LED and LCD are two different technologies used in displays, and the touch functionality can be incorporated into either type of display.
In terms of touch functionality, both LED and LCD screens can incorporate touch technology using various methods, such as capacitive touch or infrared touch. The choice between LED and LCD primarily depends on factors like cost, power efficiency, picture quality, and specific application requirements.
LCD (Liquid Crystal Display) screens work by manipulating light through liquid crystals. They require a backlight to illuminate the display. LCD touchscreens typically have a layer of touch-sensitive material overlaid on top of the LCD panel. This touch layer can be resistive, capacitive, or infrared-based.
