Souk Jun-hyung, Executive Vice President and the head of LCD Business’ Display R&D Center, said that “Our Blue Phase mode is a major evolutionary development beyond conventional liquid crystal modes. Samsung’s development of the technology provides a tremendous opportunity to move image quality of LCD screens much closer to that of a real moving image.”
Unlike today’s most widely used LCD modes such as Twisted Nematic, In-Plane Switching or Vertical Alignment, Samsung’s “Blue Phase” mode does not require liquid crystal alignment layers. Developed with an extremely cost-efficient design, the new Blue Phase mode can make its own alignment layers, eliminating the need of any mechanical alignment and rubbing processes which reduces the number of required fabrication processes, resulting in considerably savings on manufacturing costs. Moreover, the Blue Phase panel reduces the possibility of staining the LCD panel interface whereby pressure on the screen can impair unvarying brightness.
Since many academic and corporate institutions researched this new liquid crystal mode, Samsung has become the first to unveil a commercially viable product prototype using the “Blue Phase” technology. Currently overdrive circuits are applied to each LCD panel to perk up the video image quality in premium LCD TVs, which are driven at 120Hz. The Blue Phase mode features a better response rate, allowing images to be reproduced at 240Hz or higher without the need for any overdrive circuit. The term “Blue Phase” was coined when the technology’s developers observed bluish hues while watching their new liquid crystal mode in operation.
Samsung expects to start in on mass producing its Blue Phase LCD in 2011. The LCD panels will be mainly used in TVs that have need of high-speed video reproduction.    The company is planning to unveil a 15” model of its Blue Phase LCD panel at the SID (Society for Information Display) 2008 international Symposium, Seminar and Exhibition, which will be held in Los Angeles from May 18 to 23.
