Abstract (en)

[origin: EP0747875A1] The screen has an anode (5) with luminophores (7r,7g,7b) on at least two sets of conductive strips (9) which are bombarded with electrons from micropoints (2) of the cathode (1). The control introduces phases of regeneration during which the anode is at low potential while the corresponding cathode is biased in an emissive condition. The regenerative phases are interspersed among the display phases within a repetitive cycle whereby the red, green and blue subframe periods follow one another with a regenerative period between each blue and the next red.
