Abstract

An embodiment of the present application discloses a display panel and a splicing display panel. The display panel includes a display panel main body and a light grating layer. The light grating layer is formed on the display panel main body. The light grating layer includes a plurality of light gratings, and the light gratings are arranged at intervals along a first direction. The light gratings are arranged at intervals along a second direction, and the first direction intersects the second direction.

First claim

What is claimed is:

1. A splicing display panel, comprising:
at least two first display panels spliced, wherein a gap is defined between adjacent two of the first display panels; and
at least one second display panel disposed on light exiting surfaces or light incident surfaces of adjacent two of the first display panels and shielding the gap, wherein the second display panel comprises a display panel main body and a light grating layer, and the light grating layer is formed on the display panel main body;
wherein side view brightness of the display panel main body is greater than side view brightness of the first display panel;
wherein the light grating layer comprises a plurality of light gratings, the light gratings are arranged at intervals along a first direction, the light gratings are arranged at intervals along a second direction, and the first direction intersects the second direction.

2. The splicing display panel according to claim 1 , wherein the first display panel is a liquid crystal display panel, and the display panel main body comprises:
a driver substrate;
a light emitting device disposed on the driver substrate;
an encapsulation layer covering the light emitting device;
a color filter layer formed on the encapsulation layer, and
a planarization layer formed on the color filter layer;
wherein the light grating layer is formed on the planarization layer.

3. The splicing display panel according to claim 1 , wherein the light gratings extend along a first direction.

4. The splicing display panel according to claim 3 , wherein the light grating layer further comprises a connection body; along the first direction, the connection body is connected between adjacent two of the light gratings; and a thickness of the connection body is less than a thickness of the light grating.

5. The splicing display panel according to claim 1 , wherein the light gratings comprise a plurality of first light gratings and a plurality of second light gratings, and the first light gratings extend along the first direction, the first light gratings are arranged at intervals along the first direction to form first lines; and
the second light gratings extend along the second direction, and the second light gratings are arranged along at intervals the second direction to form second lines.

6. The splicing display panel according to claim 5 , wherein at least one of the second light gratings is located between adjacent two of the first lines; and at least one of the first light gratings is located between adjacent two of the second lines.

7. The splicing display panel according to claim 6 , wherein along the first direction, a first aperture is located between adjacent two of the first light gratings; and along the second direction, the second light gratings are disposed to correspond to the first apertures;
along the second direction, a second aperture is located between adjacent two of the second light gratings; and along the first direction, the first light gratings are disposed to correspond to the second apertures; and
along the second direction, at least some of the first apertures correspondingly form at least one first light channel; along the first direction, at least some of the second apertures correspondingly form at least one second light channel.

8. The splicing display panel according to claim 7 , wherein at intersecting positions between the first lines and the second lines, the first light gratings and the second light gratings are connected or disposed at an interval.

9. The splicing display panel according to claim 1 , wherein the light grating layer comprises a first region located in a middle region and a second region disposed on two sides of the first region, and an arrangement density of the light gratings in the first region is less than an arrangement density of the light gratings in the second region.
