  • Patent number: 7956820
    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.

  • Patent number: 7446744
    Abstract: The invention relates to a display device comprising a plurality of light emitting elements (1), wherein at least one of the elements has an associated capacitor (C1). The display device comprises pre-charging means (7;8) for generating a pre-charge signal for charging the associated capacitor (C1) at least partly. The pre-charging means (7;8) are adapted for generating a pre-charge signal comprising at least a first pre-charge signal in a first pre-charge stage and a second pre-charge signal in a second pre-charge stage. The pre-charge signal preferably comprises a current pre-charge signal followed by a voltage pre-charge signal. The combined pre-charge signal has the advantage of fast, but accurate pre-charging.

  • Publication number: 20050280766
    Abstract: The invention relates to a display device for displaying an image comprising a plurality of display pixels (2), a controller (3) for generating a driving signal (8) for driving the pixels (2), and sensors (9; 11; 14), wherein the sensors (9; 11; 14) are able to monitor operating conditions of the pixels (2), and the controller (3) is adapted to receive data related to the operating conditions from the sensors (9; 11; 14) to determine a brightness change of the pixels (2) caused by the operating conditions and to generate the driving signal (8) in dependence on the brightness change.
