Abstract
A display device includes a display panel including a plurality of pixels and a display panel driver configured to drive the display panel. Here, the display panel driver is configured to receive input image data, to drive the display panel at a first driving frequency when the input image data corresponds to a moving image, and to select one of a plurality of flicker lookup tables based on the first driving frequency and drive the display panel at a second driving frequency based on the flicker lookup table when the input image data corresponds to a still image.
Claims20
A display device comprising:
- a display panel including a plurality of pixels;
- and
- a display panel driver configured to drive the display panel,
- wherein the display panel driver is configured to receive first input image data for a first frame, to drive the display panel at a first driving frequency during the first frame when the first input image data corresponds to a moving image, to receive second input image data for a second frame next to the first frame, and to drive the display panel at a second driving frequency during the second frame when the second input image data corresponds to a still image,
- wherein the second driving frequency is determined based on a selected flicker lookup table that is selected from among a plurality of flicker lookup tables based on the first driving frequency,
- wherein each of the plurality of flicker lookup tables stores candidates for the second driving frequency, which respectively correspond to grayscales of the first input image data that is driven at the first driving frequency, and
- wherein the display panel driver determines one of the candidates as the second driving frequency based on the selected flicker lookup table.
A method of driving a display device comprising:
- receiving first input image data for a first frame;
- determining whether the first input image data corresponds to a moving image or a still image;
- driving a display panel at a first driving frequency during the first frame when the first input image data corresponds to the moving image;
- receiving second input image data for a second frame next to the first frame;
- determining whether the second input image data corresponds to the moving image or the still image;
- and
- driving the display panel at a second driving frequency during the second frame when the second input image data corresponds to the still image,
- wherein the second driving frequency is determined based on a selected flicker lookup table that is selected from among a plurality of flicker lookup tables based on the first driving frequency,
- wherein each of the plurality of flicker lookup tables stores candidates for the second driving frequency, which respectively correspond to grayscales of the first input image data that is driven at the first driving frequency, and
- wherein one of the candidates is determined as the second driving frequency based on the selected flicker lookup table.
