When being bent on supporting surface, the position of bending have naturally can open up the geometrical property (i.e. Gaussian curvature is zero) of bending without
Easily there is irregular local concavo-convex (Gaussian curvature is not zero), even if supporting surface has slight uneven, also can be
Above-mentioned each film layer is covered.In a preferred scheme of the present utility model, above-mentioned each functional layer is before supporting surface is adhered to
There is flat shape, thus, when its stickup is on the support surface and when bending, its crooked position is due to bullet being present under nature
Property deformation and there is equally distributed bending stress, bending stress can keep the curved surface of display layer, inductive layer or protective layer
Obtain more smooth.
In a preferred scheme of the present utility model, there is respective bending just should for the display layer, inductive layer, protective layer
Power neutral surface.The display layer, inductive layer, protective layer have respective bending normal stresses neutral surface, i.e., above-mentioned each functional layer is each
From after bending, tension and compression are alternately distributed within the lamination that above three functional layer is formed so that
Stress in above-mentioned lamination will not be excessive, thus can avoid being stacked in the presence of stress itself and deforming, specifically,
In order that the display layer, inductive layer, protective layer have respective bending normal stresses neutral surface, this touching display screen is being made
When, preferably display layer, inductive layer and protective layer are attached on the supporting surface of supporting plate successively, rather than by display layer, sensing
Layer, protective layer first cling again overall attach on supporting surface.
Curved surface touching display screen provided by the utility model, its display layer, inductive layer and protective layer are successively adhered to rigidity
On the bent support face that supporting plate is provided, because supporting surface is the face with developable surface geometrical property, above-mentioned each functional layer
The supporting surface general shape for also becoming developable surface afterwards is adhered to, so as to form the curved surface of touch control display apparatus.With it is existing
Technology is compared, and it need not use the hot bending process compared with heavy sheet glass substrate to be made, and thus avoid this technique and brought
It is local concavo-convex, thus its curved surface has good planarization, and its outward appearance is preferable.In addition, the utility model is carried
The curved surface touching display screen of confession, its each functional layer are also kept for the advantages of smooth in the case where bending stress be present with self.
