 ☆ ☆): a large outdoor display 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 through a large outdoor display (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 large outdoor display on the screen of high-pressure flushing experiment, and each box for the invasion of water and water spray experiment, to ensure that the water 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 experiments, induced a large outdoor display of outdoor traffic, car large outdoor display, and mobile outdoor display of their work is often in the conditions of vibration, in order to ensure product reliability, the need for vibration experiments. 
 <6> Environment experiments, the blue-pass optical real outdoor environment debug, to ensure that the plant effect and the site effect. 
 ☆ ☆ d): Large outdoor display Features 
 1, blue-large outdoor display existing SMD SMD 3 in 1 SMD SMD mile optional, provide personalized solutions for clients' needs 
 Blue through large-scale outdoor display viewing angle of the selected die can reach above 160 ° angle of elevation up to 80 °, any angle images in this range no distortion, no color cast. 
 3, blue through large-scale outdoor display products, PCB board LSI design, improve the stability of the outdoor display systems. 
 Blue through large-scale outdoor display using advanced high-speed SMT technology, designed to solve the problem of high-density cooling. 
 5, the blue-large outdoor display board to do the coating protection of the three anti-(anti-corrosion, anti-static, moisture), the circuit board is 1.8mm to 2.2mm double-sided fiberglass laminate, which greatly improves the product reliable sex. 
 6, the blue through large-scale outdoor display power to the high stability of the international well-known brand (Cheng linked 5V40A or the CHUANGLIAN 5V40A and the Mean Well power supply) 
 Blue through large-scale outdoor display IC internationally renowned brands Toshiba TB62747AF or accumulate MBI5026 (in extreme environments, parameter fluctuation coefficient is small, Toshiba and accumulation are global stability the most famous brand)
