Abstract:
1. A method for generating a presentation image, comprising the steps of: operating a microdisplay panel device to generate a sequence of images; operating a plurality of light-emitting diodes in correspondence with the operation of the microdisplay panel device, the plurality of light-emitting diodes each being operable to emit light having one of a plurality of colors; collimating light from the plurality of light-emitting diodes; combining the collimated light from the plurality of light-emitting diodes with a combiner into a common path; condensing light from the combiner for presentation to the microdisplay panel; for each of the plurality of light-emitting diodes, directly imaging light from each light-emitting diode onto the microdisplay panel device, such that an image of the light-emitting diode is formed on the microdisplay panel device, wherein such image is first processed in order by the steps of collimating, combining and condensing prior to being formed on the microdisplay device; and projecting the sequence of images generated at the microdisplay panel device.
