Innovative COB Flip Chip diode technology in LED screens

Author: Martyna Zajdel

LED technology is a rapidly growing segment in the industrial world. Over time, the diodes that are produced become more and more technologically advanced. The created solutions enable the use of LEDs not only in lighting, but also in the production of advanced high-resolution screens, which we will discuss in this article.

Let’s present COB Flip Chip LED the greatest advantages and possible applications. In the article you will find:

What is COB Flip Chip technology

COB Flip Chip technology is an innovative technology in the field of LED diodes. The abbreviation COB comes from the words Chip-On-Board. Literally, it means an integrated circuit placed on a board.

The diodes used in this technology are placed directly on a ceramic, aluminum or copper circuit board. Flip Chip means that the integrated circuit (chip) is inverted. Therefore, the chip’s electrical contacts face down and are directly connected to the substrate. This eliminates the traditional wire connections that were used in earlier generations of LEDs.

Benefits of using a diode

COB Flip Chip technology brings a number of advantages that contribute to its growing popularity. The most important benefits of using this technology include:

higher light efficiency — because the diodes are smaller, their density per unit area can be increased. In this way, COB Flip Chip modules are able to generate more light while consuming less energy,
light seamlessness — the technology ensures a more uniform and consistent light distribution, eliminating "spots" or unevenness in light emission typical of traditional LEDs,
long life — better heat management resulting from the direct connection of the diodes to the circuit board ensures a longer life of the diodes, reducing the risk of overheating and damage,
greater resistance to weather conditions —- the structure is more resistant to shocks, vibrations and extreme temperatures compared to traditional LEDs,
compact size — higher diode density makes COB modules smaller and lighter, which allows for the creation of more compact solutions,
flexibility in design — COB technology allows for greater freedom in designing various forms and shapes of LED modules, which is unattainable for traditional diodes.

Without a doubt, this technology brings many benefits. The initial cost may be higher than in the classic LEDs. However, in the long run, its durability and greater resistance to damage make this investment definitely worth it.

LED screen using COB Flip Chip diodes

COB diodes is the latest achievement in the field of displays. Therefore, thanks to the use of this technology, LED screens can boast, among others:

Undoubtedly, the miniaturization of diodes and the connections between them has contributed to achieving much better quality of the LED screen . You can best see the difference in image quality in the comparison below.

Construction and parameters of a single module

A single module is an element measuring 600 mm wide, 337.5 mm high and 32.5 mm thick. The rear element of the module is made of aluminum, which was shaped in a high-pressure casting process. The front part of the module consists of circuit boards with COB Flip Chip diodes placed on them.

A single board with diodes placed on it is 150 mm wide and 168.75 mm high and only 3 mm thick . The weight of such a tile is also small and amounts to about 150 g.

Each module consists of 8 interconnected boards and additional equipment thanks to which the screens can be connected together to create large-area LED screens. The weight of one module is only 6.5 kg!

Application of LED screens with COB Flip Chip diode

Screens using this modern diode are used in many places that require super-resolution image display. Displays of this type can be found in:

in modern shop window and retail space arrangements,
video and control rooms , e.g. city monitoring rooms, flight control rooms, control rooms of large production halls,
conference rooms,
television studios,
video wall-s,
interactive advertising banners,
scoreboards in stadiums and sports facilities.

In our offer, you will find a product of the latest generation — a COB screen with a 1.86 pixel pitch. Thanks to its enhanced brightness up to 3000 cd/m², it is an excellent solution for shop windows facing outdoors.

Completed installations with LED screens

The future of COB Flip Chip technology

COB Flip Chip technology is currently one of the most innovative directions in the field of microelectronics.

As technology advances and the demand for devices become smaller and more efficient, this technology is likely to become more important.

Future applications of this technology are expected to cover sectors such as medicine, automotive and wearable technologies, providing solutions of unprecedented quality and reliability. Appropriate investment in research and development of this technique could bring a revolution in the way we perceive and use electronics in the next decade.

Summary

To sum up, the technology using COB Flip Chip diodes brings a number of benefits. Using it in LED screens significantly increases the quality of the displayed image and the energy efficiency of the entire installation.

This technology, together with new LED screens, will soon enter to our offer. Thanks to this, the graphic design of events, sports events, and arrangements in shopping malls and offices that we organize will gain a completely new, better expression.
