How to make the LED display screen more high-definition

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 principle and characteristics of DLP seamless splicing screen

Almost all current smart projections use DLP seamless splicing screen projection technology, so how much do you know about this technology? Today I will briefly analyze the working principle and characteristics of this technology. The light source hits the light on the lens to obtain usable parallel light. The parallel light passes through the color wheel to obtain a uniform rectangular spot, which is then processed by DMD, the core component of DLP seamless splicing screen projection technology. Finally, the light is hit on the projection lens and passed The lens gets the projection we need, which is the working principle of DLP seamless splicing screen projection technology. DLP seamless splicing screen display board has extremely fast response time, you can switch independent pixels many times when displaying a frame of image. In addition, the strong reflective surface of the DMD chip can eliminate the obstacles in the light path and allow more light to be projected on the screen, and maximize the use of the projector’s light source to obtain a higher contrast picture. These are DLP seamless splicing screen projections. Advantages of technology. In addition, in terms of size, the DLP seamless splicing screen chip is lighter and smaller, which is one of the reasons why DLP seamless splicing screen projection technology is widely selected for small-size products such as smart projection. In addition, at the end of last year, Texas Instruments also launched a smaller size 1080P chip for smart projection. The compression of the chip size

Digital signage enhances customer experience
