TV PROJECTOR Russian patent published in 1997 - IPC

FIELD: optics. SUBSTANCE: TV projector includes three sources 10 of reference voltages each placed between transparent current conductive layer 3 and grounding electrodes 8 of proper intermediate medium of relief recording of line 1, three sources 12 of bias voltages each connected with one lead to like leads of group of sources of signal voltages connected with other ends to controlling electrodes 6 of one of intermediate media of relief recording of line 1 and with other end to grounding electrodes 8. Three outputs of synchronization device 28 are connected to three light sources 13 and one - to electric motor 25. Each intermediate medium of relief recording of line 1 has dielectric layer 7 located between controlling electrodes 6 and second backing 9. Light sources 13 are pulse ones. Repetition frequency of light pulses is equal to frequency of image lines. EFFECT: improved functional reliability of TV projector. 5 dwg
