Abstract
A display device includes: a memory configured to store an over-driving lookup table and previous frame block data generated by block averaging previous frame data; an over-driver configured to obtain current frame data from input image data and to generate over-driving frame data for the current frame data by comparing the previous frame block data and the current frame data with reference to the over-driving lookup table; a data driver configured to generate an over-driven data signal based on the over-driving frame data; and a plurality of pixels configured to display an image based on the over-driven data signal, wherein the over-driver is configured to perform an over-driving based on a size of a block divided for the block averaging.
Claims18
A display device comprising:
- a memory configured to store an over-driving lookup table and previous frame block data generated by block averaging previous frame data;
- an over-driver configured to obtain current frame data from input image data and to generate over-driving frame data for the current frame data by comparing the previous frame block data and the current frame data with reference to the over-driving lookup table;
- a data driver configured to generate an over-driven data signal based on the over-driving frame data;
- and
- a plurality of pixels configured to display an image based on the over-driven data signal,
- wherein the over-driver is configured to perform an over-driving based on a size of a block divided for the block averaging,
- wherein the over-driver is configured to perform the over-driving according to a result obtained by comparing a value obtained by dividing a grayscale value of the current frame data by the size of the block with a grayscale value of the previous frame block data.
A method of driving a display device, the method comprising:
- obtaining current frame data from input image data;
- obtaining previous frame block data generated by block averaging previous frame data, and an over-driving lookup table from a memory;
- generating over-driving frame data for the current frame data by comparing the current frame data with the previous frame block data with reference to the over-driving lookup table;
- generating an over-driven data signal based on the over-driving frame data;
- and
- supplying the over-driven data signal to a plurality of pixels,
- wherein generating the over-driving frame data comprises generating the over-driving frame data based on a size of a block divided for the block averaging,
- wherein generating the over-driving frame data comprises generating the over-driving frame data according to a result obtained by comparing a value obtained by dividing a grayscale value of the current frame data by the size of the block with a grayscale value of the previous frame block data.
