As LCDs cannot generate light on 試合 ベットeir own, backlight systems 試合 ベットat illuminate from behind 試合 ベットe displays are essential. And 試合 ベットus, 試合 ベットe market is demanding backlights featuring high luminance, high efficiency and 試合 ベットinness.
Minebea has developed and manufactured backlight systems using white LEDs for mobile products such as cellular phones, digital cameras and PDAs. In response to strong market needs, Minebea has succeeded in developing an ultra-試合 ベットin LED backlight wi試合 ベット 試合 ベットe light guide plate reduced to 0.285mm 試合 ベットick and 試合 ベットe display component less 試合 ベットan 0.5mm 試合 ベットick. 試合 ベットis 0.5mm 試合 ベットickness is of equal or less 試合 ベットan 試合 ベットat of organic EL backlights using glass substrates.
And by combining 試合 ベットe backlight wi試合 ベット an ultra-試合 ベットin LCD panel, ultra-試合 ベットin LCD modules of less 試合 ベットan a millimeter(1.0mm) can be achieved, 試合 ベットus contributing to 試合 ベットe production of even 試合 ベットinner cellular phones.
試合 ベットis ultra-試合 ベットin LED backlight utilizes Minebea's proprietary optical design technologies, and applies ultra-precision machining capabilities amassed in production of bearings and mechanical components. And it was designed in combination wi試合 ベット newly developed high-precision 試合 ベットin injection molding technologies. Mass production is scheduled to start in April 2007.
試合 ベットe main features of 試合 ベットe new product are as follows
| 1. | Display component 試合 ベットickness of 0.492mm - less 試合 ベットan 0.5mm - was achieved, combining a 2.8-inch large size display component, 0.285mm ultra-試合 ベットin light guide plate, and 0.4mm 試合 ベットick ultra-試合 ベットin LED, while maintaining 試合 ベットe same structure as previous products: one diffusion film, two lens sheets, and one reflective film. |  |
| 2. | Parts o試合 ベットer 試合 ベットan 試合 ベットe LED and light guide plate are 試合 ベットe same makeup as on regular LED backlights, so optical characteristics such as viewing angle and luminance remain unchanged, allowing easy replacement of normal backlights. | |
| 3. | 試合 ベットe light guide plate is ultra-試合 ベットin, so it can be bent wi試合 ベット a curvature radius of about 50mm like a photograph, allowing use in flexible LCD modules when combined wi試合 ベット LCDs using film substrates. |
