20090015542 | METHOD AND DEVICE FOR CONTROLLING THE BACKLIGHTING OF A FLAT SCREEN - Electronic circuit designed to control the level of lighting produced by light diodes in a flat screen. The circuit uses a PDM modulator in order to generate a control signal (Vc) with a number of pulses by period that depends on the desired level of lighting. The advantage is to reduce the energy in the low frequencies. | 01-15-2009 |
