A display device and a method for correcting an image of the display device are disclosed. In one aspect, the display device includes a display panel including a plurality of pixel lines configured to be selected as at least one of data insertion lines and data deletion lines. The display device also includes an image corrector configured to receive input image data, select the data insertion lines and data deletion lines when the input image data represents an image including a static image block, insert second image data corresponding to the data insertion lines into the input image data, and delete first image data corresponding to the data deletion lines from the input image data so as to generate corrected image data including a shifted static image block.

Display device and method for correcting image of display device

An display device includes a display panel including a plurality of pixels; a scan driver configured to provide scan signals to the pixels; a data driver configured to provide data signals to the pixels; a look-up table (LUT), wherein an efficiency curve indicating a relationship between an accumulated driving time and an efficiency value is stored in the LUT; a lifespan register, wherein an efficiency changing region for deriving the efficiency value of each of the pixels from the LUT is stored in the lifespan register and the lifespan register is configured to accumulatively store deterioration data of the pixels; and a controller configured to derive the accumulated driving time from the lifespan register, to update the efficiency changing region and the LUT based on the accumulated driving time, and to convert input image data into output image data using the efficiency changing region and the LUT.

Organic light emitting display device and method of driving the same

In a data driver, an inverter inverts a first data signal from a first group of data signals. A converter includes first and second converting circuits. The first converting circuit converts a second data signal included from second group of data signals into a first gamma voltage. The second converting circuit has a circuit configuration inverted with respect to the first converting circuit. The second converting circuit converts the inverted first data signal into a second gamma voltage. An output buffer stores the first and second gamma voltage outputs from the converter and then outputs them. Thus, although gamma voltage is interfered from the coupling between a signal line and a gamma voltage line, a user can have normal images regardless of s the gamma voltage variation. The present invention relates to charge-trapping memories in the application of display panels.
