Abstract
Disclosed is a method for the control of display screens that can be applied to internal memory type screens, notably plasma display panels for which it increases the dynamic range of the adjusting of the luminosity. This method consists in controlling the cells (C1 to C16) of the screen by means of addressing commands, each one of which comprises a selective command and a semi-selective command. According to one characteristic, for the addressing of one and the same line (L1 to L4) of cells (C1 to C16), the method consists in separating the selective command (CI) from the semi-selective command (CE) by an adjustable interval of time (PL1 to PL4).
