Introduction to the composition of 7-inch LCD screen

1、 Control panel.

LCD control panel is often called glass. It is the main key component of LCD information touch group. The quality of the display mainly means to see the quality of the LCD control panel, which will directly affect the sensory experience of the picture. LCD control panel is generally a large board, which is cut into small boards according to different sizes and becomes a key component.

2、 LED backlight.

LED backlight refers to the light source behind the LCD information touch group. Without the light source display, there will be no display information. The components of LED backlight are composed of light source, light guide plate, optical film and other structural components. The brightness of LED backlight can be adjusted according to lamp beads and function loss. If the brightness must be high, it can be changed according to the structure of the backlight. Of course, it cannot adjust infinite brightness. Its brightness shall be designed according to the internal structure and the function loss of the whole machine.

3、 IC touch group

IC is usually called power chip. It is a kind of micro electronic equipment or components. Select the corresponding process. The components and wiring commonly used in the circuit, such as transistor, diode, resistance, capacitance and inductance, are connected on a small semiconductor chip or media substrate, and then encapsulated in the type to become a micro structure with the required circuit function. It can achieve any function.

The above is the composition of the 7-inch LCD screen introduced by Xiaobian. I hope you can help after reading it.
