Abstract: A driving device of a display apparatus includes: a gate driver, a gate on voltage modulator, and a signal controller. The gate driver includes a plurality of gate driving circuits, each of the gate driving circuits being configured to: generate a gate signal according to a gate control signal, and apply the gate signal to at least one gate line. The gate on voltage modulator is configured to: modulate a gate on voltage according to a modulation control signal, and generate a first modulated gate on voltage. The signal controller is configured to generate the modulation control signal and the gate control signal. At least one of the plurality of gate driving circuits includes an amplifier configured to: receive the first modulated gate on voltage, and output a second modulated gate on voltage including substantially the same waveform as the first modulated gate on voltage.

Abstract: A data driver includes a gamma unit, a digital-to-analog converter, and an output buffer. The gamma unit receives at least one reference voltage, and generates a first gamma reference voltage corresponding to a first sub-pixel and a second gamma reference voltage corresponding to a second sub-pixel using the received at least one reference voltage. The digital-to-analog converter receives the first and second gamma reference voltages from the gamma unit, and generates a first gamma data value corresponding to the first sub-pixel using the first gamma reference voltage and a second gamma data value corresponding to the second sub-pixel using the second gamma reference voltage. The output buffer outputs a first frame including the first gamma data value and a second frame including the second gamma data value. The output buffer outputs the first and second frames in a repeated manner for every predetermined number of frames.
