Fig. 1 is a schematic diagram of a display panel according to a first embodiment of the present invention, and the display panel 100 of the present embodiment may be an Organic Light-Emitting Diode (OLED) display panel 100, which includes a first display area 100a and a second display area 100b, and in some embodiments, further includes a non-display area. Wherein the second display area 100b may be used for integration of light sensitive elements such as cameras, infrared sensors, structured light sensors, etc.
Fig. 2a and 2b are partially enlarged schematic views illustrating a first display area 100a of the display panel 100 according to the first embodiment of the invention, where the first display area 100a includes a plurality of first repeating units 110a arranged in an array, and in fig. 2a, one of the first repeating units 110a in the first display area 100a is shown by a thick dotted line.
Fig. 3a and 3b are partially enlarged schematic views illustrating a second display area 100b of the display panel 100 according to the first embodiment of the present invention, the second display area 100b includes a plurality of second repeating units 110b arranged in an array, and in fig. 3a, one of the second repeating units 110b in the second display area 100b is illustrated by a thick dotted line.

The sub-pixel density of the second display area 100b is less than that of the first display area 100a, and the second repeating unit 110b has the same contour shape as the first repeating unit 110 a.
According to the display panel 100 of the embodiment of the invention, the sub-pixel density of the second display area 100b is less than that of the first display area 100a, so that the first display area 100a can maintain a high pixel density value, the fineness of a display picture is ensured, and the pixel density of the second display area 100b is relatively reduced, thereby reducing array routing in the second display area 100b, reducing diffraction phenomenon of the routing to incident light, facilitating integration of a photosensitive module at the second display area 100b, reducing non-display areas of the display panel 100, and improving the display effect of the display panel 100.
The second repeating unit 110b has the same contour shape as the first repeating unit 110a, so that the sub-pixels 190 in the first display area 100a and the sub-pixels 190 in the second display area 100b can be formed using the same mask, reducing the design cost.
The sub-pixel 190, i.e., the light emitting element, may be formed by forming a limited opening in a Pixel Definition (PDL) layer of the display panel 100, and then forming the sub-pixel 190 by evaporation in the opening. By controlling the number of openings or the opening ratio on the pixel defining layer, control of the pixel density can be achieved.
It should be noted that fig. 1 only shows an example of the first display area 100a and the second display area 100b, the display panel 100 is rectangular, the second display area 100b is located in an inner area of the display panel 100, an outer contour of the first display area 100a is rectangular, the second display area 100b is circular, and in other embodiments, shapes of the first display area 100a and the second display area 100b may not be limited to the above example. Fig. 4, 5, and 6 are schematic diagrams illustrating display panels of three alternative embodiments, which will be described below.
In the display panel 100 of the second embodiment shown in fig. 4, the display panel 100 is rectangular, the second display area 100b is semi-elliptical, the second display area 100b is disposed corresponding to the middle of the short side of the rectangle of the display panel 100, and the remaining other display areas are the first display area 100a, wherein the sub-pixel density of the second display area 100b is less than that of the first display area 100 a.

In the display panel 100 of the fourth embodiment shown in fig. 6, the display panel 100 has a rectangular shape, and the second display area 100b has a special-shaped shape, for example, a special-shaped rectangle, in which one side of the rectangle is replaced by an outwardly convex arc. The second display area 100b is disposed corresponding to the middle of the short side of the rectangle of the display panel 100, wherein the side opposite to the arc side of the special-shaped rectangle is overlapped with the short side of the rectangle of the display panel 100, the remaining other display areas are the first display area 100a, and the sub-pixel density of the second display area 100b is less than that of the first display area 100 a.

When the photosensitive elements are integrated with the display panel 100 of the embodiment of the present invention, the display driving of the first display area 100a and the second display area 100b of the display panel 100 can be adjusted accordingly.
For example, the display panel 100 of the embodiment of the present invention is used for displaying a front panel of a mobile phone, and the photosensitive element is, for example, a front camera on the front of the mobile phone. The front camera may be integrated below the thickness direction of the second display area 100b of the display panel 100 (i.e., integrated below the screen of the display screen). When the front camera is not turned on, the first display area 100a and the second display area 100b of the display panel 100 display normally; when the front camera is turned on to perform image acquisition, the first display area 100a of the display panel 100 displays normally, and the second display area 100b displays in a pause manner, so that the interference to the image acquisition of the front camera is avoided.
The detailed description of the display panel 100 according to the first embodiment of the present invention will be continued.
As shown in fig. 2a, each of the first repeating units 110a according to the first embodiment of the present invention includes a first sub-pixel group 111a, a second sub-pixel group 112a, and a third sub-pixel group 113a respectively displaying different colors. As shown in fig. 3a, each of the second repeating units 110b of the present embodiment includes a fourth sub-pixel group 111b displaying the same color as the first sub-pixel group 111a, a fifth sub-pixel group 112b displaying the same color as the second sub-pixel group 112a, and a sixth sub-pixel group 113b displaying the same color as the third sub-pixel group 113 a. In the present embodiment, the fourth sub-pixel group 111b, the fifth sub-pixel group 112b, and the sixth sub-pixel group 113b are arranged in the second repeating unit 110b in the same manner as the first sub-pixel group 111a, the second sub-pixel group 112a, and the third sub-pixel group 113a are arranged in the first repeating unit 110 a.
According to the above structure, the arrangement of the sub-pixel groups of each color in the second repeating unit 110b is the same as the arrangement of the sub-pixel groups of each color in the first repeating unit 110a, so that the sub-pixels 190 in the first display area 100a and the sub-pixels 190 in the second display area 100b can be formed by using the same mask plate only by requiring different opening designs of the pixel defining layer, thereby reducing the design cost.
In this embodiment, the first sub-pixel group 111a and the fourth sub-pixel group 111b display red, the second sub-pixel group 112a and the fifth sub-pixel group 112b display blue, and the third sub-pixel group 113a and the sixth sub-pixel group 113b display green.
The plurality of sub-pixels 190 may include a first sub-pixel 191, a second sub-pixel 192, and a third sub-pixel 193 that display different colors, wherein in the present embodiment, the first sub-pixel 191 displays red, for example, the second sub-pixel 192 displays blue, for example, and the third sub-pixel 193 displays green, for example.
Therefore, in the present embodiment, the first subpixel group 111a may include more than two first subpixels 191, the second subpixel group 112a may include more than two second subpixels 192, and the third subpixel group 113a may include more than two third subpixels 193; the fourth subpixel group 111b may include at least one first subpixel 191, the fifth subpixel group 112b may include at least one second subpixel 192, and the sixth subpixel group 113b may include at least one third subpixel 193.
It is to be understood that the display color of each of the plurality of sub-pixel groups and the color of each of the plurality of sub-pixels 190 are merely examples, and in other embodiments, other colors may be displayed and other corresponding combinations may be formed.
In this embodiment, the ratio of the number of sub-pixels 190 (i.e., first sub-pixels 191) in the first sub-pixel group 111a, the number of sub-pixels 190 (i.e., second sub-pixels 192) in the second sub-pixel group 112a, and the number of sub-pixels 190 (i.e., third sub-pixels 193) in the third sub-pixel group 113a is the same as the ratio of the number of sub-pixels 190 (i.e., first sub-pixels 191) in the fourth sub-pixel group 111b, the number of sub-pixels 190 (i.e., second sub-pixels 192) in the fifth sub-pixel group 112b, and the number of sub-pixels 190 (i.e., third sub-pixels 193) in the sixth sub-pixel group 113 b.
In some embodiments, the ratio of the number of sub-pixels 190 in first sub-pixel group 111a, the number of sub-pixels 190 in second sub-pixel group 112a, and the number of sub-pixels 190 in third sub-pixel group 113a may be 1: 2. Accordingly, the ratio of the number of sub-pixels 190 in the fourth sub-pixel group 111b, the number of sub-pixels 190 in the fifth sub-pixel group 112b, and the number of sub-pixels 190 in the sixth sub-pixel group 113b is also 1: 2. Specifically, in the present embodiment, in each first sub-pixel group 111a and each second sub-pixel group 112a, the first sub-pixel 191 displaying red, the second sub-pixel 192 displaying blue, and the third sub-pixel 193 displaying green are 1: 2.
According to the above-mentioned proportional arrangement of the sub-pixels 190 of each color in the first repeating unit 110a and the second repeating unit 110b, it is beneficial to increase the pixel density of the display panel 100 and improve the fineness of the display.
The number of sub-pixels 190 in the fourth sub-pixel group 111b is smaller than the number of sub-pixels 190 in the first sub-pixel group 111 a. Correspondingly, the number of sub-pixels 190 in the fifth sub-pixel group 112b is smaller than the number of sub-pixels 190 in the second sub-pixel group 112a, and the number of sub-pixels 190 in the sixth sub-pixel group 113b is smaller than the number of sub-pixels 190 in the third sub-pixel group 113a, so that the sub-pixel density of the second display area 100b is smaller than that of the first display area 100 a.
In some embodiments, the number of subpixels 190 in fourth subpixel group 111b is 1/2 the number of subpixels 190 in first subpixel group 111 a. For example, in the present embodiment, the first subpixel group 111a includes two first subpixels 191, and the fourth subpixel group 111b includes one first subpixel 191. Accordingly, the second sub-pixel group 112a includes two second sub-pixels 192, and the fifth sub-pixel group 112b includes one second sub-pixel 192; the third subpixel group 113a includes four third subpixels 193, and the sixth subpixel group 113b includes two third subpixels 193.
It is understood that the number of the sub-pixels 190 included in each sub-pixel group is only an example, and other number distributions are possible in other embodiments. The ratio of the number of sub-pixels 190 in the fourth sub-pixel group 111b to the number of sub-pixels 190 in the first sub-pixel group 111a is not limited to 1/2, and may be 1/3, 1/4, or the like.
In this embodiment, the first repeating unit 110a has two columns, the first sub-pixel group 111a and the second sub-pixel group 112a are sequentially arranged in one of the two columns, and the third sub-pixel group 113a is located in the other of the two columns. The second repeating unit 110b of the present embodiment also has two columns, the fourth sub-pixel group 111b and the fifth sub-pixel group 112b are sequentially arranged in one of the two columns, and the sixth sub-pixel group 113b is located in the other of the two columns.
In this embodiment, the sub-pixels 190 included in each sub-pixel group may be arranged in a sequential direction, for example, in this embodiment, the two first sub-pixels 191 included in the first sub-pixel group 111a are arranged in a column direction, the four third sub-pixels 193 included in the third sub-pixel group 113a are arranged in a column direction, and the two third sub-pixels 193 included in the sixth sub-pixel group 113b are arranged in a column direction. In other embodiments, the sub-pixels 190 included in each sub-pixel group may be arranged in other suitable manners.
According to the display panel 100 of the embodiment of the invention, the first display area 100a has a plurality of first pixel units 120a therein, and in fig. 2b, two adjacent first pixel units 120a in the first display area 100a are shown by thick dashed lines.
The second display area 100b has a plurality of second pixel units 120b therein, and in fig. 3b, one of the second pixel units 120b in the second display area 100b is shown by a thick dotted line.
In this embodiment, each of the first pixel unit 120a and the second pixel unit 120b includes a first subpixel 191, a second subpixel 192, and two third subpixels 193.
In some embodiments, the total area of any color sub-pixels 190 within the second pixel unit 120b is greater than the total area of the same color sub-pixels 190 within the first pixel unit 120 a. Specifically, in the present embodiment, the area of the first subpixel 191 displaying red in the second pixel unit 120b is larger than the area of the first subpixel 191 in the first pixel unit 120 a; the area of the second sub-pixel 192 displaying blue in the second pixel unit 120b is larger than the area of the second sub-pixel 192 in the first pixel unit 120 a; the total area of the two third sub-pixels 193 displaying green in the second pixel unit 120b is larger than the total area of the two third sub-pixels 193 in the first pixel unit 120 a. According to the above-mentioned total area correspondence relationship of the sub-pixels 190, the uniformity of the display of the first display area 100a and the second display area 100b is improved.

According to the display device of the embodiment of the invention, the sub-pixel density of the second display area 100b is less than that of the first display area 100a, so that the first display area 100a can keep high pixel density, the fineness of a display picture is ensured, and the pixel density of the second display area 100b is reduced, thereby reducing array wiring in the second display area 100b, reducing diffraction phenomenon of the wiring to incident light, facilitating integration of the photosensitive module 900 at the second display area 100b, reducing non-display areas of the display panel 100, and improving the display effect of the display panel 100.
The second repeating unit 110b has the same contour shape as the first repeating unit 110a, so that the light emitting elements in the first display area 100a and the light emitting elements in the second display area 100b can be formed by using the same mask plate, thereby reducing the design cost.
As shown in fig. 7, the display panel 100 may include a common wire 130 connected to the plurality of sub-pixels 190, in the second display area 100b, the common wire 130 bypasses from the periphery of the projection profile of the photosensitive module 900 on the second display area 100b, so that the common wire 130 can avoid the path of the incident light that needs to enter the photosensitive module 900, thereby avoiding diffraction of the common wire 130 to the incident light, solving the problem of display defects after the photosensitive module 900 is integrated under the display panel 100, thereby avoiding the display panel 100 from reserving a non-display area corresponding to the photosensitive module 900, and improving the screen ratio of the display device.
The common line 130 may be, for example, a scan line, a power line, or the like that can be connected to a pixel circuit of each sub-pixel 190 in an Active matrix organic light-emitting diode (AMOLED) display panel, or may be any one common electrode in a Passive matrix organic light-emitting diode (PMOLED) display panel as long as it is a wire connected to at most sub-pixels 190.
