Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a display panel according to the present application, where the display panel may be an OLED display panel, a Micro-LED display panel, and the like, and may be applied to a display device such as a mobile phone and a flat panel, the display panel includes a main display area 10 and an auxiliary display area 12 disposed adjacent to the main display area 10, and the auxiliary display area 12 may be a rectangle, a rounded rectangle, or an irregular shape. The design mode can ensure that the auxiliary display area 12 has a higher transmittance while having a display function, so that the auxiliary display area 12 does not influence the performance of subsequent optical modules (such as a camera module, a fingerprint identification module and the like) correspondingly arranged at the position; the sub-pixels in the boundary area 14 of the main display area 10 and the sub-pixels in the sub-display area 12 in the same boundary area 14 cooperate with each other to form a plurality of pixel units 16, each pixel unit 16 includes a first sub-pixel 160, a second sub-pixel 162, and a third sub-pixel 164, which are different in color, respectively, and one of the first sub-pixel 160, the second sub-pixel 162, and the third sub-pixel 164 may be a red sub-pixel, one may be a green sub-pixel, and the other may be a blue sub-pixel. Preferably, in the present embodiment, the first sub-pixel 160 is a red sub-pixel, the second sub-pixel 162 is a blue sub-pixel, and the third sub-pixel 164 is a green sub-pixel.
The first sub-pixel 160, the second sub-pixel 162 and the third sub-pixel 164 in each pixel unit 16 in the interface region 14 can emit light in combination under the driving action, for example, emit white light in combination, so as to reduce the phenomenon of color boundary of the interface region 14 between the main display region 10 and the sub-display region 12 and improve the display visual effect.
In this embodiment, as shown in fig. 1, three boundary regions 14 may be formed at the boundary positions of the main display region 10 and the sub display region 12. In other embodiments, the main display area 10 and the secondary display area 12 may also form more or fewer interface areas 14. As shown in fig. 2, the boundary position of the main display area 10a and the sub display area 12a may form four boundary areas 14a. Alternatively, as shown in fig. 3, the sub display area 12b is located at one corner of the main display area 10b, and two boundary areas 14b are formed at the boundary position between the sub display area 10b and the main display area 12 b.
In one embodiment, with continued reference to fig. 1, the sub-pixels in the boundary region 14 of one of the main display region 10 and the sub-display region 12 are alternately arranged as a first sub-pixel 160 and a second sub-pixel 162; the sub-pixel in the boundary area 14 of the other of the main display area 10 and the sub-display area 12 is the third sub-pixel 164 arranged in sequence. The arrangement mode of the sub-pixels has a simple structure and is convenient to manufacture. Preferably, in the present embodiment, the middle interval position of at least partially adjacent two first sub-pixels 160 and second sub-pixels 162 corresponds to the position of the third sub-pixel 164.
In an application scenario, as shown in fig. 1, every two adjacent first sub-pixels 160 and second sub-pixels 162 in the boundary region 14 are respectively disposed adjacent to one third sub-pixel 164 to form one pixel unit 16, and the first sub-pixels 160 and the second sub-pixels 162 are respectively shared by the two adjacent pixel units 16 (as shown by the solid triangles in fig. 1). The arrangement structure of the sub-pixels is simple in design, the density of the sub-pixels is high, and the display effect is fine; in addition, when the sub-pixel arrangement structure is manufactured by using a mask, the design margin between adjacent sub-pixels is sufficient, and the phenomenon of a vacant pixel does not occur, so that the jaggy feeling of the junction area 14 is weakened.
Alternatively, as shown in fig. 1, two adjacent first sub-pixels 160 and second sub-pixels 162 in the boundary region 14 are respectively disposed adjacent to one third sub-pixel 164 to form one pixel unit 16, and the two adjacent pixel units 16 are in the form of non-shared pixels (as shown by the dashed triangles in fig. 1). The sub-pixel arrangement structure is simple in design and simple in driving mode.
In yet another application scenario, as shown in FIG. 1, the at least one interface area 14 includes a first interface area 140 and a second interface area 142 disposed opposite each other. The sub-pixels of the main display area 10 in the first interface area 140 are the first sub-pixels 160 and the second sub-pixels 162 that are alternately arranged, and the sub-pixels of the sub-display area 12 in the first interface area 140 are the third sub-pixels 164 that are sequentially arranged. The sub-pixels of the main display area 10 in the second interface area 142 are the third sub-pixels 164 arranged in sequence, and the sub-pixels of the sub-display area 12 in the second interface area 142 are the first sub-pixels 160 and the second sub-pixels 162 arranged alternately. Each two of the first sub-pixels 160 and the second sub-pixels 162 adjacent to each other at least in part in the first interface region 140 or the second interface region 142 may be adjacent to one of the third sub-pixels 164, and the pixel units 16 in the first interface region 140 or the second interface region 142 may be in a sub-pixel shared or non-shared form, which is not limited in this application. The arrangement of the sub-pixels in the first boundary area 140 and the second boundary area 142 is simple and is beneficial to the subsequent routing. Of course, in other embodiments, the same sub-pixel arrangement may be adopted in the first boundary area 140 and the second boundary area 142, which is not limited in this application.
Further, with reference to fig. 1, the at least one junction area 14 further includes a third junction area 144 connecting the first junction area 140 and the second junction area 142, the sub-pixels of the main display area 10 in the third junction area 144 are alternately arranged as first sub-pixels 160 and second sub-pixels 162, and the sub-pixels of the sub-display area 12 in the third junction area 144 are sequentially arranged as third sub-pixels 164. The sub-pixel arrangement structure is simple and is beneficial to subsequent wiring.
Further, with reference to fig. 1, the sub-display area 12 further includes a second boundary 122 disposed flush with a first boundary (not labeled) of the main display area 10, and the sub-pixels on the first boundary and the second boundary 122 are a first sub-pixel 160 and a second sub-pixel 162 that are alternately arranged. The arrangement of the sub-pixels is simple, and the first sub-pixel 160 and the second sub-pixel 162 on the first boundary and the second boundary 122 can mix to emit colors insensitive to human eyes, thereby weakening the color fringing phenomenon of the first boundary and the second boundary 122. Preferably, in the present embodiment, the first sub-pixel 160 is a red sub-pixel, the second sub-pixel 162 is a blue sub-pixel, and the red sub-pixel and the blue sub-pixel can be mixed to form a purple color, so that the color-edge effect on the first boundary and the second boundary 122 can be weakened because the human eye is not sensitive to the purple color.
In another embodiment, referring to fig. 1 again, in the main display area 10 or the sub-display area 12, the first sub-pixels 160 and the second sub-pixels 162 are disposed in the same row or the same column and are alternately arranged along the row direction or the column direction, and the third sub-pixels 164 are disposed between the first sub-pixels 160 and the second sub-pixels 162 alternately arranged in two adjacent rows or two adjacent columns and are sequentially arranged along the row direction and/or the column direction. The arrangement structure of the sub-pixels on the display panel is simple, and the process preparation process is simple.
For example, the ith pixel row in the main display area 10 or the sub-display area 12 adopts a spaced arrangement of the first sub-pixels 160 and the second sub-pixels 162, the (i + 1) th pixel row adopts a sequential arrangement of a plurality of the third sub-pixels 164, and the position between every two adjacent first sub-pixels 160 and second sub-pixels 162 of the ith pixel row corresponds to the position of one third sub-pixel 164 of the (i + 1) th pixel row. The jth pixel column of the main display area 10 or the sub-display area 12 adopts a spaced arrangement manner of the first sub-pixels 160 and the second sub-pixels 162, the jth +1 pixel column adopts a sequential arrangement manner of a plurality of third sub-pixels 164, and the position between every two adjacent first sub-pixels 160 and second sub-pixels 162 of the jth pixel column corresponds to the position of one third sub-pixel 164 of the jth +1 pixel column. The pixel density of the sub-pixel arrangement structure on the display panel is large, so that the display effect is fine and smooth. Further, the pixel rows in the sub display area 12 are flush with the pixel rows of the main display area 10, and the pixel columns in the sub display area 12 may be flush with the pixel columns in the main display area 10.
In addition, as shown in fig. 1, the first sub-pixels 160 and the second sub-pixels 162 may be arranged at intervals for the pixel rows or the pixel columns of the main display area 10 and the sub-display area 12, which are located at the edge of the display panel. The first sub-pixel 160 and the second sub-pixel 162 at the edge can mix to emit colors insensitive to human eyes, thereby reducing the color fringing problem at the edge of the display panel. Preferably, in the present embodiment, the first sub-pixel 160 is a red sub-pixel, the second sub-pixel 162 is a blue sub-pixel, and the red sub-pixel and the blue sub-pixel can be mixed to form a purple color, so that the color fringe effect at the edge of the display panel can be weakened because the human eye is not sensitive to the purple color.
In another embodiment, referring to fig. 1 again, in the row direction or the column direction, a distance d1 between two adjacent sub-pixels of the sub-display area 12 is greater than a distance d2 between two adjacent sub-pixels of the main display area 10. The design method can make the sub-pixel density of the sub-display area 12 smaller than that of the main display area 10, so that the sub-display area 12 has a display function and a high transmittance, and the normal use of the optical module located in the sub-display area 12 subsequently cannot be influenced.
Preferably, a distance d1 between adjacent two sub-pixels positioned in the sub display area 12 is twice a distance d2 between adjacent two sub-pixels positioned in the main display area 10 in a row direction or a column direction. The design is to balance the optimal results obtained in both transmission and sub-pixel density.
In another embodiment, referring to fig. 1 again, each of the first sub-pixel 160, the second sub-pixel 162 and the third sub-pixel 164 in the display panel includes an active light emitting area 166 and an inactive light emitting area 168 located at the periphery of the active light emitting area 166. The active light-emitting area 166 may be an area where a light-emitting layer of the OLED device is located, and the inactive light-emitting area 168 may be an area where a pixel defining layer of the OLED device is located, corresponding to a physical structure.
The active light emitting area 166 of the first sub-pixel 160, the second sub-pixel 162, and the third sub-pixel 164 in the main display area 10 is a diamond shape, and the inactive light emitting area 168 is a diamond shape; the diamond design can make the sub-pixels in the main display area 10 more closely arranged, the density of the sub-pixels is higher, and the display effect is more fine.
And/or the effective light emitting areas 166 of the first sub-pixel 160 and/or the second sub-pixel 162 and/or the third sub-pixel 164 in the sub-display area 12 are circular or elliptical, and the ineffective light emitting areas 168 are diamond-shaped or hexagonal. The diamond or hexagonal design can make the arrangement between the sub-pixels in the sub-display region 12 and the sub-pixels in the adjacent main display region 10 more compact; the circular or elliptical shape of the effective light emitting region 166 is beneficial to reducing diffraction, reducing the distance between the effective light emitting region and the surrounding sub-pixels, and weakening the display jaggy feeling of the junction region 14; in addition, the circular or elliptical design of the active light emitting region 166 allows for a larger design margin between the active light emitting region 166 and the peripheral inactive light emitting region 168, which facilitates process fabrication and results in a higher yield.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
