Abstract: The invention provides a flat display supporting mechanism for a portable input/output device such as a computer or a word processor which employs a flat display having a large display area formed in a flat plate profile with a pivotable link attached between a back portion of the display and a device body. The device has a flat profile in a closed position. When the device is to be used, the display which is covering a keyboard is pivoted upwards together with the link. As the display reaches a vertical position the link having two pivot points around which the display is pivoted separates from the display and a lower portion of the flat display is moved away from the pivot point and towards the keyboard along a guide provided on the device body to a position where the flat display is positioned near the keyboard on the device body while a center portion of the display is supported by the link.
