    • 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 kiloVolts 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,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。
