 ☆ ☆): electronic advertising screen quality assurance 
 Photoelectric blue through to world-class precision testing instruments and production equipment to ensure good quality of the product. After years of development, quality control and management processes to maintain its leading position in the domestic LED industry. 
 1, the selection of blue electronic advertising screen (LED): 
 <1> the same display of red, green, blue light-emitting diodes each with a grade (the same height, the same wavelength). 
 <2> the ratio of the brightness of the display of red, green, blue tube in strict accordance with R: G: B = 3:6:1. 
 <3> in cooperation with domestic and international famous brands, chip Silan, Opto Tech of Taiwan, the United States CREE or Japan Nichia. 
 2, the reliability of experiments: 
 Blue company in order to avoid hidden defects in the production, design, and developed a series of reliability test. 
 <1> semi-finished electrical properties experiment in the semi-finished modules before the sealing compound, after QC testing is completely OK, all the products, electrical aging at high temperatures of at least 48 hours. 
 <2> finished aging experiments, the finished module installed in the LED cabinet, and to simulate the scene of the entire screen assembly, trouble-free after 72 hours can be shipped by aging test. 
 <3> water experiments, the increase in electronic advertising screen on the screen of high-pressure flushing experiment, and each box, the invasion of water and water spray experiment, in order to ensure the waterproof effect. 
 <4> anti-corrosion experiments, blue company to ensure that the circuit board after repeated treatment, anti-corrosion and reliability of the chassis in the production process must be the salt fog experiment. 
 <5> vibration the experiment, For the The outdoor traffic induced electron advertising screen, the-vehicle electronic advertising screen, and the the work of of the movable LED electronic advertising screen, because of its are often in the under the conditions of of vibration, In order to ensure the product reliability, must be carried out the the vibration experiment . 
 <6> Environment experiments, the blue-pass optical real outdoor environment debug, to ensure that the plant effect and the site effect. 
 ☆ ☆): electronic advertising screen Features 
 1, the existing patch of blue through electronic advertising screen SMD 3 in 1 SMD SMD mile optional to provide personalized solutions for clients' needs 
 The blue electronic advertising screen viewing angle of the selected die can reach more than 160 °, elevation angle of 80 °, any angle images within this range no distortion, no color cast. 
 3, Blue through electronic advertising screen product PCB board LSI design, improve the stability of the system of electronic LED advertising screen. 
 4, Blue electronic advertising screen uses advanced high-speed SMT technology, designed to solve the problem of high-density cooling. 
 5, the circuit board of the Blue-pass electronic advertising screen to do a the coating protection of and three defenses, (anti-corrosion, anti-static, moisture-proof), circuit board for the the 1.8mm ~ the 2.2mm the double-sided glass fiber copper clad laminate, which greatly to improve the a reliable of the products sex. 
 6 blue electronic advertising screen power high stability of the international well-known brand (Cheng linked 5V40A or the CHUANGLIAN 5V40A and the Mean Well power supply)
