Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
A kind of cover-plate glass stepped construction that the utility model is provided, at least has the advantage that：
The utility model uses the cover-plate glass stepped construction without PET base material, and the cover-plate glass stepped construction is included
UV glue-lines both be used for provide hardness support tack coat, while texture can be formed.The UV glue-lines are compounded with UV texture layers and hard
Change the dual-use function of layer, the effect that double-layer structure is brought can be realized using a Rotating fields, therefore, cover plate glass of the present utility model
The thickness of glass stepped construction is obviously reduced compared to the thickness of traditional structure with PET base material, so as to meet with touch-control
The thinning of the electronic product of function, the trend demand gently changed.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
