Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a display panel and a display device. Background Art

[0002] With the continuous development of liquid crystal displays, the requirement for the screen-to-body ratio has become increasingly high, and the concept of a full-screen display has gradually emerged, that is, the screen-to-body ratio of a full-screen display reaches approximately 100%. With the development of full-screen technologies, under-screen camera technology has gradually entered the panel industry and become the mainstream camera hiding technology. Under-screen camera technology (Under Panel Camera) means placing the camera under the display screen, and at the same time, the display screen in the camera area can still be normally displayed, thereby realizing a true full-screen display technology. However, currently, for a display panel that wants to achieve a full screen and also take into account the front camera, such as a mobile phone, the front camera needs to be set in the display area of the display panel. However, the biggest current difficulty lies in not affecting the display in the display area while ensuring the camera shooting quality.

[0003] And the most important of all is the display problem in the display area. For example, at the position of the camera, the edge display has severe jaggedness and cannot achieve gray-scale transition. This has currently become a problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide a display panel and a display device to solve the problem of severe jaggedness when displaying at the edge of the camera position.

[0005] This application discloses a display panel, including a first display area and a second display area. The bottom of the second display area is used to install micro-components. The display panel further includes a plurality of first pixel units and a plurality of second pixel units. The plurality of first pixel units are arranged in the first display area, and the plurality of second pixel units are arranged in the second display area. Among them, the area of each second pixel unit is smaller than the area of each first pixel unit; the density of the first pixel units in the first display area is smaller than the density of the second pixel units in the second display area.

[0006] Optionally, the area of the sub-pixels in the second pixel unit is less than or equal to half of the area of the sub-pixels of the same color in the first pixel unit; the density of the first pixel units in the first display area is less than or equal to half of the density of the second pixel units in the second display area.

[0007] Optionally, the display panel includes a plurality of first data lines, a plurality of second data lines, and scan lines. The plurality of first data lines provide data signals for the first pixel units, and the plurality of second data lines provide data signals for the second pixel units. The extending directions of the first data lines and the second data lines are the same.

[0008] Optionally, the second display area includes a third transition area and a fourth display area. The third transition area is disposed around the fourth display area. The bottom of the fourth circular display area is used to mount micro-components. The second pixel units are disposed in the third transition area. The second pixel units or the first pixel units are disposed in the fourth display area.

[0009] Optionally, the third transition area is annular, the fourth display area is circular, and the third transition area is disposed between the first display area and the fourth display area. Only the first pixel units are disposed in the fourth display area.

[0010] Optionally, the second pixel unit includes a second red sub-pixel, a second green sub-pixel, and a second blue sub-pixel. In one second pixel unit, the second red sub-pixel, the second green sub-pixel, and the second blue sub-pixel are arranged in a direction perpendicular to the data line. Along the direction of the first data line, adjacent two second red sub-pixels or second green sub-pixels or second blue sub-pixels are a main area sub-pixel and a secondary area sub-pixel respectively.

[0011] Optionally, when the display panel is in the first state, the second pixel units display normally. When the display panel is in the second state, the brightness of the second pixel units gradually decreases in the extending direction from the first display area to the fourth display area.

[0012] Optionally, the second pixel unit includes three second sub-pixels. In the second display area, two columns of the second sub-pixels are disposed between adjacent two first data lines. The second data line is disposed between adjacent two first data lines. Between adjacent two first data lines, one column of the two columns of second sub-pixels is connected to the first data line, and the other column is connected to the second data line.

[0013] Optionally, the second pixel unit includes three second sub-pixels. In the second display area, multiple columns of the second sub-pixels are arranged corresponding to multiple second data lines one by one. Two columns of the second sub-pixels are disposed between adjacent two first data lines. The first data line and the second data line are in different layers, and in the projection of the display panel on the substrate, part of the first data lines coincide with the second data lines.

[0014] The present application also discloses a display device, including a driving circuit and the above-mentioned display panel.

[0015] In this application, the area of the second pixel units in the second display area is set to be smaller, and the density of the second pixel units is greater, so that the number of second pixel units in the area between the second display area and the first display area is larger. When the display panel is displaying, due to the boundary problem between the first display area and the second display area, the difference between the first display area and the second display area is relatively large. Therefore, in this application, the second pixel units at the edge positions of the first display area and the second display area can be set as a gray-scale transition area. And because the density of the second pixel units is large, there are more second pixel units per unit area, so that the data of the sub-pixels is not restricted during the gray-scale transition, and the transition is as smooth as possible, improving the boundary problem between the first display area and the second display area during display, and solving the problem of serious jaggedness when displaying at the edge position of the camera.

Thus, unless otherwise specified, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; the meaning of "a plurality" is two or more.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] The present application will be described in detail below with reference to the drawings and optional embodiments.

[0028] Figure 1 is a schematic diagram of the display panel of the present application, Figure 2 is a schematic diagram of the pixels in the first display area of the display panel of the present application, Figure 3 is a schematic diagram of the pixels in the second display area of the display panel of the present application. Refer to Figures 1-3As shown in the figure, the present application discloses a display panel. The display panel 1 includes a first display area 2 and a second display area 3. The bottom of the second display area 3 is used to install micro-components. The display panel 1 further includes a plurality of first pixel units 10 and a plurality of second pixel units 20. The plurality of first pixel units 10 are arranged in the first display area 2, and the plurality of second pixel units 20 are arranged in the second display area 3. Among them, the area of each second pixel unit 20 is smaller than the area of each first pixel unit 10. The density of the first pixel units 10 in the first display area 2 is less than the density of the second pixel units 20 in the second display area 3.

[0029] In the present application, by setting the area of the second pixel units 20 in the second display area 3 to be smaller and the density of the second pixel units 20 to be greater, the number of second pixel units 20 in the area between the second display area 3 and the first display area 2 is more. When the display panel 1 is displaying, due to the boundary problem between the first display area 2 and the second display area 3, the difference between the first display area 2 and the second display area 3 is relatively large. Therefore, in the present application, the second pixel units 20 at the edge positions of the first display area 2 and the second display area 3 can be set as a gray-scale transition area. And because the density of the second pixel units 20 is large, there are more second pixel units 20 per unit area, so that the data of the sub-pixels are not restricted during gray-scale transition and can be as smooth as possible, improving the boundary problem between the first display area 2 and the second display area 3 during display and solving the problem of serious jaggedness at the edge during display at the position of the camera.

[0030] It can be understood that the micro-components installed at the bottom of the second display area 3 include but are not limited to cameras, iris recognition sensors, 3D structured light sensors, infrared sensors, etc. Moreover, the second display area 3 can display a normal picture and is in a dark state when not displaying.

[0031] Specifically, the area of the sub-pixels in the second pixel units 20 is less than or equal to half of the area of the sub-pixels of the same color in the first pixel units 10. The density of the first pixel units 10 in the first display area 2 is less than or equal to half of the density of the second pixel units 20 in the second display area 3.

[0032] In this embodiment, when the area of the subpixels in the second pixel unit 20 is half the area of the subpixels of the same color in the first pixel unit 10, the number of subpixels in the second pixel unit 20 per unit area is twice the number of subpixels in the first pixel unit 10. Furthermore, within the same grayscale region between the first display area 2 and the second display area 3, the second pixel unit 20 has a greater number of subpixels. When implementing grayscale transitions, if the number of subpixels is small, for example, only five subpixel transitions are provided, then when transitioning from grayscale 255 to grayscale 0, five transitions occur: 255, 200, 150, 100, 50, and 0. However, if the number of subpixels is doubled, ten transitions occur: 255, 225, 200, 175, 150, 125, 100, 75, 50, 25, and 0. In comparison, while the transition area remains unchanged, the resulting transition image is smoother.

[0033] Specifically, the area of the sub-pixel in the second pixel unit 20 is equal to half the area of the sub-pixel of the same color in the first pixel unit 10. That is, two sub-pixels of the second pixel unit 20 are set in a sub-pixel area of the first pixel unit 10 between two data lines.

[0034] Among them, the first pixel unit 10 and the second pixel unit 20 respectively adopt an RGB strip pixel arrangement, that is, the second pixel unit 20 includes a second red sub-pixel 22, a second green sub-pixel 23, and a second blue sub-pixel 24; in one second pixel unit 20, the second red sub-pixel 22, the second green sub-pixel 23, and the second blue sub-pixel 24 are arranged in a direction perpendicular to the data line, that is, extend in the direction of the scan line.

[0035] In addition to the first data lines 30, the second display area 3 also includes second data lines 31 that provide data signals to the second pixel units 20. The display panel 1 includes a plurality of first data lines 30, a plurality of second data lines 31, and scan lines. The plurality of first data lines 30 provide data signals to the first pixel units 10, and the plurality of second data lines 31 provide data signals to the second pixel units 20. The first data lines 30 and the second data lines 31 extend in the same direction.

[0036] See also Figure 3As shown, in one embodiment, the second data line 31 is only correspondingly disposed in the second display area 3. A part of the second data line 31 extends from the first display area 2 to the bonding area and is connected to an external data driving chip. The second pixel unit 20 includes three second sub-pixels 21. In the second display area 3, two columns of the second sub-pixels 21 are disposed between two adjacent first data lines 30, and the second data line 31 is disposed between two adjacent first data lines 30; between two adjacent first data lines 30, one column of the two columns of the second sub-pixels 21 is connected to the first data line 30, and the other column is connected to the second data line 31.

[0037] Among them, the second sub-pixels 21 in the odd-numbered columns in the second display area 3 are respectively connected to a plurality of first data lines 30, and the second sub-pixels 21 in the even-numbered columns are respectively connected to a plurality of second data lines 31. In this solution, some of the second sub-pixels 21 are connected by borrowing some of the first data lines 30, and the other part is connected by using the newly added second data line 31.

[0038] Specifically, the first data line 30 and the second data line 31 are located in different layers, and on the substrate projection of the display panel 1, a part of the first data line 30 coincides with the second data line 31. Generally, the first data line 30 is disposed in the second metal layer of the display panel 1, that is, the metal layer where the source and drain are located in the display panel 1. In this embodiment, the second data line 31 can be selectively disposed in the third metal layer. The third metal layer is disposed above the second metal layer, and an insulating layer can be disposed therebetween for insulation. For a display panel 1 without a third metal layer of some specifications, a third metal layer can be disposed at a local position in the second display area 3 to be used as the second data line 31. The third metal layer of the display panel can be the same thickness as the first metal layer, about 4000 angstroms.

[0039] Of course, for the second data line 31 used less in this embodiment, the second data line 31 can be disposed in the second metal layer, specifically disposed between two adjacent first data lines 30, that is, between two columns of the second sub-pixels 21.

[0040] See Figure 4As shown, in another embodiment, within the second display area 3, multiple columns of the second sub-pixels 21 are arranged in one-to-one correspondence with multiple second data lines 31. Two columns of the second sub-pixels 21 are arranged between two adjacent first data lines 30. In this solution, the second sub-pixels 21 do not use the first data lines 30 at all. Instead, the number of second data lines 31 is twice that of the previous solution, so that within the second display area 3, each column of the second sub-pixels 21 is arranged corresponding to one second data line 31, and the data signals of this part are also provided by the data driving chip. However, in order to ensure the aperture, in this embodiment, two adjacent second data lines 31 are respectively arranged on both sides of a first data line 30. The first data line 30 and the second data line 31 are located in different layers, and on the substrate projection of the display panel 1, part of the first data line 30 coincides with the second data line 31, and the same light-shielding layer is used for light shielding.

[0041] In this application, even if the second pixel units 20 in the second display area 3 are increased, and the second sub-pixels 21 in the second pixel units 20 are different from the first sub-pixels 11 in the first pixel units 10, however, the second sub-pixels 21 and the first sub-pixels 11 can share the scanning lines, which will not be elaborated here.

[0042] Taking a common display screen as an example, generally, the size of the front camera is concentrated around 4 mm. Taking a 6-inch HD mobile phone display screen as an example, the size of a single sub-pixel is 34.5x103.5 um. Then, the number of the second sub-pixels 21 in the second display area 3 of the camera is about 110, that is, the area of 35 pixel units. When the pixel units at the camera are used for normal display, a curved display boundary will appear. For common irregular display boundaries, different aperture ratios are processed with a light-shielding layer to achieve gray-scale compensation and reduce display jaggedness. Such a processing method requires sufficient edge pixels for processing. When the number of our pixels is small, the number of gray-scale transitions is limited, the jagged elimination effect is not obvious, and at the same time, it will also occupy the aperture of the adjacent normal pixels. Therefore, if the pixel size at the camera is the same as that of the first display area 2, serious jaggedness will occur. After this application, the number of the second sub-pixels 21 in the second display area 3 can reach about 220, which is sufficient for gray-scale transition.

[0043] See Figure 5 As shown, Figure 5 is a schematic diagram of the display panel according to the second embodiment of the present application. Combining Figures 2-4, this application discloses another display panel 1. The display panel 1 includes a first display area 2 and a second display area 3. The second display area 3 includes a third transition area 4 and a fourth display area 5. The third transition area 4 surrounds the fourth display area 5. The bottom of the fourth display area 5 is used to install micro-components. The first display area 2 is provided with first pixel units 10, and the second pixel units 20 are provided in the third annular transition area. Among them, the area of each second pixel unit 20 is smaller than the area of each first pixel unit 10. The density of the first pixel units 10 in the first display area 2 is smaller than the density of the second pixel units 20 in the third transition area 4. It can be understood that the third transition area 4 is set within the display area, and the display panel 1 can also display in this area.

[0044] In this embodiment, a third transition area 4 is provided between the first display area 2 and the fourth display area 5. The second pixel units 20 are provided in this transition area, and the area of the sub-pixels in the second pixel units 20 is less than or equal to half of the area of the sub-pixels of the same color in the first pixel units 10. The density of the first pixel units 10 in the first display area 2 is less than or equal to half of the density of the second pixel units 20 in the second display area 3. By setting the transition area to form the boundary between the first display area 2 and the fourth display area 5, and using the second sub-pixels 21 in this transition area for gray-scale transition, it does not affect the design of the pixels in the fourth display area 5 and the first display area 2. Moreover, it makes the data of the sub-pixels unrestricted during gray-scale transition, and the transition is as smooth as possible, improving the boundary problem between the first display area 2 and the second display area 3 during display, and solving the problem of severe jaggedness at the edge during display at the camera position.

[0045] Specifically, the third transition area 4 is annular, and the fourth display area 5 is circular. The third transition area 4 is provided between the first display area 2 and the fourth display area 5. Generally speaking, the fourth display area 5 taking the camera as an example can be set as circular, that is, the fourth circular display area.

[0046] Specifically, the second pixel units 20 or the first pixel units 10 are provided in the fourth circular display area. The second pixel units 20 or the first pixel units 10 can be provided in the fourth circular display area. It can be specifically set according to the actual situation. If only the first pixel units 10 are provided in the fourth circular display area, then the pixel resolution of the fourth circular display area is made consistent with the pixel resolution of the first display area 2. Only in the transition area and the third transition area 4

[0047] In this embodiment, the display panel 1 includes a plurality of first data lines 30, a plurality of second data lines 31, and scan lines. The plurality of first data lines 30 provide data signals for the first pixel units 10, and the plurality of second data lines 31 provide data signals for the second pixel units 20. The extending directions of the first data lines 30 and the second data lines 31 are the same. The second pixel unit 20 includes a second red sub-pixel 22, a second green sub-pixel 23, and a second blue sub-pixel 24. In one second pixel unit 20, the second red sub-pixel 22, the second green sub-pixel 23, and the second blue sub-pixel 24 are arranged in a direction perpendicular to the data lines.

[0048] Among them, along the direction of the first data line 30, two adjacent second red sub-pixels 22, or second green sub-pixels 23, or second blue sub-pixels 24 are respectively a main area sub-pixel and a secondary area sub-pixel. In this solution, mainly when no transition is required in the transition area of the display panel 1, through the design of the main and secondary area pixels in the eight domains of two adjacent second pixel units 20, the area of a pixel point formed by two second pixel units 20 in the third transition area 4 is exactly equal to the area of a pixel point formed by one first pixel unit 10 in the first display area 2 and the fourth display area 5. That is, when no gray scale transition is required, the display in the third transition area is less different from that in the first display area 2 and the fourth display area 5.

[0049] Specifically, when the display panel 1 displays in the first state, the second pixel unit 20 displays normally. When the display panel 1 displays in the second state, the brightness of the second pixel unit 20 gradually decreases in the extending direction from the first display area 2 to the fourth display area 5. When the first display state is the normal display of the display panel 1, the camera is turned on at this time, the third transition area 4 displays a normal picture, while the fourth display area 5 does not display. At this time, by driving the main and secondary pixels of the second pixel unit 20 in the third transition area 4, the transition between the third transition area 4 and the first display area 2 is realized. In the second display state and when the fourth display area 5 is displayed and the camera is turned off, at this time, the third transition area 4 needs to undertake the gray scale transition function between the fourth display area 5 and the first display area 2.

[0050] Specifically, the second pixel unit 20 includes three second sub-pixels 21. In the second display area 3, two columns of the second sub-pixels 21 are arranged between two adjacent first data lines 30, and the second data line 31 is arranged between two adjacent first data lines 30. Between two adjacent first data lines 30, one column of the two columns of second sub-pixels 21 is connected to the first data line 30, and the other column is connected to the second data line 31.

[0051] Among them, the odd-column second sub-pixels 21 in the second display area 3 are respectively connected to a plurality of first data lines 30, and the even-column second sub-pixels 21 are respectively connected to a plurality of second data lines 31. In this solution, some of the second sub-pixels 21 are connected by borrowing some of the first data lines 30, and the other part is connected by using the newly added second data lines 31. In this embodiment, the second data lines 31 can be arranged in the second metal layer, specifically arranged between two adjacent first data lines 30, that is, between two columns of second sub-pixels 21, and arranged at intervals from the first data lines 30.

[0052] In another embodiment, the second pixel unit 20 includes three second sub-pixels 21. In the second display area 3, multiple columns of the second sub-pixels 21 are arranged in one-to-one correspondence with multiple second data lines 31, and two columns of the second sub-pixels 21 are arranged between two adjacent first data lines 30; the first data lines 30 and the second data lines 31 are located in different layers, and in the substrate projection of the display panel 1, some of the first data lines 30 coincide with the second data lines 31. In this solution, the second sub-pixels 21 do not use the first data lines 30 at all, but set twice as many second data lines 31 as in the previous solution, so that in the second display area 3, each column of second sub-pixels 21 is arranged corresponding to one second data line 31, and the data signals of this part are also provided by the data driving chip. However, in order to ensure the aperture, in this embodiment, two adjacent second data lines 31 are respectively arranged on both sides of a first data line 30. The first data lines 30 and the second data lines 31 are located in different layers, and in the substrate projection of the display panel 1, some of the first data lines 30 coincide with the second data lines 31, and the same light-shielding layer is used for light shielding. And in this solution, two adjacent second data lines 31 can adopt the Dmux design scheme, that is, a one-to-two method, which can reduce the number of source signal channels and save costs.

[0053] It should be understood that for the second display area 3, the problem of transmitting light for the camera does not need to be considered. The specific method is to set a light barrier layer on the display panel 1. The optical cable layer is arranged on the side of the display panel 1 and wraps the display panel 1. A part of the light barrier layer arranged on the display panel 1 collects light and transmits it to the camera arranged at the bottom of the display panel 1. Specifically, when the camera is started, the light barrier layer is in a light-transmitting state, and the light of each light barrier layer is sequentially transmitted to the camera through the light transmission layer in the light barrier layer. The light sequentially acquired by the camera is synthesized into a target image.

[0054] See Figure 6As shown, in another embodiment, the fourth circular display area may also be set as the third pixel unit 40. The sub-pixels of the third pixel unit 40 are half of those of the first pixel unit sub-pixels, and the density of the sub-pixels of the third pixel unit 40 per unit area is the same as that of the first pixel unit sub-pixels. That is, the area of the sub-pixels of the third pixel unit 40 is reduced, but the reduced area is no longer filled with new sub-pixels, thereby forming a transparent area for light transmission. In this solution, the light intake of the camera can be improved.

[0055] See Figure 7 As shown, the present application also discloses a display device. The display device 50 includes a driving circuit 51 and the above-mentioned display panel 1. Under the design of this patent, the number of sub-pixels in the camera area can be doubled, the pixel resolution at the camera can be increased, the disadvantage of poor image quality of a conventional under-screen camera can be compensated, and at the same time, the number of pixels available for gray-scale compensation is increased, the jagged feeling in the display area can be weakened, and the picture quality is not sacrificed.

[0056] It should be noted that the inventive concept of the present application can form a very large number of embodiments. However, due to the limited space of the application documents, it is impossible to list them all. Therefore, on the premise of no conflict, the above-described embodiments or technical features can be combined arbitrarily to form new embodiments. After the combination of each embodiment or technical feature, the original technical effect will be enhanced.

[0057] The above content is a further detailed description of the present application in combination with specific optional implementation manners. It cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present application.
