Display device

A display device for displaying frames of video information comprising:

• a display panel comprising a plurality of pixel circuits arranged in a pixel matrix, wherein the pixel matrix is divided into regions of n pixel circuits each, where n is an integer of 2 or more;
• a source driver connected to the display panel to provide data signals to pixel circuits in each column of the pixel matrix, wherein the data signals represent a target brightness for each pixel circuit;
• a correction calculation section connected to the source driver for correcting variations in brightness due to nonuniformity of the plurality of pixel circuits;
• one or more memory units connected to the correction calculation section for storing a correction value for each pixel circuit and an average of correction values for the pixel circuits of each region;
• and
• wherein the correction calculation section, for each set of m frames (where m is an integer of 2 or more and where n/m is an integer of 1 or more), corrects a distinct set of n/m pixel circuits within each region using the correction values for the pixel circuits of the corresponding region in each frame, and corrects the remaining pixel circuits in each region using the average of correction values for pixel circuits of the corresponding region in each frame, and wherein over the set of m frames, each pixel circuit in the pixel matrix is corrected with the correction value for a corresponding pixel circuit only once.
