Abstract

The invention is a projection system for mobile phones, personal communications devices, mobile computers, wearable computers, personal digital assistants (PDA'"'"'s), desktop phones, and other devices which contain integral display screens, herein after designated as communication devices and portable computing devices. The projector is either integral to the device itself, integral to a charger or stand for the device, or inserts into the device via a card slot. The projector expands the display capability by allowing users to project images which would otherwise be displayed on screens integral to such devices onto a surface with larger dimensions for easier viewability.

Claims

1. ) A digital projection system for communication devices and portable computing devices which comprises:

A device which is selected from the group consisting of communication devices and portable computing devices;

A display screen which is integral to said device;

A video projector for projecting an image derived from said device wherein said video projector is not an external stand-alone video projector;

Circuitry for relaying output which would be displayed on said display screen to said video projector.

2. ) The system of claim 1 wherein said projector in built integral to the housing of said device.

3. ) The system of claim 1 wherein said projector is a back lit video projector.

4. ) The system of claim 1 wherein said projector is a monochrome projector.

5. ) The system of claim 1 wherein said projector is a color projector.

6. ) The system of claim 1 wherein said projector is built integral to the battery charger or desktop holder of said device.

7. ) The system of claim 1 wherein said projector is built into a card which slides into a card slot on said device.

8. ) The system of claim 1 wherein said projector projects images and text which are larger in physical size than if displayed on the display screen which is integral to said device.

9. ) The system of claim 1 wherein said projector projects images and text which are at least as high in resolution and which contain at least the same amount of simultaneous characters as the display screen which is integral to said device.

10. ) The system of claim 1 wherein said projector projects data and images from a memory contained in said device.

11. ) The system of claim 10 wherein said data and images include an operating system of said devices, information stored in the memory of said devices, text images, graphic images and motion videos.

12. ) The system of claim 1 wherein said projector is operable to rotate about an axis to afford selective placement of the projected data and images on the surface to which it is being projected on.

13. ) The system of claim 12 wherein said projector recesses or flips back in order to protect its lens when not in use.

15. ) The apparatus of claim 14 wherein said projector is integral to the enclosure of said device.

16. ) The apparatus of claim 14 wherein said projector is integral to a charger or holster for said device.

17. ) The apparatus of claim 14 wherein said projector is operable to display text, graphics, an operating system running on said device, video images and motion video.

18. ) The apparatus of claim 14 wherein said projected images and text are larger in physical size and at contain at least the same number of simultaneous characters as if they were displayed on the display integral to said device.

14. ) An apparatus for projecting display information from a communication device or portable computing device, the apparatus comprising:

A device selected from the group consisting of communication devices and portable computing devices;

A display which is integral to said device.

A video projector;

A lens and light source which facilitates back lighting to project data and images from said device;

Circuitry for relaying said data and images which would be displayed on said display to said projector.

19. ) A method for projecting images from a communication device or a portable computing device, the method comprising the steps of:

Incorporating a video projector into a device selected from the group consisting of communication devices, portable computing devices, charging stations for such devices, and cards which insert into a slot in such devices, wherein said device possesses an integral display screen, and further wherein said incorporating includes integrating the projector into said device or into an attachment or component which mates with said device;

Projecting images from said device using said projector, wherein said images include operating system interface, text data, graphic data, video data, and motion video;

Projecting images in a format which is larger in physical dimensions and at least as large in the number of simultaneous characters then if like images where to be displayed on a screen integral to said devices.

20. ) An apparatus for projecting text and images from communication devices and portable computing devices, the apparatus comprising:

A device selected from the group consisting of communication devices and portable computing devices;

Display means integral to such a device;

A projection means for such a device operable to project text and images in a manner which is both physically larger and includes at least as many simultaneous characters than if displayed on such a device'"'"'s integral display means.

21. ) A video projection system for use with communication devices and portable computing devices, the system comprising:

A device selected from the group consisting of communication devices and portable computing devices;

A video projector;

Means for communicating output data which would be displayed on a display integral to said device to said projector;

Means for projecting data from said device by said projector;

Means for concealing or removing said projector when not in use.

22. ) The video projection system of claim 21 wherein said projector is integral to said device.

23. ) The video projection system of claim 21 wherein said projector is attached to a card which inserts to a card slot on said device when in use.

24. ) The video projection system of claim 21 wherein said projector is built into a stand, charger, or docking station for said device.

25. ) A method of video projection for use with communication and computing devices, the method comprising:

Providing one of a communication device and a portable computing device with a video projector,

wherein the step of providing is a chosen from the group consisting of building a projector integral to the said device, building a projector into a charging station for said device, and building a projector into a card which inserts into a card slot integral to said device;

Providing a data pathway from a memory in said device to said projector to facilitate transmission of data representative of video output;

Projecting said video output by said projector, said output originating from a memory in said device.
