Abstract
A miniature display mainly includes glass shell, electron gun, deflection coil, magnetic shield. Electronic gun is in glass shell, and glass shell has deflection coil, the most outer being magnetic shield. The glass shell is the cylindrical depressed with the first half, from which leads HV lead. The electronic gun is the two crossing-flow large-caliber electric gun, including the core column, cathode component, modulation pole, speed up pole, focused pole and the anode coated inside the glass shell in turn. In the focused pole installed the two restricted flow membrane pore. This invention has the characteristics of small size, light weight, and high resolution, and it can be applied to the terminal display of modern high requirements.
Description
Technical field the invention belongs to the electric vacuum display device field, particularly a kind of high resolution micro display.
Background technology is present, and in the civilian miniature display tube, brightness and resolution are all generally lower, and volume is bigger than normal, and weight lays particular stress on, and can't be applied in the micro terminal display of modern high request.In order to follow the tracks of external advanced level, for good demonstration change system is provided, it is as one of critical component of display system.
Summary of the invention is in order to overcome in the existing miniature display tube, and brightness and resolution are all generally lower, and volume is bigger than normal, and the weak point that weight lays particular stress on the invention provides a kind of miniscope that volume is little, in light weight, resolution is high that has.
The technical solution adopted for the present invention to solve the technical problems is: a kind of miniscope mainly is made of glass bulb, electron gun, deflecting coil, magnetic shielding cover.Electron gun is provided with deflecting coil on the glass bulb in glass bulb, outermost layer is a magnetic shielding cover.Described glass bulb is the cylindricality of first half depression, therefrom draws high-voltage connection, and deflecting coil is installed in the glass bulb depressed part.Front end is a phosphor screen, and the rear end is the stem stem of electron gun.Described electron gun is two heavy caliber electron guns that dam, and is made of successively stem stem, cathode assembly, Wehnelt electrode, intensifying ring, focusing electrode and the coated anode at the glass bulb inwall.Two current limliting fenestras are set in focusing electrode.Each grid is fixed by glass supporter, is provided with two claw type supports before and after also at the electron gun inner assembly, and the spring leaf of symmetric arrangement is arranged on two claw type double brackets, relies on shell fragment self elastic force to be fastened on the glass bulb internal diameter.Between two supports, be provided with biconjugate face getter.
Described magnetic shielding cover is selected the high magnetic conduction soft magnetic material of 1J79, makes the radome that wall thickness is 0.3-0.7mm.Described claw type support is respectively four paws, six pawls.Described deflecting coil is the inserted deflecting coil of tile.Described phosphor screen is the optical fiber fluorescent display screen.Described high-voltage connection is plating magnesium silk.
The claimed technical scheme of the application has been discarded traditional glass bulb anode button, replaces with plating magnesium silk high-voltage connection, and in the middle of high-voltage connection guided to glass-tube from traditional glass awl.The first half of glass bulb adopts recessed formula, has discarded traditional straight barrel type, when after loading onto the tile type coil on the concave surface, will be concordant with the latter half, and like this, glass bulb just can not be because of being straight barrel type and make volumetric expansion after loading onto deflecting coil and cause volume bigger than normal.Because be the high-voltage connection formula, not only dwindled the sectional area of high-pressure section, and directly avoided high pressure to run into deflecting coil and cause high voltage flash.Therefore this glass bulb has solved the problem that volume is bigger than normal, weight lays particular stress on very practically.
Electron gun in the claimed technical scheme of the application has used two heavy caliber electron guns that dam, and has four glass support framves and two current limliting fenestras in the electron gun.Taking of these measures, just the definition of miniature display tube is greatly improved.Adopted two supports that have spring leaf in the rifle, be inserted in caliber after, rely on spring leaf self elastic force to be fastened on the caliber, between support, adopted biconjugate face getter.The employing of these measures significantly improves the reliability of miniature display tube, has satisfied the needs of display tube.
The invention has the beneficial effects as follows, adopt depression shape glass bulb, being convenient to deflecting coil places, reduce volume effectively, adopt two heavy caliber electron gun and optical fiber phosphor screens of damming to improve monitor resolution effectively, each parts of electron gun are fastening by each bracing frame, and the reliability of display tube is increased substantially.Resolution surpasses the 0.025mm live width, reaches the every technical parameter of display tube assembly and the test requirements document of regulation comprehensively.
