Abstract
The utility model provides a 16:9 wide screen thin type completely flat color kinescope which comprises a glass screen (1), a glass awl (2) and a pipe base (3). The glass awl (2) and the pipe base (3)are adapted with the glass screen (1). The height sum of the glass screen (1), the glass awl (2) and the pipe base (3) is within 313 to 326mm. Fluorescent powder in three base colors is coated on theinner surface of the glass screen (1) and is used for finishing conversion between electricity and light. Electric-conduction graphite coatings are coated on the inner and outer surfaces of the glassawl (2). The glass screen (1) and the glass awl (2) are connected by low melting glass in a sealing manner. An exhaust branch pipe which passes through a core column carries out air exhaust on the kinescope to finally form the kinescope with high vacuum degree. The pipe base (3) is sheathed on the core column of an electron gun. The color kinescope is 94.5mm thinner than the common kinescope, obviously improves the disadvantage that the common kinescope is thick and awkward, and realizes reduction of the entire thickness.
Description
Technical field
The utility model relates to a kind of color picture tube, and particularly a kind of face the ratio of width to height is the slim pure flat color picture tube of 16: 9 widescreen.
Background technology
Color picture tube is as the image display device of traditional color television set, and for a long time, advantage such as cheap with it, that image is vivid, color is true to nature gains great popularity in the numerous consumer groups.But along with developing rapidly of plate color television sets such as liquid crystal, plasma, the thick stupid problem of color picture tube has highlighted at present and has been a kind of defective by contrast; For this deficiency that makes the common color picture tube minimizes, in order to prolong the life cycle of CRT, the manufacturing firm of color picture tube makes great efforts to open up in the slimming direction, so occurred 4: 3 common ratio screen slimming CRT color television sets on the market in succession, but 16: 9 slim color picture tubes of widescreen do not occur as yet.Along with popularizing of digital television signal, began on the market in nearly 2 years to occur can with 16: 9 widescreen 61cmPF color television sets of digital television signal coupling, but its picture tube still belongs to general thickness in the past, and the nominal thickness size is 407.5～420.5mm, still exists thick stupid shortcoming.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of 16: the 9 slim pure flat color picture tubes of wide screen, and the homogeneous tube gauge is 313mm～326mm, than in the past common tube attenuate 94.5mm.
For achieving the above object, the technical solution adopted in the utility model is: a kind of 16: the 9 slim pure flat color picture tubes of wide screen, comprise glass screen 1 and suitable with it glass awl 2, pipe base 3, it is characterized in that the height sum of described glass screen 1 and glass awl 2 is between 295.2mm～308.2mm.
The height sum of described glass screen 1 and glass awl 2, pipe base 3 is between 313mm～326mm.
Because the utility model has shortened to 313mm～326mm from the common colored picture tube thickness of same size 407.5mm～420.5mm in the past, than in the past common tube attenuate 94.5mm, obviously improve the thick stupid defective of common color picture tube homogeneous tube in the past, realized the slimming of 16: 9 pure flat color picture tube integral thickness of widescreen.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to accompanying drawing, a kind of 16: the 9 slim pure flat color picture tubes of wide screen comprise glass screen 1 and suitable with it glass awl 2, pipe base 3, and the height of glass screen 1 is 74mm～78mm, the height of glass awl 2 is 218.5mm～230.2mm, makes the height sum of glass screen 1 and glass awl 2 at 295.2mm～308.2mm; Add the height 17.8mm of standard component pipe base 3, make glass screen 1 and glass bore 2, manage the height sum of base 3 between 313～326mm.
Operation principle: the inner surface of glass screen 1 is coated with three primary colors fluorescent powder, is used to finish the electrical-optical conversion; The surfaces externally and internally of glass awl 2 scribbles the electrically conductive graphite coating, and glass screen 1 is used frit seal between boring 2 with glass, and the exhaust branch pipe by stem stem finally forms a picture tube with condition of high vacuum degree to the picture tube exhaust.Pipe base 3 is enclosed within on the stem stem of electron gun.Because the glass bulb of color picture tube is operated in the environment of high vacuum, it must satisfy color picture tube to requirements such as light, electricity, heat, magnetic, stress, X ray, fail safes, also must satisfy in the color picture tube manufacture process requirement to the effect of various physics, machinery, chemistry.The utility model has not only satisfied the above-mentioned versatility requirement to glass bulb, and has realized good coupling with shadow mask, electron gun and deflecting coil, thereby has filled up the blank of the slim color picture tube of 61cm WPF.
Claims (2)
1, a kind of 16: 9 slim pure flat color picture tubes of wide screen comprise glass screen (1) and suitable with it glass awl (2), Guan Ji (3), it is characterized in that the height sum of described glass screen (1) and glass awl (2) is between 295.2mm～308.2mm.
2, a kind of 16: the 9 according to claim 1 slim pure flat color picture tubes of wide screen is characterized in that, the height sum of described glass screen (1) and glass awl (2), Guan Ji (3) is between 313～326mm.
