Referring toFIG.1, the present embodiment provides a display panel100including: at least two display screens110, LED substrates120, and a cover plate130. Referring toFIG.2, at least two display screens110are spliced together, and the display screen110includes a display area AA and a non-display area NA located on at least one side of the display area AA. The LED substrate120is disposed on the non-display area NA. The LED substrate120includes a substrate121and a light emitting device122disposed on the substrate121. A cover plate130is disposed on at least two display screens110. A groove131is provided on the side of the cover plate130close to the LED substrate120, and the LED substrate120is disposed in the groove131. The side surface of the substrate121is disposed opposite to the groove wall of the groove131, and a part of a groove wall surface131acorresponding to the side surface of the substrate121is a reflection interface132a.

Referring toFIG.2andFIG.3, it can be understood that the purpose of compensating light at seams can be achieved by arranging the LED substrate120in the non-display area NA, thereby eliminating the seams in front view. However, because the substrate121of the LED does not emit light, a black border may be seen on the edge of the substrate121when viewed from the side, which affects the display performance. By arranging the cover plate130, the groove131is provided on the side of the cover plate130close to the LED substrate120. The LED substrate120is disposed in the groove131, and the side surface of the substrate121is disposed opposite to the groove wall of the groove131. A part of the groove wall surface131acorresponding to the side surface of the substrate121forms a reflection interface132a. The reflective interface132amay reflect light emitted from the display screen110. It can visually eliminate the side-view black border to achieve the purpose of improving the display taste. In addition, the cover plate130covers the LED substrate120and the display screen110, so that a light emitting surface of the LED substrate120and a light emitting surface of the display screen110are consistent, to further enhance the display taste. The light emitting device122may be a sub-millimeter light emitting diode or a micrometer light emitting diode.

Referring toFIG.4andFIG.5, it should be noted that the display screen110includes a liquid crystal display screen or an LED direct-display display screen. Referring toFIG.4, the liquid crystal display screen includes an array substrate111, a liquid crystal layer112, and a color filter substrate113. The array substrate111and the color filter substrate113are disposed opposite to each other. The liquid crystal layer112is disposed between the array substrate111and the color filter substrate113.

It should be noted that the light emitting element114may be a sub-millimeter light emitting diode or a micron light emitting diode.

In this embodiment, the reflection interface132ais a smooth groove wall surface131a.

It can be understood that the smooth reflection interface132acan improve the reflection effect of the reflection interface132a. It can be understood that, after grinding or polishing, the groove wall surface131acan form a smooth reflective interface. It should be noted that, in some embodiments, the entire surface of the groove wall131acan be ground and polished to form the reflection interface132a, more light will be emitted from the reflection interface132a, and the cover plate130can be better lifted to eliminate the effect of black borders in the side view.

In this embodiment, there is a medium140between the groove wall131aand the LED substrate120, the refractive index of the cover plate130is greater than that of the medium140, and the groove wall131aand the medium140form a reflection interface132a.

Referring toFIG.3, it can be understood that when light passes through the media140with different refractive indices, refraction and reflection will occur at the interface between the two mediums140. The refractive index of the cover plate130is different from that of the medium140, and the groove wall surface131aof the cover plate130and the medium140form a reflection interface132a. The reflective interface132areflects the light from the display panel100to the outside, and visually eliminates the side-view black bars at the substrate121. It can be understood that, when the refractive index of the cover plate130is greater than that of the medium140, the refraction angle increases, and more light rays will be emitted to the outside, thereby improving the light output effect.

In this embodiment, the medium140includes air or a transparent solid material141.

It can be understood that when air is used as the medium140, the manufacturing process of the display panel100can be simplified, and the production cost of the display panel100can be reduced. Compared with other mediums140, air as the medium140can also reduce light loss. When the transparent solid material141is used as the medium140, a sealing property of the display panel100can be improved. The transparent solid material141includes silica gel, optical glue, or epoxy resin.

In this embodiment, in two adjacent display screens110, there is a gap150between the two display screens110. One LED substrate120is disposed on two adjacent display screens110and blocks the gap150.

It can be understood that the LED substrate120is disposed on two adjacent display screens110and cover the gap150. The gap150can be compensated by using the light emitted by the LED substrate120to eliminate the gap150visually. In addition, the LED substrate120can also be positioned at the center of the adjacent display panels100. As the compensation light source, the LED substrate120can evenly radiate the non-display area NA of the display panel100to improve the display performance of the display panel100.

In this embodiment, the grooves131and the gaps150are arranged to overlap.

It can be understood that the overlapping arrangement of the grooves131and the gaps150can enable the grooves131to better accommodate the LED substrate120and facilitate the formation of a reflective interface132abetween the LED substrate120and the groove wall surface131a.

In this embodiment, the transparent solid material141fills the gap150.

Referring toFIG.6, it can be understood that filling the gap150with the transparent solid material141can improve the sealing performance of the display panel100.

In this embodiment, the resolution of the LED substrate120is the same as the resolution of the display screen110.

It can be understood that, setting the resolution of the LED substrate120to be the same as the resolution of the display panel100can make the light captured by the human eye be the same as the light of the display panel100. After the light passes through the cover plate130, the LED substrate120and the light emitting surface of the display panel100are kept consistent, so as to improve the display performance of the display panel100.
