Apparatus and methods for low-power driving of a liquid crystal display device

摘要

An apparatus is provided for driving a liquid crystal display (LCD) device including an array of LCD elements arranged in rows and columns, a respective row of LCD elements connected to a respective gate line, a respective column of LCD elements connected to a respective source line. A gate driver circuit is configured to connect to the gate lines of the LCD device and operative to simultaneously drive a group of gate lines during a first time period to thereby transfer charge between the rows of LCD elements connected to the group of gate lines and operative to drive a selected one gate line of the group of gate lines during a second time period. A source driver circuit is configured to connect to the source lines of the LCD device and operative to apply a video voltage to a source line connected to an LCD element in the row of LCD elements connected to the selected one gate line during the second time period. Related operating methods are also described.
