Patent ID: 8379011

Claim:
A display apparatus comprising: a first voltage generator which receives a power voltage from an exterior to output a first driving voltage; a second voltage generator which receives the power voltage to output a second driving voltage; an output timing controller which receives the first and second driving voltages from the first and second voltage generators, respectively, outputs a third driving voltage in response to the second driving voltage, and outputs a fourth driving voltage in response to the first driving voltage; a gamma voltage generator which receives the third driving voltage from the output timing controller to output a plurality of gamma voltages; a first data driver which operates in response to the third driving voltage from the output timing controller to change a first image signal to a first data signal based on the gamma voltages provided from the gamma voltage generator; a second data driver which operates in response to the fourth driving voltage from the output timing controller to change a second image signal to a second data signal based on the gamma voltages provided from the gamma voltage generator; a gate driver which receives a gate-on voltage and a gate-off voltage output from either the first voltage generator or the second voltage generator and sequentially outputs a gate signal; and a display panel which receives the first and second data signals in response to the gate signal to display an image, wherein the output timing controller simultaneously outputs the third driving voltage and the fourth driving voltage.
