The LCD display module is a type of display used in digital clocks and many portable computers. It uses two pieces of polarized material with a liquid crystal solution between them. The LCD display module is a very delicate thing, which has many advantages such as low power consumption, no radiation, no dizziness, and so on. And it protects the eyesight of the user to a great extent. With the development of liquid crystal display technology and the continuous decline of liquid crystal prices, today's liquid crystal display has become a must-have electronic product for many people. So what are the components of the LCD screen?
The LCD panel is commonly known as glass. It is the most important core component of the LCD display module. The quality of a display mainly depends on the quality of the LCD panel, which directly affects 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.
The backlight refers to the light source behind the LCD 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, you cannot turn up the screen without a limit. The degree of its brightness is designed based on the internal structure and power consumption of the whole machine.
FPC flexible circuit board, which is a flexible circuit board with high wiring density, lightweight, thin thickness, and good bendability. The LCD display module conducts electricity through the FPC to realize the display function. It is also an important component that is indispensable. Of course, FPC is not the only conductive component. Some large screens are energized through USB and other interfaces. FPC is a common conductive component for small and medium-sized LCD display modules.
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.
The LCD display module has strict requirements on air humidity, so it must be able to work in a relatively dry environment. In particular, moisture cannot be brought into the interior of the display screen, so this is particularly critical for some users whose working environment is relatively humid. If there is water in the LCD screen, what you need to do is place it in a dry place to allow the water to evaporate. Do not turn on the power rashly at this time. Otherwise, the LCD electrodes of the screen will be corroded, causing liquid crystal damage to the display.
