Abstract

The present invention relates to an artwork display screen and a manufacturing method thereof, the method comprising: depositing a buffer layer, a semiconductor active layer, a gate insulating layer, a gate layer and an interlayer dielectric layer on the base substrate, and then depositing The interlayer dielectric layer in the edge area of ​​the display panel is etched to form a first groove surrounding the pixel area of ​​the display panel, and then a second groove is formed on the bottom surface of the first groove, Next, metal material is deposited in the first groove and the second groove to form a metal bump, and then a third groove is formed on the upper surface of the metal bump; then, in the interlayer dielectric layer A planarization layer is formed on the planarization layer, and then an anode layer, a light emitting layer and a cathode layer are formed on the planarization layer.

Description

technical field [0001] The invention relates to the technical field of semiconductor packaging, in particular to an artwork display screen and a manufacturing method thereof. Background technique [0002] Existing art display screens usually use organic light emitting diode display panels as their main parts, and the organic light emitting diode display panels have the advantages of self-illumination, fast response, wide viewing angle, and simple manufacture. In the preparation process of the existing OLED display panel, a buffer layer, a semiconductor active layer, a gate insulating layer, a gate, an interlayer dielectric layer, a source drain, a planarization layer, and an organic LED unit. The existing art display screen is prone to cracking and damage during use. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide an art display screen and a manufacturing method thereof....
