The core technologies of touch display modules include touch sensing technology and display technology. Touch sensing technology is responsible for detecting user touch operations and converting them into electrical signals for processing. Common touch sensing technologies include resistive, capacitive, and infrared. Display technology is responsible for presenting text, images, and video information on the screen. Common display technologies include Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) displays.
Touch display modules usually consist of:
