Features
?
COB encapsulation,?is the abbreviation for Chip On Board , totally new encapsulation technical which is different from DIP and SMD,COB encapsulation with LEDS & ICS in 1 PCB is the key of COB patent technique .
Compared with traditional dot matrix ,DIP and SMD , COB LED display has the following significant advantages:
?
1. A breakthrough for outdoor small pitch ?:COB technology can solve the problem of protection, anti UV, brightness and quality stability. P3.0 outdoor RGB is our latest modules. The outdoor modules don’t need the glass shade, and can be all-weather used.
?
2.?Ultra-thin ,ultra-light :weight is just 13 of traditional led display module , thickness is just 15 of traditional led display module ,can save lots of cost onstructure ,delivery and so on .
?
3. Anti-collision, Anti-stree, wear-resisting: ?COB LED Display is directly put the LED chip on the PCB, then wire bond ,dispensing ?,The surface of COB LED is very smooth and hard. The lamp surface can withstand 65Kg impact per square?mm. If there is bad pixel, it is easy to be repaired.
?
4. Big Viewing angle : close to 180°view angle in H & V , then it can catch eyes from every angle.
?
5. Flexible: Flexible ability is one of the excellent characteristics of COB modules. So COB modules can be shaped canopy screen, arc shaped screen, circle shaped screen and wave shaped screen. It is the ideal choose for bars and nightclubs. COB screen is with seamless splice, simple structure, and lower price which less than FPCB and traditional LED shaped screen. For example, P4 RGB modules can be made into circle shaped screen with min diameter 50CM. Because of the excellent performance, COB module was widely used in airport, station, mall and so on.
?
6. Hight heat transfer capability : SMD and DIP mainly transfer the heat via gel , light legs and pads , heat trans area m is small ,the heat will be focused on the chip , this will cause serious optical attenuation phenomenon and dead lights after working for a period . COB LED Display is directly put the chip on PCB , heat on the chip will transfer via copper foil on the PCB , and our PCB has strict process requirement , price of PCB is SMD and DIP twice times at the same specification .COB LED Display has transferred the heat out of the chip , that is why feel hot on touch .
?
7. High stability: the dead pixel rate of our COB modules <0.00005, this result is better than the national standard.
?
8. Multiple protection: waterproof, moisture-proof, anti dust, anti-static, anti-oxidation, anti UV.
COB LED module is very different from the traditional LED. All the chip of module is protected by epoxy resin, no exposed lamp foot in air, so it can be waterproof, mositureproof, and anti-static; at the same time, it is very easy to be cleaned. The surface treatment of PCB is immersion Gold, after special treatment process, the LED module can be anti-oxidation and anti UV. All our modules can be work during -45 degree to +80 degree.
?
9. Save energy with high brightness : ?With big size led chip to increase brightness and heat evenly
