Our commitment to innovation is showcased through advanced technology that meets the growing need for high-resolution, bright, and versatile outdoor displays.

What are COB LED display modules?

COB LED Display Modules, also known as COB LED Display Panels or COB LED Display Tiles, are key components used in the assembly of larger LED displays, which you might see used for advertising, information display, or as part of a digital signage system. These modules are small sections of an LED screen that contain an array of LEDs. Let’s break down the concept to understand it better:

Basic Components

  • LEDs (Light Emitting Diodes): Small, efficient lights that can emit a variety of colors. They are the primary visual element of the display.
  • Circuit Board: LEDs are mounted on a circuit board that provides the electrical connections required for operation.
  • Driver ICs: Integrated circuits that control the brightness and color output of the LEDs.
  • Housing: A protective casing that holds the circuit board and LEDs, often designed to facilitate heat dissipation and protect the components from environmental factors.
COB (Chip-on-Board) is a type of LED display packaging technology. LED light-emitting chips are directly bonded to the module board with high precision and connected to driver components on the module board via specialized media to protect the light-emitting surface. COB packaging eliminates the two key procedures of turning LED chips into lamp beads and reflow soldering as compared to standard SMD packaging.

COB LED Display Module Advantages:

Brightness and low power consumption

Suitable for higher brightness than other LED modules (such as SMD and DIP), COB LED screens have the smallest chip spacing. COB doesn’t take up space. This also indicates that it consumes very low power and is energy efficient.

Excellent heat dissipation

The COB LED display employs an efficient heat-dissipation base made of aluminum or ceramic. This helps the COB LED chips be mounted closer together, which improves heat dissipation.

Outstanding protection ability

The COB LED screen uses a coating technology that protects it against water, moisture, dust, UV, and impact. It also delivers the best optical performance and long-term stability.

Super lightweight

COB LED monitors use 0.4 mm, 0.6 mm, 1.0 mm, and 1.2 mm PCBs as the core board, according to clients’ requirements. It reduces the weight to less than 1/3 of the traditional value, thereby reducing structural, transportation, and engineering costs.

Anti-impact and crush

The surface of the COB LED display cover is smooth and hard, and it wraps the chip wall in a flat position, inlaid between PCB boards. As a result, the screen becomes more impact- and wear-resistant.

  •  Wide viewing angle

COB LED display has a viewing angle of 175° to 180°, which provides a better optical diffuse color effect.

  • Long working time

COB LED display has a triple protection treatment that makes it resistant to water, dust, rot, electrostatic, oxidation, UV, and so on. The screen can work normally under temperatures ranging from minus 30 degrees to 80 degrees.

COB LED Display Technology Development 2023

According to some data, in the first half of 2023, the sales of fine pixel LED (P2.5 and below) screens in China reached 7.33 billion, which is a little bit more than last year. COB technology had a big part in this, as its sales and display area grew a lot, much more than the other types of fine pitch LED screens. This shows that COB technology has changed from a small and special type of screen to a big and common one. It is ready to grow even more in technology and industry.

This change is related to how COB technology has improved and found new uses. Since it started in 2012, it has become better and better over the years. It has become cheaper and more popular, and it has more advantages than other types of LED screens. It is more reliable, more energy-saving, and more suitable for mini/micro LED technology. It can also meet the needs of new LED display products, such as LED all-in-one machines, business meetings, and smart education panels. These products need high-quality screens that are very clear and bright. Many COB brands have done very well in these markets.
