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 timing controller includes a data grouping part that generates a plurality of grayscale groups based on input image data, each grayscale group including n×m grayscales, a grayscale classifying part that generates a plurality of grayscale patterns respectively corresponding to the grayscale groups, a grayscale in the grayscale groups being classified in the grayscale patterns as a first grayscale if the grayscale is higher than a first reference grayscale or as a second grayscale if the grayscale is lower than a second reference grayscale, a pattern comparing part that compares each grayscale pattern with a first pattern including the n×m first and second grayscales, a pattern counter that counts a number of patterns of the grayscale patterns that are substantially the same as the first pattern, and a driving mode changing part that changes a driving mode of a display panel when the number is greater than a reference number.
