Abstract: A display panel driving apparatus includes a data driving part, a data driving part and an off voltage controlling part. The data driving part is configured to output a data signal to a data line of a display panel. The gate driving part is configured to output a gate signal to a gate line of the display panel. The off voltage controlling part is configured to receive a first off voltage and a second off voltage applied to the gate driving part to generate the gate signal, measure a leakage current of the gate driving part, and control the first off voltage based on the leakage current. Thus, display quality of a display apparatus including the gate driving part may be improved.

Abstract: A display apparatus includes a display panel, a first timing controller, a second timing controller and a third timing controller. The first timing controller controls an operation of a first region in the display panel, and generates a reference clock signal. The second timing controller controls an operation of a second region in the display panel, and receives the reference clock signal. The third timing controller controls an operation of a third region in the display panel, and receives the reference clock signal. The first, second and third timing controllers are synchronized with one another in response to the reference clock signal and a state synchronization signal, and operate in one of a plurality of states depending on an operation of the display apparatus.

Abstract: A data driver includes a receiver, a transition minimization coding (“TMC”) decoder, a dithering adder and a voltage generator. The receiver receives a clock signal and first image data which is generating by removing a dithering from a dithered original image data and performing a TMC. The TMC decoder removes the TMC from the first image data to generate second image data. The dithering adder restores the removed dithering based on the clock signal and the second image data to generate third image data. The voltage generator generates a plurality of data voltages based on the third image data.
