Basic semiconductor digital tube is composed of seven striped light emitting diode chip arrayed in Figure 12. Can achieve the display 0-9. The specific structure "reflector-type", "bar seven-segment" and "monolithic integrated than digital," etc. (1) reflector-type digital pipe is generally made of white plastic with a reflective cavity seven-segment Linyi case led display manufacturers, will stick with a single LED reflector seven mutually reflective cavity position printed circuit board, the center of each reflector cavity bottom is LED chip. Before loading reflector, with pressure welding method on chips and printed circuit connected between the respective metal strip wire or metal aluminosilicate good lead φ30μm display, dropped in the reflector epoxy resin, then with chips printed circuit board and reflector adhesive Linyi led display on the bit, and then cured. Shandong Power LED display Compensation Type - regulator purifier (including precision regulator) which links with the compensation achieve a stable output voltage, Linyi LED display is easy to realize computer control. Its advantage is a good LED display, high voltage accuracy (≤ ± 1%) anti-jamming performance, fast response (40 ~ 60ms), the circuit is simple, reliable work. Disadvantages are: low-frequency oscillation phenomena with computers, Shandong full color PBX nonlinear loads; input-side current distortion degree, low active power factor; Linyi LED display offer an output voltage on the input voltage phase shift. LED display higher requirements for anti-interference function units, Shandong LED display manufacturers offer application is appropriate Shandong led display in the city, when the computer is powered, Linyi LED display must use the computer for about two to three times the total power regulator is to use. Due to a regulation, interference, fast response, affordable, and other advantages, it is widely used. led display, Yasuhiro photovoltaic (certification), the display is provided by Linyi Wang Tai Electronics Co., Ltd. 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.
