摘要： A display apparatus includes light source blocks driven as follows in displaying at least one frame (possibly every frame). An image to be displayed includes image pixels. Each light source block corresponds to an image pixels block which is a block of image pixels to be displayed directly opposite to the light source block. For each image pixels block, a block mean value and a block maximum value are determined. A parameter is determined which corresponds to a total luminance of the frame. For each image pixels block, a block representative value is determined which corresponds to the parameter, the block representative value being within a range between the block mean value and the block maximum value inclusive. During the frame, each light source block is driven to provide a luminance which is an increasing function of the corresponding block representative value.

摘要： A light source apparatus includes a light source, a duty determining part, a luminance shifting determining part and a duty compensation part. The light source includes a plurality of light-emitting blocks. The duty determining part determines a duty of light-emitting blocks by using a block representative value obtained from a plurality of image blocks that are divided in accordance with a plurality of light-emitting blocks. The luminance shifting determining part compares block representative values of a previous frame with block representative values of a current frame to determine whether a luminance shifting is generated at an adjacent light-emitting block. The duty compensation part compensates a duty of the adjacent light-emitting blocks when the luminance shifting is generated at the adjacent light-emitting blocks. Thus, the duty of the adjacent light-emitting blocks determined as a block representative value is compensated so that an occurrence of flicker may be decreased.
