The present embodiment provides a kind of organic electroluminescence display panel, as shown in Figure 1, it is had by what the embodiment of the present invention provided A kind of structure diagram of machine light emitting display panel, the organic electroluminescence display panel 500 include first substrate 1 and first substrate 1 The second substrate 2 being oppositely arranged, and the packaging plastic 3 for first substrate 1 and second substrate 2 to be bonded together, it is inevitable, should Packaging plastic 3 is arranged between first substrate 1 and second substrate 2.
Wherein, as shown in Fig. 2, it is provided a kind of structure diagram of first substrate by the embodiment of the present invention, this first Substrate 1 includes display area 10 and the packaging area 30 around display area 10, and packaging area 30 is arranged on the side of first substrate 1 Frame surrounding.Packaging plastic 3 is located at packaging area 30 in the orthographic projection of first substrate 1 in the orthographic projection of first substrate 1, that is, Say, on first direction shown by Fig. 2 100, the maximum of the width of orthographic projection on first substrate 1 of packaging plastic 3 is encapsulation region The width b in domain 30.
With continued reference to Fig. 2, which further includes more signal lines 4, and packaging area 30 includes first area 301; In first area 301, the orthographic projection of at least partly more signal lines 4 on first substrate 1 is with least part packaging plastic 3 first Orthographic projection on substrate 1 overlaps.Packaging area 30 can be interpreted as to the region that packaging plastic 3 is covered in the present embodiment, that is, The region that the orthographic projection of packaging plastic 3 on first substrate 1 is covered.At this time, " in first area 301, at least partly a plurality of letter Number orthographic projection of line 4 on first substrate 1 is overlapped with the orthographic projection of at least part packaging plastic 3 on first substrate 1 ", at least may be used Understand that the signal wire 4 is arranged in the first area 301 of packaging area 30, further there is the following two kinds understanding:
The first, as described in Figure 3, the profile of AA ' positions, a plurality of letter in its Fig. 2 provided by the embodiment of the present invention The signal wire 4 of partial amt in number line 4 is arranged in first area 301.Signal wire 4 is also possible to be arranged in packaging area 30 The region outside first area 301 is removed, but this example is not particularly limited it.The present embodiment is due to by more bars The signal wire 4 of a part of quantity in line 4 is arranged in packaging area 30, can reduce routing region (explain in detail and see below) width Degree, and then reduce the border width of whole organic electroluminescence display panel 500.
Second, as shown in Figure 4 and Figure 5, Fig. 4 is shown by another structure for the first substrate that the embodiment of the present invention provides It is intended to, the profile of BB ' positions, the part of of signal wire 4 itself are arranged in Fig. 4 that Fig. 5 is provided by the embodiment of the present invention In first area 301.It is relatively reduced since by signal wire 4, the part of itself is arranged in first area 301 (packaging area) Signal wire 4 accounts for the width of routing region (as detailed below), and the frame that can significantly reduce organic electroluminescence display panel 500 is wide Degree.
Certainly, more signal lines 4 are may also comprise in display area 10, not to being arranged on display area 10 in the present embodiment Place film layer, quantity and the width of signal wire 4 etc. make and being particularly limited to.
Light-emitting component in organic electroluminescence display panel is prepared by organic material, although its have actively shine, The advantages such as contrast is higher, but the organic material in light-emitting component easily receives the intrusion of aqueous vapor and oxygen so that this shines Aging and denaturation occur for element, so as to influence brightness and the service life of the light-emitting component.
It is to solve the above-mentioned problems, it is necessary to hermetically sealed to organic electroluminescence display panel progress, using molten in the present embodiment Packaging technology is connect, i.e., packaging plastic 3 is heated using laser spot, it is molten into liquid, by the frame of first substrate 1 and The frame of two substrates 2 is bonded together so that forms closed area between first substrate 1 and second substrate 2, obstructs the water in the external world Invaded with oxygen from the side of the organic electroluminescence display panel 500, further prevent the hair in the organic electroluminescence display panel 500 Optical element contacts water and oxygen.Packaging plastic 3 in the present embodiment can be glass cement (Frit) material, be inhaled in this kind of material containing laser The property received pigment, it is changed into molten condition after absorbing light, so as to can reach good adhesive effect, sealing effect is preferable.
In order to make the packaging plastic absorb more light, the present embodiment sets at least partly a plurality of letter in first area 301 Number line 4, the orthographic projection of at least partly more signal lines 4 on first substrate 1 with least part packaging plastic 3 on first substrate 1 Orthographic projection overlap, that is to say, that the more signal lines 4 of at least part are arranged in first area 301, and due to firstth area Domain 301 is a part for packaging area 30, it will thus be appreciated that the signal wire is arranged in packaging area 30.Due to the signal wire 4 material can be metal, and exemplary is metal molybdenum so that the signal wire 4 can reflection laser spot, by the laser spot of reflection again Secondary irradiation packaging plastic 3, improves irradiation temperature, promotes packaging plastic 3 to the absorbability of laser, reaches preferably fusing effect.
Organic electroluminescence display panel of the prior art includes display area, the routing region of display area periphery, and walks Line region all around around packaging area.The orthographic projection of the routing region on the first substrate and packaging area are on the first substrate Orthographic projection no overlap, that is to say, that the routing region and the packaging area around the routing region constitute organic light emission and show Show the non-display area in panel.More signal lines of the prior art are arranged in the routing region on the outside of display area.Mesh Before, with the gradual increase of display screen, the signal wire in scanning circuit is that quantity is consequently increased.However, corresponding specific ruler For very little organic electroluminescence display panel, the quantity of signal wire increases, and will certainly increase the width of routing region, so that accordingly The width of display area reduces.Furthermore border width increases, and is also disagreed with present fashion trend.
In the present embodiment, in first area 301, at least partly more signal lines 4, at least partly more signal lines are set 4 orthographic projection on first substrate 1 is overlapped with least part 3 orthographic projection on first substrate 1 of packaging plastic, that is to say, that should At least partly more signal lines 4 are arranged in first area 301, and since the first area 301 is one of packaging area 30 Point, it will thus be appreciated that at least part signal wire is arranged in packaging area 30.For the signal wire of equivalent amount, this reality Applying in example can be arranged on the signal wire of partial amt in packaging area, so as to reduce the width of routing region;Alternatively, for For the signal wire of commensurateiy wide, the part of signal wire in itself can be arranged in the present embodiment in packaging area, and then subtract The small signal wire takes the width of routing region.The frame that above two mode can reduce organic electroluminescence display panel is wide Degree, increases the width of display area in the organic electroluminescence display panel accordingly.For compared with the prior art, the present embodiment The border width of organic electroluminescence display panel can effectively be reduced, beneficial to the realization of narrow frame.
In a kind of feasible embodiment, as shown in fig. 6, its organic light emitting display for being provided by the embodiment of the present invention Another structure diagram of panel, the organic electroluminescence display panel 500 further include area of isolation 20, and area of isolation 20 is arranged on Between packaging area 30 and display area 10, from packaging area 30 to the direction of display area 10 on, direction as illustrated in FIG. 6 On 100, the width y of area of isolation is 45~55 millimeters.Cabling is also provided between display area 10 and area of isolation 20 Region 60, scanning element 9 can be set in the routing region 60, can be included and at least partly heated easily be burnt in scanning element 9 Device, the setting of area of isolation 20 is to protect device in routing region 60, avoid device from being heated and burn in the present embodiment. This is because in encapsulation process, the temperature of laser spot is higher, so as to can be heated and burn in encapsulation process there are device Situation.How to select the scope of the area of isolation, be a technological difficulties, inventor by test of many times, repeatedly conscientious grind Show that the width of the area of isolation 20 is arranged between 45~55 millimeters after studying carefully, optionally, this can be isolated in the present embodiment The width in region 20 is arranged to 50 millimeters.When the width of area of isolation 20 is less than 45 millimeters, the device that is arranged in routing region 60 Part distance packaged region 30 is relatively near easily heated and damages;When the width of area of isolation 20 is more than 55 millimeters, although routing region 60 Interior device is not easy to be excited the influence of hot spot, and still, the width increase of area of isolation 20, it is narrow to be unfavorable for organic electroluminescence display panel The realization of frame, is disagreed with fashion trend.For the organic electroluminescence display panel of specific dimensions, the width of area of isolation It is larger, then mean that the big width in display area is relatively small, be unfavorable for the realization of narrow frame.
It should be noted that the area of isolation 20 is only in the device for needing and being easily affected by temperature, there are ability during certain distance It can set;If device and/or cabling (signal wire) high temperature resistant, when laser spot does not influence it significantly, can be not provided with this every From region 20.
In a kind of feasible embodiment, as shown in fig. 7, its first substrate provided by the embodiment of the present invention is another A kind of structure diagram, the packaging area 30 are first area 301.Embodiment with reference to shown in above-mentioned Fig. 2 and Fig. 4 can Know, at least part signal wire 4 may be provided in the first area 301, at this time it is understood that in the present embodiment at least partly More signal lines 4 are arranged in whole packaging area 30, i.e., relatively greater number of signal wire 4 is arranged in packaging area 30. Greater number of signal wire 4 is arranged in packaging area 30, can be reduced the width of routing region, be reduced organic light emitting display The border width of panel 500.Simultaneously as the material of the signal wire is metal molybdenum, in encapsulation process, more laser are reflected Spot, and then preferable packaging effect.
In one embodiment, as shown in figure 8, another knot of its first substrate provided by the embodiment of the present invention Structure schematic diagram, the display area 10 include:First display area 101 and at least two second display areas 102, two second aobvious Show that region 102 is located at the same side of the first display area 101, and there is first area between two the second display areas 102 301.With reference to the embodiment of above-mentioned Fig. 2 and Fig. 4, in the present embodiment, which can be arranged in the first area 301, That is, the signal wire 4 sets the indentation, there of the organic electroluminescence display panel, the area between two the second display areas 102 Domain can be regarded as the gap regions of the organic electroluminescence display panel.It should be noted that in other implementations, the first display The quantity of 101 and second display area 102 of region can be multiple, and the quantity of gap regions can also be multiple, the application couple This is not specifically limited.
In another embodiment, as shown in figure 9, its organic electroluminescence display panel for being provided by the embodiment of the present invention Another structure diagram, organic electroluminescence display panel 500 it is two neighboring between by connecting while 501 connect, connect The shape on side 501 is can be arc illustrated in fig. 9, or the shape on the connection side can also be straight line, 4 company of being arranged on of signal wire In first area 301 at edge fit 501.
In one embodiment, as shown in Figure 10 and Figure 11, the first substrate that Figure 10 is provided by the embodiment of the present invention Another structure diagram, the profile of CC ' positions, the first substrate in Figure 10 that Figure 11 is provided by the embodiment of the present invention 1 further includes the package metals layer 5 positioned at packaging area 30, the orthographic projection of package metals layer 5 on first substrate 1 and signal wire 4 Orthographic projection no overlap on first substrate 1, that is to say, that be separated from each other, do not have between package metals layer 5 and the signal wire 4 There is a situation where contact, covering.For 4 position of signal wire, it can be opposite for the position of the package metals layer 5 Closer to display area, or it can be relatively distant from display area.In the present embodiment, since the signal of signal wire 4 needs to transmit Into display area 10 in corresponding circuit, therefore, it is remote that the package metals layer 5 in the present embodiment is arranged on more signal lines 4 The side of display area 10, as shown in Figure 8 and Figure 9.Those skilled in that art are it should be understood that in some realization sides of the application In formula, the package metals layer and signal wire that are arranged in first area all play reflection laser so as to strengthen the work of packaging effect With.In the first region in the case of presence signal line, encapsulation gold can not set by the region of signal wire covering in the region Belong to layer 5, and cause the package metals layer 5 and neighbouring signal wire insulation or in electrical contact.Therefore the embodiment of the present application for Package metals layer 5 is arranged at signal wire 4 and is relatively distant from display area closer to display area, or signal wire 4 and does not limit specifically It is fixed, depending on being needed with specific reference to actual design.
It should be noted that the material of the package metals layer 5 in the present embodiment is metal, exemplary is metal molybdenum, It is reflective it acts as in encapsulation process, being carried out to laser spot, and the laser spot of reflection is irradiated on packaging plastic again so that Packaging plastic preferably melts, so as to preferably bond first substrate and second substrate.It is also, glutinous after being melted due to the packaging plastic Degree is higher, after cooling cures, can produce certain stress, in order to which the stress release is fallen, in order to avoid influence sealing performance, this reality Apply in example and the package metals layer is arranged to engraved structure, so that after the encapsulation adhesive curing, should by the stomata of the hollow out Power discharges, and reaches good packaging effect.
In addition, package metals layer and signal wire can be located at different film layers, identical film layer may also be at, it is excellent in this example Choosing, package metals layer is located at same layer with film layer where signal wire.On the one hand can reduce by a step prepares signal for such setting The step of line or package metals layer, on the other hand in encapsulation process, distance and package metals of the signal wire apart from laser spot Layer is identical apart from the distance of laser spot so that the amount of laser light reflected in packaging area at each position is balanced, easy to obtain compared with Good packaging effect.
Further, as shown in figure 12, another structural representation of its first substrate provided by the embodiment of the present invention Figure, inventor narrow frame and packaging effect in order to balance, have carried out the width of the package metals layer in packaging area deep Research, draws after multiple data verification, from packaging area 30 to the direction 100 of display area 10, the width of package metals layer 5 To spend for a, the width of packaging area 30 is b, wherein, b/2≤a≤3b/4.Specifically, the width of package metals layer 5 is less than encapsulation During the half of the width b in region 30, its packaging effect is poor, it is to be understood that the amount of the laser spot of package metals layer reflection It is smaller, so as to extend the usage time of laser spot, the light-emitting component in display area may be impacted;Package metals layer After 5 width is smaller, the stress that is also unfavorable for after release encapsulation adhesive curing influences packaging effect.The width of package metals layer is too Greatly, after 3/4ths of the width of packaging area 30, although packaging effect is preferable, remaining width is smaller, is unfavorable for Setting signal line, further, even if being provided with signal wire on remaining a quarter width, its border width reduced It is very limited.The present embodiment is preferable, and the width a of the package metals layer is about 5/8ths of packaging area width.
With continued reference to Figure 10, from packaging area 30 to the direction 100 of display area 10, the width c of signal wire 4 for 20~ 30 microns.How to determine the width of signal wire is a technological difficulties, and signal wire is too wide to influence organic electroluminescence display panel Border width, signal wire is too narrow and signal transmission can be impacted.Inventor show that signal wire 4 exists after deeply studying intensively From packaging area 30 to the direction 100 of display area 10, its width is 20~30 microns.This is because signal wire 4 is square herein After being less than 20 microns to the width on 100, the resistance of signal wire 4 is relatively large, and the transmission to signal causes larger obstruction.Letter After number width of the line 4 on above-mentioned direction 100 is more than 30 microns, although beneficial to the transmission of signal, organic light emission can be shown Show that the border width of panel broadens, be unfavorable for the realization of narrow frame.This example is preferable, and the signal wire 4 is on above-mentioned direction 100 Width be 25 microns.
The film layer structure of first substrate 1 in the implementation of the application is simply introduced below:
As shown in figure 13, in its Fig. 7 provided by the embodiment of the present invention DD ' positions profile, from first substrate 1 to On the direction 200 of second substrate 2, first substrate 1 includes substrate layer 50, active layer 11, grid layer 14, capacitance electrode layer 15.Its In, said structure is arranged in display area 10, also, the first substrate 1 further includes the source electrode being electrically connected with active layer 11 18 are electrically connected with drain electrode 17, source electrode 18 or drain electrode 17 with anode (not shown), anode and luminescent layer (not shown) It is electrically connected, is additionally provided with cathode (not shown) on luminescent layer, applies voltage between the anode and cathode, then luminescent layer is launched Go out visible ray.
It is exemplary it is apparent that insulating layer can be set between each Rotating fields, with continued reference to Figure 13, active layer 11 with Gate insulator 12 is provided between grid layer 14, the first interlayer insulating film is provided between grid layer 14 and capacitance electrode layer 15 13, the second interlayer insulating film 16 is provided between capacitance electrode layer 15 and source electrode 18 and/or drain electrode 17, and in source electrode 18 And/it is additionally provided with passivation layer 19 between drain electrode 17 and anode.
