BIAS CURRENT SUPPLY UNIT, A LIQUID CRYSTAL DISPLAY DEVICE, AND A METHOD FOR DRIVING THE LIQUID CRYSTAL DISPLAY DEVICE CAPABLE OF IMPROVING IMAGE QUALITY

摘要

PURPOSE: A bias current supply unit, a liquid crystal display device, and a method for driving the liquid crystal display device are provided to reduce the power consumption of the liquid crystal display device by reducing a bias current for driving an output buffer unit of a data driving circuit unit.;CONSTITUTION: A line counter(151) counts the number of gate lines by synchronizing with a gate start pulse and generates a control clock. A control signal generating unit(153) generates a control signal according to the control clock. A bias current output unit(155) outputs a bias current according to the control signal.;COPYRIGHT KIPO 2013;[Reference numerals] (125) Output buffer unit; (151) Line counter; (153) Control signal generating unit; (155) Bias current output unit
