Can be seen in some professional video workstation / editing card or high-end professional video equipment DVD players and other appliances have YUV YCbCr Y / BY / BY other markers to identify interfaces wholesale LED color screen, although the labeling method and joint different shape but all refer to the same color port interfaces (also called component video interface). It is usually YPbPr and YCbCr both markings, the former said progressive scan component output, which represents the interlaced component output. Seen from the above relation outdoor color screen, we only need to know the value of Y Cr Cb will be able to get the value of G (ie the fourth equality is not necessary), so the video output and color processing on harmonization ignored poor Cg green leaving only Y Cr Cb, which is the basic definition color output. As the advanced S-Video product color output S-Video transmission color chroma signal C is decomposed into Cr and Cb color screen, thus avoiding the two color mixing and separation decoding process again, but also to maintain the chrominance channels maximum bandwidth, only after the anti-matrix decoding circuit can be reduced to RGB RGB signal imaging, which minimizes the video source to the video signal path between the display image, avoiding the cumbersome transfer process brought outdoor color screen image distortion, so color output interface mode is currently a variety of video output interfaces of the best. AC power supply capable of providing a stable voltage and frequency of the AC power supply, said stable power supply. Shandong full color work done by the majority of domestic manufacturers of AC voltage stability. The following AC power supply with market some brief classification features. Parameter adjustment (resonance) type such power supply, the basic principles of Shandong LED display regulator is LC series resonant, full color manufacturers offer early stage of magnetic saturation regulator fall into this category. Shandong full color display manufacturers it has the advantage of simple structure, without many of the components, full color reliability is quite high voltage range is quite wide, full-color manufacturers interference and strong anti-overload. The disadvantage is that energy consumption, noise, heavy and high cost. Outdoor color screen, Yasuhiro photovoltaic (certified), Weifang color screen provided by the Thai-Hong Electronics Co., Ltd. Linyi. Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) is a leader in Linyi, a display device, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In Hong Thai Optical leadership with the staff warmly welcome all inquiries negotiations to create the Thai macro photoelectric a better future.
