RGB MicroSideLED / Big on light, small on space
The compact LED package is only 0.6 mm high and accommodates three colored chips that can be individually controlled and together cover more than 100% of the NTSC color space. The results on the display are vibrant colors of exceptional brilliance. Depending on the white point, the luminous efficacy is 35 to 40 lm/W - an impressively high efficiency that comes from the high-power thin-film (red) or ThinGaN chips (green, blue). The green chip provides the highest luminance for this color on the market with a value of 1000 mCd from an operating current of 20 mA. An extremely low-profile out-coupling window enables very thin light guides to be used. This is essential for super flat displays.
Notebook backlighting has to function reliably at 60°C for more than 15,000 hours. This is no problem at all for MicroSideLED. The LED is mercury-free and RoHS compliant. Its 6-lead design ensures efficient heat dissipation and enables the LEDs to be connected in series. "Our RGB MicroSideLED combines exceptional brightness with an extremely low-profile form factor", said Winfried Schwedler, Marketing Manager for LCD Backlighting at OSRAM Opto Semiconductors. "Its special SMT package is suitable for standard solder processes and allows display manufacturers to specify high-power LEDs for super-compact displays."
