Advantages of LED Indoor Fixed COB

Improve Thermal Management Capabilities

LED Chip Adopts Flip Chip Structure

Improved thermal management
Ftip chip structure
The light-emitting chip is 40% larger than the front-end structure
Heat reduction of about 30%

Higher Reliability And Durability

Simplified Structure:Flipping the LED chip onto the substrate reduces solder pins, streamlining the design.

Eliminates Connection Issues:Minimizes electrical/thermal problems caused by traditional pin connections.

Boosts Stability:Improved mechanical and thermal performance ensures long-term reliability.

Durable & Reliable:Enhanced design extends lifespan for demanding LED display applications.

HDR Support

HDR1000 Support：Larger chips combined with updated control systems simplify HDR1000 (1000nits+) support, enhancing visual quality

with striking contrast and vivid colors, ideal for immersive viewing experiences.

Functional Advantages

Vivid content with strong contrast
Flip chip, heat reduction is about 30%.
No arsenic poison, environmentally friendly and safe
Violent content, strong contrast
Full flip chip process
Clear, vivid images

Improve Light Efficiency And Brightness

The full flip-chip process ensures that the light-emitting surface of the LED chip is not blocked by traditional solder joints, and the effective viewing angle is increased from

140° in the upright structure to 170° in the flip-chip structure. The improvement directly improves the overall brightness and color consistency of the display.

Eye Protection Design

Healthy Soft Light

Polymer-Filled COB Design：Reduces pixel gaps and flicker for stable, uniform visuals.
Soft, Glare-Free Glow：Gentle screen emission minimizes harsh glare and eye strain.
Reduce Eye Strain：Low-glare, flicker-free display eases discomfort during prolonged use.
Smoother Visuals：Enhanced image clarity and comfort for long-term viewing.
