BACKLIGHT CONTROL CIRCUIT IN PORTABLE DEVICE |
摘要 |
Disclosed is a backlight control circuit capable of decreasing current applied to an illuminating device or turning off a portion of illuminating devices if an illuminating time exceeds a predetermined reference time when the illuminating device is in a turned-on state, or a thermal emission temperature of the illuminating device is higher than a predetermined reference temperature. Accordingly, it is possible to reduce current consumption and thermal emission of the illuminating device resulting from continuous turn-on states of the illuminating device while using a backlight function. |
