Detailed explanation of the composition of the LCD screen

Author : Senior LCD screen seller Date : 2021/4/21 21:15:10
With the increasing innovation of display technology, the display has gradually become a subdivision field. Different types of display screens have different functions, application scenarios, and different names. Today, the editor will take you to get to know the LCD module. What are the important components of the LCD module?

When it comes to LCD liquid crystal display module, everyone will think that it is a combination, and the LCD liquid crystal display module is mainly composed of LCD panel, backlight, FPC and IC, so it is called LCD liquid crystal display module. group.

1. The LCD panel of the liquid crystal display module

The LCD panel is commonly known as glass. It is the most important core component of the LCD liquid crystal display module. The quality of a display mainly depends on the quality of the LCD panel, which will directly affect the sensory experience of the screen. The LCD panel is generally produced as a large board, which is cut into small boards according to different sizes and becomes a core component.

2. Backlight of lcd liquid crystal display module

The backlight refers to the light source behind the LCD liquid crystal display module. Without the light source, the display screen will not have any display. The components of the backlight are composed of the light source, the light guide plate, the optical film, and other structural parts. The backlight can control the brightness according to the lamp beads and power consumption. If you need high brightness, you can change it according to the structure of the backlight. Of course, it cannot be adjusted infinitely. Its brightness should be integrated according to the internal structure and power consumption of the whole machine. Designed.

3. FPC of LCD module

FPC flexible circuit board, which is a flexible circuit board with high wiring density, light weight, thin thickness, and good bendability. The LCD liquid crystal display module conducts electricity through the FPC to realize the display function. It is also an indispensable important component. Of course, the FPC is not the only conductive component. There are also some large screens that are energized through USB and other interfaces. The FPC is a common conductive component for small and medium-sized LCD liquid crystal display modules.

Fourth, the IC of the LCD module

IC is what everyone often says. A chip is a kind of miniature electronic device or component. It uses a certain process to interconnect the transistors, diodes, resistors, capacitors, and inductors and other components and wiring required in a circuit to make a small piece. Or a few small pieces of semiconductor wafers or dielectric substrates, and then packaged in a package to become a miniature structure with the required circuit functions. With it, any function can be realized.

I believe everyone has a certain understanding of the important components of LCD liquid crystal display modules. LCD liquid crystal display modules have the characteristics of high definition, high reliability, and low cost. You can focus on them when selecting models. Consider the lcd liquid crystal display module.
