Abstract
A display device includes a display panel including a plurality of panel blocks, a block load calculator which calculates block loads of the panel blocks based on an input image data and determines a maximum block load among the block loads, a block load comparing part which generates a first output image data based on the input image data when the maximum block load is less than a critical block load, and a first load controller which generates a first power control curve and generates a second output image data based on the input image data when the maximum block load is greater than or equal to the critical block load.
Claims20
A display device comprising:
- a display panel including a plurality of panel blocks;
- a block load calculator which calculates block loads of the panel blocks based on an input image data and determines a maximum block load among the block loads;
- a block load comparing part that determines if the maximum block load is less than a critical block load, and generates a first output image data based on the input image data when the maximum block load is less than the critical block load;
- and
- a first load controller which generates a first power control curve and generates a second output image data based on the input image data and the first power control curve, when the maximum block load is greater than or equal to the critical block load.
A method of operating a display device, the method comprising:
- calculating block loads of panel blocks based on an input image data;
- determining a maximum block load among the block loads;
- generating a first output image data based on the input image data when the maximum block load is less than a critical block load;
- and
- generating a second output image data based on the input image data and a first power control curve, when the maximum block load is greater than or equal to the critical block load.
