A diminutive sized LED

The Bevel-LED is a diminutive sized LED with dimensions 1.2w x1.6l 1.2h, designed to be attached using the Package on Board platform. Coming in this smaller size of 1-3mm enables a small pitch array, giving the best imagery for high PPI and MPI display screens.

Bevel-LED complies the AEC-Q102 qualification standard and qualifies to JEDEC moisture sensitivity level I (MSL Level 1). Bevel -LED is built on Au plated lead-frame. This makes it free of any sulfur corrosion risk, giving it superior corrosion robustness.

Bevel-LED has a high NTSC solution from its high colour gamut display. It employs the PFS/KSF phosphor technology, and this gives a unique narrow band red emission, making the Bevel-LED capable of expressing richer saturated colours.

Integrating the whole design within honeycomb reflectors improves the display brightness significantly. Using the reflector design configuration as shown below in Figure 2, yielded an average brightness of 108,000 lux; max. 135,000 lux with light efficiency rate of 81%.

In a case study that fulfils the Pitch/OD ≥ 2 requirement, pitch being 20mm while OD 9.5mm, the Bevel-LED achieved close to 100% homogeneity. This data proves that the Bevel-LED enables ultra-thin display with OD 7.6mm while still achieving 89% of homogeneity, well above the market requirement of minimum 80%.
