LIQUID CRYSTAL DISPLAY AND CHAGE SHARE CONTROL METHOD THEREOF

摘要

PURPOSE: A liquid crystal display device and a charge share control method thereof are provided to efficiently reduce power consumption in a data driving circuit by controlling a charge share according to a data transition. CONSTITUTION: A data driving circuit supplies a data voltage to data lines for each horizontal period to maintain a source output enable signal with a low logic state and selectively shares a charge to short a positive output channel and a negative output channel according to a logic level of a charge share control signal for each horizontal blank period to maintain the source output enable signal with a high logic state. A charge share control circuit(24) analyzes a gradation value of data and a polarity control signal line by line and determines the logic level of the charge share control signal based on the analysis result.
