Abstract
A visual display system, composed of an array of light emitting devices, forming an image source, a phase spatial light modulator scanner, driver/control circuitry and an optical magnification system. The display system being enclosed within a housing, thereby forming an optical magnifier. The phase spatial light modulator scanner is operative in either a transmissive mode or a reflective mode. In operation, an external stimulus, such as a voltage, is applied to the scanner, thereby changing the phase of light emitted therethrough. The scanning action enhances display resolution of the generated resultant image without an increase in the number of pixels of the image source. The phase spatial light modulator scanner operates by scanning sub-pixels, pixel groups, and/or sub-arrays of the image source.
