Superimposed Flat Panel Technique

While A.C. plasma display panels have been developed and are commercially available, two desirable aspects of the display are higher line resolution and multi-color capability. A system for providing or enhancing either or both features is constructed as follows.

Referring to the drawing, a direct view panel 3 and a reflected view panel 5 are imaged on a half-silvered mirror 7. Panels 3 and 5 are conventional A.C. panels, the reflected or reverse image on panel 5 being electronically reversed through conventional means to provide the viewer with a true image. The two panel images are thus superimposed to provide a single image on the half silver mirror. By adjusting the relative positions of the images, the line resolution can be increased up to a factor of two on one or both axes.

To provide color capability, red, yellow and orange, for example, the direct view panel can have an associated red filter 9, while reflected view panel 5 can have a yellow filter 11. Thus display cells of red, yellow or both can be simultaneously selected to provide a three color capability. Individual driver currents would not be required for each panel, since both panels could be converted to the same drivers in one dimension.
