Title:
IMAGE DISPLAY APPARATUS, DRIVER APPARATUS, AND BACKLIGHT UNIT
Document Type and Number:
WIPO Patent Application WO/2012/014537
Kind Code:
A1
Abstract:
The objective of the invention is to provide an image display apparatus wherein a plurality of light emitting elements serving as light sources of the backlight are driven in a time division manner and the number of components can be further reduced. An image display apparatus comprises a driver apparatus (22) and N element sequences which are first to N-th sequences (where 2 ≤ N) and each of which includes one or more light emitting elements (23). The driver apparatus is used to cause the element sequences to emit light in such a manner that light emission-capable periods do not overlap each other, and the obtained light is used as the backlight for an image display. The driver apparatus comprises: a power output circuit (22a) that outputs a light emission power to be used for the light emitting elements to emit light; and a switch mechanism (22b) that switches, in response to an arrival of the light emission-capable period related to the element sequence of the K-th sequence (where 1 ≤ K ≤ N), the output destination of the light emission power in the power output circuit to the element sequence of the K-th sequence.
