A flat-panel modulator includes a plurality of separately modulatable elements or pixels in which the modulating elements on the panel are arranged, notionally or physically, into patches or blocks (shown schematically as 53a, b, c) of individual modulating elements such that space between each patch exists which has no modulating elements. Addressing lines can be located in the space between the blocks, decreasing resistivity. Also the optical resolution of the magnifying optics is much better than if the entire panel were imaged as a whole. Furthermore a seamless image can be built up using suitable optics (51) between the modulator blocks and a screen (52), at least some of the blocks being magnified.
A flat-panel modulator including a plurality of separately modulatable elements or pixels, in which the modulating elements are arranged into patches or blocks (12, 53) of individual modulating elements such that space (13) between each patch exists which has no modulating elements.
A modulator according to any preceding claim and being constructed on a single transparent substrate.
A modulator according to any preceding claim, in which pixels are made from a transparent conducting material and addressing lines are made from or include a metallic or non-transparent conducting material of lower resistivity.
A modulator according to any preceding claim, in which the patch (141) size is uniform across the modulator.
A flat-panel modulator including a plurality of separately modulatable elements or pixels and a driver for addressing them, in which the driver addresses a plurality of pixels in parallel in such a way that the effect is of a single larger pixel, and a plurality of such larger pixels are addressed on the entire modulator.
A flat-panel modulator including a plurality of separately modulatable elements or pixels and a driver for addressing them, in which the driver addresses pixels in patches or blocks of individual pixels in such a way that the pixels between each patch are not modulated.
A display according to any of claims 15 to 25, in which the means for producing activation light is un-collimated but vignetting between and/or within optical arrangements is employed to prevent image degradation.
