density of the second light emitting unit 22, and the second light emitting area 102 can accommodate a sufficient number of first driving units 31. One first driving unit 31 is used to control the opening or closing of one first light emitting unit 21 to improve the display effect of the display device 100.

[0049] Please refer to Figure 4 and Figure 5 , it can be seen that the light emitting unit 20 of the second light emitting area 102 and the second driving unit 32 are stacked on the substrate 10, and the second driving unit 32 is located between the substrate 10 and the light emitting unit 20 (the second light emitting unit 22) of the second light emitting area 102.

[0050] In this way, the area occupied by the second light emitting unit 22 and the second driving unit 32 in the second light emitting area 102 can be reduced, so that more first driving units 31 can be placed in the second light emitting area 102, and the density of the first light emitting unit 21 in the first light emitting area 101 can be increased when the number of the first driving units 31 is increased, so as to further improve the resolution of the first light emitting area 101, thereby improving the display effect of the display device 100.

[0051] Please refer to Figure 2 Since the distance between each first driving unit 31 and the corresponding first light emitting unit 21 is different, the length of the wire 40 is different, so that the resistance is different, and then when the first driving unit 31 drives the first light emitting unit 21 to emit light, the brightness of each first light emitting unit 21 is different, so that the actual display brightness and chroma of the first light emitting area 101 is greatly lower, thereby resulting in poor display effect of the display device 100.

[0052] In some embodiments, please refer to Figure 6 The first light emitting area 101 further includes a low brightness area 1011 and a high brightness area 1012. The low brightness area 1011 and the high brightness area 1012 are preset areas. As described above, since the distance between each first driving unit 31 and the corresponding first light emitting unit 21 is different, the brightness of each first light emitting unit 21 is different, so that the distance between the first driving unit 31 and the corresponding first light emitting unit 21 can be used to predict the area where the first light emitting unit 21 with lower brightness appears, i.e. the low brightness area 1011.

[0053] In this way, when the first driving unit 31 drives the first light emitting unit 21 in the low brightness area 1011 to emit light, the driving voltage of the first light emitting unit 21 in the low brightness area 1011 can be increased based on the preset ratio, so as to improve the brightness of the first light emitting unit 21 in the low brightness area 1011, thereby ensuring that the brightness of each light emitting unit 20 in the first light emitting area 101 is the same, so as to ensure the display effect of the first light emitting area 101, i.e. the display effect of the display device 100. The preset ratio can be set according to the ratio of the theoretical display brightness of the low brightness area 1011 and the high brightness area 1012.

[0054] Please refer to Figure 7 In some embodiments, the display device 100 can include a scan electrode 50 and a data electrode 60. The scan electrode 50 is used to turn on or off the light emitting unit 20 in the selected row, and the data electrode 60 is used to provide the driving voltage of the light emitting unit 20 in the selected column.

[0055] In other words, the number of scan electrodes 50 is plural, each scan electrode 50 is used to control a row of light emitting units 20 to emit light, and the number of data electrodes 60 is plural, each data electrode is used to control the voltage of each column of light emitting units 20 to emit light. That is, the scan electrode 50 combines with the data electrode 60 to control whether the light emitting unit 20 emits light, and control the voltage value of the light emitting unit 20 to emit light when the light emitting unit 20 emits light.

[0056] Specifically, please combine Figure 7 , the scan electrode 50 is a plurality of rows, and the data electrode 60 is a plurality of columns, each row of scan electrodes 50 is connected with the corresponding row of driving units 30 to control the corresponding row of light emitting units 20 to emit light, and each data electrode 60 is used to control the driving voltage of the corresponding column of light emitting units 20.

[0057] It should be noted that the density of the light emitting units 20 in the first light emitting area 101 is different from that of the light emitting units 20 in the second light emitting area 102, that is, the distance between adjacent first light emitting units 21 and the distance between adjacent second light emitting units 22 are different. Therefore, the first light emitting unit 21 and the second light emitting unit 22 cannot be uniformly arranged in the same row or column. Thus, when the display device 100 displays an image, the shear phenomenon will occur at the junction of the first light emitting area 101 and the second light emitting area 102.

[0058] In the display device 100 of the embodiment of the present application, the first light emitting area 101 can be processed separately to eliminate the shear phenomenon occurring at the junction of the first light emitting area 101 and the second light emitting area 102.

[0059] Specifically, in the first light emitting area 101, the first driving unit 31 corresponding to the Nth row of light emitting units 20 and the second driving unit 32 corresponding to the light emitting unit 20 of the Mth row of the second light emitting area 102 with the smallest row spacing from the Nth row of light emitting units 20 are connected to the same scan electrode 50. That is, the first driving unit 31 corresponding to the Nth row of first light emitting units 21 and the second light emitting unit 22 of the Mth row with the smallest row spacing from the Nth row of first light emitting units 21 are connected to the same scan electrode 50.

[0060] Similarly, in the first light emitting area 101, the first driving unit 31 corresponding to the Nth column of light emitting units 20 and the second driving unit 32 corresponding to the light emitting unit 20 of the Mth column of the second light emitting area 102 with the smallest column spacing from the Nth column of light emitting units 20 are connected to the same data electrode 60. That is, the first driving unit 31 corresponding to the Nth column of first light emitting units 21 and the second light emitting unit 22 of the Mth column with the smallest column spacing from the Nth column of first light emitting units 21 are connected to the same data electrode 60.

[0061] Please combine Figure 7 The left side is the second light-emitting area 102, and the right side is the first light-emitting area 101. Since the first light-emitting units 21 and the second light-emitting units 22 cannot be evenly arranged in the same row, the multiple rows of scan electrodes 50 cannot be evenly arranged. Similarly, please combine Figure 8 The upper side is the second light-emitting area 102, and the lower side is the first light-emitting area 101. Since the first light-emitting units 21 and the second light-emitting units 22 cannot be evenly arranged in the same column, the multiple columns of data electrodes 60 cannot be evenly arranged.

[0062] Please combine Figure 7 Take the third row of scan electrodes 50 as an example. It can be seen that the first light-emitting unit 21 in the third row and the second light-emitting unit 22 in the third row are not located in the same row. If the first light-emitting unit 21 and the second light-emitting unit 22 are controlled to emit light at the same time through the third row of scan electrodes 50, then the shear phenomenon will occur at the junction of the first light-emitting area 101 and the second light-emitting area 102.

[0063] Therefore, when the third row of scan electrodes 50 controls the light-emitting units 20 to emit light, it is necessary to first determine whether the third row of scan electrodes 50 has the smallest row spacing with the first light-emitting unit 21 in the third row.

[0064] If the third row of scan electrodes 50 has the smallest row spacing with the first light-emitting unit 21 in the third row, then the first driving unit 31 corresponding to the first light-emitting unit 21 in the third row and the second driving unit 32 corresponding to the second light-emitting unit 22 in the third row are connected to the third row of scan electrodes 50. At this time, it indicates that the first light-emitting unit 21 in the third row and the second light-emitting unit 22 in the third row are approximately located on the same straight line, and the third row of light-emitting units 20 are controlled to emit light through the same scan electrode 50, which will not cause the shear phenomenon.

[0065] If the fourth row of scan electrodes 50 has the smallest row spacing with the first light-emitting unit 21 in the third row, then the third row of scan electrodes 50 only controls the second light-emitting unit 22 in the third row to emit light, and the first driving unit 31 corresponding to the first light-emitting unit 21 in the third row and the second driving unit 32 corresponding to the second light-emitting unit 22 in the fourth row of the second light-emitting area 102 are connected to the same scan electrode 50, that is, the fourth row of scan electrodes 50. The fourth row of scan electrodes 50 controls the first light-emitting unit 21 in the third row to emit light, and the first light-emitting unit 21 in the third row and the second light-emitting unit 22 in the fourth row are approximately located on the same straight line. In this way, it can be ensured that the display device 100 will not appear the shear phenomenon when displaying an image.

[0066] Similarly, please combine Figure 8With the third data electrode 60 as an example, it can be seen that the first light emitting unit 21 in the third column and the second light emitting unit 22 in the third column are not located in the same column, and if the driving voltage of the first light emitting unit 21 and the second light emitting unit 22 is controlled simultaneously by the third data electrode 60, the shear phenomenon will occur at the junction of the first light emitting region 101 and the second light emitting region 102.

[0067] Therefore, when the third data electrode 60 controls the light emitting unit 20 to emit light, it is necessary to determine whether the third data electrode 60 is the data electrode with the smallest column spacing from the first light emitting unit 21 in the third column.

[0068] If the third data electrode 60 is the data electrode with the smallest column spacing from the first light emitting unit 21 in the third column, the first driving unit 31 corresponding to the first light emitting unit 21 in the third column and the second driving unit 32 corresponding to the second light emitting unit 22 in the third column are connected to the third data electrode 60. At this time, it indicates that the first light emitting unit 21 in the third column and the second light emitting unit 22 in the third column are approximately located on the same straight line, and the light emitting unit 20 in the third column is controlled by the same driving voltage to emit light, which will not cause the shear phenomenon.

[0069] If the fourth data electrode 60 is the data electrode with the smallest column spacing from the first light emitting unit 21 in the third column, the third data electrode 60 only controls the second light emitting unit 22 in the third column to emit light, and the first driving unit 31 corresponding to the first light emitting unit 21 in the third column and the second driving unit 32 corresponding to the second light emitting unit 22 in the fourth column are connected to the same data electrode 60, that is, the fourth data electrode 60. The fourth data electrode 60 controls the first light emitting unit 21 in the third column to emit light, and the first light emitting unit 21 in the third column and the second light emitting unit 22 in the fourth column are approximately located on the same straight line. Therefore, the shear phenomenon can be avoided when the display device 100 displays an image.

[0070] Please refer to Figures 1 to 3 and Figure 9 The display method provided by the embodiments of the present application includes the following steps:

[0071] 01: The light emitting unit 20 in the first light emitting region 101 and the second light emitting region 102 is controlled to be turned on or off by the driving unit 30.

[0072] The display method provided by the embodiments of the present application can be applied to the display device 100 and the electronic equipment 1000.

[0073] Specifically, the electronic equipment 1000 can further include a processor 400. When the processor 400 receives a control signal for controlling the light emitting unit 20 to emit light, the processor 400 can control one light emitting unit 20 to emit light by one driving unit 30.

[0074] Thus, since the density of the light emitting units 20 in the first light emitting area 101 is less than the density of the light emitting units 20 in the second light emitting area 102, the number of the driving units 30 for controlling the light emitting units 20 in the first light emitting area 101 to emit light can be reduced, so that enough driving units 30 can be arranged in the second light emitting area 102 to ensure that one driving unit 30 can control one light emitting unit 20 to emit light, thereby ensuring the display effect of the first light emitting area 101, i.e. ensuring the display effect of the display device 100.

[0075] Please refer to Figures 1 to 3 , Figure 9 The display method of the embodiments of the present application further comprises the steps of:

[0076] 03: driving the light emitting units 20 in the Nth row of the first light emitting area 101 and the light emitting units 20 in the Mth row of the second light emitting area 102 with the minimum row spacing from the light emitting units 20 in the first light emitting area 101 to emit light by the same scanning signal; and

[0077] 05: controlling the driving voltage of the light emitting units 20 in the Nth column of the first light emitting area 101 and the light emitting units 20 in the Mth column of the second light emitting area 102 with the minimum column spacing from the light emitting units 20 in the first light emitting area 101 by the same data signal, N and M are positive integers, and N and M are not the same.

[0078] In some embodiments, the processor 400 can be used to execute the methods in steps 03 and 05. That is, the processor 400 is configured to drive the light emitting units 20 in the Nth row of the first light emitting area 101 and the light emitting units 20 in the Mth row of the second light emitting area 102 with the minimum row spacing from the light emitting units 20 in the first light emitting area 101 to emit light by the same scanning signal; and control the driving voltage of the light emitting units 20 in the Nth column of the first light emitting area 101 and the light emitting units 20 in the Mth column of the second light emitting area 102 with the minimum column spacing from the light emitting units 20 in the first light emitting area 101 by the same data signal, N and M are positive integers, and N and M are not the same.

[0079] Specifically, since the density of the light emitting units 20 in the first light emitting area 101 is different from the density of the light emitting units 20 in the second light emitting area 102, i.e. the distance between adjacent first light emitting units 21 is different from the distance between adjacent second light emitting units 22. Therefore, the first light emitting units 21 and the second light emitting units 22 cannot be uniformly arranged in the same row or the same column. Thus, when the display device 100 displays an image, the first light emitting area 101 and the second light emitting area 102 will have a shear at the junction.

[0080] In order to eliminate the shear phenomenon occurring when the display device 100 displays an image. When the light emitting unit 20 is controlled to emit light, the processor 400 can drive the light emitting unit 20 of the Nth row of the first light emitting area 101 and the light emitting unit 20 of the Mth row of the second light emitting area 102 with the smallest row spacing from the light emitting unit 20 of the first light emitting area 101 to emit light by the same scanning signal, and control the driving voltage of the light emitting unit 20 of the Nth column of the first light emitting area 101 and the light emitting unit 20 of the Mth row of the second light emitting area 102 with the smallest column spacing from the light emitting unit 20 of the first light emitting area 101 by the same data signal, wherein N and M are positive integers.

[0081] More specifically, please combine Figure 7 , the left side is the second light emitting area 102, and the right side is the first light emitting area 101. Since the first light emitting unit 21 and the second light emitting unit 22 cannot be uniformly arranged in the same row, the plurality of row scanning electrodes 50 cannot be uniformly arranged. Similarly, please combine Figure 8 , the upper side is the first light emitting area 101, and the lower side is the second light emitting area 102. Since the first light emitting unit 21 and the second light emitting unit 22 cannot be uniformly arranged in the same column, the plurality of column data electrodes 60 cannot be uniformly arranged.

[0082] Please combine Figure 7 , and take the third row of scanning electrodes 50 as an example. It can be seen that the first light emitting unit 21 of the third row and the second light emitting unit 22 of the third row are not located in the same row. If the first light emitting unit 21 and the second light emitting unit 22 are controlled to emit light by the third row of scanning electrodes 50 at the same time, the shear phenomenon occurring at the junction of the first light emitting area 101 and the second light emitting area 102 will be caused.

[0083] Therefore, when the light emitting unit 20 is controlled to emit light by the third row of scanning electrodes 50, it is necessary to first determine whether the third row of scanning electrodes 50 has the smallest row spacing from the first light emitting unit 21 of the third row.

[0084] If the third row of scanning electrodes 50 has the smallest row spacing from the first light emitting unit 21 of the third row, the first driving unit 31 corresponding to the first light emitting unit 21 of the third row and the second driving unit 32 corresponding to the second light emitting unit 22 of the third row are connected to the third row of scanning electrodes 50. At this time, it indicates that the first light emitting unit 21 of the third row and the second light emitting unit 22 of the third row are approximately located on the same straight line, and the light emitting unit 20 of the third row is controlled to emit light by the same scanning electrode 50, which will not cause the shear phenomenon.

[0085] If the minimum row spacing of the first light emitting unit 21 of the third row is the scan electrode 50 of the fourth row, the scan electrode 50 of the third row only controls the second light emitting unit 22 of the third row to emit light, the first driving unit 31 corresponding to the first light emitting unit 21 of the third row is connected to the same scan electrode 50 as the second driving unit 32 corresponding to the second light emitting unit 22 of the fourth light emitting region 102, that is, the scan electrode 50 of the fourth row, that is, the scan electrode 50 of the fourth row controls the first light emitting unit 21 of the third row to emit light, and the first light emitting unit 21 of the third row and the second light emitting unit 22 of the fourth row are approximately on a straight line, so that the display device 100 can ensure that no shear phenomenon occurs when displaying an image.

[0086] The method of connecting the data electrode 60 by the driving unit 30 of the light emitting unit 20 in the same column is consistent with the method of connecting the scan electrode 50 by the driving unit 30 of the light emitting unit 20 in the same row, which will not be described here.

[0087] Please refer to Figures 1 to 3 , Figure 5 and Figure 9 , the display method of the embodiment of the present application further comprises the step of:

[0088] 04: Based on the preset proportion, the driving voltage corresponding to the light emitting unit 20 of the low brightness region 1011 in the data signal is increased.

[0089] In some embodiments, the processor 400 is configured to perform the method in step 04. That is, the processor 400 is configured to increase the driving voltage corresponding to the light emitting unit 20 of the low brightness region 1011 in the data signal based on the preset proportion.

[0090] Specifically, the first light emitting region 101 can be divided into a low brightness region 1011 and a high brightness region 1012. The low brightness region 1011 and the high brightness region 1012 are preset regions. As can be seen from the above, since the distance between each first driving unit 31 and the corresponding first light emitting unit 21 is different, the brightness of each first light emitting unit 21 will be different.

[0091] Therefore, the processor 400 can determine the region where the first light emitting unit 21 with lower brightness, that is, the low brightness region 1011, based on the distance between the first driving unit 31 and the corresponding first light emitting unit 21.

[0092] Thus, when the first driving unit 31 drives the first light emitting unit 21 in the low brightness area 1011 to emit light, the driving voltage of the first light emitting unit 21 in the low brightness area 1011 can be increased according to the preset ratio, so as to increase the brightness of the first light emitting unit 21 in the low brightness area 1011, thereby ensuring that the brightness of each light emitting unit 20 in the first light emitting area 101 is the same, and ensuring the display effect of the first light emitting area 101, that is, the display effect of the display device 100.

[0093] For example, the brightness of the first light emitting unit 21 in the high brightness area is 500 cd / m2, and the brightness of the first light emitting unit 21 in the low brightness area 1011 is 300 cd / m2. Thus, the processor 400 can increase the driving voltage of the first light emitting unit 21 in the low brightness area 1011 according to the ratio of the brightness of the first light emitting unit 21 in the high brightness area and the brightness of the first light emitting unit 21 in the low brightness area 1011, so as to increase the brightness of the first light emitting unit 21 in the low brightness area 1011 to 500 cd / m2. 2 , and the brightness of the first light emitting unit 21 in the low brightness area 1011 is 300 cd / m2. Thus, the processor 400 can increase the driving voltage of the first light emitting unit 21 in the low brightness area 1011 according to the ratio of the brightness of the first light emitting unit 21 in the high brightness area and the brightness of the first light emitting unit 21 in the low brightness area 1011, so as to increase the brightness of the first light emitting unit 21 in the low brightness area 1011 to 500 cd / m2. 2 , thereby improving the display effect of the display device 100.
