Control process for luminosity of plasma display panel

摘要

The process involves controlling the global luminosity of at least part of a matrix screen. Each line of the screen part is processed several times in a non-periodic manner. Each process consists of a semi-selective operation (E) followed by a selective operation (I). A delay is provided between the selective operation (I) and the semi-selective operation (E). The delay is proportional to a weighting factor which is adjustable as a function of the required global luminosity, and a function of the time interval separating the start of the processing and the start of the following processing.
