Abstract
A display device includes a display panel including sub-pixels, a data driver for providing the sub-pixels with a data voltage generated using a gamma reference voltage, a driving controller for controlling the data driver, and a memory storage for providing the driving controller with black data voltage information of a first area of the display panel according to a driving frequency, a dimming level, and a temperature of the display panel.
Claims20
A display device comprising:
- a display panel including sub-pixels;
- a data driver configured to provide the sub-pixels with a data voltage generated using a gamma reference voltage;
- a driving controller configured to control the data driver;
- and
- a memory storage configured to provide the driving controller with black data voltage information of a first area of the display panel according to a target luminance corresponding to a given driving frequency, a dimming level, and a temperature of the display panel.

A method of driving a display device including a data driver and a display panel including sub-pixels, the method comprising:
- acquiring, from a memory storage, black data voltage information according to a target luminance corresponding to a given driving frequency, a dimming level, and a temperature for a first area of the display panel;
- calculating an area-specific correction value for a second area of the display panel using the acquired black data voltage information, and
- controlling data voltage generation of the data driver using the area-specific correction value to vary the target luminance corresponding to the given driving frequency, the dimming level, and the temperature for the second area of the display panel.
An electronic device comprising:
- a display device configured to display an image;
- a power device configured to supply power for an operation of the display device;
- and
- a processor configured to supply signals to the display device,
- wherein the display device includes:
- a display panel including sub-pixels;
- a data driver configured to provide the sub-pixels with a data voltage generated using a gamma reference voltage;
- a driving controller configured to control the data driver;
- and
- a memory storage configured to provide the driving controller with black data voltage information of a first area of the display panel according to a target luminance corresponding to a given driving frequency, a dimming level, and a temperature of the display panel.
