摘要：The present invention relates to a method of improving the luminous efficiencyof a sequential-colour matrix display, the display being driven using an addressingmethod of the pulse width modulation or PWM type. This method comprises, for each

pixel of a subframe, the following steps: comparison of the pixel colour value of thepreceding subframe with a reference value so as to provide an overlap value dependingon the period of overlap with the current subframe; if the pixel colour value of thecurrent subframe less the overlap value gives a positive value, a time offset is added tothe pixel colour value of the current subframe; if the pixel colour value of the currentsubframe less the overlap value gives a negative value, the pixel colour value of thecurrent subframe is forced to be zero. The invention applies to LCOS or LCD displays.
