Abstract
Discussed is a display device including a frequency calculator configured to calculate a driving frequency of a previous frame and compare the driving frequency of the previous frame and a threshold driving frequency, a compensation data calculator configured to calculate compensation data based on a comparison result of the frequency calculator that the driving frequency of the previous frame is lower than the threshold driving frequency a data storage configured to provide the compensation data corresponding to the calculated compensation data to an image data output unity, and the image data output unit configured to output the compensation data to a data driver.
Claims20
A display device comprising:
- a frequency calculator configured to calculate a driving frequency of a previous frame, and compare the driving frequency of the previous frame and a threshold driving frequency;
- a compensation data calculator configured to calculate compensation data based on a comparison result of the frequency calculator that the driving frequency of the previous frame is lower than the threshold driving frequency;
- a data storage configured to provide the compensation data corresponding to the calculated compensation data to an image data output unit;
- and
- the image data output unit configured to output the compensation data to a data driver.
A method of performing a variable refresh rate mode of a display device, the method comprising:
- Calculating a driving frequency of a previous frame for the display device, and comparing the driving frequency of the previous frame and a threshold driving frequency;
- calculating compensation data based on a comparison result of the comparing that the driving frequency of the previous frame is lower than the threshold driving frequency;
- providing the compensation data corresponding to the calculated compensation data to an image data output unit of the display device;
- and
- outputting the compensation data to a data driver of the display device.
A timing controller for a display device having a variable refresh rate (VRR) mode, the timing controller comprising:
- a frequency calculator configured to calculate a driving frequency of a previous frame, and compare the driving frequency of the previous frame and a threshold driving frequency;
- a data storage configured to store image data;
- an image data output unit configured to output the image data received from the data storage to a data driver of the display device;
- and
- a compensation data calculator configured to calculate compensation data based on a signal from the frequency calculator.
