摘要：

A new (12 + 1)-channel block-addressing driving method and a cost-effective drive IC have been successfully developed. The power consumption of the new block-addressing driving method is nearly 50% less than that of the conventional block-addressing method. The panel integrated dc/dc converter for the voltage of transistor-turning-off (V-off) enabled us to reduce the size and the manufacturing cost of the driver IC. On the basis of these technologies, a 1.89 '' active-matrix liquid crystal display with 240 x RGB x 320 pixels was fabricated with a data driver, a dc/dc converter for V-off, a gate driver, and a level shifter for a gate driver. The power consumption of the panel using the low-voltage driving liquid crystal is typically 13 mW.
