Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.

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
