Large-scale electroluminescent screens and flexible plastic liquid crystal displays are unveiled in Boston.
At the Society for Information Display (SID) conference in Boston, US, Westaim subsidiary iFire Technology of Canada showed a 17 inch prototype electroluminescent display. The device is the next step in its plans to produce mid-30 inch screen-size panels for the television market.
The company presented three technical papers at the conference explaining the phosphor materials, phosphor patterning techniques and the efficient resonant integrated supply (ERIS) power management system. These allow wide XGA (1280 x 768 pixel) devices in the mid-30 inch range to operate on less than 200 W.
The Pen Tile matrix delivers the same resolution from half as many subpixels and column drivers compared with standard LCD screens, producing the same brightness while using up to 40 per cent less power.
The companies will integrate Viztec's plastic-pixel LCD nanotechnology with FlexICs' ultra-low temperature polysilicon active matrix architecture.
