Problems solved by technology
[0005] According to the analysis of the literature, although the schemes of changing the incident direction of the electron beam and thinning the CRT proposed by various companies in the past are different, the basic principle of controlling the movement of the electron beam in each scheme is the same as that of the traditional CRT, and its structure is also similar. encountered common difficulties that were difficult to overcome
These difficulties are: (1) It is difficult to correct the curved grating and fan-shaped distortion on the flat display screen, and the display image forms a fan-shaped surface; (2) It is difficult to achieve consistent focusing of the electron beam on the entire display plane, and it is difficult to obtain high-quality images ; (3) The process is difficult and difficult to achieve colorization
Because of the above reasons, thin, flat panel display CRT research has been unsuccessful

Embodiment Construction
[0051] In order to make the EBPDP display panel serve the economic construction of our country as soon as possible, and to create a new industry in the field of information display in our country, we suggest organizing forces to develop this new product in the form of a combination of industry, education and research. During the research and development process, the factory that originally produced CRT should participate, so that the research and development process can be accelerated, and this new product will be displayed in front of the world within 2-3 years.

At present, liquid crystal display and plasma display vigorously develop, and the traditional cathode ray tube (CRT) faces a large challenge. In order to overcome the defect of the CRT, the research work for thinning and flatting the CRT lasts more than 50 years until now. Owing to the reasons of a principle, three problems are unable to solve, namely, the arc grating and the fan-shaped aberrance on a flat display screen are difficult to revise, electron beams are difficult to consistently focus on a plane, the technical difficulty is large, and the flat display screen is difficult to colorize, so the research is not unsuccessful until now. The invention provides an electron beam flat display screen by adopting a new principle, and the CRT can be flatted and disclosed in a picture. The electron beam flat display screen has a different work principle with the CRT, the electron beam flat display screen adopts a refraction field to scan, the arc grating and the fan-shaped aberrance are revised by a special revising plate, the focus of the electron beams on a plane is solved by a zooming electron gun, the technology is simple, and the electron beam flat display screen can be colorized. Compared with the liquid crystal display and the plasma display, the electron beam flat display screen has ascendency, and the success of the electron beam flat display screen can lead the CRT to update.
Description
technical field [0001] The technical solution of the present invention relates to electronics and electronic information display technology Background technique [0002] In the information society, people obtain information mainly through vivid images, language, words and symbols. Therefore, the importance of information image display is becoming more and more prominent, and the quality requirements for image display devices are also getting higher and higher. It is for this reason that the research on high-quality display devices is getting hotter and hotter, making this field a booming field with strong vitality. [0003] In the field of display, in addition to the traditional cathode ray tube or CRT, many new devices have appeared in recent years. Mainly include: Liquid Crystal Display (LCD), Field Emission Display (FED), Plasma Display (PDP), etc. Among these displays, liquid crystal and plasma displays are already on the market, and field emission displays are still ...
