However, the current dual-picture display device can only allow the user to see the display picture on the left and right sides, and if the user is located in the middle of the display screen, the display picture cannot be seen.

Moreover, due to the angle limitation between the second picture display pixel and the black matrix, the visual angle range of the second picture display pixel includes the side edge and the middle position, and when a user stands at the middle position, the second picture can also be seen. Therefore, the technical scheme provided in the embodiments of the present application can realize that the user can watch the display picture in the left, middle and right directions.

[0026] The application will be described in detail below with reference to the drawings.

[0027] Figure 1 A schematic structural diagram of a display panel is provided in the application.

[0028] As shown in Figure 1 , the display panel 10 includes a substrate substrate 11, a pixel layer 12 and a viewing angle definition layer 13 which are sequentially stacked along a first direction.

[0029] In the application, the first direction refers to the thickness direction of the display substrate 10, such as Figure 1 the x direction shown in the figure.

[0030] It should be understood that the x direction is only an exemplary description of the first direction, and does not constitute a limitation on the first direction of the application. For the sake of convenience, the first direction is described as the x direction below.

[0031] Specifically, as shown in Figure 1 , the pixel layer 12 includes a plurality of sub-pixel groups 121 arranged along a second direction, and one sub-pixel group 121 includes a first picture display pixel 1211 and a second picture display pixel 1212 arranged along the second direction. The second direction is perpendicular to the x direction, for example, the second direction is the y direction as shown in Figure 1 .

[0032] It should be understood that the y direction is only an exemplary description of the second direction, and does not constitute a limitation on the second direction of the application. For the sake of convenience, the second direction is described as the y direction below.

[0033] In the application, the first picture display pixel 1211 of each sub-pixel group 121 is used as a first sub-pixel group to display a first picture, and the second picture display pixel 1212 of each sub-pixel group 121 is used as a second sub-pixel group to display a second picture.

[0034] The viewing angle definition layer 13 includes a plurality of color films 131 and a plurality of black matrices 132 arranged along the y direction, and one black matrix 132 is arranged between two adjacent color films 131. The viewing angle definition layer 13 can define the visible angle range of the first sub-pixel group and the visible angle range of the second sub-pixel group.

[0035] Specifically, along the x direction, one color film 131 is arranged opposite to one second picture display pixel 1212, and the orthogonal projection of the color film 131 on the substrate substrate 11 covers the orthogonal projection of the second picture display pixel 1212 on the substrate substrate 11. One black matrix 132 is arranged opposite to one first picture display pixel 1211, and the orthogonal projection of the black matrix 132 on the substrate substrate 11 covers the orthogonal projection of the first picture display pixel 1211 on the substrate substrate 11.

[0036] With reference to the above Figure 1 In the x direction, the first picture display pixel 1211 includes a first side edge m close to the black matrix 132, and in the y direction, the first side edge m is away from the endpoint of the second picture display pixel 1212, which is marked as point A; in the y direction, the black matrix 132 includes a second side edge n away from the second picture display pixel 1212, and in the x direction, the second side edge n is close to the endpoint of the first picture display pixel 1211, which is marked as point B; the angle between the line segment AB and the y direction (the direction indicated by the arrow) is α.

[0037] In the x direction, the second picture display pixel 1212 includes a third side edge j close to the color film 131, and in the y direction, the third side edge j is away from the endpoint of the first picture display pixel 1211, which is marked as point C; in the y direction, the black matrix 132 includes a fourth side edge k close to the second picture display pixel 1212, and in the x direction, the fourth side edge k is away from the endpoint of the second picture display pixel 1212, which is marked as point D; the angle between the line segment CD and the y direction (the direction indicated by the arrow) is β.

[0038] Wherein, β > α, and both α and β are acute angles.

[0039] In the embodiment of the present application, in the thickness direction of the substrate 11, the first picture display pixel 1211 is arranged opposite to the black matrix 132, and the orthogonal projection of the black matrix 132 on the substrate 11 covers the orthogonal projection of the first picture display pixel 1211 on the substrate 11; the second picture display pixel 1212 is arranged opposite to the color film 131, and the orthogonal projection of the color film 131 on the substrate 11 covers the orthogonal projection of the second picture display pixel 1212 on the substrate 11. Further, the positional relationship between the first picture display pixel 1211 and the second picture display pixel 1212 and the black matrix 132 is designed, that is, the angle α between the line segment AB and the second direction and the angle β between the line segment CD and the second direction satisfy: β > α, and both α and β are acute angles, so that the visual angle range of the first picture display pixel 1211 and the visual angle range of the second picture display pixel 1212 do not overlap, thereby avoiding seeing the superimposed display picture of the first picture and the second picture at the same angle, and avoiding affecting the viewing experience. Moreover, due to the above angle limitation between the second picture display pixel 1212 and the black matrix 132, the visual angle range of the second picture display pixel 1212 includes the side edge and the middle position, and when the user stands at the middle position, the second picture can also be seen. Therefore, the technical scheme provided by the embodiment of the present application can realize that the user can watch the display picture in the left, middle and right directions.

[0040] In some embodiments, the first picture display pixel 1211 and the second picture display pixel 1212 in the sub-pixel group 121 can emit light at the same time or can not emit light at the same time. For example, the first picture display pixel 1211 and the second picture display pixel 1212 can emit light alternately.

[0041] In some embodiments, as shown in Figure 1 The plurality of sub-pixel groups 121 includes a first sub-pixel group 121a, a second sub-pixel group 121b, and a third sub-pixel group 121c, wherein the first sub-pixel group 121a includes a first sub-pixel 1211a and a second sub-pixel 1212a, the second sub-pixel group 121b includes a third sub-pixel 1211b and a fourth sub-pixel 1212b, and the third sub-pixel group 121c includes a fifth sub-pixel 1211c and a sixth sub-pixel 1212c; the first sub-pixel 1211a, the second sub-pixel 1212a, the third sub-pixel 1211b, the fourth sub-pixel 1212b, the fifth sub-pixel 1211c, and the sixth sub-pixel 1212c are arranged in sequence along the y direction.

[0042] The first sub-pixel 1211a, the third sub-pixel 1211b, and the fifth sub-pixel 1211c are all first picture display pixels 1211, and the second sub-pixel 1212a, the fourth sub-pixel 1212b, and the sixth sub-pixel 1212c are all second picture display pixels 1212.

[0043] It should be understood that in OLED display technology, a pixel includes at least a red pixel (R pixel), a green pixel (G pixel), and a blue pixel (B pixel), so the display of a first picture requires first picture display pixels 1211 of three different colors (red, green, and blue), and similarly, the display of a second picture requires second picture display pixels 1212 of three different colors (red, green, and blue). Exemplarily, in the embodiments of the present application, a plurality of sub-pixel groups 121 includes a first sub-pixel 1211a group 121a, a second sub-pixel 1212a, and a third sub-pixel 1211b are exemplarily described.

[0044] Correspondingly, continuing to refer to Figure 1 The plurality of color filters 131 includes a first color filter 131a, a second color filter 131b, and a third color filter 131c arranged at intervals along the y direction, and the plurality of black matrices 132 includes a first black matrix 132a, a second black matrix 132b, and a third black matrix 132c arranged at intervals along the y direction; wherein the first black matrix 132a, the first color filter 131a, the second black matrix 132b, the second color filter 131b, the third black matrix 132c, and the third color filter 131c are arranged in sequence along the y direction.

[0045] As shown in Figure 1As shown, in the x direction, the first black matrix 132a is arranged opposite to the first sub-pixel 1211a, and the orthographic projection of the first black matrix 132a on the substrate 11 covers the orthographic projection of the first sub-pixel 1211a on the substrate 11; the first color film 131a is arranged opposite to the second sub-pixel 1212a, and the orthographic projection of the first color film 131a on the substrate 11 covers the orthographic projection of the second sub-pixel 1212a on the substrate 11; the second black matrix 132b is arranged opposite to the third sub-pixel 1211b, and the orthographic projection of the second black matrix 132b on the substrate 11 covers the orthographic projection of the third sub-pixel 1211b on the substrate 11; the second color film 131b is arranged opposite to the fourth sub-pixel 1212b, and the orthographic projection of the second color film 131b on the substrate 11 covers the orthographic projection of the fourth sub-pixel 1212b on the substrate 11; the third black matrix 132c is arranged opposite to the fifth sub-pixel 1211c, and the orthographic projection of the third black matrix 132c on the substrate 11 covers the orthographic projection of the fifth sub-pixel 1211c on the substrate 11; the third color film 131c is arranged opposite to the sixth sub-pixel 1212c, and the orthographic projection of the third color film 131c on the substrate 11 covers the orthographic projection of the sixth sub-pixel 1212c on the substrate 11.

[0046] In some embodiments, the first sub-pixel 1211a, the third sub-pixel 1211b and the fifth sub-pixel 1211c are red pixels, green pixels or blue pixels respectively, and the pixel colors of the first sub-pixel 1211a, the third sub-pixel 1211b and the fifth sub-pixel 1211c are different; the second sub-pixel 1212a, the fourth sub-pixel 1212b and the sixth sub-pixel 1212c are red pixels, green pixels or blue pixels respectively, and the pixel colors of the second sub-pixel 1212a, the fourth sub-pixel 1212b and the sixth sub-pixel 1212c are different.

[0047] In the embodiments of the present application, the first sub-pixel 1211a, the third sub-pixel 1211b and the fifth sub-pixel 1211c are all first picture display pixels 1211. In order to realize full-color display of the first picture, the first sub-pixel 1211a, the third sub-pixel 1211b and the fifth sub-pixel 1211c are respectively red pixels, green pixels or blue pixels, and the pixel colors of the first sub-pixel 1211a, the third sub-pixel 1211b and the fifth sub-pixel 1211c are different. That is, one of the first sub-pixel 1211a, the third sub-pixel 1211b and the fifth sub-pixel 1211c is an R pixel, one is a G pixel, and one is a B pixel, thereby realizing full-color display of the first picture. Similarly, one of the second sub-pixel 1212a, the fourth sub-pixel 1212b and the sixth sub-pixel 1212c is an R pixel, one is a G pixel, and one is a B pixel, thereby realizing full-color display of the second picture.

[0048] In some embodiments, the first color film 131a, the second color film 131b and the third color film 131c are respectively red color films, green color films or blue color films, and the colors of the first color film 131a, the second color film 131b and the third color film 131c are different.

[0049] In the embodiments of the present application, the first picture display pixel 1211 and the second picture display pixel 1212 both emit light through the first color film 131a, the second color film 131b or the third color film 131c, and one of the first color film 131a, the second color film 131b and the third color film 131c is a red color film, one is a green color film, and one is a blue color film, thereby realizing full-color display of the first picture.

[0050] In some embodiments, the color of the first color film 131a is the same as the color of the second sub-pixel 1212a, the color of the second color film 131b is the same as the color of the fourth sub-pixel 1212b, and the color of the third color film 131c is the same as the color of the sixth sub-pixel 1212c. In this way, the viewing angle range of the second picture display pixel 1212 can include the side and the middle position, so that the user can see the second picture when standing at the middle position or the side. For example, as shown in FIG. 6, the included angle θ in the figure is the viewing angle range of the second picture display pixel 1212, and at this time, the viewing angle range of the second picture display pixel 1212 is the right side and the middle position. Figure 2

[0051] In some embodiments, the color of the first color film 131a is different from the pixel color of the first sub-pixel 1211a, the color of the second color film 131b is different from the pixel color of the third sub-pixel 1211b, and the color of the third color film 131c is different from the pixel color of the fifth sub-pixel 1211c.​

[0052] In the embodiments of the present application, when the color of the first color film 131a is different from the pixel color of the first sub-pixel 1211a, the first sub-pixel 1211a will not emit light from the first color film 131a, and similarly, the third sub-pixel 1211b will not emit light from the second color film 131b, and the fifth sub-pixel 1211c will not emit light from the third color film 131c. In this way, the visual angle range of the first picture display pixel 1211 can be prevented from overlapping with the visual angle range of the second picture display pixel 1212, so as to avoid seeing the superimposed display picture of the first picture and the second picture at the same angle, and to avoid affecting the viewing experience.

[0053] In some embodiments, the color of the first color film 131a is the same as the pixel color of the third sub-pixel 1211b, the color of the second color film 131b is the same as the pixel color of the fifth sub-pixel 1211c, and the color of the third color film 131c is the same as the pixel color of the first sub-pixel 1211a.

[0054] In some embodiments, the color of the first color film 131a is the same as the color of the third sub-pixel 1211b, the color of the second color film 131b is the same as the color of the fifth sub-pixel 1211c, and the color of the third color film 131c is the same as the color of the first sub-pixel 1211a. In this way, the visual angle range of the first picture display pixel 1211 can include the other side edge, so that the user standing on the other side edge can see the first picture. For example, as shown in Figure 3 The included angle γ in the figure is the visual angle range of the first picture display pixel 1211, at this time, the visual angle range of the first picture display pixel 1211 is the left side.

[0055] In some embodiments, the pixel color of the first sub-pixel 1211a and the second sub-pixel 1212a is different, the pixel color of the third sub-pixel 1211b and the fourth sub-pixel 1212b is different, and the pixel color of the fifth sub-pixel 1211c and the sixth sub-pixel 1212c is different.

[0056] In some embodiments, the pixel color of the second sub-pixel 1212a is the same as the pixel color of the third sub-pixel 1211b, the pixel color of the fourth sub-pixel 1212b is the same as the pixel color of the fifth sub-pixel 1211c, and the pixel color of the sixth sub-pixel 1212c is the same as the pixel color of the first sub-pixel 1211a.

[0057] In some embodiments, as shown in Figure 4 The black matrix 132 is covered on the pixel layer 12 to form a whole layer structure, the area of the black matrix 132 arranged opposite to the second picture display pixel 1212 along the x direction is removed by patterning treatment, and the color film 131 is arranged opposite to the second picture display pixel 1212 in the area.

[0058] It should be noted that in the embodiments of the present application, "patterning" refers to a step of forming a structure with a specific pattern, which can be a photolithography process including one or more of the steps of forming a material layer, coating photoresist, exposure, development, etching, photoresist stripping, etc. Of course, "patterning" can also be an imprinting process, an inkjet printing process, or other processes.

[0059] In some embodiments, a pixel circuit layer is further provided between the substrate 11 and the pixel layer 12, which can include a thin film transistor and a capacitor. The thin film transistor includes an active layer, a gate electrode, a source electrode and a drain electrode. The capacitor includes a first plate and a second plate.
