Light-emission control circuit |
摘要 |
Light-emitting parts are attached to a light guide plate of a backlight unit so as to be illuminated by the backlight. A measuring unit formed by light-receiving parts is provided on the opposite side of the light guide plate. The measuring unit detects the luminance or color tone of light inside the light guide plate. A control unit subjects the luminance or color tone to feedback control in accordance with a result of measurement.
