摘要： A method of driving a light source, a light source apparatus for performing the method, and a display apparatus having the light source apparatus are disclosed in accordance with one or more embodiments. In the method, a plurality of light source strings connected in parallel is driven by applying a driving voltage to a first terminal of the light source strings. A peak current due to a voltage deviation of each of the light source strings is switch-controlled to uniform an average current of the light source strings. Thus, a peak current flowing through light source strings in accordance with a voltage deviation of the light source strings is switch-controlled, so that an average current of the light source strings may be uniformly maintained. Therefore, a voltage deviation is not consumed as power, so that damage to circuit elements due to heat may be prevented.

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 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.
