ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to wireless telephones, and has particular relation to wireless telephones which may be used in multiple modes, such as audio, video, Internet, and the like.
It is expected of a wireless telephone only that it will have a keypad, a microphone, and an earpiece or other speaker. In this respect, it is like a wireline telephone. If video or Internet capabilities are to be added on to a wireline telephone, the add-on nature of these capabilities is apparent. No one expects a conventional wireline telephone to have video or Internet capabilities. These capabilities are instead provided by a personal computer (PC). The only significant connection between the PC and the telephone is that they share the same telephone line.
Miniaturization has proceeded more quickly in wireless telephones than in wireline telephones because light weight and low power consumption are so much more important. It has thus become possible, at least in semi-portable telephones, for a wireless telephone to have video and Internet capabilities. What has not yet been possible is for these capabilities to be designed in a user-friendly configuration.
SUMMARY OF THE INVENTION
This invention overcomes these difficulties by providing a video monitor which is thin enough for a touch-screen to slide partially beneath it, with enough room for a touch-screen-cover to slide between them. The touch-screen-cover, when not slid between the touch-screen and the monitor, covers the part of the touch-screen which the monitor does not cover. When the touch-screen-cover is slid between the touch-screen and the monitor, it does two things. First, it exposes the parts of the touch-screen which are not covered by the monitor. Second, it allows the touch-screen to be slid completely out from underneath the monitor, thereby exposing all of the touch-screen. Thus, the touch-screen may be completely covered, partially covered, or completely uncovered. Each covering configuration is suited for a different set of wireless telephone capabilities.
