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 of LCD TV screens with high levels of color reproduction.

Neon, fluorescent, and incandescent light sources can be used for backlighting. However, the service temperature of the sheet cannot exceed 180 F and the light source should never touch the sheet.

The keyboard backlighting is automatically adjusted using ambient light sensors based on the amount of light in the room, while motion sensors detect the proximity of a user's hands to turn the backlighting on or off only when the keyboard is in use.
