<p>A stacked display panel construction (10) produces multishades of a single color, or a plurality of multiple colors (400, 500, 600). The system includes a nematic display panel (24) which, in one of its states, functions as a waveguide to rotate linearly polarized light from a colored polarizer (23), to produce noncolored light (NC1) from an output polarizer (25). In its other state, the display panel (24) twists the linearly polarized light to emit therefrom predominantly linearly polarized light for enabling the output polarizer (25) to emit colored light (R2). The method of making the construction includes adjusting the angle of rotation in the waveguide state of the panel (24), until only noncolored light (NC1) is emitted from the output polarizer (25). A display panel construction (800) includes three substantially identical nematic liquid crystal panels (824, 826, 828), associated electronic drive units (844, 845, 846) and associated polarizers (823, 825, 827, 829) for producing multiple colors.</p> |
