COB, Chip on Board, is an advanced packaging technology that bonds the bare chip directly onto the circuit board. The traditional SMD technology has many advantages when compared with the alternative. First of all, it can improve the brightness and contrast of the product remarkably due to the higher chip density and more concentrated light source. Second, COB technology performs better in terms of heat dissipation. Due to the fact that a bare chip is directly bonded to the heat-dissipation substrate, it can decrease the probability of gathering heat effectively and extend product life. In addition, COB technology is able to enhance the protective performance of products. Because of the simplicity of the packaging process, component exposure is reduced; as a result, products have better waterproofing, dustproofing, and impact resistance.

The following are a few products based on COB technology:

MCOB Series

All these above-mentioned products have excellent display effects and reliable performances and can be applied in several fields. First, commercial display: COB technology can provide a clear display of images and videos to the commercial displays, and make the advertisement content more vivid to attract people's attention. Second, the COB displays assure to bring high brightness and high-contrast images in command and control centers and monitoring systems to perform information accurately. Moreover, COB displays are also widely used for conference halls, large-scale performances, and stage background, presenting an excellent display effect with stable performance, and hence a perfect visual experience for various events and meetings.

In a word, COB technology has huge application prospects in the display field for its high brightness, high contrast ratio, excellent heat dissipation performance, and protection capability. In commercial displays, surveillance systems, or large-scale events, COB technology can meet users' demands for display effects. Through the unremitting development and optimization of technology, future COB displays will play a more and more significant role with their unique advantages in many aspects and bring a more breathtaking visual experience.
