Patent ID: 6940474

Claim:
A method for processing video signals for display on a display panel comprising a matrix array of cells which could only be “ON” or “OFF”, wherein the time duration of a video frame is divided into N sub-fields during which the cells can be activated, each sub-field comprising at least an addressing period and a sustaining period, the duration of which corresponding to the weight associated with said sub-field, said method comprising at east a priming period for putting the cells in homogeneous states, with a position determined using the following steps: determination of a sustain threshold value D for a given addressing speed and panel technology, calculation of the number of sustain pulses in each sub-field n, n being such that 1≦n≦N, and for at least one sub-field n with n ≦N−1 and for which the number of sustain pulses is above or equal to D, addition of a priming period the beginning of the sub-field n+1.
