摘要:
Colour image display device of the liquid-crystal type, particularly for recreational machines. The device consists of a stack of simple liquid-crystal display elements (LCD elements) according to twisted nematic technology, as many LCD elements being stacked as colours, white excepted, are desired; interposed polarising filters of various shades with predetermined shape and predetermined direction, constituting a compact assembly with the LCD elements; each being activators of alternating current and associated with each one of the LCD elements, mosaics of points, lines and complex shapes being arranged in the elements, the various images being achieved through sequences of "activated" /"non-activated" states of the elements; and a system of transflection illumination.
