FIELD: radio communications for color television sets in analog and digital television systems. ^ SUBSTANCE: novelty is that digital television set incorporating radio channel unit, line sweep unit, frame sweep unit, color unit, first and second piezoelectric deflectors each carrying reflector at end, brightness modulation unit, flat screen, pulse generator, switch, and three identical color control channels each incorporating analog-to-digital converter and pulse amplifier unit is provided in addition with two amplifiers, four reference-voltage sources, frame sweep shaper, and optical projection system; in addition each color control channel is provided with code storage, brightness modulation unit has ten channels, each channel incorporating radiator of three main colors, lens, and focusing cone of light guide. Frame sweep occurs on flat screen simultaneously with ten lines repeated ten times. Number of active lines per frame is 578 with 720 readings in each; each frame has 416160 resolving picture dots. ^ EFFECT: enhanced averaged brightness, picture brightness being higher by order of magnitude. ^ 1 cl, 10 dwg, 2 tbl |
