Abstract: A backlight unit for a display device and a control method for the same is presented. The backlight unit comprises: a plurality of light source units arranged in a matrix form; a light source controller adapted to supply a control signal for controlling a brightness of the light source units; and a plurality of light source drive units adapted to supply different driving signals to different light source units based on the control signal. The control signal is generated based on optical crosstalk between neighboring light source units.

Abstract: The invention relates to a control circuit (2) for controlling an electrical signal (4) over a load (6) such as a deflection circuit of a Cathode Ray Tube, comprising a first transistor (8) for switching the electrical signal (4) over the load (6), wherein the load (6) is coupled to a collector (10) and an emitter (12) of the first transistor (8), and wherein the control circuit (2) also comprises a resonance circuit (14) which is coupled to a basis (16) and the emitter (12) of the first transistor (8) for driving the first transistor (8), a power supply (18) which is coupled to the resonance circuit (14) for driving the resonance circuit (14), a pulse generating circuit (20) which is coupled to the power supply (18) and the resonance circuit (14), and a processing unit (24) with a memory unit (26). Furthermore the invention relates to a method for adjusting a control circuit according to the invention.
