Patent number: 9568816Abstract: A projector system with a single imaging array has a low-etendue light source. The projector system includes a first optical path from the low-etendue light source to a plurality of optical conversion media having a plurality of emission wavelengths to provide display light with wavelengths longer than blue light. The projector system includes a second optical path from the optical conversion media to the imaging array. The projector system has a means of moving an excitation location on the optical conversion media in the first optical path. The projector system may include a blue LED, a diffuser region, or an optical conversion medium with a blue emission wavelength to provide blue display light. Light from the low-etendue light source is prevented from directly impinging on the imaging array.Type: GrantFiled: November 17, 2014Date of Patent: February 14, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: John Marshall Ferri, Sajjad Ali Khan, Michael Terry Davis, Vikrant R.
