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

At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which
