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.
Claims20
A data driver comprising:
- a receiver which receives a clock signal and first image data, wherein the first image data is generated by removing a dithering from a dithered original image data and performing a transition minimization coding thereon;
- a transition minimization coding decoder which removes the transition minimization coding from the first image data to generate second image data;
- a dithering adder which restores the removed dithering based on the clock signal and the second image data to generate third image data;
- and
- a voltage generator which generates a plurality of data voltages based on the third image data.
A display apparatus comprising:
- a timing controller which receives first input image data, which is generated by performing a dithering on original image data, and outputs a clock signal and first image data, wherein the timing controller generates the first image data by removing the dithering from the first input image data and performing a transition minimization coding on the first input image data;
- a data driver which receives the clock signal and the first image data, wherein the data driver removes the transition minimization coding from the first image data, restores the removed dithering based on the clock signal, and generates a plurality of data voltages based on image data generated by removing the transition minimization coding and restoring the removed dithering;
- and
- a display panel which displays an image based on the plurality of data voltages.
