Abstract

A hand-held terminal such as a smart phone comprised of 2 components—a front face and a back face. A touch screen display is embedded in the front face entirely occupying said front face; said front face to have no visible components in its top and bottom strips including the home button, speakers, microphone, sensors, and front camera (“Components”). The back face contains the relocated Components as well as substantially all the other smart phone elements. The intent is to achieve a true full panel display that covers the entire face of the device. Disclosed are embodiments to make the Components fully accessible and functional, including an integrated back panel slider mechanism, a built-in spring loaded module, and an integrated flip component. The front panel display space now includes the top and bottom strip areas and becomes a true full screen display covering the entire face of the device.

5. The method of claim 1, further comprising:

embedding a slider mechanism between the inward face of the front panel and the inward face of the back panel of the mobile communication device, such that the back panel can alternately be slid up against the front panel to expose components on the top strip area or slid down against the front panel to expose components on the bottom strip area.

6. The method of claim 5, further comprising:

providing an electronic relay electrically coupled to the back panel'"'"'s inner face and to the slider mechanism; and

providing a transmitter electrically coupled to the electronic relay; and

providing an electronic processor electrically coupled to the CPU configured to;

receive a signal from the transmitter whenever the electronic relay changes state between open and closed as a result of a sliding movement of the back panel; and

send a signal to the CPU to change the mode between sleep and active of at least one of the components located within the top or bottom strips of the back panel'"'"'s inward face.

7. A method for manufacturing a mobile communications device with a display area covering substantially an entire full face of the device, comprising:

providing a device case of hand-holdable size, said device case comprising a front face and a back face;

embedding in the front face of said device case a touch screen display panel entirely occupying said front face except for rims surrounding said display panel;

said touch screen display panel having no visible components therein;

providing, coupled with the device case, a movable camera module comprising a camera and one or more additional components comprising a flash, wherein the movable camera module is slidable or hingeable relative to the device case, wherein the camera and the flash of the movable camera module are selectively presentable to a user on the front of the mobile communication device while the touch screen display panel is facing the user, and

providing a processor configured to;

receive a signal when the movable camera module is moved such that the camera and flash are presented to the user; and

change, based at least in part on the signal, a mode for the camera between sleep and active mode or between a front camera mode and a rear camera mode, wherein the mode for the camera changes depending on the position or orientation of the movable camera module.

8. The method of claim 7, further comprising:

wherein providing the movable camera module coupled to the device case comprises embedding a spring-loaded housing module in the device case, wherein the built-in spring loaded housing module comprises a housing at least partially hidden within the top frame of the back panel such that said housing springs up and sits on the top face of the back panel whenever the user releases said housing.
