Abstract
A display device including a first pixel area configured to display an image at a first refresh rate, and a second pixel area configured to display an image at a second refresh rate lower than the first refresh rate. During a frame period in which pixel data is updated for the pixels in the second pixel area, the polarity of the data voltage is inverted. A driving method using the display device is also disclosed.
Claims16
A display device comprising:
- a display panel including a plurality of data lines, a plurality of gate lines, and a plurality of pixels;
- a data driver electrically connected to the plurality of data lines and configured to output a data voltage having a polarity indicated by a polarity control signal;
- a gate driver electrically connected to the plurality of gate lines and configured to output a gate pulse synchronized with the data voltage;
- and
- a timing controller configured to control operation timing of the data driver and the gate driver, and to generate the polarity control signal to control polarities of the plurality of pixels,
- wherein the display panel comprises:
- a first pixel area configured to display an image at a first refresh rate;
- and
- a second pixel area configured to display an image at a second refresh rate lower than the first refresh rate, and
- wherein during a frame period in which pixel data is updated for the pixels in the second pixel area, the polarity of the data voltage is inverted, causing the polarities of the pixels in the first pixel area and the pixels in the second pixel area to be inverted.

A method of driving a display device, the method comprising:
- driving pixels in a first pixel area of a screen of the display device at a first driving frequency to display images in the first pixel area at a first refresh rate;
- driving pixels of a second pixel area of the screen at a second driving frequency to display images in the second pixel area at a second refresh rate lower than the first refresh rate;
- and
- inverting polarities of the pixels in the first pixel area and the pixels in the second pixel area during a frame period in which pixel data is updated for the pixels in the second pixel area.
