A display device comprising a temperature calculating unit detecting a forward voltage drop of the LED used as illumination unit

摘要

A display device with an illumination unit that causes a plurality of LED to emit light as a back-light of a liquid crystal panel that comprises a temperature calculating unit that detects a forward voltage drop of the LED, and calculates the temperature of the LED based on the detected forward voltage drop; and a control unit that controls the emission of light of the LED and/or the display of picture on the liquid crystal panel based on the calculated temperature of the LED.
