Abstract: One aspect provides a method for image display. The method for image display, in accordance with one embodiment, includes providing a display, the display having a maximum display area (Amax) defined by a total number of pixels. The method for image display, in accordance with this embodiment, may further include activating, in an attempt to extend battery life, less than all of the total number of pixels of the display to provide a modified display area (Amod) that is less than the maximum display area (Amax).

Abstract: A mobile computing device comprising a noncontact location sensor operable to detect the presence of an input object that enters a detectable region proximate to the touch screen panel. The sensor can produce location signals representing the location of the input means relative to a plurality of virtual input characters. Based on the location signals, a target virtual character can be identified and magnified to a more recognizable and accessible size before a user makes an input selection. Optionally, a series of virtual characters adjacent to the target character may also be magnified to facilitate the user to locate the desired character and improve user input accuracy. The noncontact location sensor may comprise an infrared location sensor, an optical sensor, a magnetic sensor or a combination thereof.

Abstract: In various embodiments, a handheld mobile device and back cover for the same are provided. The back cover for a handheld mobile device comprises: a back cover body having a first surface and a second surface opposite to the first surface; and a heat dissipating plate fixed to the first surface of the back cover body; wherein a hole is provided in a region of the back cover body corresponding to the heat dissipating plate. The heat dissipating plate covers the heat-generating elements on the circuit board, and the heat dissipating plate is partly exposed to the outside via the corresponding hole in the back cover body, such that the heat dissipating plate eliminates the partial heat-generating points and dissipates heat to the outside via the hole effectively.
