radio communication equipment, applicable as a color television receiver in analog and digital television systems. SUBSTANCE: the digital TV set has a radio channel unit, line scanning unit, frame scanning unit, chromaticity unit, the first and second piezodeflectors with reflectors on the end, lusterless screen, three similar chromaticity beam control channels, each comprising series-connected analog-to-digital converters and the first of pulse amplifiers, pulse generator and a key, introduced is an intensity modulation unit made as a component of the first and second radiators, each having the respective number of light-emitting diodes of the respective colors, and an optical system, introduced in each chromacity control unit are a delay elements unit and the second unit of pulse amplifiers, the outputs of the units of pulse amplifiers of the three channel are connected to the respective inputs of the intensity modulation unit. The beam from the first radiator performs scanning of the raster line, the beam from the second radiator repeats it once again, which increases the average screen brightness by two times. EFFECT: enhanced average brightness of image on the screen due to enhanced brightness of the resolving picture element and repeated sweep of each line. 2 dwg, 1 tbl
