Introduction of COB LED Display technology 

COB LED display using the newest encapsulation technology which is different from DIP and SMD. Is ERALED who has developed this technique in the field of led display and truly master the skill after years of technical practice. We have developed hundreds of products based on COB patent technique, and COB encapsulation with LED & IC in 1 PCB is the key of COB patent technique.

COB LED is short for Chip-On-Board LED, it's one of bare LED chip technologies, which interconnect bare LED chip to substrate by conductive or non-conductive adhesive, and then wire bonding to achieve its electrical connection. COB package is attach number of chips directly to the substrate, then packaged together by silica gel, epoxy resin or other materials.

Comparing to conventional SMD LED display, ERALED COB LED display has the following advantages:

1. COB LED display can save about 30% cost in the application, mainly lie in LED package cost, light engine production costs and the secondary light distribution costs, which is great significance for applications and promotion of semiconductor lighting.

2. In performance, through the rational design and micro-lens molding, COB LED display can avoid the defects of point and glare light also other flaws existed in discrete light source device. It also can add some red chips appropriately, so that to improve the CRI effectively under the condition of without reduce light efficiency and lifetime significantly.

3. In application, COB LED display makes production of lighting manufacturer more simple and convenient, and reduces cost effectively. In production, the existing technology and equipment can support high yield and large-scale COB LED display manufacturing.

4. 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.

5. Ultra-thin ,ultra-light: weight is just 1\3 of traditional led display module, thickness is just 1\5 of traditional led display module ,can save lots of cost on structure ,delivery and so on .

6. Flexible: Flexible ability is one of the excellent characteristics of COB LED displays. So COB LED displays 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 LED display was widely used in airport, station, mall and so on.

7. 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 .

8. High stability: the dead pixel rate of our COB LED displays <0.00005, 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. ERALED’S 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.

9. Multiple protection: waterproof, moisture-proof, anti-dust, anti-static, anti-oxidation, anti UV.

10. Our COB LED display is very different from the traditional LED. All the chip of our module is protected by epoxy resin, no exposed lamp foot in air, so it can be waterproof, moisture proof, 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 -30 degree to +80 degree.

11. Fast cooling: excellent heat dissipation performance and Low light attenuation: Because the COB LED chip is directly dispensed onto the PCB, the area of heat dissipation is wider than SMD with better attenuation. The heat dissipation of the SMD is emitted through the bottom of its fixing

12. Wider and better view angle: 150° view angle in both Horizontally and vertically:

Better viewing angle with higher brightness both indoor and outdoor:

13. 50% energy saving with very low power consumption, low electricity fee, low heat generation, much longer lifetime, long lifetime high brightness and low failure pixels; Save energy with high brightness: ERALED use big size led chip to increase brightness and heat evenly.

14.The COB system allows for a much higher packing density than SMD (SMT), the result being a more compact array giving better uniformity and higher intensity even at a close distance and greater heat dissipation for better stability, reliability and lifespan. COB technology can solve the problem of protection, anti UV, brightness and quality stability. P3mm outdoor COB LED display is our latest COB LED display. We are developing P2.5 & P1.875 outdoor COB LED display now. The outdoor modules don’t need the glass shade, and can be all-weather used.

15.High Brightness: 800-1500nits for indoor, 5000-9000nits for outdoor

16. Shockproof & Dustproof

17. Seamless Splicing: Super High precision: seamless splicing after CNC processing, less than 0.01mm tolerance

18.Front maintenance, front installation available: no maintenance space needed behind the screen;

19.Special anti-electromagnetic interference function

20.COB LED display is the latest in full color product advancement using a state of the art, base of chip surface bonding technique combined with high precision dispensing. The bare LED chip is mounted directly on the substrate on the back of the PCB, then using a special method of welding using a pure gold wire, a bond is made between the base and silicon chip, then finally the COB is packaged together to form the full color module.

21.COB LED display Producing process: The first step of COB package is to cover wafer placement point on the substrate surface by thermal conductive epoxy (usually is epoxy resin mixed with silver particles). Second is put the wafer on the substrate surface directly, then fix wafer to the substrate firmly by heat treatment. Third is to establish electrical connection between wafer and the substrate by wire bonding method.
