摘要： A backlight driving circuit for a display apparatus includes a receiver, a signal modulation detector and a driver. The receiver receives a clock signal and a brightness data signal by a serial transmission and in response to an enable signal. The brightness data signal is synchronized with the clock signal and includes brightness information. The signal modulation detector detects a modulation of the brightness data signal, based on at least one of the clock signal and the enable signal, and outputs a control signal based on a detected result thereof. The driver receives the brightness data signal, in synchronization with the clock signal, selects one of the brightness data signal and a predetermined reference brightness data signal in response to the control signal, generates a driving voltage using the selected brightness data signal, and provides the driving voltage to the backlight unit to control the brightness of the backlight unit.

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.
