An optical light engine ( 100 ) includes one or more light-emitting diode (LED) panels ( 101, 102, 103 ) that are combined into a common path and directly imaged onto panel device to provide a source of light to a microdisplay panel ( 109 ). Preferably, the LED panel ( 101, 102, 103 ) is shaped such that the aspect ratio of light propagating the LED panel is substantially equal to the light received at the microdisplay panel ( 109 ). 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.
