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

The LCD screen is the most intimate part of the touch all-in-one machine and the audience, and it is also the most critical part to improve the user experience. Therefore, the quality of the LCD screen directly determines the quality and application efficacy of the touch all-in-one machine. At present, in the touch all-in-one market, the most used LCD screens are plasma, LCD, and LED. The use period is usually between 6 and 10 years. Although we can extend the use period by replacing the lamp tube, but With the lamp tube replaced, a new problem has arisen because the liquid crystal in the screen will also age. In this case, the screen display of the touch all-in-one will inevitably affect the picture quality displayed by the touch all-in-one. The touch screen is a very important part of the touch all-in-one machine. It is an inductive liquid crystal display device that can receive input signals such as contacts. The current touch screens on the market mainly include resistive touch screens, capacitive touch screens, surface acoustic wave touch screens, and infrared touch screens. Each touch screen has its own advantages and disadvantages. You must combine your own use environment and the advantages and disadvantages of the touch screen to choose a touch screen suitable for your product. As the pillar supporting the normal operation of the control integrated machine, the quality of the power supply needs to be seen in the long-term use process. You can consult the supplier about the
