Advantage of COB encapsulation led display :
1.Ultra-thin ,ultra-light :weight is just *3 of traditional led display module , thickness is just *5 of traditional led display module ,can save lots of cost on structure ,delivery and so on .
2. 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. We are developing P2.5 and P2 outdoor RGB modules now. The outdoor modules dont need the glass shade, and can be all-weather used.
3. Anti-collision, Resist compression, 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 *5Kg impact per square cm. If there is bad pixel, it is easy to be repaired.
4. Big view angle : close to **0°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 *0CM.
6.High heat transfer capability : SMD and DIP mainly transfer the heat via gel , light legs and pads , heat trans area  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.****5, this result is better than the national standard.
A. Production process : COB LED Display production is no reflow solder paste lights, then the light quality is much better then SMD
B.  With high-end manufacturing equipment: we use advanced ASM automatic welding equipment
C.  Strictly quality control and inspection during the whole process
D.  WQS business philosophy: Provide the best quality material to customer. Such as: the surface finishing of PCB is Immersion Gold, the PCB price is twice than the PCB which was used on traditional LED modules. We use big and better IC chip on our modules, and we choose the better cooling material on the structure
8. Multiple protection: waterproof, moisture-proof, anti dust, anti-static, anti-oxidation, anti UV.
9.Save energy with high brightness :  WQSLED use big size led chip to increase brightness and heat evenly .
