    摘要: A plasma display apparatus comprises a waveform generator (WG) coupled between first and the second electrodes (SEl, CEl) to supply, across plasma cells (PCij), a sustain voltage (VCP) with slopes comprising a main part (MA) and a minor part (MI) succeeding the main part (MA). The main part has a duration longer than a formative time 5 lag (FTL) of the plasma cells (PCij), and the minor part has a smaller amplitude than the main part (MA). The plasma cells (pCij) are ignited and sustained by the minor part (MI). The main part (MA) has less steep slopes than the prior-art waveform. Consequently, the EMI produced by the main part (MA) will be at a lower frequency. The minor part (MI) has an amplitude which is relatively low and thus does not add considerably to the EMI, even 10 when its slopes are relatively steep. As the plasma is neither ignited nor sustained by the main part (MA), the main part (MA) further has a lower amplitude than the slope of the prior art and thus produces less EMI.

    摘要: The display panel (21) comprises a light guide (2), a second plate (4) and a movable element (3) between both plates for locally decoupling light out of the light guide (2). Voltages, applied to electrodes (5,6 resp. 25), associated with the light guide (2), the second plate (4) and the movable element (3), locally bring the movable element (3) into 5 contact with the light guide plate (2) or the second plate (4). If, between the light guide (2) and the first electrodes (5) a layer (51) is present with a second refractive index being smaller than the first refractive index of the light guide (2), and the light guide (2) is positioned between the first electrodes (5) and the movable element (3), absorption of the light transported through the light guide plate (2) is reduced, providing a display panel (21) with 10 improved power efficiency.

    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.

    摘要: The present invention relates to a light valve (40) for reflecting and diffracting incident light, comprising an electrostatically operable foil (42) provided with a reflective surface (60), a reflective grating structure (52) provided on one side of the foil (42), and means (48, 56, 60) for inducing electrostatic forces on the foil (42) for switching it between a first position, in which the foil is separated from said grating structure (52), whereby incident light (64) received by said light valve (40) will be diffracted by said reflective grating structure (52), and a second position, in which the foil is brought into contact with said grating structure (52), whereby incident light (64) received by said light valve (40) will be essentially specularly reflected by said foil electrode (60). A grating structure having no movable parts may thus be used, which makes the light valve easy to manufacture. The invention also relates to an imaging system comprising at least one such light valve.

    摘要: The invention relates to an electrostatic deflection system for deflecting an electron beam (132), and to a matrix display device provided with such an electrostatic deflection system. The deflection system has deflectors (112, 114) for the horizontal and vertical directions, and a focus electrode (110). By applying a sufficiently high voltage difference of for example several kilo Volts between the focus electrode (110) and at least one of the deflectors (112, 114), a bipotential type focusing electron lens is integrated with the deflection system. Thereby, the system achieves simultaneous deflection of the electron beam (132) and focusing of the electron beam onto a surface (140) to be scanned. In a matrix display device, the electron beam (332) may be kept in focus on the display screen (340) thereby obtaining a relatively small spot size and high image quality. Generally, the display screens divided into a number of portions (344). In operation, each portion is scanned by a separate electron beam (332).
