Abstract
A portable docking station system for a liquid crystal display assembly using an arc lamp and a compact optical assembly to project video or data onto a viewing screen. The system includes a color sequential operating system to convert a monochrome liquid crystal display into a high-speed, high resolution, high brightness, color projection display. Video generating and receiving systems as well as an audio system can be incorporated into the docking station to provide a portable presentation system.
Claims36
A docking station for a liquid crystal display assembly comprising:
- a housing for the docking station, the housing having an opening through which a liquid crystal display panel can be inserted;
- a support element on the housing, the support element being capable of holding the display assembly relative to the housing;
- an image storage device mounted within the housing for providing a selectable image from storage;
- an electrical coupler between the housing and the display assembly for electrically connecting the image to the display panel for forming the selected image;
- an arc lamp light source mounted within the housing that emits light directed through a liquid crystal display panel inserted through the opening;
- a projection optical system mounted within the housing and which is optically coupled to the display panel when the display panel is inserted in the opening, the projection optical system projecting the selected image formed on the display panel onto an exterior viewing surface;
- and
- a mirror positioned within the housing, the mirror reflecting light from the light source along a first optical path onto a second optical path extending through the projection optical system.
A docking station for a liquid crystal display assembly comprising:
- a housing for the docking station, the housing having an opening through which a liquid crystal display can be inserted;
- a light source mounted within the housing that emits light directed through a liquid crystal display panel inserted through the opening;
- a projection optical system mounted within the housing and which is optically coupled to the display panel when the display panel is inserted in the opening, the projection optical system projecting an image formed on the display panel onto an exterior viewing surface;
- and
- a sequential light system mounted within the housing such that light of different frequencies are sequentially directed through the projection optical system.
A method of docking a liquid crystal display assembly comprising:
- providing a housing for a docking station, the housing having an opening through which a liquid crystal display panel can be inserted, an arc lamp light source mounted within the housing, a video storage device within the housing for providing selectable video signals from storage and a projection optical system mounted within the housing;
- mounting the display assembly onto a surface of the housing such that the display panel is inserted through the opening and into the housing to optically couple the light source to the liquid crystal display;
- electrically coupling the video circuit to the display panel;
- forming an image on the display panel using signals from the video storage device;
- and
- projecting the formed image through the optical system onto an exterior viewing surface.
The method of clam 24 further comprising providing a wireless receiver within the housing to receive video or television signals from a transmitter.
A docking station for a liquid crystal display assembly comprising:
- a housing for the docking station, the housing having an opening through which a liquid crystal display panel can be inserted and a volume of less than about 220 cubic inches;
- a support element on the housing, the support element being capable of holding the display assembly relative to the housing;
- an arc lamp light source mounted within the housing that emits light directed through a liquid crystal display panel inserted through the opening;
- a projection optical system mounted within the housing and which is optically coupled to the display panel when the display panel is inserted in the opening, the projection optical system projecting an image formed on the display panel onto an exterior viewing surface;
- and
- a mirror positioned within the housing, the mirror reflecting light from the source along a first optical path onto a second optical path extending through projection optical system.
