    • 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).
    • 本发明涉及一种用于偏转电子束(132)的静电偏转系统,以及具有这种静电偏转系统的矩阵显示装置。 偏转系统具有用于水平和垂直方向的偏转器(112,114)和聚焦电极(110)。 通过在聚焦电极(110)和至少一个偏转器(112,114)之间施加足够高的例如几千伏特的电压差,将双电位型聚焦电子透镜与偏转系统集成。 因此,该系统实现电子束(132)的同时偏转和电子束聚焦到待扫描的表面(140)上。 在矩阵显示装置中,可以将电子束(332)聚焦在显示屏(340)上,从而获得相对较小的斑点尺寸和高图像质量。 通常,显示屏幕被划分为多个部分(344)。 在操作中,每个部分由单独的电子束(332)扫描。

    • The display apparatus comprises a picture tube (CRT) with an electron gun which generates an electron beam (BB) directed towards a display screen. The electron gun comprises a first and a second electrode (CA, G1). The electron beam (EB) originates from the first electrode (CA). The voltage between the first electrode (CA) and the second electrode ( G1) controls the intensity of the electron beam (EB). A beam current (IB) flows in the first electrode (CA) in response to the electron beam (EB). A (ICA) in the first electrode (CA) is the sum of the beam current (IB) and a current (IC) flowing through a capacitance (CWN) between the first and the second electrode (CA, G1). A compensation circuit (COM) supplies a compensation current (ICO) to the first electrode (CA) to compensate for a capacitive current (IC) through a capacitance (CIN) between the first and the second electrode (CA, G1). A beam current measurement circuit (BMC) measures the total current (IT) which is the sum of the total current in the first electrode (ICA) and the compensation current (ICO).

    • The invention relates to a lighting device (1) comprising a lighting unit (2) and a user interface (3) for controlling the lighting colour and/or intensity of the lighting unit (2). The user interface (3) comprises a sensing device (5) with a large number of conductive elements (6), which responds to the proximity of a conductive object, like for instance a human finger pointing to the user interface (3). The user interface (3) can be based on proximity sensing or on touch-control. In both cases an element (6) on the outer surface (4) of the user interface (3) is selected, which corresponds to one of the selectable colours and/or intensities of the lighting unit (2). The selected element (6) generates an output signal which is sent to a processing unit (9), which converts this output signal into a driving signal suitable for the driver circuit (8) to drive the light sources (7).

    • The present invention relates to a display device (100) arranged to operate in two different modes: a transparent mode and a display mode. The idea of the present invention is that a transparent plate (101) is provided with a plurality of light emitting means (102). The light emitting means are arranged in a grid which defines the pixels of the display device. The area of each light emitting means must be small compared to the area (104) of the corresponding pixel it illuminates, since the plate provided with the light emitting means must appear transparent to the human eye. A first switchable diffuser (103) is placed in front of the plate. Thus, the display device will appear virtually transparent when the diffuser is operated in the transparent mode, whereas when operated in the display mode, the light emitted from the light emitting means will be diffused and result in uniform pixels of the display device.
    • 本发明涉及一种布置成以两种不同模式操作的显示设备(100):透明模式和显示模式。 本发明的目的在于,透明板(101)具有多个发光装置(102)。 发光装置布置成限定显示装置的像素的格栅。 由于设置有发光装置的板必须对人眼透明,所以每个发光装置的面积必须小于其照亮的相应像素的面积(104)。 第一可切换扩散器(103)被放置在板的前面。 因此,当扩散器以透明模式操作时,显示装置将显现为实质上透明的,而当在显示模式下操作时,从发光装置发射的光将被扩散并导致显示装置的均匀像素。
