Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for
It is bright, part relevant to the utility model is illustrated only for ease of description, in attached drawing rather than entire infrastructure.
As described in background, display panel structure in the prior art, there are non-display areas and external hanging type to touch
The problem of frame of screen bends complex process, increases the risk of touch screen rim area interior cabling fracture.Through inventor the study found that
The reason of this problem occur essentially consists in, and does not have between display function layer and touch function layer in the non-display area of display panel
There is glued construction also not deposit between display function layer and external hanging type touch screen in the non-display area when touch screen is external-hanging structure
In glued construction, spacing very little between display function layer and touch function layer (or external hanging type touch screen), so that display function
Layer is when being bent, it is necessary to bent together with touch function layer, because display function layer in non-display area and touch function layer it
Between glued construction is not present, touch function layer can restore to flatten, and touch function layer needs to undergo primary bending again, so that display surface
The process is more complicated for the bending of plate, and touch function layer needs to undergo bending process twice, so that in touch function layer bent area
Cabling be easily broken off.
For these reasons, the utility model provides a kind of technical solution of display panel, is this reality with reference to Fig. 1, Fig. 1
With a kind of cross section structure schematic diagram for display panel that new embodiment provides, including several functional layers, several functional layers
Lamination setting；Wherein, the first functional layer 100 and the second functional layer 200 are included at least in several functional layers；
Wherein, the first functional layer 100 includes the first bendable folding part 110, and the first bendable folding part 110 includes the first bent area
111 and first extension area 112；Second functional layer 200 includes the second bendable folding part 210, and the second bendable folding part 210 includes second curved
Folding area 211 and the second extension area 212；
First bent area 111 and the second bent area 211 are oppositely arranged, the first bendable folding part 110 and the second bendable folding part 210
Fitted by the first adhesive layer 310, the first adhesive layer 310 be at least set to the first extension area 112 and the second extension area 212 it
Between.
With reference to Fig. 1, several functional layers of display panel are stacked, between the first functional layer 100 and the second functional layer 200
It may include other function layer 400, such as polaroid etc..In order to realize the narrow frame of display panel, screen accounting, display panel are improved
Modular structure in a flattened condition, respectively by the first functional layer 100 and corresponding first driving chip, 500 bonding, the second function
Layer 200 with after corresponding second driving chip, 600 bonding, by 111 He of the first bent area of the first functional layer 100 of display panel
Second bent area 211 of the second functional layer 200 is bent simultaneously, such as the display panel luminous for unilateral side, and when bending can
Be the first functional layer 100 the first bent area 111 and the second functional layer 200 the second bent area 211 simultaneously to display surface
Then the opposite curving of plate light-emitting surface carries out bonding to the first functional layer 100.First due to the first functional layer 100 prolongs
Stretch in the second extension area 212 of area 112 and the second functional layer 200 that theres are the first adhesive layer 310, so that in the first functional layer of progress
When 100 bonding, the second bent area 211 of the second functional layer 200 will not restore to flatten, and keep bending state, no longer need to
Second bent area 211 of two functional layers 200 carries out second and bends, so that the bending technique of display panel is simplified, reduces
The bending number of second functional layer 200 of display panel.Simultaneously as leading in the second bent area 211 of the second functional layer 200
It often include metal routing, the reduction of the second bent area 211 bending number of the second functional layer 200 can reduce the second functional layer
The risk of 200 211 interior cabling of the second bent area fracture.When bonding, the first functional layer 100 can be with the first driving chip 500
Bonding is connected, the second functional layer 200 can be with 600 bonding of the second driving chip, the first driving chip 500 and the second driving chip
600 are connected by a flexible circuit board 700 with the mainboard (not shown) of display panel, specifically the flexible circuit board
700 can be connected by connector 800 with mainboard.Meanwhile first bendable folding part 110 the first extension area 112 between may exist
Keel 900 and the first functional layer 100 may include support membrane (not shown) close to the side of keel 900, so that
First bent area 111 and the second bent area 211 can keep certain crooked process radius, make the first bent area 111 and the second bending
Cabling in area 211 is not easy to break.Wherein, the first extension area 112 and the second extension area 212 can be with the light-emitting surfaces of display panel
In parallel, the first adhesive layer 310 can be pressure sensitive adhesive or Optical transparent adhesive.
It should be noted that being illustrated only in Fig. 1 viscous there are first in the first extension area 112 and the second extension area 212
The structure for tying layer 310, when other positions (such as the first bent area in the first bendable folding part 110 and the second bendable folding part 210
111 and second bent area 211) there is also when the first adhesive layer 310, the first functional layer 100 and the second functional layer 200 can be glued
That closes is even closer, more may be implemented to complete by once bending technique to the first bent area 111 and the second bent area 211
Bending simplifies the bending technique of display panel, reduces the bending number of the second functional layer 200 of display panel, reduces the second function
The effect of the risk of 200 second bent area of ergosphere, 211 interior cabling fracture.
Display panel provided in this embodiment, it is viscous by the way that first is arranged at least between the first extension area and the second extension area
Tie layer, allow the first functional layer and the second functional layer the first bent area and the second bent area bending by once bending
Technique realize, simplify the bending technique of display panel, at the same reduce the second functional layer because repeatedly bending caused by cabling break
The risk split.
