1, What is a touch LCD screen?
Touch LCD screen is an intelligent human-computer interaction device that adds touch function on the basis of ordinary LCD display screen (LCD). Users do not need to use a mouse or keyboard, they can simply click, slide, zoom, etc. on the screen with their fingers or stylus to achieve operations.
It is like the screen of a smartphone, but can be made larger and more robust, widely used in self-service terminals, industrial equipment, education and teaching, conference systems, medical instruments, smart homes and other fields.
2, Composition of Touch LCD Screen
A complete touch LCD screen generally includes the following parts:
Liquid Crystal Display (LCD): responsible for displaying images, text, videos, and other content.
Touch sensitive layer (touch screen): installed on the surface of the LCD screen, used to sense the touch action of fingers or stylus.
Control board (touch controller): responsible for converting touch signals into instructions that can be recognized by the computer.
Machine shell (customizable): Provides protection and structural support, and can be customized in size, color, and interface according to the project.
