Minebea LED Backlight System Achieves a 20% Improvement in LED Luminescence Efficiency
Minebea Co., Ltd. has successfully developed a new LED backlight system featuring high luminance, high efficiency, and ultra thinness - jointly with an LED maker (Nichia Corporation).
Liquid crystal displays (LCDs) are in strong demand these days - for use in such products as cellular phones, car navigation systems, and TV sets. Contributing to this surge in demand are the recent advances in this product. Backlight systems are integral to LCDs - components that cannot generate light on their own. The markets seek backlight systems featuring high luminance, high efficiency, and thinness.
Minebea has developed and manufactured backlight systems for mobile products using white LEDs - such as cellular phones, digital cameras, and PDAs. The recently developed backlight system responds to these strong market needs. Minebea has re-engineered the conventional relationship between the LEDs and the light guide plates to develop a new conceptional LED and the backlight system.
The new backlight system is a combined development achievement of Minebea's proprietary optical design skills, ultra-precision tool machining capabilities, and high-precision injection molding technologies. The Company has started the mass production of this new backlight system since October 2005.
The main features of the new product are as follows:
Compared with the conventional designs, the new product achieves a 20% improvement in LED luminescence efficiency and a luminous efficiency of 76lm/W.
The new product raises the flexibility of LED arrangement. For about 2-inch sizes, it is usable with an LED lamp. The use of multiple LEDs can further raise luminance.
The height of the new LED is 0.5mm, the industry's thinnest. The thickness of the light guide plate is 0.6mm for standard items, but it can be reduced to 0.4mm.
Reference specifications
(Note) Luminance uniformity is the ratio of the maximum and minimum figures of luminance.
