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

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.

Compared with traditional advertising machines, what are the advantages of LCD advertising machines? The following editor will leave a brief introduction: The LCD advertising machine is very convenient to maintain the advertising content. The traditional advertising machine needs to copy the content with a computer first, and then a dedicated person will go to the advertising machine outlet to replace the CF card, which causes a waste of human resources and is very inefficient; the electronic online advertising machine is accessed through the Internet IP and passed in the office. Control the host, directly download the content to be updated to the advertising machine, and can delete, sort, set playback rules, interstitial control, aerial control, etc., all can be completed in a few minutes, and save a lot of labor costs. The advertising playback management of the LCD advertising machine has become more flexible and faster. Traditional LCD advertising players need to pre-arrange the program playlists. How to broadcast at the outlets usually takes a long time to implement after the arrangement is completed, and it is very inconvenient to replace one round and requires a lot of manpower; electronic online advertising players This problem can be solved easily. All outlets arrange programs, change, insert broadcast, and broadcast arrangements only need to be controlled by software on the server management side, and the order can be issued. It can be said that an advertisement can be placed overnight. To broadcast on designated outlets in various cities, the speed is very
