8.4 in. and 10.4 in. Low-Temperature Poly-Silicon TFT LCDs

The LTM10C306S low-temperature poly-silicon (LTPS) thin film transistor (TFT) liquid crystal displays (LCD) for portable computers is 8.4 in., offers a resolution of 800 x 600 pixels, and is 4.9 mm thick. The 10.4-in. LTM10C306S offers a high-resolution of 1,024 x 768 pixels, resulting in a bright, razor-sharp display. Lower power consumption and higher durability make the LTPS TFT LCDs suited for portable applications ranging from digital cameras, computer displays, and other information equipment.

LTPS technology incorporates a cell compromised of poly-silicon, a material capable of achieving higher electron mobility than the amorphous-silicon found in typical active matrix and other LCDs today. Therefore, peripheral driver circuits that control the display can be integrated directly onto the substrate, eliminating the need for externally mounted driver ICs around the display panel. This enables an overall reduction in component count by as much as 40% compared to amorphous-silicon TFT LCDs and a 95% reduction in the number of connections required in the LCD module system. It also alleviates many of the physical limitations imposed on LCDs that require peripheral driver circuits.

In addition, poly-silicon technology allows a smaller circuit pitch by patterning circuitry directly onto the glass to support high-resolution levels. All combined, poly-silicon technology allows for thinner, brighter, lower power, high resolution, less complicated TFT LCD modules.
