(Press Release)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.



"Samsung has built its proprietary amorphous silicon gates into the LCD panel, maximizing the efficiency of LCD design, controllers and module processing," said Vice President Kim Hyung Guel of the Mobile Display Business Team. "This superior technology will be initially targeted for PDA phones and other top-end mobile phones that require high image quality."

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.
