Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. An electronic apparatus, comprising:
an image processing device which generates input image data corresponding to an input image and block luminance decrease rates for a plurality of blocks included in a display area of the input image; and
a display device which displays an image based on data voltages,
wherein the display device includes:
a display panel which includes a compensation area of the display area;
a timing controller which receives the input image data and block luminance decrease rates for the plurality of blocks from the image processing device, the timing controller including:
an average luminance decrease rate calculator which is configured to calculate an average luminance decrease rate of the input image for the compensation area based on the block luminance decrease rates for the plurality of blocks,
a luminance decrease rate calculator which is configured to calculate a luminance decrease rate for the compensation area based on at least one of the average luminance decrease rate of the input image for the compensation area and a reference luminance decrease rate for the compensation area, and
a data compensator which is configured to generate output image data by applying the luminance decrease rate for the compensation area to the input image data; and

a data driver which is configured to provide the data voltages generated based on the output image data to the display panel.
