Samsung turns on 240Hz Blue Phase LCDs

The new technology does not require liquid crystal alignment layers, unlike today's most widely used LCD modes such as Twisted Nematic, In-Plane Switching or Vertical Alignment.

The Blue Phase mode can make its own alignment layers, eliminating the need for mechanical alignment and rubbing processes, according to the manufacturer.

Samsung explained that this reduces the number of required fabrication processes, resulting in savings on production costs.

Additionally, Blue Phase panels can reduce the possibility of "bruising" the LCD panel interface, whereby pressure on the screen could impair uniform brightness.

Samsung executive vice president Souk Jun-hyung said that the devices offer a "tremendous opportunity" to improve the image quality of LCD screens so that they can more closely display moving images.

Overdrive circuits are currently applied to each LCD panel to improve the video image quality in premium LCD TVs, which are driven at 120Hz.

The Blue Phase mode features a superior response rate, allowing images to be reproduced at 240Hz or higher without the need for any overdrive circuit.

Samsung is planning to unveil a 15in model of the device at the Society for Information Display 2008 International Symposium, Seminar and Exhibition in Los Angeles from 18 to 23 May.
