Description
Technical field
The utility model relate to screen printing net plate technical field, more particularly to a kind of screen printing net plate.
Background technology
The conventional method for packing of existing display device is by sizing materials such as epoxy glues by the way of dispensing or serigraphy
It is coated on substrate or cover plate, then the substrate for being formed with display device is fitted with cover plate, then dried again, and then realizes
The encapsulation of display device, but, it is slow using dispensing mode speed, and pressure for dispensing glue is wayward, easily cause disconnected glue or
Overbrushing, few gluing cause to encapsulate bad shortcoming.
As shown in figure 1, it is the schematic diagram that existing plates for screen printing is coated epoxy glue, the plates for screen printing
One pull spring net 1 ' is formed by several X-axis lines 11 ' and the tensioning of several Y-axis lines 12 ', adjacent two X-axis lines 11 ' and Y-axis line 12 ' are formed
One mesh, purpose quantity is determined with specific reference to required tension force is different, then according to the position of required coating epoxy glue, will
The position of unwanted coating epoxy glue（Fei Xiajiao areas 2 '）Covered with the net slurry coating such as glue, leaving behind needs to be coated with epoxy glue
Partial silk screen（Xia Jiao areas 3 '）.Although this mode for carrying out epoxy glue coating with plates for screen printing is improved to a certain extent
Application rate, but X-axis line 11 ' and the Y-axis line 12 ' place of intersecting can form the cross i.e. net knot 13 ' of lamination, such as Fig. 2 institutes
Show, height increases, form a projection（Even if the net knot covered after glue positioned at Fei Xiajiao areas still can be raised）, it is flat with silk screen
There is difference in height in face, and when epoxy glue is printed, it is out-of-date that scraper is scraped from network, and net knot 13 ' can increase the wind of the PI films weighed wounded on substrate
Danger, because PI materials are thin very fragile（40~60nm）, it is easy to weighed wounded by the net knot 13 ' of silk screen, if going out in PI film surface imprints
Dry net node（Cross impression）, just it is easy to show impression when not only affecting attractive in appearance, and showing, reduce the non-defective unit of production
Rate and display effect.
Prior art solves net ties the 13 ' schemes for weighing PI films wounded mainly has：Increase web plate thickness and net slurry thickness, although be slow
The situation that net knot pressure hinders PI films, but lower glue amount meeting showed increased have been solved, and aperture position thickens web plate mainly close to web edge
Thickness is unfavorable for silk-screen；Also have by adjusting and optimizing silk screen printing process, but need to carry out substantial amounts of test and require operating personnel
It is experienced, not only relatively costly and for different structure frame need again re-optimization adjust cause technique become complexity,
It is difficult to unify, is unfavorable for improving production efficiency and product quality.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of screen printing net plate, its base in original screen printing net plate
