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

The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen

How to do regular maintenance of large-screen optical equipment, DLP seamless splicing screen wall maintenance guide, as long as you remember and follow it, DLP seamless splicing screen wall will be no problem for 50 years. 1. Put the large-screen optical equipment in an environment that is easy to ventilate to increase the service life of the bulb of the large-screen optical equipment. 2. Regular cleaning of large-screen optical equipment can improve the brightness and contrast of the large-screen display system (increased by 10% to 30%). 3. When the temperature is very low, it will affect the normal use of the outdoor large screen. Generally, it is recommended to temporarily stop using it when it is below minus 30 degrees Celsius. Of course, taking other measures, such as installing an air conditioner in the box, can also ensure normal use. 4. Pay attention to the maintenance of daily optical components (color wheel, LCD panel, polarizer, lens, etc.) to prevent premature aging. 5. If the DLP seamless splicing wall fails, please contact the manufacturer in time. The above five points are the maintenance guide for DLP seamless splicing screen wall for everyone. I hope you will pay more attention to it during use.
