Die : Our LED display is mainly used Nichia die , USA and China and Opto just CREE Hangzhou Crossland failure rate is very low: in the LED display will begin to assemble the aging failure rate is less than 72 hours in parts per million ; Antistatic ability : LED 's body static test failure mode voltage up to 5000V; Attenuation : 1000 hours , 20 mA at room temperature after the test light , red, green and blue three attenuation should be less than 12% , 10% , 10% ; Brightness: outdoor full color screen , high brightness, such as Japan, PH16 LED full color tube white brightness of 12000CD / m2; maintaining high brightness of the LED case, using a small current (16mA), thus increasing the service life of LED ; Consistency: consistency of wavelength determines the brightness of the display consistency , white balance consistency , color consistency. Generally, there are ± 2.5nm wavelength range and the brightness range of 1:1.18 ; Stable and high performance : no jitter , flicker , connectors loose phenomenon ; Constant current driver : eliminate mosaic , flower block phenomenon ; Good heat dissipation : Good thermal solution , screen table thermostat to maintain 30 degrees or less ; Using the new box: 1 ) , the surface sandblasting , rust play a role ; 2 ) , the metal surface is treated with zinc oxide Qin ensure ten stainless rot ; 3 ) , carried out after treatment with zinc oxide , and then the surface spray treatment ; 4 ) , and finally the surface is acid-resistant resin-coated shoe processing, more effectively prevent the erosion of the atmosphere . |
