The main difference between touch panels and regular screens is reflected in their interactivity and application scenarios.

1. Interactivity: Touch screen display is an interactive display that can be operated based on the user's finger position and movements, achieving more intelligent and convenient input and control. However, ordinary display screens can only be used to display images and text, cannot perceive touch, and lack interactivity.

2. Application scenarios: Touch screen displays have a wide range of application scenarios, such as mobile phones, tablets, self-service terminals, smart TVs, game consoles, etc., especially suitable for situations where users need to directly perform touch operations. Ordinary display screens are mainly used in computer displays, mobile electronic devices, televisions, and other fields, mainly responsible for displaying images and text functions.

In addition, there are differences in functionality and display technology between touch screens and regular displays. Touch screen displays not only have display functions, but also have the ability to perceive touch and interact, while regular displays only have display functions. In terms of display technology, ordinary displays can use various technologies such as CRT, LCD, LED, and OLED, while touch displays mainly use touch technologies such as resistive and capacitive.

Overall, there are significant differences between touch screens and regular displays in terms of interactivity, application scenarios, functionality, and display technology. Touch screen displays have higher interactivity and a wider range of application scenarios, while ordinary displays mainly serve the functions of displaying images and text.
