Abstract
A drive system which makes it possible to drive a matrix of picture elements, each including a cathode made of a material with low electron affinity. Each of crossover-point circuits include a switching device associated with a cathode of a picture element and makes it possible, with the aid of memory circuits, to connect the cathode to a current source during a time necessary for the driving of all the rows of the matrix and to regulate the current conduction of the corresponding picture element. Such a drive system may find particular application to electron guns and display screens.
