A kind of display floater method for packing and display floater
Technical field
The present invention relates to display floater making technology, more particularly, to a kind of increase packaging plastic tack
Display floater method for packing and display floater.
Background technology
Existing display floater mainly includes laying the viewing area of pixel, and around viewing area
Packaging area.At present, as Fig. 1, display floater 10 ' encapsulation generally adopts packaging plastic 6 ' (frit
Glue) along the packaging area coating around viewing area 8 ', by component package substrate and cover plate it
Between, main inclusion packaging plastic dispensing area 9 ' in packaging area.And, packaging plastic is directly and substrate
When contacting with cover plate, tack is the strongest, but because display floater technique becomes increasingly complex, the number of plies increases
Many, in some cases, packaging plastic can not directly contact substrate (or cover plate), then can weaken attachment
Property, reduce intensity and physical stress of display floater itself etc..
As shown in Fig. 2 a kind of existing display floater method for packing, comprise the following steps:
S201: in a substrate 1 ' upper deposition one cushion 2 ' (buffer layer), by mask artwork
After case and etching technics, form cushion 2 ' in packaging plastic dispensing area.
S202: deposit a gate insulator 3 ' (gi layer) and grid on described cushion 2 '
Pole metal conducting layer 4 ' (gl layer), after mask patterning and etching technics, in packaging plastic
Dispensing area forms grid-shaped metal conductive layer.
S203: in the upper deposition of described gate metal conductive layer 4 ' (gl layer) conducting insulating barrier 5 '
(ct layer), after mask patterning and etching technics, forms grid in packaging plastic dispensing area
Shape interlayer insulating film.
S204: in described conducting insulating barrier 5 ' (ct layer) upper deposition one source-drain electrode metal conducting layer
(dl layer, in figure is not shown), after mask patterning and etching technics, packaging plastic applying area
Domain passive drain electrode metal conducting layer covers.
S205: in described source-drain electrode metal conducting layer (dl layer) upper coating one layer of planarization layer (figure
Not shown in), after mask patterning and etching technics, packaging plastic dispensing area no planarization layer
Cover.Planarization layer is predominantly located at viewing area, and the main purpose of planarization layer is to eliminate lower floor's figure
The pixel light emission area out-of-flatness that the offset of shape causes.
S206: an anode metal layer (not shown) is deposited on described planarization layer, passes through
After mask patterning and etching technics, packaging plastic dispensing area no anode metal layer covers.
S207: a pixel defining layer (not shown) is coated with described anode metal layer, leads to
After crossing mask patterning and etching technics, packaging plastic dispensing area no pixel defining layer covers.
S208: in viewing area, in described pixel defining layer evaporation Organic Light Emitting Diode layer with
Cathode layer (not shown).
S209: filling packaging plastic, cover plate 7 ' of fitting.As shown in Fig. 3 (a) and 3 (b), such as
Filling packaging plastic 6 ' touches backboard come cover plate 7 ' of fitting, then packaging plastic 6 ' to fruit in this case
Be cushion 2 ', the tack between packaging plastic 6 ' and substrate 1 ' is weaker.For the ease of right
3 (a), 5 (a) in this case is all identical with packaging plastic dispensing area 9 ' with 7 (a) for ratio
Region a is amplification subject, and here is omitted.
In order to expose substrate 1 ', existing improved method is to increase a mask and one work
Skill, with continued reference to Fig. 4, comprises the following steps:

(ct layer), after mask patterning and etching technics, forms grid in packaging plastic dispensing area
Shape interlayer insulating film.
S304: in described conducting insulating barrier 5 ' (ct layer) upper deposition one source-drain electrode metal conducting layer
(dl layer, in figure is not shown), after mask patterning and etching technics, packaging plastic applying area
Domain passive drain electrode metal conducting layer covers.
S305: in described source-drain electrode metal conducting layer (dl layer) upper coating one layer of planarization layer (figure
Not shown in), after mask patterning and etching technics, packaging plastic dispensing area no planarization layer
Cover.Planarization layer is predominantly located at viewing area, and the main purpose of planarization layer is to eliminate lower floor's figure
The pixel light emission area out-of-flatness that the offset of shape causes.(the step s301 to s305 in Fig. 4 with
Step s201 to s205 in Fig. 2 is identical.)
S306: increase by a mask plate, after mask patterning and etching technics, remove and expose to the open air
The cushion 2 ' of packaging plastic dispensing area, exposes described substrate 1 '.Portion of buffer layer 2 ' is moved
Except exposing substrate 1 ', also can remove the conducting insulating barrier 5 ' of part simultaneously.
S307: an anode metal layer (not shown) is deposited on described planarization layer, passes through
After mask patterning and etching technics, packaging plastic dispensing area no anode metal layer covers.
S308: a pixel defining layer (not shown) is coated with described anode metal layer, leads to
After crossing mask patterning and etching technics, packaging plastic dispensing area no pixel defining layer covers.
S309: in viewing area, in described pixel defining layer evaporation Organic Light Emitting Diode layer with
Cathode layer (not shown).
S310: filling packaging plastic, cover plate 7 ' of fitting.As shown in Fig. 5 (a) and 5 (b), will
After cover plate 7 ' laminating, packaging plastic 6 ' what packaging plastic dispensing area touched backboard is and packaging plastic
The substrate 1 ' (glass) of 6 ' same natures.Although this method can make packaging plastic 6 ' and substrate 1 '
Between tack increase, but due to need to increased mask with together with gold-tinted technique to remove slow
Rush layer 2 ', increased cost.
In view of this, a kind of display floater method for packing and display floater are inventor provided.
