Recently, the breakthrough of COB packaging technology has injected new vitality into the small-pitch LED display market. Large LED screen companies have expanded the scale of the COB small-pitch market, trying to occupy a larger market share and obtain the largest business benefits. Then, it is badly needed in the industry. In the current period of innovation and reform, can COB packaging technology set off a new storm in the field of small-pitch LED displays? And will COB LED display become the future trend?

Small space applications continue to expand technology innovation is imminent.

The higher end product users' pursuit of product display quality and the continuous expansion of their application fields are the fuel-burning agents for LED display manufacturers to accelerate the pace of product research and development, and promote the rapid progress of the LED display industry. The advent of small-pitch LED displays not only brings users more high-definition and comfortable display results, but also brings technological innovation to the LED display industry at that time. With the popularization of small-pitch LED display technology and the reduction of product cost, more and more manufacturers gradually increase the size and pitch of LED display inputs, and the demand for each application field is also increasing, in addition to “dominating” the traditional In areas such as advertising media and Shangxian, with the rapid development of smart cities, small-pitch LED displays have also occupied a portion of market share in high-end applications such as indoor security and conference rooms with strong economic demand.

The continuous innovation in the application of small-pitch led display screens has led to a higher demand for products, and LED display companies have only been able to reduce the distance between lamp beads and are unable to meet the diversified needs of the terminal market. Only new technologies are available. Constantly updating and upgrading can improve the market competitiveness of enterprises and promote the rapid development of the industry.

COB displays a unique charm that strongly helps small pitch products.

The mature use of COB technology has led to a new breakthrough in LED small-pitch display technology. After continuous exploration and research and development, COB Encapsulation technology has finally achieved a breakthrough in all parties and has become the target of the industry's major companies. At the Guangzhou LED Show in 2018, leading companies in the industry, such as Absen and Cathay Pacific, launched the newly developed COB small-pitch display products, which attracted a lot of attention from the industry and became a hot topic in the industry.

COB Encapsulation technology can be widely welcomed by manufacturers in the application of small-pitch display screen products, and it must have its unique charm. First of all, the COB small-pitch LED technology is conducive to the control of the bad spot rate under very small pitches and extremely large amounts of lamp beads, achieving a higher reliability of the product by less than one-tenth of the bad point rate of the SMD surface-mounting process; The COB technology using the chip-level Encapsulation process essentially replaces the two-step process of "surface-mounting the package into the lamp head and the surface-mounting" directly with the package. As a more simplified engineering method, under the same application scale, especially when faced with “smaller and smaller” pixels, the cost change is more controllable; as the development direction of the future LED display industry, small pitch products. The smaller crystal grains are not a proposition to bypass, and to integrate smaller LED crystal grains, it is clear that the COB Encapsulation technology is more suitable than the traditional engineering route of “first lamp bead rear surface mount”. Under the background of falling prices of mainstream surface-mount LED products, COB technology has undoubtedly become a key development point.

PREMTECO LIMITED has produced the Innovative 4K COB LED Display. Fully breakthrough product restrictions and lead the industry's new trend.

Excellent Color Contract Ratio

The regular black SMD LED has a color contrast ratio of 5,000:1. However, our high-tech COB LED reaches a much higher color contract ratio up to 10,000:1. The color of our COB LED screen looks amazing.

Seamless Connection & 16:9 Aspect Ratio

The screen is gapless. Meanwhile, when we build a LED screen with 2K, 4K, 8K, or some other resolutions, we can still have a 16:9 screen aspect ratio.

Extraordinary Visual Effects

We adopt great PCB design and high quality LED material. With the high refresh rate(up to 3,840Hz) and gray scale(up to 14bits to 24bits), the LED display can bring us amazing visual effects. The light from our COB LED looks softer to our eyes. Meanwhile, when the COB LED screen is playing videos or images, the visual impact is more exquisite.

Strong Module for More Secure Installation & Maintenance

When the dust, or other dirt on the LED modules, you can clean it with duster easily. Meanwhile, the LED won't get damaged by slight collision during the installation and transportation.

Larger Viewing Angle and Lower Power Consumption

More than 170 degrees of ultra-wide viewing angle delivers head-turning visual effects. And the power consumption is lower than regular LED display products.

Higher Pixel Pitch

With the innovation technology and years of experience, now we could produce the world’s finest pixel pitch: P0.9 and P0.7. And soon we could do P0.5 or even smaller pitch LED display.

Longer Lifespan

Thanks to the flip chip technology wireless packaging technology, the heat dissipation for the LED is better, thus the LED works more secure. With the unique feature of the COB LED ( great reliability and high level surface protection), the LED display ensures the perfect performance for more than 8 years.

Technological innovation is a constant topic in the LED display industry. Only by continuously introducing new technologies and new products can we ensure the successful completion of industrial upgrading. The emergence of COB technology, with a small pitch LED products to a higher level, to bring a better user experience for the end market, but we can not predict, there will be sophisticated technology in the future waiting for the LED display. The screen industry will bring surprises to users, let us wait and see!
