Display device performing unevenness correction and method of operating the display device

Abstract

A display device includes a display panel including a plurality of pixels, a power management circuit configured to generate an analog driving voltage, a correction data memory configured to store a plurality of unevenness correction data sets respectively corresponding to a plurality of analog driving voltage ranges, a controller configured to determine, among the plurality of analog driving voltage ranges, a current analog driving voltage range to which the analog driving voltage output from the power management circuit belongs, to select an unevenness correction data set corresponding to the current analog driving voltage range from the plurality of unevenness correction data sets stored in the correction data memory, and to correct image data based on the selected unevenness correction data set, and a source driver configured to receive the corrected image data from the controller, and to provide the plurality of pixels with data voltages corresponding to the image data.
