<P>PROBLEM TO BE SOLVED: To adequately detect a temperature of an LED as lighting with a low cost configuration and adequately perform various processings based on the detected temperature. <P>SOLUTION: A display device containing a lighting unit with multiple LEDs as a backlight of a liquid crystal panel includes a temperature computing unit to detect a forward voltage drop of the LEDs and compute a temperature of the LEDs based on the detected forward voltage drop, and a control unit to control the light emission of the LEDs and/or a video display on the liquid crystal panel based on the computed temperature of the LEDs. <P>COPYRIGHT: (C)2012,JPO&INPIT |
