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.
