Patent ID: 8760379

Claim:
A driving circuit for a display panel, comprising: a driving voltage generator configured to output a gate-on voltage, a gate-off voltage, a common electrode voltage, and a plurality of reference voltages; and a gray scale voltage generating unit configured to dynamically select based upon user viewing angle from one among the plurality of reference voltages generated by the driving voltage generator as a selected gamma reference voltage and to generate a plurality of gray scale voltages based on the selected gamma reference voltage, wherein a highest reference voltage corresponds to a widest viewing angle and a lowest reference voltage corresponds to a narrowest user viewing angle, wherein the gray scale voltage generating unit comprises: a voltage selector for selecting and outputting one from among the plurality of reference voltages provided by the driving voltage generator as the selected gamma reference voltage; a voltage distributor for generating a plurality of distribution voltages using the selected gamma reference voltage; a multiplexer unit for selecting some of the plurality of distribution voltages and outputting the selected distribution voltages as gray scale selection voltage; and a gray scale voltage output unit for generating a plurality of gray scale voltages using the gray scale selection voltages and outputting the plurality of gray scale voltages, and wherein the common electrode voltage is independent of the plurality of reference voltages.
