Problems solved by technology

Due to the inconsistent coefficients of thermal expansion and shrinkage of the frame glue 101, the dispensing part 120, the detection sensor 110, and the display panel 200, after the display device is put into the environmental reliability test, the display panel is deformed, and the display panel can be clearly seen from the light-emitting side. It is obvious that there is an indentation on the fingerprint detection module, which affects the appearance of the display device
