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

With the rapid development of digital information technology, the overall technology in the urban transportation field has also been effectively improved, and information modernization and intelligence have gradually been realized, and “smart transportation” has gradually been realized from the concept. Based on the background of smart transportation, how to realize the smart display of traffic information is the key. In-depth analysis of the application and advantages of digital signage in smart transportation, aviation, subway and rail transit. Airport flight display application With the rapid development of social processes, the digital construction of urban airports not only assumes the responsibility of aviation infrastructure, but also becomes the central hub of regional economic integration and urban internationalization. The year-on-year increase in passenger throughput and the continuous improvement of airport service quality have placed stringent requirements on real-time information updates and display equipment at the airport. Actually used in airport scenarios, digital signage can be used as a large aviation display screen to realize the intelligent display of information. On the one hand, after being equipped with the CMS messaging system, it can realize the unified scheduling and control of the information released by multiple terminal devices, present flight and boarding gate information in real time, realize flight information guidance, meet the needs of passenger flow information identification, and can also follow up in time. Check-in status of each flight to enhance the passenger’s flight experience; in addition, information such as flight number, remaining flight tickets, city weather and other information can also

The small-pitch LED display has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. It is not reflective for indoor applications, and the display contrast is as high as 5000:1; it is lightweight and ultra-thin, High precision, small space for transportation and use, quiet and efficient heat dissipation. Small-pitch LED display products have a wider color gamut space and faster response speed than ordinary large LED screens, and can realize seamless splicing and modular maintenance of any size. The whole picture played is uniform in color, high-definition lifelike, no abnormal display such as sweat spots and bright lines that are common on ordinary screens, and the picture switching is soft and does not flicker, and the picture quality is very delicate, which is close to the playback effect of a TV. The contrast ratio of 5000:1 can show excellent blackness when the screen is black, and it is the best among similar products. The biggest competitiveness of indoor high-density and small-pitch LED displays lies in the complete seamlessness of the large screen and the natural and true display colors. At the same time, in terms of post-maintenance, the LED large screen already has a mature point-by-point calibration technology. The large screen used for more than one or two years can be used to perform a one-time calibration of the entire screen. The operation process is simple and the effect is very good. When using a small-pitch LED display, pay attention
