    摘要: A cathode ray tube includes an electron gun having a beam-shaping portion (20) for generating electron beams (7-9), a prefocusing system (30) of electrodes (31, 32) across which a prefocusing voltage is supplied during operation so as to form an electron-optical prefocusing lens, and a main lens system (40) of electrodes (32, 41) across which a main lens voltage is applied during operation so as to form an electron-optical main lens. The electrodes (31, 32, 41) are provided with securing means (48) for connection to an insulating supporting body (47) and with apertures (16) for passing the electron beams (7-9). Electrode (32) protrudes toward electrode (31) in such a way that the mutual distance (l2) between the two electrodes at the location of the apertures (16) therein is smaller than their mutual distance (l1) at the location of their respective securing means (48). The two electrodes (31, 32) are spaced apart at the location of the apertures (16) substantially at a distance limited by electrostatic breakdown.

    摘要: A phosphor screen in a display device is scanned by separate electron beams in order to generate images of different frequency content in one color in substantially the same part of the phosphor screen. The different images can be perceived as a composite image for some time. The individual electron beams can be modulated by means of a cathode modulator on the basis of a high frequency and a low frequency component of an electronic image signal or on the basis of an image component and a text component of an electronic image signal. The modulations of the individual electron beams may be slightly delayed relative to one another in order to avoid overloading of the phosphor material.

    摘要: The invention relates to an apparatus for receiving programs from a plurality of channels, comprising a tuner for tuning to any of the plurality of channels, and an electronic program guide (EPG) for presenting a schedule of the programs. The apparatus comprises virtual channel means for creating a user selectable virtual channel for reproducing selected programs from various genuine channels. The virtual channel means are adapted to control the tuner to tune to a channel currently broadcasting a selected program. When a user selects the virtual channel, the apparatus takes care of automatically switching between the genuine channels broadcasting the programs viewed on the virtual channel. As a consequence, the user can view the desired programs by simply selecting the virtual channel.
