![]() ![]() The most outstanding feature of GOB LED is the high protection ability which can prevent the displays from water, humidity, UV, collision, and other risks effectively. But in the future, the cost can be lowered with the corresponding technology developing. The maintenance needs to be operated with special equipment, leading to high maintenance costs and difficult operation.Īs the reject ratio is high, so the production cost is higher than SMD small pixel pitch LED a lot. There may be problems caused by modularization as high modularization can result in inconsistency in color.īecause each lamp bead will be potted glue separately, the surface evenness can be sacrificed. There is no first step for selecting the light beads, resulting in poor consistency in color and brightness. There are still many details that can be improved during production, and production costs can be lowered by technological progress in the future. (2)Suitable for small pixel pitch LED DisplayĪs the chips are directly connected to the PCB board, the distances between each unit are narrow so as to decrease the pixel pitch to provide customers with clearer images.Īs we mentioned above, the structure of COB LED is simpler than SMD and GOB, so the packaging process is relatively simple, too.Īs a new technology in LED industry, COB LED has had not enough experience of being applied in small pixel pitch LED displays. The simple structure gives it advantages over the other two types of heat radiation. One of the aims of this technology is to deal with the problem of heat dissipation of SMD and DIP. (2)Mask can be sensitive to the changes in the environmentįor instance, the mask may plump up when the surrounding temperature is high, affecting the visual experiences.īesides, the mask may be yellowing or turn white after using a period of time, which will degrade the viewing experiences too. ![]() For example, deadlights and broken lights can happen frequently in a humid environment and during transportation. The functions of anti-moisture, waterproof, dustproof, anti-crash still have the potentials to be improved. (1)Protection ability waiting for further improvement Even you put it under running for 24 hours, the working life can be up to 10 years.Īs this technology has been developed for many years and has been rolled out in the whole industry so the production cost is relatively low. The common service life of SMD LED display is 50,000 to 100,000 hours. ![]() No need for idling time, and has a quick response to the signal, and can be widely used for high-accurate tester and digital displays. So it is not easy to be damaged.īesides, the placement machine is advanced to make the soldering accurate and reliable so as to ensure the lamp lights are not easy to apart from the board. The lamp light is potted with epoxy resin, which brings a solid protection layer to components inside. Though it does not need much electricity, it can still achieve high brightness. The power consumption of single LED lamp light is comparatively low from about 0.04 to 0.085w. It can serve as advertising screens for both indoor and outdoor applications well, and also the predominant type of LED display industry. The brightness level is appropriate, and the display is anti-glare. SMD LED display has high color uniformity that can achieve high color fidelity. ![]()
