ABSTRACT:

FIELD OF THE INVENTION
The present invention pertains, generally, to portable communications transceivers and, more particularly, to visual displays with portable communications transceivers.
BACKGROUND OF THE INVENTION
Portable communications transceivers, such as cellular and cordless telephones, pagers and the like, are becoming increasingly popular. In many instances it is desirable to provide a visual display on the transceiver to supply the operator with a visual message or graphical image. The problem is that visual displays require relatively high electrical power and require a great amount of area to be sufficiently large to produce a useful display.
In the prior art, for example, it is common to provide visual displays utilizing liquid crystal displays, directly viewed light emitting diodes, etc. These produce very large and cumbersome displays that greatly increase the size of the transceiver and require relatively large amounts of power.
In one instance, the prior art includes a scanning mirror to produce a visual display but again this requires relatively large amounts of power and is very complicated and sensitive to shock. Also, the scanning mirror causes vibration in the unit that substantially reduces visual comfort and acceptability.
SUMMARY OF THE INVENTION
Briefly stated, a portable communications transceiver having a first hollow body, a second hollow body, a communications receiver, a transmitter, and a miniature virtual image display having a viewing aperture. The miniature virtual image display is contained in the second hollow body operably attached to the receiver and including image generation apparatus for providing a real image. A fixed optical system produces, from the real image a virtual image viewable through the viewing aperture.
It is an advantage of the present invention to provide a new and improved portable communications transceiver with miniature virtual image display.
It is a further advantage of the present invention to provide a new and improved portable communications transceiver with miniature virtual image display that substantially reduces the amount of power required.
It is a further advantage of the present invention to provide a new and improved portable communications transceiver with miniature virtual image display requiring substantially less space to provide a useful and easily viewable display.
It is a further advantage of the present invention to provide a new and improved portable communications transceiver with a miniature virtual image display to enable the operator to easily view a virtual image and simultaneously be able to carry on voice communication.
