First Amorphous 2.6-inch VGA LCD Panel
9 August 2004 by axxxr Samsung Develops the World's First Amorphous Silicon ''a-Si'' 2.6-inch VGA LCD Panel
Samsung Electronics Co. Ltd.today announced the world's first a-Si (Amorphous Silicon) 2.6-inch TFT-LCD with VGA (300ppi) image quality. Using a-Si technology, mobile phone displays are now capable of projecting the same VGA format found on notebook PCs and desktop monitors. With almost seven times the resolution of a 42-inch high-definition LCD TV at 300 pixels per inch (ppi), an a-Si enabled mobile phone can be used as a high quality mobile TV. Amorphous silicon (a-Si) and polycrystalline silicon (polysilicon or p-Si) are the two main silicon technologies used in the thin film transistors for LCDs. Low-temperature polysilicon can achieve a high degree of integration, making it the method of choice when producing panels that require high resolution. Conventional wisdom has held that structural properties would limit a-Si technology to 150ppi resolution. However, Samsung Electronics engineers completed a 1.94-inch display with qVGA (207ppi) resolution in May of this year, and continued to improve upon its own a-Si technology to achieve VGA resolution for small- and mid-sized display panels. Samsung's latest LCD is a transflective model (200:1 contrast ratio and 150cd/m(2) brightness), which provides sharp images even when exposed to bright summer sunshine. Mass production on existing lines is scheduled to begin in December of this year, giving the company a competitive edge in terms of production cost and supply capability. Samsung will eventually expand the a-Si technology to "smart phones" and mobile phones equipped for digital multimedia broadcasting. Via: //biz.yahoo.com/bw |
