DEVICE FOR TESTING AND REGULATION OF ELECTRONIC DISPLAY DEVICES Russian patent published in 2000 - IPC

FIELD: tuning units for cathode-ray tubes (CRT). SUBSTANCE: device has video structure generator, which is connected to cathode-ray tube for generation of video image to be displayed. Goal of invention is achieved by introduced multiple detectors with independent field of vision. They contain multiple color CCD-camera heads, which are mounted on testing board and are designed for reading and displaying image signals, which correspond to separate objects on said image of video structures on CRT unit. Each optical detector has color CCD-camera head, controllers of CCD-camera heads, each of which is equipped with digital multiplexer for directing digital information from CCD- camera heads to video signal channel processor. In addition device has computer, which has said processor for digital information processing, and graphical user interface for supporting operations of operator tuning CRT unit according to procedure for CRT unit testing and regulation. EFFECT: increased speed, simplified design and increased precision of testing. 13 cl, 13 dwg
