Abstract

A display with orientation dependent rotatably image presents a properly oriented image in a first mounted fold-down position and a second up-right table-top position. The display folds up into a base unit when not being used for compact storage of the system. An orientation determining device is included for determining the current orientation of the display and properly orienting the image based on that current orientation. The orientation determining device is either a mechanically flipped switch, an automatic switch or an acceleration sensor. The display screen is preferably an LCD screen. Alternatively, the display screen is a light valve type display including a grating light valve system. The display is for use in a television system, computer system, video phone or browser. Infrared input devices are used to control the display and provide data to the computer system. In an alternate embodiment, a touch sensitive screen is also used as an input device.
