The present invention relates to a display device comprising an outer display stacked with an inner display and being arranged to be operable in a first, multiple view mode and a second, single view mode. An idea of the invention is to arrange an electrophoretic display on top of an emissive display. The display device may be operated in two modes; a first mode being a multiple or dual view mode and a second mode being a single view mode. In order to activate the single view mode, the outer display is set in a transparent state and the inner display is turned on, such that it displays desired objects. In the multiple view mode, the outer display is functioning as a 3D-barrier. Hence, some of the picture elements of the outer display are set in a transparent state while others are set in an opaque state. The viewer sees a different picture with each respective eye, and will accordingly experience a multiple view picture of an object that is displayed on the inner display.

Combined single/multiple view-display

Bi-stable electrophoretic display device () having a normal mode and a scrolling mode, in which image transitions are effected by causing the charged particles () to toggle between the intermediate optical states (e.g. grey-to-grey) or between an extreme optical state and an intermediate optical state (e.g. white-to-light grey), with a corresponding short update time t. When the device () enters a scrolling mode in response to a scrolling command from a user, picture elements are first driven to a special scrolling optical. state, after which drive waveforms for scrolling mode are used for fast toggling between two scrolling states. An increased scrolling speed and very short scrolling time can be realized, without adversely affecting image quality during a normal mode.
