Advantages of LCD

LCD mainly includes TFT, UFB, TFD, STN and other types of LCD. The structure of LCD is to place liquid crystal in two parallel glasses. There are many vertical and horizontal small wires between the two glasses. The direction of rod crystal molecules is controlled by power on, and the light is refracted to produce a picture.   High brightness, The higher the brightness value of the array LCD, the brighter the picture will be without blurring. Advanced display can display clearer and higher brightness product features. We rely on polarization filters and light itself. With the practice of natural light in all corners of the world, a series of liquid crystal filters must be parallel.   The higher the contrast, the more colorful and saturated the color will be, and the higher the plane will be. On the contrary, the color change is low, the color display is poor, the image will be flattened, and the color change value is different, even higher. Compared with CRT imager, LCD dot matrix LCD display has the advantages of zero radiation, low power consumption, small heat dissipation, small volume, accurate image recovery and high character visualization.   The view of “big view” simply means that the view in front of the screen can be seen the larger the sight distance, the easier it will be; As long as the viewer changes the viewing position slightly, the picture may become blurred.

Advantages and precautions for use of small-pitch LED display

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

Digital Signage Advantage characteristics

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
