摘要： A display tube assembly is provided, in which plug pins are mounted on a printed circuit board, this printed circuit board having the plug pins soldered thereto is attached to a display tube and the display tube is accommodated in a case thereby being made watertight. According to this arrangement, the plug pins, the printed circuit board and the display tube are coupled together in the outside of the case so that a working property in the assembly process can be improved considerably. Further, since a window portion is not provided at the rear surface of the case, the reliability in the watertight process in the display tube can be improved considerably.

摘要： A fluorescent display apparatus includes display cells of a first type consisting of several sets of fluorescent display segments of various colors arranged in a certain order and display cells of a second type consisting of display segments equal in number and color, but opposite in the order of arrangement of colors, to the first display cells. The first and second display cells are arrayed in a matrix fashion with their lead lines aligning alternately with the intention of reducing areas used for the bend of lead lines and thereby arranging the cells closely so as to enhance the resolution of display.

摘要： A luminescent display cell comprising a glass envelope having a front panel, a side wall, and a rear plate. Plural luminescent display segments are formed on the front panel of the glass envelope, the display segments being supplied with an anode voltage. Plural cathodes are arranged on the rear panel side of the glass envelope in corresponding relation to the display segments. Plural control grid electrodes are arranged between the display segments and the cathodes in corresponding relation to the display segments. A common accelerating electrode is disposed between the display segments and the control grid electrodes. The voltage applied to each control grid electrode is controllable for electron emission from the cathodes so as to render each display segment corresponding to each control grid electrode selectively luminous for display. Furthermore, a separator surrounds each display segment and it is supplied with the above anode voltage so that diffusion lens is formed which allows the electron beam from the cathode to be spread laterally and radiated to the entire surface of the display segment to be rendered luminous.

摘要： An electron beam indicator, for example, for a large-screen display which has a two-dimensional arrangement of a plurality of electron beam indicators. The electron beam indicator tube comprises fluorescent trios each of which have a plurality of fluorescent layers which function as picture elements, and a plurality of linear cathodes which are disposed respectively opposite to the fluorescent layers of the fluorescent trios. A common accelerating electrode is disposed between the fluorescent trios and control electrodes, and a separator structure is disposed so as to shield the fluorescent layers of each fluorescent trio. The common accelerating electrode is curved in the direction which the linear cathodes extend in a convex shape which bulged outwardly toward the fluorescent layers, and is formed so that the width of the electron beam transmission apertures decreases from the central portion toward the opposite ends. The electron beam which impinge on the separators of the separator structure are cut off by the accelerating electrode to which a low voltage is applied and hence the reactive current is reduced and luminous efficiency of the fluorescent layers is improved and the power consumption is reduced.

摘要： A luminescent display tube wherein a plurality of luminescent trios and a plurality of electrode units corresponding thereto are disposed opposite to each other in a single housing, and a member forming an enclosure of each electrode unit functions also as an accelerating electrode. The invention realizes a high-luminance display tube or display cell of a small-sized structure which incorporates a plurality of luminescent trios serving as picture elements and electrode units corresponding thereto. Consequently, it becomes possible to construct a large-picture display apparatus of moderate dimensions by arraying a multiplicity of such display cells. Furthermore, a plurality of wire cathodes and first grids as well as a common second grid are grouped into an electrode unit with its enclosure functioning as the second grid, and such electrode units are arrayed correspondingly to individual luminescent trios, thereby facilitating assembly and manufacture of a desired display cell. In the electrode units constituting the display cell, each of the first grids is positioned and set by an insulator substrate and a pair of insulator walls in each unit, without any other means such as spot welding, so that the electrode unit can be produced in a sufficiently small structure, hence ensuring remarkable facility in assembly and manufacture of such small-sized display cell.
