Abstract

FIELD: automation and computer engineering. SUBSTANCE: device has screen unit, display processor, unit for output of information to cathode-ray tube, unit for information input and optical system. Screen unit of cathode-ray tube and optical system are designed as fiber-optical plate with light guides which ends are shaped as axial cones, which chambers are filled with material which refraction index is less than refraction index of material from light guide central fiber. Inner surface of fiber-optical plate is covered with alternating cathode- luminophore strips and signal plate strips, which are located in perpendicular to screen lines. cathode-luminophore strips are covered with metal coating. Signal plate strips are covered with photo conducting layer. Index wires are located between alternating strips. EFFECT: increased functional capabilities.
