HIGH PERFORMANCE REFLECTIVE LIQUID CRYSTAL LIGHT VALVE USING A MULTI-ROW ADDRESSING SCHEME

摘要

A system for partitioning a column in a display device, e.g. a liquid crystal display (LCD) into n sub-columns, wherein each sub-column drives 1/n of the total cells associated with the column, thereby reducing the current required to drive the columns. By increasing the number of column drivers and associated column conductors in the display, the capacitive loading on each column driver is proportionately reduced, thereby enabling the use of smaller-area, and thus less expensive, column driver devices. The display rows can be arranged in groups to provide 1/n 'effective' rows, wherein each row driver drives n-sub columns.
