Description
Technical field
The present invention relates to gas discharge technical fields, and in particular to a kind of electric machine structure of computer display.
Background technique
In recent years, in the market of television set, flat panel TV has become the mainstream in market instead of CRT.In plate electricity
Depending in, plasma display occupies one seat with its superior performance and lower price, with its light efficiency and service life
It improves and the reduction of energy consumption, plasma display has greatly the gesture for catching up with and surpassing LCD.
Plasma display is the cavity that several ordered arrangements are formed using the barrier of two pieces of glass substrates and centre, will
It is charged therein with the mixing rare gas centainly matched by the pressure of certain ratio, each group of show electrode and addressing electrode phase
It hands over, the corresponding cavity of each intersection point forms a discharge cell.Display is connected with driving circuit, is being shielded by electrode
Interior formation charge difference, so as to cause gas discharge, discharge gas generates ultraviolet light excitated fluorescent powder and issues visible light.
The good plasma display of sealing-in is using crystal grain mantle structure dress technology (abbreviation COF) or flexible print circuit
(FPC), it and with driving circuit connect, first in electrode connecting end hot pressing anisotropic conductive film (abbreviation ACF), then exists again
Hot pressing crystal grain mantle structure dress or flexible print circuit in anisotropic conductive film.Since current display largely uses
The structure of three electric pole types, so generally having three groups (X show electrode, Y show electrodes, addressing electrode) or four groups of (X display electricity
Pole, Y show electrode, addressing electrode upper and lower side), electrode tip needs to carry out hot press working.Thus workload is quite big, works
Period is long and the dosage of ACF and COF, FPC are big, at high cost.
According to the different characteristics of various electrodes, wherein the number of addressing electrode (abbreviation add) is most, and lines are most narrow, from
And need the quantity of COF to be used most, required precision highest；The quantity of show electrode is relatively fewer, and lines are also wider,
The quantity of FPC to use is also minimum.X show electrode and Y show electrode make a big difference again.Y show electrode is also known as
Scan electrode, relatively independent work between electrode and electrode；X show electrode also known as maintains electrode, and each electrode forms parallel connection, together
When work.
Based on above description, the hot press working of X show electrode in the prior art end is complex, materials'use ratio
Compared with waste, the contraposition process in hot pressing will cause product failure product a possibility that it is big.Also, it is easy to appear defective products,
When needing to remove anisotropic conductive film ACF, due to applying external force, electrode end is easily damaged, and easily causes electrode
Open circuit.
Summary of the invention
The technical problem to be solved by the present invention is to overcome drawbacks described above existing in the prior art, provide a kind of computer
The electric machine structure of display reduces X show electrode end heat pressing process effectively to simplify X show electrode end heat pressing process
Cost, and reduce the probability that defective products generates in the heat pressing process of X show electrode end.
To solve the above problems, the electric machine structure of computer display according to the present invention includes preceding substrate, wherein should
The X show electrode lead portion of preceding substrate includes: stripes, and X show electrode is connected to the stripes；And block portion, the block
The side in shape portion is connected with stripes, and the edge that the other side extends to display is connected with flexible printed circuit board.
Preferably, the width of stripes is 2-8mm.
Preferably, the width of block portion is 50-100mm.
Preferably, block portion is connected in the middle position of stripes with stripes.
Preferably, stripes and block portion are made of material identical as show electrode.
Preferably, stripes and block portion are made of Ag slurry.
The present invention has following technical effect that
The electric machine structure of computer display according to the present invention, due to using the structure for including strip structure and block structure
Body replaces multiple linear contact conductors in the prior art, the end of X show electrode is reduced to a structure, thus not
It reduced by only production cost, shorten the production technology period, moreover, fundamentally having prevented X show electrode in lead district
Electrode open circuit conditions, while damage to contact conductor when also having prevented to wipe ACF.
Detailed description of the invention
Attached drawing forms a part of this specification, for helping to further understand the utility model.These attached drawings illustrate
Some embodiments of the present invention, and can be used to illustrate the principle of the present invention together with specification.In attached drawing:
Fig. 1 schematically shows front base plate structure schematic diagram in the prior art；
Fig. 2 schematically shows the structural schematic diagrams of the front base plate structure of embodiment according to the present invention.
Specific embodiment
Below in conjunction with attached drawing, to the preferred embodiment of the electrode structure of plasma display according to the present invention do into
The detailed description of one step.
Fig. 1 schematically shows front base plate structure schematic diagram in the prior art, is provided with show electrode on substrate 11
14, and it is respectively provided with x show electrode lead portion 16 and y show electrode 15, transparent dielectric layer is covered on show electrode 14
12 and protective film 13.
Fig. 2 schematically shows front base plate structure schematic diagrames according to the present invention.In the preferred embodiment of the present invention
In, it is provided with show electrode 24 on substrate 21, transparent dielectric layer 22 and protective film 23 are covered on show electrode 24.With Fig. 1
Unlike, X in Fig. 1 is substituted with strip structure (or stripes) 26 and block structure (or block portion) 27 in Fig. 2 and shows
Electrode lead portion 16.As shown in Fig. 2, strip structure 26 and all 24 phases of X show electrode positioned at X show electrode edge
Connection, the other side of the strip structure 26 are connected with a block structure 27, and the other side of the block structure 27 extends to display
The edge of device is connected with flexible print circuit.
The width of strip structure 26 is 2-5mm, and longitudinally through display panel.Draw on 26 middle position of strip structure
Block structure 27 extends to the edge (as shown in Fig. 2) of display screen out, and the width of the block structure is 50-100mm.
Strip structure 26 and block structure 27 use Ag slurry identical with show electrode, and can use printing technology
Production, furtherly, strip structure 26 and block structure 27 can make simultaneously with bus electrode 25.
Since strip structure of the invention and block structure are instead of the linear of lead district in the prior art, thus
X reality electrode is fundamentally prevented in the electrode open circuit conditions of lead district, while also having prevented to draw electrode when erasing ACF
The damage of line.Meanwhile by the way that terminals are reduced to one, means of production cost is reduced, the production technology period is shortened.
The above is only a preferred embodiment of the present invention, is not intended to limit the utility model, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification for being made all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
