Switching DC power supply and the linear power supply different class of stable power supply is switched-mode DC power supply, Linyi LED display its circuit pattern mainly single-ended flyback, single-ended forward, half-bridge, push-pull and full-bridge. The fundamental difference between it and the LED display Linyi linear power transformer is that it does not work in the frequency but in tens of kHz to several MHz. Shandong LED Display Function tube is not working in the saturation region, that is the cut-off switch state; switching power supply, hence the name Shandong full color. Advantages Linyi LED display manufacturers switching power supply is small, light weight, stable and reliable; Linyi LED disadvantage relative to the linear power supply ripple is large (typically ≤1% VO (PP), can do a good dozen mV (PP) or less). Linyi can display its power from a few watts - are the product of several kilowatts. The price of 3 yuan - more than ten million / guns color manufacturer, here are some switching power supplies in general habit Category: Compared with the AV interface because it is no longer Y / C hybrid transmission therefore no longer be isolated and bright decoding Full Color prices, and use separate transmission channels largely avoided within the video equipment generated image signal crosstalk distortion, greatly improved image clarity, but S-Video still be two-way color signal (Cr Cb) chrominance signal mixed all the way C, transmitted and then processed in the display device to decode the Cb and Cr, this number will continue to bring some signal loss and distortion (this distortion is small but in strict Broadcast-quality video equipment under test while still being found), and because of mixed Cr Cb chroma signal bandwidth is consumed there is a certain limit, so S -Video Although relatively good but far from perfect also phase, S-Video Although it is not the best, but taking into account market conditions and other factors, cost and so, it is the most common video interface. LED display, Yasuhiro photovoltaic (certified), sunshine full color provided by Linyi Wang Tai Electronics Co., 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.
