Abstract
A display device includes a display panel including a plurality of pixels and partitioned into a plurality of blocks including at least one of the pixels, a timing controller configured to receive input image data from an outside source and generate scaled image data by scaling the input image data using a scale factor, a data driver configured to generate a data signal corresponding to the scaled image data and supply the data signal to the pixels, and a logic circuit configured to generate the scale factor based on the input image data, first weight data, and second weight data different from the first weight data.
Claims20
A display device comprising:
- a display panel including a plurality of pixels and partitioned into a plurality of blocks including at least one of the pixels;
- a timing controller configured to receive input image data from an outside source and generate scaled image data by scaling the input image data using a scale factor;
- a data driver configured to generate a data signal corresponding to the scaled image data and supply the data signal to the pixels;
- and
- a first logic circuit configured to measure a current flowing through the pixels to generate a global current value, to calculate a load value ratio for each of the blocks, to generate a load value for each of the blocks based on the input image data and the load value ratio, to generate a target current value based on the load value for each of the blocks, first weight data, and second weight data, and to determine the scale factor based on the global current value and the target current value.
