In the case of, the technology, method and apparatus should be considered as part of specification.
It is shown here and discuss all examples in, any occurrence should be construed as merely illustratively, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
The present invention relates to a kind of flexible touch sensing and flexible touch control display apparatus, Fig. 1 is flexible touching in the prior art
The top view of sensor is controlled, Fig. 2 is cross-sectional view of the flexibility touch sensing shown in Fig. 1 along the direction A-A1;As depicted in figs. 1 and 2,
When making flexible touch sensing, flexible substrate layer 102, electrode layer 103 and support film layer are sequentially prepared on glass substrate 101
104, wherein electrode layer 103 is provided with touch control electrode 131.In one direction, the length of setting support film layer 104 is less than soft
Property substrate layer 102 length so that support 104 relative flexibility substrate layer 102 of film layer formed stepped region T to bind touch-control circuit plate
105, i.e. support film layer 104 is covered on the region other than the T of stepped region.Touch-control circuit plate 105 draws touch-control cabling 132, warp
Stepped region T cabling is connected to touch area with the touch control electrode 131 in electrode layer 103.
After the completion of the preparation of flexible touch sensing, glass substrate 101 and flexible substrate layer 102 are shelled by laser technology
It leaves, then the flexible touch sensing made is combined with flexible display panels, form flexible touch device.It is flexible
After touch device is formed, during quality testing, the problem of it is bad often to will appear touch-control, touch-control control accuracy difference, in this regard,
In terms of inventor is the study found that mainly there is following two in the reason of leading to the above problem: being on the one hand, flexible touch sensing
The phenomenon that often will appear broken string, after broken string, influences the transmitting of touching signals, causes touch-control bad;Further aspect is that flexible
When touch sensing is combined with flexible display panels, often will appear contraposition inaccuracy phenomenon, flexible touch sensing with it is soft
Property display panel contraposition be not allowed to will affect touch-control control precision.
Based on this, inventor further study show that, in a first aspect, broken string the phenomenon that typically occur in glass substrate
After 101 remove with flexible substrate layer 102, and above problem Producing reason and support film layer 104 only cover touch area and have
It closes, for the stepped region T of flexible touch sensing, after removing glass substrate 101, is not supported the covering of film layer 104, only remains
Lower flexible substrate layer 102 and touch-control cabling 132, since 102 matter of flexible substrate layer is soft easily-deformable, the ability that meets with stresses is small, causes
The flexible substrate layer 102 of stepped region T, the especially corner location of stepped region T is deformed vulnerable to shock, during deformation,
It is very easy to appear in the touch-control cabling 132 that stepped region T is connected with touch-control circuit plate 105 that there is a phenomenon where be broken.For
The reason of two aspects, flexible touch sensing and flexible display panels contraposition inaccuracy also only covers touching with support film layer 104
It is related to control region, when flexible touch sensing is combined with flexible display panels, the corner of the stepped region T of flexible touch sensing
Position does not support film layer 104 to cover, and is easy to appear curling, and corner once crimps, and is easy to that contraposition inaccuracy occurs
Phenomenon.
Flexibility touch sensing provided by the invention and flexible touch control display apparatus only change on the basis of original processing procedure
The structure design for becoming support film layer can reduce the risk of touch-control cabling broken string, reduce flexible touch sensing and Flexible Displays
The risk of inaccuracy is aligned when panel combination, specifically, setting support film layer covers flexible substrate layer, and close to binding area
Marginal position designs notch, and notch is made to expose binding area, realizes the normal binding of touch-control circuit plate, touch-control circuit plate and touching
The other positions except area are being bound in the electrical connection for controlling electrode, and support film layer, which still is able to play, increases flexible touch sensing
The effect of thickness and intensity can increase support film layer to the guarantor of touch-control cabling compared with flexible touch sensing shown in fig. 1
Shield effect increases the rigidity characteristics of flexible touch sensing and is not easy to crimp, removes when by the glass substrate under flexible substrate layer
Afterwards, in the region of stepped region T shown in Fig. 1, still support protective effect of the Supported film layer to touch-control cabling, even if touching
It hits, guarantees that flexible touch sensing is unlikely to deform due to binding the setting of pad in the region of support membrane break mouth, supporting
The region of the non-notch of film layer can also reduce the risk of flexible touch sensing deformation due to the covering of support film layer, hence for
Flexible touch sensing is whole, when being hit, the problem of being not susceptible to deform, and then be also less prone to broken string.Meanwhile
The region of support membrane break mouth, binding pad enhance the rigidity of flexible touch sensing, in the region of the support non-notch of film layer, by
In the covering of support film layer, can also enhance the rigidity of flexible touch sensing, it is whole hence for flexible touch sensing, with
When flexible display panels combine, it is less prone to curling, and then be also less prone to due to curling and align inaccurate problem.The present invention
The design of support film layer structure can reduce the broken string risk of touch-control cabling in flexible touch sensing, reduce flexible touch-control sensing
The risk of inaccuracy is aligned when device is combined with flexible display panels.
