PROCEDE DE COMMANDE D'UN ECRAN DE VISUALISATION D'IMAGE UTILISANT LE PRINCIPE DE LA MODULATION DE DUREE D'EMISSION DE LUMIERE, ET DISPOSITIF DE VISUALISATION METTANT EN OEUVRE LE PROCEDE

摘要

The plasma display control determines the activation time of each display cell in response to the level of luminance required from that cell. The sequence of activations of the cells is controlled by selection of control lines. Within each display sequence a sub-sequence is implemented , with variable ratio of activation and de-activation of each cell to produce illumination from the cell at levels between a set maximum and minimum.
