TFT LCDs Employ Chip-On-Glass Technology

Using a low-temperature poly-silicon technology (LTPS) thin-film transistor LCD, the 8.4" LTM08C342S display has a resolution of 800 x 600 pixels and the 10.4" LTM10C306S, 1024 x 768 pixels. LTPS technology uses a cell composed of poly-silicon, which is a material capable of achieving higher electron mobility compared to the amorphous silicon found in typical active matrix LCDs in use today. The peripheral driver circuits that control the display are integrated directly onto the substrate, eliminating the need for externally mounted driver ICs. This technology is said to reduce component count by up to 40% compared to amorphous silicon LCDs, as well as reducing by 95% the number of connections needed for the LCD module system . Poly-silicon technology allows smaller circuit pitch by patterning circuits directly onto the glass to support high resolution levels.
