がまさに開いているところである。Recent advances in electronics technology centered on semiconductors have been remarkable (industrial robots), so-called mechatronics fields such as NC machine tools, display fields that use various display elements such as liquid crystals, fluorescent display tubes, and light-emitting diodes. There are video information equipment fields such as mata cameras, video tape recorders, cathode ray tubes, etc., all of which belong to the cutting-edge high technology field.
It is said that this is a field that will continue to develop and grow rapidly in the future. In particular, the bright future prospects for video information equipment include new broadcasting systems (SHF, teletext, captain, etc.), high-definition televisions, personal computers, and even car electronics.

おり、外観的には液晶。Display elements such as cathode ray tubes, fluorescent display tubes, liquid crystals, etc. are necessary for this video information equipment, and progress is being made in two main directions: larger sizes and smaller sizes. Market competition in the direction of miniaturization is becoming more and more intense, apart from the direction of larger size, and development competition is not just in terms of quantity but also in terms of quality, such as thinner thickness and lighter weight. I can say that there is. Recently, so-called wall-mounted televisions, which were a hot topic in the past, have been once again being developed and researched both domestically and internationally, along with the subsequent development of liquid crystals, plasma light emitting diodes, and even fluorescent display tubes. However, because liquid crystals each have fundamental issues such as colorization and fluorescent display tubes have issues with resolution, neither has been fully put into practical use at present. By the way, as an application technology for cathode ray tubes, flat type cathode ray tubes have been put into practical use and are now on the market, but while this is fine for black and white, it has to be said that practical use is still a long way off when it comes to color. On the other hand, as a cathode ray tube (hereinafter abbreviated as CRT) application,
The cathode luminescence (electron acceleration) method has extremely superior resolution and brightness compared to the various display elements mentioned above, and has a liquid crystal appearance.

る。Based on the above background, the present invention uses the main cathodoluminescence method (electron acceleration method), that is, heats the cathode to emit thermoelectrons, accelerates the emitted electron beam, and lands the final phosphor. In view of the fact that the method of emitting light is superior to other methods in terms of both resolution and brightness, the present method is adopted to provide a new display device.

Among these, the shadow mask 1o has a structure in which a stud supported by a knob is attached in the panel 11, and a hole in the support spring portion of the shadow mask engages with the stud. Docking between panel 11 and funnel 12 with 10 attached is as follows:
Previously, they were fixed with adhesive using epoxy resin, but in recent years they have been tightened with metal rings made from Sierlink. Here, 13 is an electron gun, and 14 is a magnetic device.
