Abstract: 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.

Abstract: The present invention relates to a device for mechanically deforming cells comprising: a cell holding element (33) for holding a cell (32) in a cell holding zone, a micro-actuator (31) for applying a force on the held cell (32), wherein said micro-actuator (31) can be electrically, thermally, photonically or magnetically actuated and wherein the micro-actuator (31) applies said force on the cell (32) in a non-actuated or an actuated state, and a stimulation unit (35) for electrically, thermally, photonically or magnetically actuating said micro-actuator (31).

Abstract: A system comprises a rollable sheet (SH) forming a loop. The rollable sheet has a first section (SH1) forming a first optically addressable bi-stable display and a second section (SH2) forming a second optically addressable bi-stable display, the first section (SH1) and the second section (SH2) are electrically isolated. A rotating unit rotates (SP1, SP2, M1) said sheet (SH), wherein in a first position (P1), the first section (SH1) is viewable while the second section (SH2) is hidden, and in a second position (P2), the second section (SH2) is viewable while the first section (SH1) is hidden. A changing unit (VG1, VG2, AD, CO) changes a first image on the first section (SH1) while displaying a second image on the second section (SH2) when in the second position (P2), and for changing the second image of the second section (SH2) while displaying the first image on the first section (SH1) when in the first position (P1).
