[0058] figure 1 The fluorescent display tube of the present invention has a box-shaped enclosure whose interior is kept in a high vacuum state. The enclosure is formed by sealing the anode substrate 100 , side panels 200 ( 201 , 202 ), and front panel 300 with a sealing member 800 .

[0059] Inside the aforementioned airtight container, there is a frame portion 500 for fixing the filament 400 on the upper surface of the aforementioned anode substrate 100. In the aforementioned frame portion 500, the filament 400 supported by the anchor 600 as a filament support body is stretched on the aforementioned In an airtight container.

[0060] In the anode substrate 100 inside the peripheral, an anode 110 with a phosphor layer formed thereon is formed on the upper surface of a glass plate which is an insulating substrate, and a control electrode (not shown) is provided so as to cover the anode. Above the control electrode, a plurality of filaments 400 that emit electrons are arranged...

[0076] exist figure 2 , image 3 A fluorescent display tube of a second embodiment of the present invention is shown. Since the shape of the support holding part 510 as the mounting part of the anchorage figure 1 The fluorescent display tube of the first embodiment shown is different, so the difference from the first embodiment will be described below. The rest are the same as the first embodiment.

[0077] The supporting body holding part 510 of the fluorescent display tube according to the second embodiment of the present invention is provided with an anchor drooping avoiding part 511 formed such as along the shape of the anchor drooping part 603 of the aforementioned anchor 600, and is formed with an avoiding part 512. The notch portion 513 is formed, and the avoiding portion 512 is formed in a shape separated from the adjacent anchor hanging portion 603 .

[0078] By providing the notch 513 in the support body holding part 510, the anchor base 604 is fixed on the upp...

Abstract

The purpose of the invention is to provide a fluorescence display tube with low arranged filaments and more filaments for increasing pattern range. For low arranging filament-shaped cathodes in a airtight container of the fluorescence display tube, a filament anchorage device is suspendedly arranged in front of a trapezoidal frame, a supporting body maintenance part formed by extending the frame to side panel direction is arranged, so that more filaments can be arranged. Simultaneously, a unit for a semiconductor for driving is mounted between the filaments supported by the supporting body maintenance part and a anode substrate, thereby providing a novel built-in chip type fluorescence display tube.

Description

technical field [0001] The present invention relates to a fluorescent display tube having a filament supporting structure including an anode forming a phosphor layer and a filament serving as a cathode in a vacuum airtight container. Background technique [0002] A fluorescent display tube is a self-illuminating unit, an anode substrate having an anode layer with a phosphor layer formed on the upper surface of an insulating substrate, a side panel, and a front panel are bonded together with low-melting glass to form an airtight container, and A filament that emits thermal electrons is provided in the airtight container, and a phosphor receiving the thermal electrons emitted by the filament emits light. [0003] The luminous brightness of the fluorescent display tube generated by the light emission of the phosphor is determined by the distance between the phosphor layer and the filament, or in the case of a fluorescent display tube having a grid electrode around the phosphor ...
