Abstract

A variable stiffness screen with a pneumatic frame for wearable electronic devices provides a viewable area that can be adjusted by managing the screen'"'"'s physical properties. The screen incorporates a flexible electronic display, attached to a pneumatic frame, in which the structural properties can be changed from a flexible state to a rigid one to control the stiffness of the display.

Claims

1. A variable stiffness screen comprising a flexible electronic display attached to a pneumatic frame and providing means for changing said screen'"'"'s properties from flexibility to rigidity to make said display stiff and stable.

2. The screen of claim 1, further including a carrying member encasing said screen;

wherein said screen functions in a closed position inside said carrying member and in an open position, where said display is fully visible to the user.

3. The screen of claim 2, wherein said screen is coupled to said carrying member by means of a pullback winding mechanism, which includes locking means allowing to secure said screen automatically in said open position.

4. The screen of claim 2, wherein said carrying member is a flexible flat sleeve having a rectangular opening revealing a respective part of said display, and incorporating an embedded electrical circuitry.

5. The screen of claim 2, wherein said carrying member is a rigid case comprising a flat part with said rectangular opening and an adjacent cylindrical enclosure housing a rolled-up part of said screen, and said case includes said embedded electrical circuitry.

6. The screen of claim 1, wherein said means for changing said screen'"'"'s properties from flexibility to rigidity comprise a pneumatic frame.

7. The screen of claim 7, wherein said pneumatic frame includes a conduit assembly and a handle assembly.

8. The screen of claim 8, wherein said conduit assembly is formed of two air-impervious pieces bonded together in such a way as to create a plurality of sealed tubular conduits.

9. The screen of claim 8, wherein said handle assembly includes means for inflating and deflating said tubular conduits.

10. The screen of claim 10, wherein said means for inflating said tubular conduits include a pneumatic pump associated with check and release valves, all interrelated with each other and said interior chambers.
