Compared with in-line and SMD, it is characterized by saving space, simplifying packaging operations, and has an efficient thermal management method.The COB package is chip on board, which is to stick the bare chip on the interconnection substrate with conductive or non-conductive adhesive, and then perform wire bonding to achieve its electrical connection. If the bare chip is directly exposed to the air, it is susceptible to pollution or artificial damage, which affects or destroys the function of the chip, so the chip and the bonding wire are encapsulated with glue. People also call this form of packaging soft package.Fine pixel pitch LED DisplayParametersModelP1.26 COBPixel Pitch1.26 mmPixel Density623,268 Pixels/SQ.MModule Size (W*H)304mmW*342mmHModule Pixels(W*H)240*270 PixelsPixel ConfigurationCOB PackageDriver Mode1/45 ScanLED LAMP TYPECOBCabinet Size(W*H*D)608mmW*342mmH*48mmD; Scale is 16:9Single Cabinet Area (Square meter)0.2079 SQ.MNet Weight5 KGS (11.0231 LBS)Cabinet Resolution480*270 PixelsColor Scale65,536 DegreeView Angle(H/V)140/120 degreeBrightness (Max White balance)about 550 NitPower ConsumptionMax: 600Watt/SQ.M Average: 180Watt/SQ.MOperating Temperature-30°C----+60°COperating Humidity10% RH--95% RHLift Time≥100,000 HoursMTBF10,000 HoursWhole Display Flatness≤0.2mm Junctureframe Frequency Source25-60 Hz/sRefresh Rateabout 3,840 Hz/SControl Distance100meter, Fiber is 20 KMLED Control SystemNova Star or ColorlightOperating SystemWindows 7 (32 and 64Bit),Windows 8, Windows 10Protection GradeIP41Maintenance wayFront MaintenanceThisseries LED modules, receiver card, power supply are all front maintenance, cabinet with front installation holes has fully described the strength of its light weight, meet the needs of small space or where the needs of the cabinet thickness, enhanced the vision of the space as well as its visionary effect.
