Large screen display unit from the technical implementation can be divided into DLP splicing, PDP splicing, DID LCD stitching. Currently, DLP way because of its low brightness, volume and large, life is short, higher maintenance costs defects, technically backward. PDP splicing with high brightness, high contrast, small size, etc., but the long-term continuous use tends to screen burn, show a picture color distortion, dark block and so on. Therefore, for a long time, plasma technology is mainly used to use and does not require frequent applications training room big screen continuous operation of the display works, but not suited for applications requiring uninterrupted work of the control system. We use special materials and processes, using the latest scientific and technological achievements and rely on many years of professional experience in technology, gave birth to the most advanced large-screen LCD technology. Selection of units consisting of large-screen system is one of the key parts of the system related to the overall level of quality big screen. For this reason, we recommend to your side using DID LCD splicing unit. Can fully meet the needs of users to work long hours. While using special stitching unit structure to ensure the overall system to achieve high quality stitching, large-screen high-level, solid and reliable, does not occur variants. DID large screen display unit features stitching unit DID LCD panel technology using full color outdoor LED large screen, with unique advantages in addition to large-screen system Auditorium equipment as described in the first chapter, but also has all the advantages of DID LCD panel: an excellent display performance due to the liquid crystal display after each point in the received signal has maintained that the color and brightness, constant light, rather than as a cathode ray tube display (CRT) that highlights the need to constantly refresh. Therefore, the liquid crystal display high quality and absolutely does not blink, the eye fatigue to a minimum. Samsung LCD splicing screen, using professional DID display technology, brightness up> 700cd / m, and has a high brightness uniformity; contrast ratio of up to 3000: 1; 10000K color temperature, still perfect display even in sunlight, the screen is clear and bright; high color saturation and reduction; supports VGA ~ UXGA, WXGA resolution signal interval; has two sides to 178 degrees ultra-wide viewing angle. Indoor full color LED screen | Wuhan mosaic project (certified) | big screen provided by the Wuhan Engineering Co., Ltd. Jiuhua video.
