Abstract
A large screen image display device has a rear wall on which a plurality of striped vertical addressing electrodes are formed, a front wall to which a conductor and phosphor are laminated, and mutually spaced side walls to form an evacuated enclosure wherein the conductor and the addressing electrodes confront each other. Linear thermal cathodes are disposed in rows orthogonal to the addressing electrodes for emitting thermal-electrons. At least one modulation electrode is located between the thermal cathodes and addressing electrodes in parallel to the respective thermal cathode. Horizontal focusing deflection electrodes are arranged opposite to and in parallel to both sides of the thermal cathodes. A control circuit supplies control signals to the above mentioned electrodes for operating the device.
