Abstract (en)
[origin: EP0961259A1] The signal generator (1) has a video signal source (VIDEO-E) receiving a pixel synchronization signal (Fpx) from an oscillator (4), which is coupled to control stage with a frequency divider (5) and a pulse width modulator (6), providing a pulse width modulated control signal (Ftr) for a local pixel synchronization signal generator (14), within the control device (2) for the liquid crystal display (LCD). An Independent claim for a control device for a liquid crystal video display screen is also included.
