Virtual pixel display in each of the LED light tube (virtual pixel) are the same around the three-color LED luminous tubes pixel color screen, LED light tube in the same amount, the virtual pixel display than the actual pixel display mode three-color pixel increase fourfold. As a result of pixel multiplexing method to improve the display efficiency display points, the virtual pixel display in the display image, the same number of points than the actual pixel display four times the clarity improved Virtual pixel monochrome display text display When, because they can not take advantage of the relationship between adjacent pixels display, thus indicating ability to distinguish the real back to its corresponding pixel display. For example: 4mm spacing virtual pixel screen, the display text is equivalent to the real 8mm pixel pitch display. Switching AC power supply which applies high-frequency pulse width modulation, the difference Linyi LED display and general switching power supply is its output to the input side must be above the frequency, the same phase of the AC voltage. Shandong LED display its output voltage waveform has a quasi-square wave, trapezoid wave, sine wave and other outdoor color screen, uninterruptible power supply (UPS) on the market in Shandong Shandong full color full color manufacturers offer storage power and deprived them chargers, is an AC power supply switching regulator is good, control functions, easy to implement intelligent LED color screen wholesale, Linyi LED display is very promising AC power supply. However, because of circuit complexity, higher prices, so the promotion is slow. Indoor color screen, color screen Liaocheng, Linyi Hong Thai photoelectric provided by Thai-Hong Electronics Co., Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) strong, credible, in Linyi display equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Hong Thai Optical into the brilliant and you work for a better future!
