    摘要: The invention relates to a field emission device, and a method of manufacturing same. The field emission device comprises a gate electrode (140, 340, 440) which is provided with a pattern of electron passing apertures (135, 335, 435). The gate electrode (140, 340, 440) is arranged near particles (110, 310, 410) distributed on a substrate (125, 325, 425), at least a part of said particles (110, 310, 410) being arranged for emitting electrons. By means of the gate electrode (140, 340, 440), an electric field is applicable by means of which emitting particles emit electrons. Particularly good electron emission is obtained, because the pattern of apertures (135, 335, 435) is similar to the distribution of particles (110, 310, 410) on the substrate. This is achieved by means of the manufacturing method, in which the particles (110, 310, 410) are used in an illumination step to mask regions (155, 355) of a photo layer (150, 352). Thus, a pattern is obtained in the photo layer (150, 352), which can be used to obtain a similar pattern in the gate electrode (140, 340, 440) with relative case.

    摘要: A display device comprising a light guide (12), a front plate (14), and an intermediate electromechanically operable foil (16). Two electrode layers (22, 23) are arranged on either side of the foil (16) to induce electrostatic forces on the foil (16) and to bring selected portions of the foil into contact with the light guide (12), thereby extracting light from the light guide (12). The second electrode layer (22) is arranged on the opposite side of the light guide (12) with reference to the foil (16), and separated from the light guide (12) by means of a refractive layer (28). As no electrode layer is required on the light guide itself, the light path of rays extracted from the light guide is cleaner, and the absorption of light is reduced. The light guide can have a thickness such that the light extracted from the light guide per unit length is sufficient to allow for line-at-a-time addressing

    摘要: A display for displaying and storing images comprises an optically addressable electrophoretic display (PD) with a stack of a photoconductive layer (PCF) and an electrophoretic layer (EF) being sandwiched between electrodes (E1, E2). An optical addressing means (AD) supplies addressing light (AL) to the photoconductive layer (PCF). A controller (CO) controls a driver (DR1) to supply a drive voltage (DV) between the electrodes (E1, E2) with a value enabling a change of the optical state of the electrophoretic layer (EF) in response to the addressing light (AL) impinging on the photoconductive layer (PCF). Finally, the power consumption of the optical addressing means (AD) is minimized.

    摘要: The invention relates to a method of controlling a display screen, particularly a foil display built up of a number of lines, the display screen comprising at least one light source, a movable element, and selection means for locally bringing the movable element into contact with the light source, in which the selection means comprise row and column electrodes and means for applying control voltage signals to the invention also relates to a display source, a movable element, and selection means for locally bringing the movable element into contact with the light source, in which the selection means comprise row and column electrodes and means for applying control voltage signals to the row and column electrodes. Because of a minimum switching time of pixels, not all pixels, i.e. lines can be activated immediately when the display screen is addressed line by line. To avoid this problem, the invention provides a novel addressing method comprising the step of addressing a group of lines or a part of a group of lines while the light source is switched off, followed by a step of illuminating the display screen for a predetermined interval by switching on the light source.
