Abstract: A personal computer (PC) includes a main body, a processor received in the main body, and a projecting unit received in the main body and electrically connected to the processor. The PC does not include a built-in display. The processor transmits image signals to the projecting unit, the projecting unit projects images onto a nearby projection surface corresponding to received image signals, so that the nearby projection surface serves as a display of the PC.

Abstract: An electronic device and a method for controlling an user interface thereof are provided. The method includes detecting an orientation of the electronic device, determining a arrangement of the user interface according to the detected orientation, displaying a shortcut key area and a status area on the user interface, and adjusting the user interface according to the operational signals from a touch panel of the electronic device.

Abstract: A film comprises a base layer, a first patterned layer and a second patterned layer. The base layer includes a first surface and a second surface opposite to the first surface. The first patterned layer is laminated with the base layer partially over the first surface of the base layer. The first patterned layer is belt-shaped and includes a plurality of spaced first strip patterns, such that a first interval space is defined between adjacent two first strip pattern. The second patterned layer is laminated with the base layer partially over the second surface of the base layer. The second patterned layer being belt-shaped and includes a plurality of spaced second strip patterns corresponding to the first strip patterns. The second strip patterns are partially overlapped with corresponding first strip patterns and the rest of the second strip patterns are partially overlapped with corresponding first interval spaces.
