What's the difference between a touch display module and a touch screen?

Touch screen display modules and touch screens have certain differences in function and structure.

A touchscreen, also known as a "touch-controlled screen" or "touch panel," primarily functions to receive input signals from objects such as fingers. When users touch graphical buttons on the screen, the tactile feedback system on the screen drives various connected devices according to preprogrammed routines, thus enabling operation of the device. Due to its simple, convenient, and natural human-machine interaction method, touchscreens are widely used in mobile phones, tablets, cash registers, industrial fields, and more.

While touch display modules are more complex, integrating both touch sensors and display screens. Touch display modules not only have the touch sensing function of a touch screen but also have the ability to display images and video information. This means that touch display modules can not only detect users' touch operations but also intuitively present information to users in the form of images or videos. Therefore, touch display modules play a crucial role in smart devices such as smartphones and tablets.

Overall, touchscreens primarily focus on touch sensing functions, while touch display modules further integrate display capabilities, achieving a perfect combination of touch operation and visual display. Both play important roles in electronic devices and jointly enhance the interaction experience between users and devices.
