Epistar already started shipping small volumes of mini LED chips for 27-inch gaming LCD monitor backlighting
during the third quarter.
Coretronic also ship backlighting
modules to Ultrabook panel suppliers' factories in China, including AUO in Suzhou, Jiangsu Province, Chimei Innolux Corp.
Vincenzo Ventricelli, director customer marketing, Middle East & Africa, Philips consumer lifestyle, said: "The new Philips LED backlighting
technology is a true milestone in the ongoing evolution of our FlatTV range.
"We knew we needed a strong LED technology with a broad intellectual property portfolio for our new backlighting
products," said Rex Wu, Lite-On associate vice president.
In addition, there is an increasing need for use as backlighting

. However, the service temperature of the sheet cannot exceed 180 F and the light source should never touch the sheet.

module accounts for about 20% of a LCM's total cost, so panel suppliers' revenues are expected to drop as they now ship more open cells to customers.
The keyboard backlighting

on or off only when the keyboard is in use.
It features full-array LED backlighting
using local dimming technology to produce a 2,000,000:1 mega contrast ratio, TruMotion technology for smooth motion images, an Energy Star's 3.0 certification and LG's Intelligent Sensor that adjust the backlight based on ambient light in the room.
* BendiGlo is fiberoptic backlighting
for hard-to-reach areas, allowing illumination of continuous curves around holes and protrusions, such as molded components, pegs, cables or wires, using single-end or lit-to-center techniques.
Unity Opto said that it has seen clear increase of orders for backlighting
