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).

摘要： A display device comprises a cathode ray tube (1) with an electron gun (5) for generating at least one electron beam (6) by means of a cathode, a phosphor screen (8) on an inner surface of a display window (2) and a means (9, 27, 28) for deflecting the electron beam(s) across the phosphor screen. The electron gun comprising a pre-focusing part (11), a main lens part (12) and between the pre-focusing part and the main lens part an intermediate electrode (23, G3, G3B) and a means for reducing ion cathode damage by ions (30) generated in or near the intermediate electrode. The electron gun (5) is provided with a means (41, 42, 51, 54) for generating inside the intermediate electrode (G3, G3B) an electrical field that comprises on a beam axis a component perpendicular to the beam axis. This leads the ions away from the electron beam and reduced the damage to the cathode in an efficient manner.

摘要： The invention relates to a method of providing images on a screen and to an image projection device. The image projection device (10) comprises at least one first set (12) of light-emitting units provided in an array including at least two lines of light-emitting units having at least two light-emitting units each, and a light-displacing unit (36) arranged to displace the light from each light-emitting unit before projection on a screen (16), such that each light-emitting unit provides a tile comprising a line including at least two pixels aligned in one direction on the screen. The light-emitting units are preferably LEDs, and in this way, an efficient display or projector that can be accommodated in a reasonably small space is provided.
