Description
Technical field
The present invention relates to screen printing net plate technical fields, more particularly to a kind of screen printing net plate and preparation method thereof.
Background technique
The existing common packaging method of display device is by the way of dispensing or silk-screen printing by sizing materials such as epoxy glues
It is coated on substrate or cover board, then the substrate for being formed with display device is bonded with cover board, then dried again, and then realize
The encapsulation of display device, it is still, slow using dispensing mode speed, and pressure for dispensing glue is not easy to control, be easy to cause disconnected glue or
Overbrushing, few gluing cause to encapsulate bad disadvantage.
As shown in Figure 1, it is the existing schematic diagram for being coated epoxy glue with plates for screen printing, the plates for screen printing
A pull spring net 1 ', adjacent two X-axis lines 11 ' and the formation of Y-axis line 12 ' are formed by several X-axis lines 11 ' and the tensioning of several Y-axis lines 12 '
One mesh, purpose is in varying numbers, determines with specific reference to required tension difference, will then according to the position of required coating epoxy glue
Coating covering is starched with nets such as glue in the position (area Fei Xiajiao 2 ') of unwanted coating epoxy glue, leaves behind and needs to be coated with epoxy glue
Partial silk screen (area Xia Jiao 3 ').Although this mode for carrying out epoxy glue coating with plates for screen printing improves to a certain extent
Application rate, but X-axis line 11 ' and the 12 ' place of intersecting of Y-axis line will form the cross i.e. net knot 13 ' of lamination, such as Fig. 2 institute
Show, height increases, and is formed a protrusion (even if the net knot for being located at the area Fei Xiajiao after covering glue still can be raised), flat with silk screen
There is difference in height in face, and when printing epoxy glue, it is out-of-date that scraper is scraped from network, and net knot 13 ' will increase the wind for weighing the film of the PI on substrate wounded
Danger, because PI material is thin very fragile (40 ~ 60nm), it is easy to be weighed wounded by the net knot 13 ' of silk screen, if being imprinted out in PI film surface
Dry net node (cross mark) not only influences beauty, but also is just easy to show mark when display, reduces the non-defective unit of production
Rate and display effect.
The prior art, which solves the scheme that net knot 13 ' weighs PI film wounded, mainly to be had: being increased web plate thickness and is netted slurry thickness, although slow
The case where net knot pressure hurts PI film is solved, but lower glue amount can increased significantly, and aperture position thickens web plate mainly close to web edge
Thickness is unfavorable for silk-screen；Also have by adjusting optimization silk screen printing process, but need largely to be tested and required operator
It is experienced, not only higher cost and for different structure frame need again re-optimization adjust so that technique become complexity,
It is difficult to unification, is unfavorable for improving production efficiency and product quality.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of production methods of screen printing net plate, in original silk printing screen
Add one layer of net slurry with padded again around lower glue position on the basis of plate, the area Ji Xiajiao has the screen printing net plate of difference in height with the area Fei Xiajiao,
So that the region of contact membranes especially PI film is hanging, pressure of the net knot on PI film is reduced, net knot pressure is avoided to hurt PI film, Bu Huiliu
Lower cross prints point, keeps beautiful；It is at low cost and without changing silk screen printing process, it is with good economic efficiency.
