DISPLAY DEVICE AND METHOD OF CONTROLLING ITS BRIGHTNESS

摘要

A temperature difference estimating apparatus determines, from image signals, a temperature difference estimating value by using a temperature estimating value representing a temperature at the outer periphery of a PDP display screen and a reference value representing a temperature, at the outer periphery of a PDP panel, output from a panel outer periphery temperature setter, and uses a controller and a brightness controller to control the brightness of an image displayed on a display unit according to this temperature difference estimating value.
