  • Ultra-short throw projector with transmissive liquid crystal display
    Patent number: 11099469
    Abstract: Devices, systems, and methods are provided for an ultra-short throw projector. The projector may include an illuminator having an ellipsoidal reflector, a light emitting diode (LED) positioned inside of the ellipsoidal reflector, and a Fresnel lens positioned inside of the ellipsoidal reflector. The projector may include a circular transmissive liquid crystal display (LCD) and a three-element plastic projection lens positioned outside of the ellipsoidal reflector, wherein the circular transmissive LCD is positioned between the ellipsoidal reflector and the three-element plastic projection lens, wherein the ellipsoidal reflector reflects light emitted by the LED, wherein the Fresnel lens refracts light emitted by the LED, and wherein the three-element plastic projection lens projects the reflected light and the refracted light.
