Abstract

A portable phone (10) includes a handset (12) and an image projection system (44) configured to form a visual image (46) of data, such as caller waiting ID data, on a viewing surface (48) viewable by a user (14) during a two way conversation. The handset (12) also includes a speaker (26), a microphone (28), conventional phone circuitry (38) and a keyboard (32). The image projection system (44) is configured to receive signals from the phone circuitry (38), to generate a pattern (46") representative of the data, to process the pattern (46") into a mirror image (461) of the visual image (46), and to project the mirror image (461) from a bottom end surface (20) of the handset (12). The image projection system (44) includes an electro optic system (45) for generating the pattern, and an optics system (66) for projecting the mirror image (46') onto the viewing surface (48 ).

Description

technical field [0001] The present invention relates to portable communication devices, and more particularly to portable telephones, such as radiotelephones and cellular telephones. Background technique [0002] In the prior art, portable phones are widely used to communicate and transfer information between users. Cellular telephones include wireless telephones that receive signals from user-controlled base stations over relatively short ranges, typically on frequencies of 900MHz, 2.4Ghz or 5.8GHz. Cellular phones also include cellular phones for greater distances, which typically receive signals from telecommunication networks using various platforms such as ANALOG, CDMA (Code Division Multiple Access), TDMA ( TimeDivision Multiple Access, Time Division Multiple Access) and GSM (Global System for Mobilecommunication, Global System for Mobile Communications). Cellular phones also include satellite phones, wherein the cellular phone transmits directly to or from communica...
