COB Mini/Micro LED Displays: Ultra-Fine Pitch & Superior Performance

As LED technology continues to evolve, three distinct approaches have emerged as popular choices for video wall applications: COB LED (Chip-On-Board LED), Micro COB LED Display, and Micro LED. These technologies each offer unique advantages while differing in several key aspects.

COB Mini/Micro LEDs now achieve flawless colors, ultra-fine pixels, and cinema-grade contrast. Flip-chip packaging enhances heat dissipation, light efficiency, and lifespan—making it ideal for high-resolution displays.

Key features include ultra-small pixel pitch, flip-chip design, common cathode technology, and COB integration. Flip-chip eliminates gold wires, enabling better heat dissipation and finer pixels—used in Sony’s Crystal LED and Samsung’s The Wall.

Flip-chip COB technology sets a new standard, offering higher brightness, reliability, and seamless ultra-fine pitch displays. As the tech matures, COB Mini/Micro LEDs are shaping the future of high-end visual experiences.

COB LED integrates multiple chips directly onto a PCB, enabling compact, high-brightness displays with efficient heat dissipation. Micro LED uses microscopic (<100μm) self-emissive pixels for ultra-fine pitch and precise control, delivering superior contrast and color accuracy.

COB LEDs deliver exceptional brightness through densely packed chips, ideal for high-lumen applications. Micro LEDs surpass in contrast and color precision with their microscopic self-emissive pixels, producing more vibrant imagery.

What is Micro COB LED Display

A micro COB (Chips on Board) LED display is an advanced display technology that utilizes a cutting-edge LED packaging method for LED light engines. Specifically, COB technology involves mounting LED chips directly onto the substrate on the back of the circuit board, which enhances durability and performance.

To achieve this, ultrasonic welding technology is used to conduct lead bonding of the LED chip, ensuring strong and reliable electrical connections. Afterward, resin glue is applied to encapsulate the lamp position, thereby protecting the LED chip from environmental factors such as moisture, dust, and physical damage.

As a result, micro COB LED displays offer superior brightness, energy efficiency, and longevity compared to traditional LED displays. Additionally, this technology enables finer pixel pitches, making it ideal for high-resolution applications like indoor screens, control rooms, and high-end commercial displays.

Larger Viewing Angle

COB package adopts the class of surface luminescence, so the viewing angle is wider, so that the COB encapsulated micro-pitch LED display screen has a vertical and horizontal bidirectional 170 ” wide viewing angle, which ensures that any angle of viewingno color deviation, the images and videos can always be displayed perfectly.
