This paper describes a highly versatile “System LCD” which has been developed for mobile applications. A key feature of the display is a multi‐format capability to enable both the color depth and the spatial resolution to be dynamically controlled according to the application. This advanced functionality is realized by integrating a novel source‐driver, binary‐driver and clock‐generator onto the panel. A 3.7″ LCD with three principal display formats has been successfully fabricated using low temperature CG‐Silicon technology. The power consumption in each format has been measured at 14mW for VGA/Full‐color, 8mW for QVGA/Full‐color and 2mW for QVGA/Monochrome. We believe this versatile display technology, which combines both high performance and low power consumption, will be essential for the next generation of mobile products.
