Abstract
A multiplex control active matrix display screen including a first transparent substrate supporting an array of electrodes controlled by an array of transistors. Each transistor has two control gates. The second gates are interconnected along an addressing row or column. The rows and columns are interconnected in groups of N. The transistors of a column or row are then controlled by multiplexed three control signals.
