Liquid crystal display device and control method thereof that drives image data based on detected temperature and intensity of external light

摘要

A liquid crystal display device includes: an emphasis conversion section performing an emphasis conversion process on image data of a current frame, based on an emphasis conversion parameter corresponding to a combination of image data of the current frame and image data of a frame immediately preceding the current frame; driving sections causing a liquid crystal display panel to display an image corresponding to the image data on which the emphasis conversion process has been performed; a temperature sensor detecting an in-device temperature of the device; an optical sensor detecting a light intensity of incident external light into the panel; and a control section calculating a temperature of the panel, based on the in-device temperature and the light intensity, and changing the emphasis conversion parameter to be used in the emphasis conversion process in accordance with the calculated temperature of the liquid crystal panel.
