DRIVER APPARATUS OF LIQUID CRYSTAL DISPLAY CONTROLLING COLOR CHARACTERISTICS EASILY

摘要

PURPOSE: A driver apparatus of a liquid crystal display is provided to control color characteristics easily with low cost. CONSTITUTION: According to the driver apparatus of a liquid crystal display including a plurality of pixels arranged in a matrix, a signal control part(600) processes an image signal from the external and then outputs it. A gray voltage generator part(800) generates a plurality of gray voltages. A voltage generator part generates a plurality of bias voltages having different amplitudes. And a data driver part(500) selects a voltage corresponding to the image signal among the plurality of gray voltages as a data voltage. The image signal includes red, green and blue data. The data driver part includes an output amplifier supplying the bias voltage to a red, green and blue pixel.
