Abstract (en)
[origin: US4672272A] A flat picture reproducing device includes a vaccum-tight envelope containing an electrode matrix formed of row conductors and column conductors disposed in front of the row conductors and having holes at respective crossings thereof, the matrix dividing the interior of the envelope into a rear and a forward chamber; an areal electron source in the rear chamber; elongated vertical deflection electrodes disposed in the forward chamber in a plane parallel to the plane of the matrix and, respectively, running between rows of the holes parallel to the row conductors, a respective single one of the vertical deflection electrodes being disposed between respective hole rows of adjacent pairs of the hole rows; the envelope having a wall on the forward side thereof coated with a layer of material luminescent when excited by electrons; an addressing circuit for scanning the row conductors sequentially to construct a picture line-by-line, each of the row conductors remaining addressed for at least one picture-row period, the addressing circuit providing the respective column conductors, during each picture-row period, with appertaining picture-row information signals so that the electrons delivered by the electron source can pass selectively through the holes of the electrode matrix; the vertical deflection electrodes having different potentials applicable thereto in synchronism with the picture frequency in a manner that the electrons entering the forward chamber are deflected, respectively, upwardly or downwardly.
