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.

Improve the contrast of the LED display: Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. Increase the gray level of the LED display: the gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest of the single primary color brightness. The higher the gray level of the LED display, the richer the color , The color is brighter; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. Nowadays, many LED display manufacturers can set the gray scale of the display to 14bit~16bit, so that the image level can distinguish the details and the display effect is more delicate, vivid, and colorful. Narrowing the dot pitch of the LED display: narrowing the dot pitch of the LED display can greatly improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of ​​the LED display, and the more details that can be displayed More, the screen display is more delicate and lifelike. The combination of LED display and video processor: The LED video processor can use

1. Keep the humidity in the environment where the digital signage is used, and don’t let anything with damp properties enter your digital signage. Powering on digital signage that contains moisture will cause corrosion of the digital signage components and cause permanent damage. 2. To avoid problems that may be encountered, we can choose passive protection and active protection, try to keep the items that may cause damage to the digital signage away from the screen, and when cleaning the screen, wipe it as gently as possible to reduce the possibility of injury Minimize. 3. The relationship between digital signage and our users is the closest, and it is very necessary to do a good job in cleaning and maintenance. After being exposed to wind, sun, dust, etc. in an outdoor environment for a long time, there will definitely be a piece of dust on the screen after a period of time. This needs to be cleaned in time to prevent dust from covering the surface for a long time to affect the viewing effect. 4. It is required that the power supply is stable and the grounding protection is good. Do not use it under severe natural conditions, especially strong thunder and lightning. 5. It is strictly forbidden to enter the screen body such as water, iron powder and other easily conductive metal objects. Digital signage should be placed in a low-dust environment as much as possible. A large amount of dust will affect the display effect, and too
