    Abstract: A driver for a display panel includes a driving time accumulator, a ditherer, and a data signal generator. The driving time accumulator determines an accumulated driving time of the display panel. The ditherer determines an amount of dither based at least in part on the accumulated driving time, and performs a dithering operation on input image data with the determined amount of dither. The data signal generator generates a data signal for the display panel based at least in part on the input image data on which the dithering operation is to be performed.

    Abstract: A method of displaying a stereoscopic image and a display device are disclosed. In one aspect, the method includes first providing a first portion of left eye image data to a plurality of pixel rows during a first non-emission period of a first frame period, wherein the first frame period includes a first emission period having a first emission transition period and a first compensation period. The method also includes second providing a second portion of the left eye image data to the pixel rows during the first emission transition period while sequentially providing the left eye image data to the pixel rows during the first emission period. The method further includes third providing the second portion of the left eye image data to the pixel rows during the first compensation period and driving the pixel rows to concurrently emit light during the first emission period.

    Abstract: A display device includes a display panel, a dither table memory device, a dithering processor, and a display panel driver. The display panel includes a plurality of pixels. Dither tables are stored in the dither table memory device. The dithering processor selects a target dither table corresponding to a grayscale level of input data from among the plurality of dither tables and performs a dithering operation on the input data using the target dither table to generate dither data. The display panel driver drives the display panel based on the generated dither data.

    Abstract: A temperature estimating apparatus includes an average data outputting circuit configured to output average data of image data displayed on a display panel. The temperature estimating apparatus further includes a change amount outputting circuit configured to determine a change amount of the average data, and to output an average data change amount. The temperature estimating apparatus additionally includes a luminance outputting circuit configured to convert the average data change amount to a luminance, and to output the luminance. The temperature estimating apparatus further includes a temperature sensor configured to sense an ambient temperature of the display panel, and to output the ambient temperature. The temperature estimating apparatus additionally includes a current temperature outputting circuit configured to determine a current temperature of the display panel based on a previous temperature of the display panel, the luminance and the ambient temperature.
