What are the characteristics of LCD?   Thin fuselage, space saving: Compared with the bulky CRT display, the LCD display only has one third of its space. Power saving, no high temperature: It belongs to low power consumption products, cannot burn completely, relative to CRT display, because imaging technology inevitably produce high temperature. No radiation, good for health: LCD is completely radiation-free, which is a good news for people who work in front of the computer all day. Soft screen does not hurt the eyes: Different from CRT technology, LCD screen will not flash, it can reduce the screen damage to the eyes, and the eyes are not easy to fatigue.

The small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. It is not reflective for indoor applications, and the display contrast is as high as 5000:1; it is lightweight and ultra-thin, High precision, small space for transportation and use, quiet and efficient heat dissipation. Small-pitch LED display products have a wider color gamut space and faster response speed than ordinary large LED screens, and can realize seamless splicing and modular maintenance of any size. The whole picture played is uniform in color, high-definition lifelike, no abnormal display such as sweat spots and bright lines that are common on ordinary screens, and the picture switching is soft and does not flicker, and the picture quality is very delicate, which is close to the playback effect of a TV. The contrast ratio of 5000:1 can show excellent blackness when the screen is black, and it is the best among similar products. The biggest competitiveness of indoor high-density and small-pitch LED displays lies in the complete seamlessness of the large screen and the natural and true display colors. At the same time, in terms of post-maintenance, the LED large screen already has a mature point-by-point calibration technology. The large screen used for more than one or two years can be used to perform a one-time calibration of the entire screen. The operation process is simple and the effect is very good. When using a small-pitch LED display, pay attention

Polarizer is an important part of LCD screen. With the emergence of special full matching technology, polarizers are more and more widely used in LCD. What role does polarizer play in LCD?   Polarizer is widely used in LCD industry, and LCD needs to use polarizer. Polarizer and liquid crystal play an important role in development. In the production process, two pieces of ordinary tempered glass are printed on the circuit, and then glued together and folded. Then the liquid crystal is injected into the middle of the two sides of the glass, and the polarizer is pasted on the top and bottom of the glass.   The upper and lower glass should be pasted with polarizer, but pay attention to the direction. If the lower polarizer filters the x-direction light, the upper polarizer can only filter the y-direction light. If the upper polarizer filters out the light in the Y direction and the lower polarizer filters out the light in the X direction, the user can see nothing. Although the LCD works normally, the polarizer is not visible to the naked eye. Now the LCD color screen is generally only on the film, not on the film, the product technology innovation.   People who have studied physics should know what polarized light is. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizers close to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1 mm. Without
