Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the orientation words such as "upper" and "lower" usually refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0030] An embodiment of the present application provides a display device, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0031] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the distribution structure of the pixel units of the display panel in the display device of the embodiment of the present application. The display device includes a display panel 1, and the display panel 1 includes a first display area 10 and a second display area 20. The first display area 10 surrounds the second display area 20, that is, the first display area 10 is the display area near the edge of the display panel 1, and the second display area 20 is the display area near the center of the display panel 1.

[0032] The display device includes a backlight module 3, and the backlight module 3 includes a first backlight area 30 and a second backlight area 40. The first backlight area 30 is correspondingly arranged with the first display area 10, and the second backlight area 40 is correspondingly arranged with the second display area 20, that is, the first backlight area 30 is the backlight area of the backlight module 3 close to the edge, and the second backlight area 40 is the backlight area of the backlight module 3 close to the center.

[0033] During the operation of the display device, the backlight source in the backlight area of the backlight module 3 emits backlight rays, and the backlight rays are emitted to the pixel units of the corresponding display area after overlapping and mixing for screen display. The backlight sources in the backlight module 3 are mostly arranged in an array. The overlapping of the backlight rays emitted by the backlight sources located in the edge area is relatively small, resulting in a lower display brightness of the first display area 10 close to the edge when the display panel 1 is displayed, so that there is a display difference between the first display area 10 and the second display area 20, and further affecting the display uniformity of the display device.

[0034] In the embodiment of the present application, the first display area 10 includes a plurality of first pixel units 11, and the first pixel unit 11 includes a first white sub-pixel 111. By arranging the first white sub-pixel 111 in the first pixel unit 11 of the first display area 10, the transmittance of the backlight rays of the first backlight area 30 in the first display area 10 can be increased by using the first white sub-pixel 111, which helps to improve the display brightness of the first display area 10, and further helps to reduce the display brightness difference between the first display area 10 and the second display area 20, and improve the overall display brightness uniformity of the display device.

[0035] In some embodiments, please continue to refer to Figure 1 , in the direction from the first display area 10 towards the second display area 20, the aperture ratio of the first white sub-pixels 111 of the plurality of first pixel units 11 decreases. Since the display brightness of the first display area 10 close to the edge is lower when the display panel 1 is displayed, and the display brightness is lower at the position closer to the edge, there is also a display brightness difference in the first display area 10 itself. By setting the aperture ratio of the first white sub-pixels 111 of the plurality of first pixel units 11 to decrease from the edge towards the direction of the central area, the transmittance of the first display area 10 at the position closer to the edge is greater, which helps to reduce the display brightness difference in the first display area 10, so as to further improve the overall display brightness uniformity of the display device.

[0036] In some embodiments, please continue to refer to Figure 1, the first display area 10 includes a first sub-area 12 and a second sub-area 13. The first sub-area 12 is located on the four peripheral sides of the second display area 20, and the second sub-area 13 is located on the diagonal sides of the second display area 20, that is, the first sub-area 12 is located on the upper, lower, left, and right four sides of the second display area 20, and the second sub-area 13 is located in the four corner areas. Compared with the first sub-area 12, the overlapping of the backlight rays corresponding to the second sub-area 13 is less, making the brightness of the second sub-area 13 lower than that of the first sub-area 12.

[0037] Among them, the aperture ratio of the first white sub-pixel 111 located in the first sub-area 12 is smaller than that of the first white sub-pixel 111 located in the second sub-area 13, so that the penetration rate of the backlight rays in the second sub-area 13 is greater than that in the first sub-area 12, to correct the brightness difference between the second sub-area 13 and the first sub-area 12, thereby improving the brightness uniformity between the second sub-area 13 and the first sub-area 12, and further improving the display brightness uniformity of the entire display device.

[0038] It should be noted that the backlight source used in the display device is mostly a blue LED lamp. The emitted blue light is converted and mixed by the color conversion film into white light, and then exits to the pixel unit corresponding to the display area. However, the backlight rays emitted by the backlight source near the edge area may directly exit to the corresponding pixel unit without passing through the color conversion film, resulting in a problem of blue chromaticity deviation in the first display area 10 located at the edge position.

[0039] Correspondingly, in some embodiments, please continue to refer to Figure 1 , the first pixel unit 11 further includes a first blue sub-pixel 112. In the direction from the first display area 10 towards the second display area 20, the aperture ratio of the first blue sub-pixels 112 of multiple first pixel units 11 increases, that is, the aperture ratio of the first blue sub-pixels 112 closer to the edge position is smaller, and the aperture ratio of the first blue sub-pixels 112 closer to the center position is larger. And the aperture ratio of the first blue sub-pixel 112 directly affects the light output ratio of the blue light. By setting the aperture ratio of the first blue sub-pixels 112 in the first display area 10 to increase from the edge position towards the center position, the light output ratio of the blue light emitted by the first blue sub-pixels 112 closer to the edge position is smaller, which helps to correct the problem of blue chromaticity deviation in the first display area 10, to improve the chromaticity uniformity between the first display area 10 and the second display area 20, and further improve the chromaticity uniformity of the entire display device.

[0040] In some embodiments, please refer to Figure 2 and Figure 3 , Figure 2 is a cross-sectional view of the A-A section in the embodiment of the present application Figure 1 , Figure 3 is a cross-sectional view of the A-A section in the embodiment of the present application Figure 1Cross-sectional view of the B-B section. The first blue sub-pixel 112 includes a first blue color filter 1121. In the direction from the first display area 10 towards the second display area 20, the thickness of the first blue color filter 1121 increases, that is, the thickness of the first blue color filter 1121 closer to the edge position is smaller, and the thickness of the first blue color filter 1121 directly affects the color purity of the blue light. By setting the thickness of the first blue color filter 1121 in the first display area 10 to increase from the edge position towards the center position, the color purity of the blue light emitted by the first blue sub-pixel 112 closer to the edge position is lower, which helps to correct the problem of the chromaticity of the first display area 10 being bluish, so as to improve the chromaticity uniformity between the first display area 10 and the second display area 20, and further improve the chromaticity uniformity of the entire display device.

[0041] It should be noted that, in some embodiments, in the direction from the first display area 10 towards the second display area 20, while setting the aperture ratio of the first blue sub-pixel 112 to increase, the thickness of the first blue color filter 1121 can also be set to increase, so as to correct the chromaticity of the first display area 10 through the synergistic effect of the aperture ratio and the thickness, and further improve the chromaticity uniformity between the first display area 10 and the second display area 20.

[0042] In some embodiments, the first display area 10 includes a first sub-area 12 and a second sub-area 13. The first sub-area 12 is located on the peripheral side of the second display area 20, and the second sub-area 13 is located on the diagonal side of the second display area 20. Compared with the first sub-area 12, the light leakage problem that may occur in the second sub-area 13 is more serious, making the problem of the chromaticity of the second sub-area 13 being bluish relative to the first sub-area 12 more serious.

[0043] Among them, the aperture ratio of the first blue sub-pixel 112 located in the second sub-area 13 is smaller than that of the first blue sub-pixel 112 located in the first sub-area 12, so that the light output ratio of the blue light emitted by the first blue sub-pixel 112 located in the second sub-area 13 is smaller than that of the blue light emitted by the first blue sub-pixel 112 located in the first sub-area 12, so as to correct the chromaticity difference between the second sub-area 13 and the first sub-area 12, thereby improving the chromaticity uniformity between the second sub-area 13 and the first sub-area 12, and further improving the display chromaticity uniformity of the entire display device.

[0044] Alternatively, the thickness of the first blue color filter 1121 located in the second sub-region 13 is less than the thickness of the first blue color filter 1121 located in the first sub-region 12, such that the color purity of the blue light emitted by the first blue sub-pixel 112 in the second sub-region 13 is lower than the color purity of the blue light emitted by the first blue sub-pixel 112 in the first sub-region 12, so as to correct the chromaticity difference between the second sub-region 13 and the first sub-region 12, thereby improving the chromaticity uniformity between the second sub-region 13 and the first sub-region 12, and further improving the display chromaticity uniformity of the entire display device.

[0045] In some embodiments, the first pixel unit 11 further includes a first red sub-pixel 113 and a first green sub-pixel 114. The first red sub-pixel 113 includes a first red color filter 1131, and the first green sub-pixel 114 includes a first green color filter 1141. When the display device is operating, the backlight light overlaps and mixes, and then emits red light after being filtered by the first red color filter 1131, and emits green light after being filtered by the first green color filter 1141. The light filtered by different color filters in the first pixel unit 11 forms a display screen of the corresponding color after mixing. By adjusting the mixing ratio of different colors, different display screens can be achieved.

[0046] Among them, in the direction from the first display area 10 towards the second display area 20, the thickness of the first red color filter 1131 decreases, and the thickness of the first green color filter 1141 decreases. That is, the closer to the edge position, the greater the thickness of the first red color filter 1131 and the first green color filter 1141. The thickness of the first red color filter 1131 and the first green color filter 1141 directly affects the color purity of red light and green light. By setting the thickness of the first red color filter 1131 and the first green color filter 1141 in the first display area 10 to decrease from the edge position towards the center position, the color purity of the red light emitted by the first red sub-pixel 113 and the green light emitted by the first green sub-pixel 114 closer to the edge position is higher, so that the chromaticity of the mixed light emitted by the first pixel unit 11 is yellowish, in order to balance the original bluish chromaticity of the first display area 10, thereby improving the chromaticity uniformity between the first display area 10 and the second display area 20.

[0047] It should be noted that an increase in the thickness of the first red color resistor 1131 and the first green color resistor 1141 will cause a decrease in the transmittance of the first display area 10, thereby resulting in a decrease in the brightness of the first display area 10. In the embodiments of the present application, when increasing the thickness of the first red color resistor 1131 and the first green color resistor 1141 in the first pixel unit 11, the thickness of the first blue color resistor 1121 can be decreased simultaneously, or the design of the first white sub-pixel 111 can be combined simultaneously, so as to correct the blue chromaticity deviation of the first display area 10 while reducing the impact on the display brightness of the first display area 10, thereby improving the chromaticity uniformity and brightness uniformity between the first display area 10 and the second display area 20.

[0048] In some embodiments, the first red sub-pixel 113, the first green sub-pixel 114, and the first blue sub-pixel 112 are arranged along the first direction X, the first white sub-pixel 111 is adjacent to the first blue sub-pixel 112, and the first white sub-pixel 111 and the first blue sub-pixel 112 are arranged along the second direction, and the second direction forms an angle with the first direction X. In the embodiments of the present application, in the direction from the first display area 10 towards the second display area 20, the aperture ratio of the first white sub-pixels 111 of multiple first pixel units 11 decreases, and the aperture ratio of the first blue sub-pixels 112 of multiple first pixel units 11 increases. By arranging the first white sub-pixel 111 adjacent to the first blue sub-pixel 112, the first white sub-pixel 111 and the first blue sub-pixel 112 as a whole can be arranged along the first direction X with the first red sub-pixel 113 and the first green sub-pixel 114, that is, the first white sub-pixel 111 can be directly arranged in the area where the area occupied by the first blue sub-pixel 112 relatively decreases, thereby reducing the impact of the arrangement of the first white sub-pixel 111 on the arrangement of the first pixel unit 11.

[0049] In some embodiments, the second display area 20 includes multiple second pixel units 21, the second pixel unit 21 includes a second blue sub-pixel 211, the second blue sub-pixel 211 includes a second blue color resistor 2111, the aperture ratio of the second blue sub-pixel 211 is greater than or equal to the aperture ratio of the first blue sub-pixel 112, and the thickness of the second blue color resistor 2111 is greater than or equal to the thickness of the first blue color resistor 1121. That is, the second display area 20 is located at a position close to the central area of the display device, and its display brightness and chromaticity are relatively uniform. The aperture ratio of the second blue sub-pixel 211 and the thickness of the second blue color resistor 2111 can be not designed with a gradient, so as to simplify the setting manner of the second pixel units 21 in the second display area 20, thereby simplifying the manufacturing process of the display device and reducing the production cost.

[0050] Correspondingly, the second pixel unit 21 further includes a second red sub-pixel 212 and a second green sub-pixel 213. The second red sub-pixel 212 includes a second red color filter 2121, and the second green sub-pixel 213 includes a second green color filter 2131. The thickness of the second red color filter 2121 is less than or equal to the thickness of the first red color filter 1131, and the thickness of the second green color filter 2131 is less than or equal to the thickness of the first green color filter 1141. That is, the thickness of the second red color filter 2121 and the thickness of the second green color filter 2131 may not be designed with a gradient, so as to simplify the setting manner of the second pixel unit 21 in the second display area 20, thereby simplifying the manufacturing process of the display device and reducing the production cost.

[0051] It should be noted that, in order to further improve the overall display brightness of the display device, the second pixel unit 21 may also include a second white sub-pixel (not shown in the figure) to improve the transmittance of the backlight light in the second display area 20, thereby improving the brightness of the second display area 20. At the same time, the aperture ratio of the second white sub-pixel is less than or equal to the aperture ratio of the first white sub-pixel 111, so as to reduce the brightness difference between the second display area 20 and the first display area 10 while improving the overall display brightness of the display device, thereby ensuring the display brightness uniformity of the entire display device.

[0052] Please refer to Figure 4 , Figure 4 which is a schematic distribution structure diagram of the backlight source of the backlight module in the display device of the embodiment of the present application. The display device includes a first backlight area 30 and a second backlight area 40. The first backlight area 30 is correspondingly arranged with the first display area 10, and the second backlight area 40 is correspondingly arranged with the second display area 20. That is, the first backlight area 30 is the backlight area near the edge of the display device, and the second backlight area 40 is the backlight area near the center of the display device.

[0053] Among them, a plurality of first backlight sources 31 are arranged in the first backlight area 30, and a plurality of second backlight sources 41 are arranged in the second backlight area 40. The driving current of the first backlight source 31 is greater than the driving current of the second backlight source 41. During the operation of the display device, the backlight light emitted by the first backlight source 31 and the second backlight source 41 of the display device is overlapped and mixed and then emitted to the pixel unit of the corresponding display area for screen display. However, the overlap of the backlight light emitted by the first backlight source 31 in the first backlight area 30 (edge area) is relatively small, so that the backlight brightness of the first backlight area 30 is relatively low, resulting in a backlight brightness difference between the first backlight area 30 and the second backlight area 40, and further affecting the display uniformity of the display device.

[0054] In the embodiment of the present application, by setting the driving current of the first backlight 31 to be greater than the driving current of the second backlight 41, the luminous brightness of the first backlight 31 is made higher than that of the second backlight 41, so as to improve the backlight brightness of the first backlight area 30, thereby correcting the display brightness of the first display area 10, reducing the display brightness difference between the first display area 10 and the second display area 20, and further improving the overall display brightness uniformity of the display device.

[0055] In some embodiments, in the direction from the first backlight area 30 towards the second backlight area 40, the driving currents of the plurality of first backlights 31 decrease. Since the overlap of the backlight rays emitted by the first backlights 31 closer to the edge position is less, the corresponding backlight brightness is lower. By setting the driving currents of the plurality of first backlights 31 to decrease in the direction from the first backlight area 30 towards the second backlight area 40, the driving current of the first backlight 31 closer to the edge position is made larger, and the corresponding luminous brightness of the first backlight 31 is also larger, which helps to improve the difference in the backlight brightness of the first backlight area 30 itself, and further reduces the difference in the backlight brightness between the first backlight area 30 and the second backlight area 40, improving the overall display brightness uniformity of the display device.

[0056] In some embodiments, the first backlight area 30 includes a third sub-area 32 and a fourth sub-area 33. The third sub-area 32 is located on the four peripheral sides of the second backlight area 40, and the fourth sub-area 33 is located on the diagonal sides of the second backlight area 40, that is, the third sub-area 32 is located on the upper, lower, left, and right four sides of the second backlight area 40, and the fourth sub-area 33 is located in the four corner areas. Compared with the third sub-area 32, the overlap of the backlight rays emitted by the first backlights 31 corresponding to the fourth sub-area 33 is less, making the backlight brightness of the fourth sub-area 33 lower than that of the third sub-area 32.

[0057] Among them, the driving current of the first backlight 31 located in the third sub-area 32 is less than the driving current of the first backlight 31 located in the fourth sub-area 33, so that the luminous brightness of the first backlight 31 located in the fourth sub-area 33 is higher than that of the first backlight 31 located in the third sub-area 32, so as to correct the difference in the backlight brightness between the fourth sub-area 33 and the third sub-area 32, thereby improving the backlight brightness uniformity between the fourth sub-area 33 and the third sub-area 32, and further improving the overall display brightness uniformity of the display device.

[0058] In some embodiments, the first backlight 31 includes Mini-LEDs, and the second backlight 41 includes Mini-LEDs. That is, the backlight of the backlight module 3 can be composed of a plurality of Mini-LEDs distributed in an array. Since the size of the Mini-LEDs is relatively small, using Mini-LEDs as the backlight can facilitate the backlight design of the backlight module 3 in a relatively small backlight area, which helps the design of the backlight brightness uniformity.

[0059] It should be noted that the first backlight 31 and the second backlight 41 in the embodiments of the present application may be blue Mini-LED lights. The blue light emitted is converted and mixed by the color conversion film into white light, and then is emitted to the pixel units corresponding to the display area for screen display.

[0060] The above has introduced in detail a display device provided by the embodiments of the present application. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
