Abstract
The invention discloses a display device and particularly relates to a miniature CRT which is small in size and high in luminance and resolution. The miniature CRT comprises a fluorescent screen, a vacuum chamber, a deflection acceleration cavity and an electron emission gun, wherein the fluorescent screen, the vacuum chamber, the deflection acceleration cavity and the electron emission gun are arranged in sequence. The electron emission gun is composed of a cathode and a bulb adding electrode which are both connected with the deflection acceleration cavity, and an anode is connected to the vacuum chamber; the fluorescent screen is rectangular and is 110mm long and 85mm wide. According to the miniature CRT, because the electron emission gun is composed of the cathode and the bulb adding electrode which are both connected with the deflection acceleration cavity, the anode is connected to the vacuum chamber and the fluorescent screen is rectangular and is 110mm long and 85mm wide, and thus the whole miniature CRT has the advantages of being small in size, high in luminance and resolution and the like.
Description
Technical field
The present invention relates to display device, particularly little, the high brightness of a kind of volume, high-resolution miniature CRT.
Background technology
Display mainly contains liquid crystal display and CRT monitor, although liquid crystal display has the advantages such as energy consumption low distortion is low at present, in a lot of fields, still to use CRT, because the matching ratio of CRT color saturation, contrast, brightness is more perfect, response speed is exceedingly fast, long service life.It is exactly that volume is too large that yet CRT exists a larger shortcoming.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of volume is little, high brightness, high-resolution miniature CRT.
The present invention solves technical scheme that its technical problem adopts: miniature CRT, comprise the phosphor screen, vacuum chamber, deflection accelerating cavity and the electron emission rifle that set gradually, described electron emission chamber by the negative electrode being all connected with deflection accelerating cavity and add bubble the utmost point form, on described vacuum chamber, be connected with anode; Described phosphor screen is rectangle, long 110mm, wide 85mm.
Described phosphor screen adopts P53 fluorescent material.
The invention has the beneficial effects as follows: miniature CRT of the present invention, due to described electron emission chamber by the negative electrode being all connected with deflection accelerating cavity and add bubble the utmost point form, on described vacuum chamber, be connected with anode; Described phosphor screen is rectangle, long 110mm, and wide 85mm, makes whole miniature CRT have the features such as volume is little, high brightness, high-resolution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-phosphor screen, 2-vacuum chamber, 3-deflection accelerating cavity, 4-negative electrode, 5-add the bubble utmost point, 6-anode.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, miniature CRT of the present invention, comprise the phosphor screen 1, vacuum chamber 2, deflection accelerating cavity 3 and the electron emission rifle that set gradually, described electron emission chamber is by the negative electrode 4 being all connected with deflection accelerating cavity 3 and add the bubble utmost point 5 and form, and on described vacuum chamber 2, is connected with anode 6; Described phosphor screen 1 is rectangle, long 110mm, wide 85mm.Miniature CRT of the present invention, because described electron emission chamber is by the negative electrode 4 being all connected with deflection accelerating cavity 3 with add the bubble utmost point 5 and form, is connected with anode on described vacuum chamber 2; Described phosphor screen 1 is rectangle, long 110mm, and wide 85mm, makes whole miniature CRT have the features such as volume is little, high brightness, high-resolution.
Described phosphor screen 1 can adopt P1, P43 or other phosphor material powders, but these materials are easily aging, and useful life is low, for extending the useful life of phosphor screen 1, as preferred a kind of mode, is that described phosphor screen 1 adopts P53 fluorescent material.Such fluorescent material has advantages of that aging speed is slow, long service life.
