Driving device, display apparatus having the same and method of driving the display apparatus

摘要

A driving device includes an output timing controller (130) which controls an output timing of a first driving voltage (AVDD1) and a second driving voltage (AVDD2) respectively generated from a first voltage generator (110) and a second voltage generator (120). A third driving voltage (AVDD3) output from the output timing controller is provided to a first data driver (150) and a second data driver (160), and also provided to a gamma voltage generator (140) to generate a plurality of gamma voltages (V GMMA ). Accordingly, a reverse electric potential between the third driving voltage (AVDD3) and the gamma voltages (V GMMA ) is prevented from being generated in the first and second data drivers, therefore, preventing the first and second data drivers from being damaged.
