摘要： A backlighting assembly for an LCD display is divided into a plurality of selective dimming areas each having a respective plurality of light generating blocks. A plurality of driving units supply power to the light generating blocks. The light generating blocks are grouped into light source groups. Each of the driving units supplies power to at least one light generating block in a first light source group and a second light generating block in a second light source group but not to all the light generating blocks in any one light source group. Light generating blocks connected to a same driving unit may be distributedly arranged to be nonadjacent to one another. Plural driving units are used to fully power a brightly lit one dimming area, thereby reducing the loads on the individual driving units and preventing overheating.

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.
