Display apparatus for controlling the brightness values of a plurality of light sources and method of controlling the same

摘要

A display apparatus (1) comprising a display panel (20) and a plurality of light source units (47) corresponding to the blocks of the display panel (20), each of the plurality of light source units (47) having one or more light source elements (45) includes a light source driver (150) for separately driving the light source units; a brightness level controller (113) for controlling brightness levels of image data applied to the display panel (20) by blocks so that the difference in brightness level between adjacent blocks and/or between the blocks of the different frame but of the same spatial position falls within a predetermined range; and a controller (130) for controlling the light source driver (150) to drive the light source units (47) based on the controlled brightness level.
