Abstract
In one embodiment, a color projection system includes a lamp; at least one prism configured to diffract light from the lamp into a diffracted beam; and an LC microdisplay panel or MEMS panel configured to receive the diffracted beam from the at least one prism, wherein by moving the at least one prism with respect to the light from the lamp, the diffracted beam received by the LC microdisplay or MEMS panel sequentially comprises a diffracted red beam, a diffracted blue beam, and a diffracted green beam, the LC microdisplay panel or MEMS panel being configured to sequentially modulate the diffracted red beam into a red sub-frame of an image, the diffracted green beam into a green sub-frame of the image, and the diffracted blue beam into a blue sub-frame of the image.
Claims16
A color projection system, comprising:
- a lamp;
- at least one prism configured to diffract light from the lamp into a diffracted beam;
- an LC microdisplay panel configured to receive the diffracted beam from the at least one prism;
- and means for moving the at least one prism with respect to the light from the lamp, such that the diffracted beam received by the LC microdisplay sequentially comprises a diffracted red beam, a diffracted blue beam, and a diffracted green beam, the LC microdisplay panel being configured to sequentially modulate the diffracted red beam into a red sub-frame of an image, the diffracted green beam into a green sub-frame of the image, and the diffracted blue beam into a blue sub-frame of the image.
A color projection system, comprising:
- a lamp;
- at least one prism configured to diffract light from the lamp into a diffracted beam;
- a digital light processor (DLP) configured to receive the diffracted beam from the at least one prism;
- and means for moving the at least one prism with respect to the light from the lamp such that the diffracted beam received by the DLP sequentially comprises a diffracted red beam, a diffracted blue beam, and a diffracted green beam, the DLP being configured to sequentially modulate the diffracted red beam into a red sub-frame of an image, the diffracted green beam into a green sub-frame of the image, and the diffracted blue beam into a blue sub-frame of the image.
A method of color projection comprising:
- providing a light beam incident on an at least one prism;
- moving the at least one prism with respect to the incident light beam, wherein the movement of the at least one prism is such that a diffracted light beam from the at least one prism sequentially comprises a diffracted red beam, a diffracted green beam, and a diffracted blue beam;
- sequentially modulating the diffracted red beam from the at least one prism to form a red sub-frame of an image;
- sequentially modulating the diffracted green beam from the at least one prism to form a green sub-frame of the image;
- and
- sequentially modulating the diffracted blue beam from the at least one prism to form a blue sub-frame of the image.
