    摘要： A colour cathode ray tube including a screen (16) comprising at least two sets of phosphor stripes luminescing in different primary colours. A channel plate electron multiplier (44) is mounted parallel to, but spaced from, the screen (16). The electron multiplier (44) comprises a stack of juxtaposed substantially planar apertured dynodes (DI to Dn) with the apertures therein aligned to form channels. An apertured extractor electrode (48) is mounted on the output side of the electron multiplier (44). Preferably two or more foraminous deflector electrodes (50, 52) are mounted on the extractor electrode. The apertures in the foraminous deflector electrodes (50, 52) have the same pitch as the channels of the electron multiplier but are offset laterally relative to each other and to the axes (A) of the channels by amounts which allow the emergent electron beam from each channel to pass through to the screen (16) without impinging upon the deflector electrodes (50, 52). By applying a potential difference between the deflector electrodes (50, 52) an electron beam emerging from its respective channel is deflected laterally onto a respective one of its associated group of phosphor stripes. The apertures in the deflector electrodes (50, 52) may be circular, elliptical or polygonal for example square, rectangular or hexagonal.
