Abstract

A projection system can include a housing. A controller can receive a video signal and, in response to the video signal, produce a light-emitting diode (LED) array-controlling signal and a modulation panel-controlling signal. An LED array disposed in the housing can include LEDs that are configured to produce LED light having corresponding time-varying intensities in response to the LED array-controlling signal. A modulation panel disposed in the housing can have a plurality of pixels that are configured to modulate corresponding portions of the LED light in response to the modulation panel-controlling signal to form intensity-modulated light. A lens disposed in or on the housing can project the intensity-modulated light out of the housing to form a video image that corresponds to the video signal. The video image can be located away from the housing.
