For their new 42PF9831D 42in LCD Philips have tackled two common limitations of LCD screens, motion blur and black level performance using ClearLCD technology.

ClearLCD is a technology developed to address two limitations common to LCD – motion blur and black level performance. ClearLCD uses Overdrive Control and Dimmable, Scanning Backlight technologies to tackle motion blur. Overdrive Control increases the voltage to boost the liquid crystals reaction rate thus lowering the response time. Philips’ backlighting technology utilizes ‘hot cathode’ fluorescent lamps which similar to CRT screens allowing pixels to be lit progressively for a far shorter time improving motion sharpness. Deeper black levels and higher contrast are gained through hot cathode lamps ability to dim 30% more than conventional LCD lamps.

The 42PF9831 also features other technologies:

• AmbiLight Surround – fluorescent bulbs shine colored light matching the dominant screen colors from every side of the TV screen.
• Pixel Plus 3 HD – the latest version of Philips’ Pixel Plus system giving a 75Hz refresh rate to remove image flicker
• An MPEG Artifact Meter that adjusts the level of processing required depending on the quality of the incoming signal.
