Hand-held electronic device and protective case
A hand-held electronic device including a display device and an optical film is provided. The display device includes a display light source and displays information by a display light emitted by the display light source. The optical film is disposed on the display device. The display light emitted by the display light source for displaying the information is deflected by an angle after passing through the optical film to project the information on a display surface outside the display device. A protective case for protecting the hand-held electronic device is also provided.
1. A hand-held electronic device, comprising:
a display device comprising a display light source and displaying information on a surface of the display device by a display light emitted by the display light source;
an optical film disposed on the display device, wherein the optical film is attached onto the surface of the display device and the display light emitted by the display light source for displaying the information is deflected with an angle by passing through the optical film to project the information on a display surface outside the display device;
a back housing covering a back side of the hand-held electronic device opposite to the display device; and
an upper cover pivotally connected with the back housing and pivotally rotatably covering the display device, wherein the optical film is pivotally connected with the back housing through a pivot and the optical film is attached to the surface of the display device in a pivotally rotatable manner.
2. The hand-held electronic device according to claim 1 , wherein the optical film is directly attached to the surface of the display device.
3. The hand-held electronic device according to claim 1 , wherein the optical film comprises a plurality of optical microstructures, and the display light emitted by the display light source is deflected by the angle by passing through the optical microstructure of the optical film.
4. The hand-held electronic device according to claim 1 , wherein the optical film is a light-reflecting film.
5. The hand-held electronic device according to claim 1 , wherein the hand-held electronic device is a smart touch mobile phone or a tablet computer.
6. The hand-held electronic device according to claim 1 , wherein the display surface comprises a wall, a projection screen, or other projection planes.
7. A protective case for protecting a hand-held electronic device comprising a display device that comprises a display light source, the protective case comprising:
a back housing, in which the hand-held electronic device is housed, covering a back side of the hand-held electronic device opposite to the display device;
an upper cover pivotally connected with the back housing and pivotally rotatably covering the display device; and
an optical film disposed on the display device, wherein the display device displays information on a surface of the display device by a display light emitted by the display light source, the optical film is attached onto the surface of the display device and the display light emitted by the display light source for displaying the information is deflected with an angle by passing through the optical film to project the information on the upper cover;
wherein the optical film is pivotally connected with the back housing through a pivot and the optical film is attached to the surface of the display device in a pivotally rotatable manner.
8. The protective case according to claim 7 , wherein the upper cover is a translucent cover or a non-transparent cover.
