发明名称 BACKLIGHTING DEVICE AND IMAGE DISPLAY APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a backlighting light device that prevents load variation even when a backing light scan driving is executed, and to provide an image display apparatus. <P>SOLUTION: The backlighting device includes: a light-emitting part (200) including a light-emitting means (210) for each of a plurality of light-emitting regions that are divided at least in a vertical direction and changing the light-emitting means to be a non-light-emitting state in the vertical direction in response to scanning of an image; and a driving part (300) including at least one or more driving means (310-340), each of which drives the light-emitting means. The diving means has voltage applying means that apply common voltage to needed to drive the multiple light-emitting means driven by each of the driving means, and drives the light-emitting means in the light-emitting regions whose vertical directional positions are different. <P>COPYRIGHT: (C)2011,JPO&INPIT
