how to fix hand sanitizer dispenser

System advantages 1. Centralized control and centralized management: Through the WAN network remote control, there is no need to manually change the card or insert the card, so that different places, different audiences, and different time periods can play different advertising information content. Software upgrades can also be operated remotely, without manual presence. 2. Real-time release: Immediately release emergency information, emergencies, and insert media files to achieve the simultaneous release of bank foreign exchange, fund interest rates, policies and regulations, promotional activities, weather forecasts, clocks and other instant information. 3. Stability: Efficient and stable embedded design, plug and play, no virus infection. 4. Split screen display: At the same time, multiple information combinations such as audio, video, pictures, letters, etc. are played to realize the free adjustment of any position of videos, pictures, and subtitles, which solves the contradiction that only advertising is less concerned or only entertainment programs have no advertising value. 5. Information security: The use of special pricing technology can control the broadcast of all non-audited programs, effectively ensuring the safety of outdoor media transmission. 6. HD playback: Supports high-definition playback of MPEG1, MPEG2, MPEG4, WMV9, H.264 and other media (except for the two formats of rm and mkv, other media formats are basically supported.). Internet function 1. Support all existing IP networks, support various network protocols and provide service quality assurance. 2. Real-time information release: rolling subtitles, pictures, video clips, etc. 3. The network updates the broadcast content without manual replacement. 4. The playback terminal can

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
