What are the uses of the LCD display module?

The LCD display module is a component that assembles liquid crystal display devices, connectors, integrated circuits, PCB circuit boards, backlight sources, and structural parts together. To put it simply, the LCD module is LCD screen + LED backlight board + PCB board + iron frame.

The display components of power terminals, instrumentation, etc. are liquid crystal modules, which are equivalent to the picture tube in the CRT.

Other parts include power supply circuits, signal processing circuits, etc., and of course the housing.

The module is mainly divided into screen and backlight components. The two parts are assembled together, but are independent of each other when working (that is, the circuits are not related).

The principle of liquid crystal display is that the backlight assembly emits uniform surface light, and the light is transmitted to our eyes through the LCD screen. The function of the screen is to process these lights in pixels to display images. Both parts contain a large number of components.

The liquid crystal display module (LCD) is a type of display used in digital clocks and many portable computers. LCD display uses two pieces of polarization data, between them is a liquid crystal solution. When the current passes through the liquid, the crystals are repositioned so that light cannot pass through them. Therefore, each crystal is like a blind, both allowing light to pass through and blocking it. Liquid crystal display (LCD) technology and information products are now being developed towards light, thin, short, and small. Display products with a long history in computer peripherals are of course no exception. With ease of carrying and transportation as the prerequisite, traditional display methods such as CRT video tube display and LED display board, etc., are subject to factors such as excessive volume or huge power consumption, and cannot achieve the user's reality. demand. The development of liquid crystal display technology is in line with the current trend of information products, with right-angle display, low power consumption, small size, and zero radiation.
