Abstract
A display device includes a display panel including a plurality of pixels, and a panel driver configured to drive the display panel. The panel driver receives input image data at a variable input frame frequency, stores the variable input frame frequency as a previous frame frequency by monitoring the variable input frame frequency, determines a reference frequency based on the previous frame frequency, determines a reference luminance as a luminance of the display panel at the reference frequency, and adjusts data voltages applied to the plurality of pixels such that a luminance of the display panel at the variable input frame frequency becomes the reference luminance.
Claims20
A display device, comprising:
- a display panel including a plurality of pixels;
- and
- a panel driver configured to drive the display panel,
- wherein the panel driver is further configured to:
- receive input image data at a variable input frame frequency;
- store the variable input frame frequency as a previous frame frequency by monitoring the variable input frame frequency;
- determine a reference frequency as a value between a minimum frequency and a maximum frequency of a variable frequency range of the variable input frame frequency based on the previous frame frequency;
- determine a reference luminance as a luminance of the display panel at the reference frequency;
- and
- adjust data voltages applied to the plurality of pixels such that a luminance of the display panel at the variable input frame frequency becomes the reference luminance.
