ABSTRACT:
A method and apparatus for displaying the graphic and alphanumeric data of the type utilizing pixel matrix panels with an outside light source. The method comprises reflecting the outside light on a preselected colored surface, rotatably housed within each matrix pixel.
Every pixel comprises a cylindrical container (1) having a transparent non-flat cap (3) at one of bases, the other base being missing. The container (1) houses a radiation deflector (5) and a hollow cylinder (7) having two or more reflecting areas (10), differently colored, located on its lateral surface (9).
An external light radiation enters the container through the cap (3), is deflected by the deflector (5) and is reflected by one of the reflecting areas to be again deflected and directed to the outside.
The hollow cylinder (7) is operated by an electromagnetic control so as to alternatively present to the deflected radiation a preselected colored area.
