Abstract
A display device is provided with a display screen (30) for displaying image information, having a predetermined number of luminescent picture elements (35). In operation, an electron beam (45) is generated by an electron gun (40) and entered into a two-dimensional slalom guide (10), wherein the beam is guided in two mutually perpendicular directions by means of slalom focusing. Subsequently, the electron beam (45) is extracted from a selected cell (56) of the slalom guide (10) towards a corresponding picture element (35). The path of the electron beam (45) in the slalom guide (10) can be fully customized within the guidance plane. Preferably, the guidance plane extends substantially parallel to the display screen (30).
Claims13
A display device, comprising:
- a display screen (30) for displaying image information, having a predetermined number of luminescent picture elements (35);
- an electron gun (40) for generating an electron beam (45) and
- an electron beam guide (10) for receiving the electron beam (45) at a beam entrance (14) and guiding said electron beam (45) along a beam path to extraction means for extracting said electron beam (45) from said beam guide (10) towards a predetermined picture element (35) of the display screen (30), characterized in that the electron beam guide (10) comprises a two-dimensional slalom guide, while said extraction means are arranged to extract said electron beam (45) from said two-dimensional slalom guide.
