Abstract

The present invention is a portable electronic video display. The display is configured to be worn on the arm or wrist of a user, or stored in a pocket or backpack. The display is raised to eye level and the user looks through an eyepiece to view the video display. Control buttons are located on the display for generating point and click type commands. The display is meant to be used remotely from a computer. The computer could be worn or carried by the person or simply be free standing, some distance away. The computer is configured to convert video signal into a serial data stream and then transmit that stream via an RF signal. The display then receives that signal and converts it back into a video signal, displaying it on a miniature electronic video display. That image is them magnified through various optics to present a final image to the user. The point and click commands are separately transmitted back to the computer, where they are received and acted upon.

Claims

1. A portable electronic video display comprising a housings, a display mounted in said housing, an optics assembly coupled to said display wherein said optics assembly includes a field flattening lens, a color shutter, a reflective folding prism and a doublet lens mounted in optical alignment with the display, and an RF receiver coupled to said display for receiving a signal from a source and inputting the signal to said display.

2. A portable electronic video display according to claim 1, further including a data input control mounted to said housing and coupled to a transmitter for sending control signals to a stand alone computer.

3. A portable electronic video display according to claim 1, wherein said display comprises an electroluminescent color sequential display.

4. A portable electronic video display according to claim 3, further including an LCD color shutter coupled to said display.

5. A portable electronic video display according to claim 1, wherein the housing comprises an enclosed chamber and a viewing opening, wherein the viewing opening comprises an eyepiece configured such that an eye region of the operator may be placed proximate the eyepiece, and further wherein the portable electronic video display comprises a power switch coupled to the eyepiece so that power is only delivered to the display when the power switch is engaged.

6. A portable electronic video display according to claim 1, wherein the source further includes a stand alone computer remotely linked to the portable electronic video display.

7. A portable electronic video display according to claim 6, further having a VGA connector of the computer connected to a RF data transmitter, the transmitter including an analog to digital converter for converting an analog video signal generated by the computer into a digital signal transmittable by the transmitter.

8. A portable electronic video display according to claim 7, including an antenna coupled to the receiver, wherein the digital signal sent by the transmitter is received by the receiver through the antenna and converted into an analog signal and sent to the display.

9. A portable electronic video display for use in conjunction with a computing device, comprising:

a housing configured to be worn on a part of the human body;

a receiver mounted in said housing;

a color sequential video display coupled to said receiver for displaying a video image of a signal received by the receiver;

a LCD color subtractive shutter optically aligned with the video display;

an optics assembly coupled to the display for allowing an operator to view the image generated by the display wherein the optics assembly includes a field flattening lens interposed between the display and the LCD shutter, a reflective folding prism, and a doublet lens optically aligned with the display for providing a viewable image to an operator; and

a data input control mounted to the housing and including a transmitter for transmitting control signals to a remote computer.

10. A portable electronic video display according to claim 9, further including a stand alone computer remotely linked to the portable electronic video display.

11. A portable electronic video display according to claim 10, further having a VGA connector of the computer connected to a RF data transmitter, the transmitter including an analog to digital converter for converting an analog video signal generated by the computer into a digital signal transmittable by the transmitter.

12. A portable electronic video display according to claim 11, including an antenna coupled to the receiver, wherein the digital signal sent by the transmitter is received by the receiver through the antenna and converted into an analog signal and sent to the display.

13. A computer system comprising:

a computer having a video output coupled to an analog to digital converter, a transmitter coupled to the analog to digital converter for sending a video signal, and a receiver for receiving control signals from a remote source;

a display having a housing configured to be worn on a part of the human body;

a receiver mounted in said housing for receiving video signals from the transmitter;

a video display coupled to said receiver for displaying a video image of a signal received by the receiver;

an optics assembly coupled to the display for allowing an operator to view the image generated by the display, wherein the optics assembly includes a field flattening lens, a reflective folding prism, and a doublet lens optically aligned with the display for providing a viewable image to an operator; and

a data input control mounted to the housing and including a transmitter for transmitting control signals to the computer.
