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

LCD splicing screens are divided into optical seamless LCD splicing screens and electronic seamless LCD splicing screens. The realization principle of the optical seamless LCD splicing screen is to install a special optical glass panel body on an ordinary 3.5mm panel, and realize the principle of line-of-sight refraction through the glass, so that the originally split screen can be seen in an image through the optical glass , The seams with black edges are completely invisible, and the display effect of the picture is real. The realization principle of seamless LCD splicing screen electronics is that by installing a special electronic bar on each panel unit, the electronic bar emits light equivalent to LED, and the light is emitted by two electronic bars between the seams, which can be displayed on the display. Achieve seamless seams. The seamless LCD panel joining technology has reached an unprecedented level, realizing the arrival of the era of true seamless joining technology. The seamless LCD panel joining technology is used in the high-end display field. It can be said that the visual impact it brings is also unprecedented. The seam adopts full-screen active LED electronic pixel compensation display, and the optical lens and optical refraction principle are seamless. The pixel pitch of LED electronic pixel correction is 1.5mm or less. The electronic pixel compensation LED adopts SMD label technology and does not use large particle lamp-like display. After LED electronic pixel correction, the edge of the condenser lens with high transmittance is added to

In fact, until now, many people still confuse the touch all-in-one with an ordinary touchpad, and think that as long as the touchable screen is a touch all-in-one, this understanding is wrong. Bank ATM teller machines and traditional supermarket cash registers that we see every day belong to traditional touch panels instead of touch all-in-ones. Traditional touch panels are generally single-point or double-point touch, and touch all-in-ones are actually It can realize infrared or capacitive multi-touch. We will talk about the advantages and disadvantages of infrared touch and capacitive touch and their application fields next. What is the difference between a touch all-in-one machine and an ordinary touchpad, you must know Capacitive touch screens are currently mainly used for the display of high-end devices such as mobile phones, tablets, and computers. The touch function can be realized with the skin of a human finger, multi-point, handwriting, etc. can be realized without any problem. Capacitive touch screens cannot be touched with gloves, and there is no response to touch with gloves, and the larger the size of the product required, the more expensive it is. The capacitive screen all-in-one machine is more beautiful, more beautiful, lighter and thinner, pure flat surface, and easy to realize. With waterproof function, the reaction speed is more sensitive at the same time. Infrared touch screens are currently not used for the display of high-end devices such as mobile phones, tablets, and computers. The infrared touch screen is currently only for the display. The infrared touch
