Description

A kind of wire mark plate for coated glass glue

Technical field

The utility model relates to OLED laser package technical field more particularly to a kind of wire marks for coated glass glue Plate.

Background technique

OLED, also known as Organic Electricity laser display, organic luminous semiconductor.OLED display technology has self luminous spy Property, the very thin coating of organic material of use and glass substrate, when a current passes through, these organic materials will shine, and And OLED display screen visible angle is big, and can save electric energy.

At present in the laser package manufacturing process in the field OLED, usual coated glass glue is carried out in a manner of wire mark. As shown in Figure 1, it shows the hardened structure of existing wire mark, the wire mark plate using this structure is carrying out glass cement encapsulation smearing When, the reason of because of glass cement itself by gravity, it is very easy to collapse after framework smears glass cement, especially middle part partial volume Shape of a saddle recess is easily formed, then such undesirable condition when carrying out subsequent encapsulation pressing and laser sintered (Lasersealing) The leakproofness for carrying out laser package to OLED will be directly influenced, and then occurred in water/oxygen invasion OLED element, water/oxygen with Electrode reaction in OLED element influences the service life of OLED element.

Summary of the invention

For this reason, it may be necessary to a kind of wire mark plate for coated glass glue be provided, to solve packaging technology processing procedure in the prior art The problem of middle glue surface flatness is bad, and causes OLED leakproofness bad, and OLED element electrode life is easy to cause to shorten.

To achieve the above object, a kind of wire mark plate for coated glass glue is inventor provided, the wire mark plate includes Wire mark plate framework, the wire mark plate framework are the ring structure of middle part hollow out, are equipped at least two phases in the wire mark plate framework The annular groove being mutually arranged, the groove width of the annular groove are 100-200 microns.

As a kind of preferred structure of the utility model, the wire mark plate is in square ring or circular ring structure.

As a kind of preferred structure of the utility model, all had down in the outer corners of the wire mark plate framework of square ring structure Angle.

As a kind of preferred structure of the utility model, the annular groove is 3.

As a kind of preferred structure of the utility model, the groove width of the annular groove is 150 microns.

It is different from the prior art, above-mentioned technical proposal has the advantages that the utility model one kind for coated glass glue Wire mark plate and will be annular by being equipped at least two annular grooves being mutually arranged in the wire mark plate framework of middle part hollow out The groove width of slot is limited between 100-200 microns, using the wire mark plate of this structure when carrying out glass cement encapsulation smearing, at least Glass cement is laid in two annular grooves, does not reduce the usage amount of glass cement generally, to guarantee preferable packaging effect, and can To form at least two layers of sealant, prevent water oxygen from entering, leakproofness is improved, while being coated with the width limit of single-glass glue Fixed the middle section of the wide smaller glass cement of glue not will form recess, and glue surface flatness is higher between 100 to 200 microns, sealing Property only to improve, water/oxygen can not intrude into OLED element and and electrode reaction, and then improve OLED element electrode and use the longevity Life.

Specific embodiment

Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality It applies example and attached drawing is cooperated to be explained in detail.

1 and Fig. 2 are please referred to, the utility model provides a kind of wire mark plate for coated glass glue, the wire mark plate 100 Including wire mark plate framework 200, the wire mark plate framework 200 is the ring structure of middle part hollow out, is set in the wire mark plate framework 200 There are at least two annular grooves 300 being mutually arranged, the groove width of the annular groove 300 is 100-200 microns.It is described in the utility model The wire mark plate for coated glass glue, it is placed on the glass substrate for being coated with circuit in actual use, by wire mark Glass cement is smeared in plate 100, and then lower layer is coated with to glass plate and the sealed connection of upper layer packaged glass plate of circuit, so that being located at Intermediate OLED element has good leakproofness, therefore in the present embodiment, and wire mark plate 100 is arranged to the annular of middle part hollow out Structure, middle part hollowed out area for being easy OLED element when in use.Existing wire mark plate 100 is carrying out glass cement encapsulation smearing When, the reason of because of glass cement itself by gravity, when the width that glass cement is smeared is excessive, be easy to sink in the middle part of glass cement to Shape of a saddle recess is formed, influences to seal effect, therefore the present embodiment will be equipped at least two in wire mark plate framework 200 and mutually be arranged Annular groove 300, and by the groove width of the annular groove 300 be 100-200 microns, annular groove is separated by muti-piece annular slab, It can be fixed by adhesion between adjacent annular plate and between annular slab and wire mark plate or connecting plate is connected and fixed.Using this The wire mark plate 100 of structure lays glass cement at least two annular grooves 300, generally when carrying out glass cement encapsulation smearing The usage amount of glass cement is not reduced, to guarantee preferable packaging effect, and can be formed at least two layers of sealant, be prevented water Oxygen enters, and leakproofness is improved, while the width for being coated with single-glass glue is limited between 100 to 200 microns, and glue is wide smaller The middle section of glass cement not will form recess, and glue surface flatness is higher, and only to improve, water/oxygen can not intrude into leakproofness In OLED element and and electrode reaction, and then improve OLED element electrode life.

Since in actual production process, the shape of this body structure of OLED element is not identical, corresponding glass substrate The difference of shape, the wire mark frame are needed according to the practical change carried out in shape, preferred embodiment, the wire mark plate 100 in square ring or circular ring structure, is also possible to other shapes in certain other embodiments certainly.As shown in Fig. 2, mesh Before, in actual fabrication, the shape of wire mark frame is still more with side's ring-type.

In order to remove the burr generated on wire mark plate 100 by machining, incised wound user is prevented, is caused using upper not side Just.Meanwhile in order to enable wire mark plate 100 more beautiful, the preferred wire mark plate in square ring structure in the particular embodiment The outer corners of frame 200 all have chamfering.Certainly, the angular dimension of the chamfering needs the wire mark plate framework according to square ring structure 200 size carries out corresponding adaptation setting.

As shown in Fig. 2, the annular groove 300 is 3 as in a kind of preferred embodiment of the utility model.Specifically, The groove width of the annular groove 300 is 150 microns.Set 3 for annular groove 300 in the present embodiment so that OLED element into Row three-layer protection, have been able to guarantee OLED element leakproofness, annular groove 300 it is more, undoubtedly will increase glass cement Coating it is time-consuming, and be 150 microns by the width of annular groove 300, can preferably prevent from being formed in each annular groove 300 recessed It falls into, so that glass cement face has preferable flatness, good airproof performance.

It should be noted that being not intended to limit although the various embodiments described above have been described herein The scope of patent protection of the utility model.Therefore, based on the innovative idea of the utility model, embodiment described herein is carried out Change and modification or equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly Or above technical scheme is used in other related technical areas indirectly, it is included in the protection model of the utility model patent Within enclosing.
