Toshiba Unveils New Polysilicon TFT LCD

BOSTON, May 21 -- Toshiba Corp. said that it has developed the world's first large flexible liquid crystal display, opening the way to the display of images on curved screens and moving toward the long-term goal of foldable LCDs. The new display is a full color, 8.4-inch super-slim low-temperature polysilicon active-matrix TFT LCD supporting SVGA resolution.

Toshiba produced the device by developing technology to achieve an extremely thin glass substrate, the layer on which TFTs are formed, and attaching it to a flexible sheet. Displays using this technology can be manufactured at the normal process temperature. The new display can be flexed in all directions and bent to form a curve with a radius of curvature as high as 20 cm. The display was announced at the Society for Information Display 2002.
