Abstract
A display device includes: a timing controller which receives image data including high logics and low logics from the outside; a data driver which generates a data signal, based on the image data; and pixels which emit light with a luminance corresponding to the data signal, where the data driver determines an error of the image data, based on a checksum included in the image data.
Claims20
A display device comprising:
- a timing controller which receives image data including high logics and low logics from an outside;
- a data driver which generates a data signal, based on the image data;
- and
- pixels which emit light with a luminance corresponding to the data signal,
- wherein the data driver determines an error of the image data, based on a checksum included in the image data.

A method for operating a display device, the method comprising:
- receiving, by a data driver of the display device, first image data including high logics and low logics from a timing controller of the display device during a first period of a frame period;
- determining, by the data driver, an error of the first image data, based on a checksum included in the first image data;
- generating, by the data driver, feedback information on the determined error and transmitting the generated feedback information to the timing controller;
- and
- changing, by the timing controller, at least one of a level of the first image data and a slew rate of the first image data, based on the feedback information.
