Abstract
An optical light engine () includes one or more light-emitting diode (LED) panels () that are combined into a common path and directly imaged onto panel device to provide a source of light to a microdisplay panel (). Preferably, the LED panel () is shaped such that the aspect ratio of light propagating the LED panel is substantially equal to the light received at the microdisplay panel (). An aspect ratio of 4:3 or 16:9 is typically selected in view of the sizes of the LED panels used in the light engine.
