Difference and relationship between LCD and touch screen

With the continuous development of display technology, people are increasingly inseparable from display screens, which are electronic components. It is not so easy for people to understand the mysteries behind them. Recently, someone has been asking if LCD and touch screen are not the same product? What is the relationship and difference between them? Next, let's give you a science popularization about the differences and relationships between LCD and touch screen.
1. The Difference between LCD and Touch Screen
Simply put, LCD and touch screen are two different components. LCD is mainly responsible for display, while touch screen is mainly responsible for touch and control. Firstly, their two main bodies are different. An LCD display screen is a display device composed of light emitting diodes arranged in a row, which mainly refracts light to produce a picture; The touch screen is an inductive control display device that receives input signals such as contacts. The essence of the touch screen is a sensor, and the two cannot be compared.
2. The Relationship between LCD and Touch Screen
The relationship between LCD and touch screen can be said to be complementary and indispensable. Everyone has seen the display screen on the mobile phone we use, which is formed by the combination of LCD and touch screen to form an LCD display assembly, achieving both display and touch effects. There are also many ways to fit LCD and touch screen, with two common ones being full fit and frame fit. Full fit is generally required for consumer products to be light and thin. The advantage of this fit method is that it is thin, and the display effect is good, which is not easy to get into dust; The process of frame pasting is generally used in industrial scenarios, and it has high reliability because the reinforcement with iron frames is not easy to break the screen.
