Abstract
A method of adjusting the colors of a polychrome plasma panel is provided, including a plurality of elementary image points, each point being formed by several zones covered with luminophores of different colors, each of these zones corresponding to the intersection of electrodes for applying control signals and more particularly a holding signal to each zone during operation, which method consists in applying to the different zones of each elementary image point a respective holding signal at an adjustable frequency, identical for all the luminophores of the same type of all the image points of the panel, and the colors of the panel are adjusted by adjusting the frequency of the different holding signals used.
