摘要： There is provided a method of boosting a local dimming signal. In the method, it is determined whether or not local dimming signals, which are applied for individually driving light source blocks per frame, satisfy boosting conditions. Then, a predetermined local dimming signal corresponding to at least one of the light source blocks is boosted to a reference luminance value when the local dimming signals continuously satisfy the boosting conditions, and the boosting luminance of the predetermined local dimming signal at the reference luminance value is gradually decreased after a light adaptation time of an observer's eye. When the luminance of light source blocks that are boosted is gradually decreased before the light adaptation time or luminance of light source blocks that will be boosted is gradually increased to the light adaptation time, power consumption required to boost the light source blocks may be decreased.

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： In a machine-implemented method of local dimming a light source of a light source block for driving the light source block to provide a plurality of image regions with light, duty ratios of a first light source and a second light source adjacent to the first light source are initially determined by using a first target luminance value of a first image region closest to the first light source and a second target luminance value of a second image region closest to the second light source. The initially determined duty ratios are compensated by using a target luminance value of a remaining image region excluding the first and second image regions among the image regions receiving the light generated from the first and second first light sources. The first and second first light sources are driven by using the compensated duty ratios.
