Problems solved by technology

However, LED display screens have high requirements on the accuracy of the mask due to the relatively dense lamp beads, which leads to difficult production of the mask, low yield, and high cost. Problems such as the screen rendering modular effect
Therefore, the market tries to use inkjet technology to replace the mask. However, the current inkjet technology is to spray ink on the lamp beads of the LED display, and the ink needs to be sprayed in the gap between the lamp beads. High precision requirements, resulting in low inkjet efficiency

Abstract

The invention relates to a display screen, comprising a substrate and a plurality of light-emitting units, wherein each of the light-emitting units is arranged on the substrate, a thermochromic ink layer is arranged on the light-emitting unit, and the thermochromic ink layer is used for changing from a colored state to a transparent state when the temperature of the thermochromic ink layer reachesa color-changing temperature. The invention ensures that the display screen keeps the color consistency of the rest screen state, avoids affecting the brightness of the display screen when the display screen is bright, and can effectively improve the ink jet efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen. Background technique [0002] LED display (LED, Light Emitting Diode, light emitting diode) is used more and more widely. In order to improve the contrast of LED display and solve the problem of display color difference, the current technical solution is to add a plastic mask on the LED display. However, LED display screens have high requirements on the accuracy of the mask due to the relatively dense lamp beads, which leads to difficult production of the mask, low yield rate, and high cost. The screen presents problems such as the modular effect. Therefore, the market tries to use the inkjet process to replace the mask. However, the current inkjet process is to spray ink on the lamp beads of the LED display, and the ink needs to be sprayed in the gap between the lamp beads. The precision requirements of the inkjet are high, resulting in low inkjet efficiency...
