Full flip COB product
COB LED displays use full flip-chip technology that is different from SMT LED displays, bringing ultra-small pitch and ultra-large resolution displays to the market and leading the market. The minimum pixel pitch of the COB display can be 0.4mm, making it easy to achieve 8k. Its excellent protection, stability and energy efficiency, coupled with excellent image quality, make it suitable for various occasions, including command centers, conference displays, commercial displays, home theaters, etc.

Ultra-samll Pixel Pitch
Flip-chip COB technology inverts the wafer and directly packages it on the PCB, abandoning the traditional SMD lamp bead bracket and bonding wire, effectively reducing the size of the LED light source, and is especially suitable for small-pitch LED displays. At present, COB displays using real pixels arranged in RGB have been able to achieve stable mass production of products with a minimum dot pitch of 0.79mm. For COB displays that multiplex virtual pixels of pixels, stable mass production of products with a minimum dot pitch of 0.47mm can be achieved.
High stability
In COB packaging, the chip electrodes bond directly to the PCB board without the need for soldering and reflow soldering processes. This approach solves issues related to traditional processes such as virtual soldering, bridging, and wire breaks, shortening the process path. Simultaneously, it reduces thermal resistance, enhances light quality, and achieves high stability. According to third-party testing, the COB defect rate is less than one in a million, reducing the defect risk by 80%.
High protection
COB integrated packaging, fully sealed LED chip structure, hard and smooth display surface, up to IP65 protection level.
Truly anti-collision, moisture-proof, shock-proof, waterproof, dust-proof, fire-proof, anti-static and salt-spray proof.
Wide viewing angle, high contrast
High-performance chips, professional display technology, and point-by-point color calibration. COB displays offer support for high brightness, high grayscale levels, wide color gamut, high contrast, and HDR10 compatibility, ensuring vivid and lifelike image quality with ultimate fidelity.
Front light source
Utilizes optical diffusive particles and a flat packaging mode to achieve surface lightsource display. Effectively suppresses the Moir pattern, resulting in excellent imaging. Incorporates a low blue light visual design to promote eye health.
