摘要： Controller unit includes local dimming logic board and controller board. Local dimming logic board generates local dimming signals in response to image data received from external device. When boost-worthy portion of image data is found to satisfy predefined boosting conditions, local dimming logic board increases luminance value of backlight dimming signal supplied for corresponding boost-worthy area portion of image data. Controller board receives image data from local dimming logic board, and gamma converts peripheral area data corresponding to peripheral area of image data into converted image data using compensating gamma conversion different than that used for image data of backlight boosted area so that luminance of peripheral area adjacent to boosting area is decreased by use of compensating gamma conversion in place of normal or reference gamma conversion. Decreased luminance substantially counter compensates for increased luminance due to light from spreading into peripheral area from adjacent boosted area.

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.
