In the display panel, the light emitting areas of the light emitting unit rows 122 of the same sub-pixel island 121 are continuous but not overlapped with each other in the first direction, so that the 3D display effect of the display panel in the viewing area range can be ensured to be continuous, and the use experience of a user can be ensured.

In the embodiment of the present application, as shown in fig. 1, the display substrate 10 includes a substrate 11, a pixel unit layer 12, and a first black matrix layer 13, where the pixel unit layer 12 is located on one side of the substrate 11, and the first black matrix layer 13 is located on one side of the pixel unit layer 12 away from the substrate 11.

As shown in fig. 2 and 3, the pixel unit layer 12 includes a plurality of pixel islands 120, and optionally, a plurality of pixel islands 120 are arrayed on one side of the substrate 11. The pixel island 120 includes a plurality of sub-pixel islands 121, and in the present embodiment, the pixel island 120 includes three sub-pixel islands 121, and each sub-pixel island 121 emits light of a different color, and optionally, the three sub-pixel islands 121 include a sub-pixel island 121 emitting red light, a sub-pixel island 121 emitting blue light, and a sub-pixel island 121 emitting green light, so that the pixel island 120 can emit white light.

As shown in fig. 3, the subpixel island 121 includes at least two light emitting cell rows 122, and light emitting regions of the light emitting cells 123 of the light emitting cell rows 122 correspond to an opening region of the first black matrix layer 13; in a first direction perpendicular to the light-emitting unit rows 122, a projection of the second side 1232 of the light-emitting area of one light-emitting unit 123 in one light-emitting unit row 122 on the boundary of the display substrate 10 overlaps with a projection of the first side 1231 of the light-emitting area of an adjacent light-emitting unit 123 in an adjacent light-emitting unit row 122 on the boundary of the display substrate 10.

The display substrate 10 of the present application adopts a design scheme of pixel island 120 division, that is, a large RGB LED sub-pixel is divided into smaller sub-pixels (i.e., in the embodiment of the present application, the sub-pixel island 121 includes a plurality of light emitting units 123), and each sub-pixel can individually control a display gray scale.

Therefore, in the visual area range corresponding to the display panel, a user can watch continuous 3D display effect pictures, and due to the fact that the light emitting areas are not overlapped, the use experience of the user can be guaranteed.

Meanwhile, along the first direction perpendicular to the light emitting unit rows 122, the light emitting area of one light emitting unit 123 in one light emitting unit row 122 is not overlapped with the light emitting area of an adjacent light emitting unit 123 in an adjacent light emitting unit row 122, so that crosstalk between adjacent views can be reduced, and the use experience of a user can be further guaranteed.

It should be noted that, in fig. 2, for convenience of visual illustration, the pixel islands 120 and the sub-pixel islands 121 are arranged, and therefore, the pixel islands 120 and the sub-pixel islands 121 are marked by dashed-line frames.

In the embodiment of the present application, as shown in fig. 3, by ensuring that the first side 1231 of the light emitting region of the second light emitting unit 123 of the light emitting unit row 122 located at the first end is collinear with the second side 1232 of the light emitting region of the first light emitting unit 123 of the light emitting unit row 1211 located at the second end in the same sub-pixel island 121, it is ensured that the light emitting regions of the light emitting unit rows 122 are arranged as densely as possible in the second direction parallel to the display substrate 10, and the resolution of the display panel can be further improved.

As shown in fig. 5, in the same sub-pixel island 121, the light emitting units 123 in any two adjacent light emitting unit rows 122 are arranged in a staggered manner, so that the first black matrix layer 13 is subsequently prepared on one side of the pixel unit layer 12, and the opening area of the first black matrix layer 13 is conveniently corresponding to the light emitting area of the light emitting unit 123, thereby facilitating the preparation of the structure shown in fig. 3.

In the embodiment of the present application, in fig. 4, a portion of the first black matrix layer 13 between two adjacent light emitting unit rows 122 is removed, so that the corresponding relationship between the opening region of the first black matrix layer 13 and the light emitting region of the light emitting unit 123 can be easily and intuitively understood.

In the embodiment of the present invention, in the same sub-pixel island 121, the light emitting units 123 in any two adjacent light emitting unit rows 122 are arranged in a staggered manner, and after the first black matrix layer 13 is prepared, the first black matrix layer 13 can shield a part of the light emitting units 123, so that in the same sub-pixel island 121, the projections of the light emitting areas of the light emitting units 123 in the first direction perpendicular to the light emitting unit rows 122 are not overlapped and are arranged closely. In the visual area range corresponding to the display panel, a user can view continuous 3D display effect pictures, and due to the fact that the light emitting areas are not overlapped, crosstalk between adjacent views can be reduced, and use experience of the user can be guaranteed.

Alternatively, the subpixel island 121 includes at least seven light emitting cell rows 122, and the light emitting cell rows include at least five light emitting cells 123. Thereby enabling each sub-pixel island 121 to provide at least 35 viewing zones, thereby effectively increasing the number of viewing zones of the display panel.

That is, the pixel island unit 124 includes two rows of the pixel islands 120 arranged in the first direction, each row having three pixel islands 120; including three columns of pixel islands 120 arranged in a first direction, and two pixel islands 120 per row. Since the ratio of the size of the pixel island 120 in the first direction to the size of the pixel island 120 in the second direction is 3/2, the size of the pixel island unit 124 in the first direction is equal to the size of the pixel island unit 124 in the second direction.

It should be noted that the structure of the pixel island unit 124 is shown in fig. 6 for convenience of visual illustration, and therefore, the pixel island unit 124 is marked by a dotted-line frame.

In the embodiment of the present application, the display panel provided in the embodiment of the present application is described with reference to a specific LED display product. Taking the viewing distance of 3m (meters) as an example, in order for an LED display product to make the visible space reach 6m, the visible angle needs to reach ± 45 °, and the average value of the interpupillary distance of the human eyes is 65mm (millimeters), so that the width of each view is required to be less than 65mm in order to make the two eyes of the user fall under different views, and the number of views is 6000/65 ═ 93.
