Abstract
A display device and a method of driving a display device, where the display device includes a display panel which is driven at a driving frequency and on which pixels are disposed, a gate driving circuit configured to apply a scan signal to the pixels, a data driving circuit configured to convert image data to generate a data voltage and apply the data voltage to the pixels, and a timing control circuit configured to receive an image signal from an external source, convert the image signal, and output the image data to the data driving circuit.
Claims19
A display device comprising:
- a display panel configured to operate at a driving frequency and on which pixels are disposed;
- a gate driving circuit configured to apply a scan signal to the pixels;
- a data driving circuit configured to convert image data to generate a data voltage and apply the data voltage to the pixels;
- and
- a timing control circuit configured to receive an image signal from an external source, convert the image signal, and output the image data to the data driving circuit,
- wherein the timing control circuit is configured to compensate for a luminance of the image data based on the driving frequency and an original luminance value of the image signal to generate compensated image data and to provide the compensated image data to the data driving circuit.
A display device comprising:
- a display panel configured to operate at a driving frequency and on which pixels are disposed;
- a gate driving circuit configured to apply a scan signal to the pixels;
- a data driving circuit configured to convert image data to generate a data voltage and apply the data voltage to the pixels;
- and
- a timing control circuit configured to receive an image signal from an external source, convert the image signal, and output the image data to the data driving circuit,
- wherein the timing control circuit is configured to compensate for the image data using a luminance compensation value determined based on the driving frequency and an original luminance value of the image signal and to provide the compensated image data to the driving circuit driver, and
- wherein the luminance compensation value is configured to decrease, based on at least one of the driving frequency and the original luminance value decreasing.
A method of driving a display device including a display panel which is driven at a driving frequency and on which pixels are disposed, a gate driving circuit that applies a scan signal to the pixels, a data driving circuit that converts image data to generate a data voltage and apply the data voltage to the pixels, and a timing control circuit that receives an image signal from an external source, converts the image signal, and outputs the image data to the data driving circuit, the method comprising:
- generating, by the timing control circuit, compensated image data for the image data of a first frame based on a first luminance compensation value during the first frame;
- and
- generating, by the timing control circuit, compensated image data for the image data based on a second luminance compensation value corresponding to the driving frequency and the original luminance value of the image signal, based on at least one of the driving frequency and the original luminance value of the image signal changing in a second frame subsequent to the first frame.
