Abstract

The invention provides a display panel and a spliced ​​display screen. The display panel includes a display structure, a flexible circuit board and a supporting substrate; the supporting substrate is fixed on the lower surface of the substrate through a first adhesive layer, and the supporting substrate includes an opposite second One side and the second side, wherein the first side is flush with the first boundary of the substrate, and the second side is embedded inward from the second boundary of the substrate to form an embedded recess; the flexible circuit board includes a U-shaped The first horizontal portion, the curved portion and the second horizontal portion, wherein the curved portion protrudes outward from the first boundary of the substrate, wherein the protruding distance of the curved portion is equal to the embedding distance of the embedded concave portion. The display screen spliced ​​by the display panels can make the sides of the display structure seamlessly spliced.

Description

technical field [0001] The invention relates to the field of light-emitting diode displays, in particular to a display panel and a spliced ​​display screen. Background technique [0002] With the increasing diversification of display requirements, displays made of inorganic material micro-LED display panels have the characteristics of low energy consumption, long life and strong stability. In the prior art, due to the limitation of mass transfer, multiple display panels are often required to be spliced ​​to form a large-area display. However, in the existing spliced ​​display screens, there are often gaps between multiple display panels, which will cause shadows, and the test pads are not easy to arrange, and the arrangement on the upper surface of the display panels is not conducive to testing. Contents of the invention [0003] Based on solving the above problems, the present invention provides a display panel, which includes a display structure, a flexible circuit boar...
