The working principle of LED touch screen

The working principle of LED touch screen:

1. LED Screen: An LED screen is composed of multiple LED lights, capable of displaying images and text with high brightness, high definition, and high contrast.

2. Touchpad: The touchpad is a transparent film installed in front of the LED screen, which can recognize the position and action of finger touches.

3. Controller: The controller acts as an intermediary between the LED screen and the touchpad, converting signals detected by the touchpad into electronic signals that can be transmitted to a computer or other device.

4. Software: Software is the program used to control and manage LED touch screens, enabling different functions and applications. When a user touches an LED touch screen, the touch panel detects the position and action of the finger and transmits this information to the controller. The controller converts this information into electronic signals and sends them to computers or other devices. The software on these computers or devices executes corresponding operations based on the received signals, such as moving, clicking, zooming, etc. The emergence of 1.5-inch touch screens in Guangdong has made the operation of electronic devices more intuitive and natural.
