Method for controlling a display device such as a plasma monitor whereby an improved coding method is used for secondary fields that results in reduced pseudo contour intensity

摘要

Method for controlling a display device in which, for example, in an input signal with 256 graduations, first secondary fields (SF1, SF2, SF7, SF8) operate with a gray scale of 15, while other secondary fields (SF3, SF9) operate with a gray scale of 16. The difference in weighting is 3 both lower and higher values. The invention also relates to a corresponding command circuit.
