1. A mobile display device comprising:
- a display configured for displaying an upright image in two or more operative orientations, each operative orientation having associated therewith a display edge that is positioned in an uppermost orientation;
one or more orientation sensors;
a plurality of photosensors configured to detect ambient light, wherein at least one photosensor is located proximal to each said display edge; and
processing circuitry operatively connected to said display, said orientation sensors, and said photosensors;
wherein said processing circuitry is configured to;
identify the operative orientation of said device with respect to gravity in response to input provided from said orientation sensors;
identify the uppermost display edge corresponding to the identified operative orientation;
display an upright image on said display; and
control said display according to input from one or more photosensors proximal to the identified uppermost display edge.

Abstract
Devices and methods are provided for controlling a display of a portable display device based on input form a plurality of ambient light photosensors positioned proximal to edges of the display. The display device includes one or more orientation sensors configured such that processing circuitry of the display device may determine, based on input from the orientation sensors, an operative orientation of the device relative to gravity, and subsequently identify an uppermost display edge. Signals from the ambient light photosensors proximal to the uppermost display edge are employed to control the display.
