[Figure 12] FIG. 12 is a front view of the modular portable electronic device of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] Referring now to Figure 1, a front view of a portable electronic device 100 with a spring-loaded unfoldable display is shown in a folded state. In the illustrated embodiment, the portable electronic device is a "tri-fold, foldable" device that is provided with a flexible touch display of a known type. When the portable electronic device is unfolded, the display area increases by three times. The portable electronic device is configured so that the display folds outward like a scroll (rather than inward like a book).

[0016] Within the body of the portable electronic device, springs (101A, 101B) are provided, in some embodiments a single spring may be provided.

[0017] An end view of the portable electronic device of FIG. 1 is shown in FIG. 2. The body 201 is flanked on either side by an assembly including hinge mechanisms (203A, 203B) and screen extension members ("screen extensions," 205A, 205B). The screen extensions provide support for the folding and unfolding portions of the display. In the folded position shown, the screen extensions overlap the back of the body. A foldable display 207 is supported by the body on the front of the portable electronic device, wraps around the hinge members, overlaps the back of the body, and is supported by the overlapping screen extensions. In this configuration, the active viewing sides of the foldable display are the front-facing and rear-facing.

[0018] A front view of the portable electronic device of Figure 1 in an unfolded state is shown in Figure 3. Dashed lines are used to indicate the three-fold increase in display area, but the foldable display 207 is continuous and uninterrupted.

[0019] A rear view of the portable electronic device of Figure 1 in the unfolded state is shown in Figure 4. In the unfolded state, the assemblies 203A / 205A and 203B / 205B are arranged so that the screen extensions (205A, 205B) are extended outward in a plane defined by the front of the body 201, instead of overlapping at the back of the body. The hinge mechanisms (203A, 203B) are supported by rods and are spaced a distance from the body 201 to take up slack in the display that occurs during unfolding. During unfolding, the hinge mechanisms gradually move away from the sides of the body to assume the final position shown in Figure 4.

[0020] In one embodiment, the spring can be a two-way gas spring with damping and locking capabilities. In the locked state, the rod is held within the cylinder. When unlocked, the rod is forced outward with a damped movement. Unlocking the rod can occur with a light push, or "double push," on the rod. This type of spring is available, for example, from HXL Gas Spring Co., Ltd., Xiamen, Fujian Province, People's Republic of China.

[0021] In other embodiments, unlocking occurs electronically: an electric current is applied to an element within the cylinder that expands or contracts in such a way as to unlock.

[0022] In other embodiments, the spring may be a wound spring or other type of spring.

[0023] The portable electronic devices of Figures 1-5 may be "self-deploying" as described herein.

[0024] Referring to FIG. 6, according to one embodiment, the device is held in portrait orientation and face down (step 601). The user then double-pushes both sides of the device toward each other (step 603). The user then holds their hand flat, allowing the device to deploy (step 605). In response to the double-push, the gas spring rod is released, allowing the device to extend in a damped manner until fully deployed. The user then grasps the device and flips it forward for use (step 607).

[0025] Alternatively, "self-deployment" can be electronically controlled. Referring to FIG. 7, according to one embodiment, a user rotates the device into portrait orientation and face-down (step 701). This positioning of the device constitutes a movement gesture recognized by the device. The device recognizes the gesture and unlocks the spring (step 703). The user then holds their hand flat, allowing the device to deploy (step 705). In response to the unlocking, the gas spring rod is released, allowing the device to extend in a damped manner until fully deployed. The user then grasps the device and rotates it forward for use (step 707).

[0026] Referring to FIG. 8 , another embodiment of a portable electronic device 800 is shown. The device can be provided with a camera module 803. The camera module 803 can incorporate some or all of the cameras found in state-of-the-art smartphones. In particular, the camera module can incorporate the camera that may be rear-facing in state-of-the-art smartphones. Conversely, creating a front-facing camera avoids interference with the foldable display.

[0027] The device may be provided with springs 801A and 801B, similar to the device of Figure 1. The signal from the camera module 803 may be routed around spring 801A.

[0028] The camera module 803 may include a speaker, microphone, buttons, ports, etc. along its top surface as desired. The camera module 803 may also include an antenna.

[0029] In some cases, the same camera module 803 can be used to take forward-facing and rear-facing photos. If the camera is a variable-focus camera, the device can sense the orientation of the device (forward-facing or rear-facing) and adjust the focus accordingly.

[0030] Referring to Figure 9, to take a rear-facing photo, the user uses the touch display to select "camera" and then "rear-facing" (step 901). The user now rotates the phone so that the normally forward-facing camera module is rear-facing (step 903). The formerly rear-facing portion of the display is now forward-facing and activated for viewing and control (step 905). The user then takes the photo in the normal manner (step 907).

[0031] In some cases, a separate rear-facing camera module with more advanced capabilities may be provided so that the camera is covered when the display is folded. During display unfolding, the camera may be activated by default in preparation for taking pictures. Switching between portrait and landscape orientation may be accomplished by touch input or gesture without changing the device orientation.

[0032] Referring to FIG. 10, a rear exploded view of a modular portable electronic device is shown. One module 1001 can be a main body containing a main processor. Another module 1003 can be a folding screen module. The folding screen module can include a screen extension, hinge mechanism, and springs arranged largely as in the previous embodiment. The folding screen module can also include a camera module as described in connection with FIG. 9. The folding screen module can also include snap-fit ​​connectors 1005A and 1005B. The main body 1001 can include complementary snap-fit ​​connectors that allow it to snap into the folding screen module. FIG. 11 shows a portable electronic device with a snap-fit ​​main body. If any module is damaged, it can be easily replaced. The damaged module can be sent for repair. The main body allows for greater waterproofing than would be possible with a fully integrated device. FIG. 12 shows a front view of the device of FIG. 11.

[0033] Those skilled in the art will understand that the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. Accordingly, the foregoing description is intended in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalents thereof are intended to be embraced therein.
