綜上所述，提供一種液晶顯示模組100。透過將感光器150設置於用以固定蓋板190及框架131的雙面膠帶170處，而不用設計額外空間放置感光器150，如此便能在考量縮小螢幕裝置時，邊框不須再保留感光器150的設置空間，增加了外觀設計上的空間。再者，雙面膠帶170所形成的擋牆亦能阻擋來自其他方向的光線，避免干涉感光器150。To sum up, a liquid crystal display module 100 is provided. By disposing the photoreceptor 150 on the double-sided adhesive tape 170 used to fix the cover 190 and the frame 131, there is no need to design additional space for placing the photoreceptor 150, so that when considering the reduction of the screen device, the frame does not need to retain the photoreceptor The setting space of 150 increases the space in appearance design. Furthermore, the blocking wall formed by the double-sided adhesive tape 170 can also block light from other directions to avoid interference with the photoreceptor 150 .
