DEVICE PRESENTING IMAGE ON SCREEN OF LIGHT-VALVE PANEL Russian patent published in 1998 - IPC

FIELD: industrial and broadcast television, displays of television and functional type. SUBSTANCE: luminous flux is fed to input of connector and further on to inputs of waveguide channels made in lithium niobate via fibre-optical channel. Each waveguide channel presents electrooptical system using electrooptical effect in lithium niobate, that is emergence of optical anisotropy in transparent isotropic dielectric placed into external electric field. With supply of controlling voltage to buses voltage is fed to controlling electrodes which leads to execution of conditions of total internal reflection in waveguide channel and luminous flux with brightness determined by applied voltage or by dependence on time of switching on of waveguide channel is obtained across output of channel. By control over all waveguide channels one represents required image. EFFECT: expanded application field and increased efficiency of device. 2 cl, 7 dwg
