Abstract
An image display device incorporating a specialized phase expansion circuit, a rotation circuit, a sampling device and unique controlling circuitry. The phase expansion circuit includes a plurality of trail buffers or sample holder circuits for receiving a serially applied train of pixel image signals, expanding or extending the assertion cycle time and generating a corresponding plurality of expanded image signal trains in parallel. Preferably, one combination of expanded pixel image signals corresponding to specific position of pixels arranged in matrix in one train is different from another combination of expanded pixel image signals. The rotational circuit includes a plurality of selecting circuits for receiving the manifold trains of expanded pixel image signals generated by the phase expansion circuit. Each selecting circuit preferably selects one of these trains of expanded pixel image signals and generates a corresponding second train of expanded pixel image signals in parallel according to variable combinations specified by the control circuit. The sampling device receives these second trains of expanded pixel image signals, reconstructs and generates image signal for driv…
