Abstract: A method, apparatus and computer program product for controlling a cursor on a display screen is disclosed. The initial area of contact of a portion of an object positioned on a touch-sensitive pad is detected. Whilst contact is maintained at substantially the same position on the pad, a change in the area of contact caused by relative movement about said position is detected. A cursor is then positioned on the display screen such that changes in the area of contact in a first direction cause the cursor to move in a first direction.

Abstract: To produce a paper like display a diffuser 28 is mounted on on the front substrate 12 of a display cell which is also provided with a reflective pixel electrode on the other substrate 14. The diffuser is preferably a volume or surface relief hologram and provides a low backscatter. The display includes an electrooptic medium which may be liquid crystal, electrochromic or electrophoretic and is specularly reflective or weakly scattering..

Abstract: An electrochromic display device has an improved counter electrode arrangement. The device has a plurality of display elctrodes and a counter electrode in contact with a first electrolyte of a primary redox system. The counter electrode is charged to a predetermined potential. A secondary redox system is associated with the primary redox system. A secondary electrode in the secondary redox system is electrically connected to the counter electrode to maintain the charge on the counter electrode at a predetermined potential.
