Epson Introduces high-temperature polysilicon TFT panels for 3LCD front projectors compatible with wide XGA
Seiko Epson has begun volume production of 0.74 inch (1.9 cm diagonal) and 0.56 inch (1.4 cm diagonal) high-temperature polysilicon (HTPS) TFT panels for 3LCD front projectors compatible with wide XGA (WXGA). The new panels offer greater light efficiency by employing the latest D7 design rule process, which achieves higher aperture ratios. This technology enables users to view bright wide-screen images on large screens.
The new panels are compatible with 1280 x 800 dot resolution, the most common level of resolution for WXGA, which offers data volumes approximately 1.3 times higher than XGA (1024 x 768 dots). For Internet browsing the technology enables users to simultaneously view multiple browsers or display long pages on a split screen to reduce the stress of scrolling. Compatibility with high-definition screens makes the technology suitable for displaying not only PC data, but also wide screen images such as high-definition playback and content.
Commercialization of WXGA panels in two types – 0.56 inch and 0.74 inch – will enable the creation of WXGA compatible projectors in the 2000 to 3000 lumen class or higher.
