What are the components of an LCD screen? (2)

With the increasing innovation of display technology, LCD has gradually become a subdivision. Different types of LCD screens have different functions, application scenarios, and names. Today, Xiaobian will take you to know the LCD liquid crystal display module, and talk about what important components are the LCD liquid crystal display module composed of? LCD liquid crystal display module, it is mainly composed of LCD panel, backlight, FPC and IC, so it is called LCD liquid crystal display module.

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

2. The backlight backlight of the LCD liquid crystal display module refers to the light source behind the LCD liquid crystal display module, and the display screen will not have any display without a light source, and the components of the backlight are composed of a light source, a light guide plate, an optical diaphragm, and other structural parts. The backlight can control the brightness according to the lamp beads and power consumption, if the brightness is high, it can be changed according to the structure of the backlight, of course, it is not infinitely bright, its brightness is designed according to the internal structure and the power consumption of the whole machine.

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

4, the ICIC of LCD liquid crystal display module is often said to be a chip is a kind of miniature electronic devices or components, using a certain process, the transistors, diodes, resistors, capacitors and inductors and other components and wiring required in a circuit are interconnected together, made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then encapsulated in a tube shell to become a miniature structure with the required circuit function. With it, any function can be achieved.
