Injured is bad directly proportional to the thinness of hardened layer, i.e., hardened layer is thinner, and it is easier that hardened layer is bonded with glass substrate
It is bad to there is injured.
It is bonded bubble and fold is bad directly proportional to the thickness of hardened layer, i.e., hardened layer is thicker, hardened layer and glass substrate
More easily there is bubble or fold in fitting.
As shown in table 1, in embodiment 1 and embodiment 2, hardened layer is too thin, and hardened layer lies prostrate compared with being bonded with glass substrate
Patch, it is not easy to bubble or fold occur, but injured easily occur.Thus, the thin hardened layer in embodiment 1 is rolled over when being 0.5 μm
Hinder it is bad up to 22.5%, and be bonded bubble and fold it is bad it is low be 0.2%；Injured when thin hardened layer in embodiment 2 is 1 μm
It is bad up to 13.4%, and be bonded bubble and fold it is bad be 0.4%.
As shown in table 1, in the case where 1~embodiment of embodiment 7 is compared to each other, it is thus identified that 3~embodiment of embodiment 6
More preferably, this preferred thickness can guarantee that injured is bad in permissible scope to shown 2~10 μm of ratios of thin hardened layer, at the same time
Also it can guarantee that less fitting bubble and relatively low fold are bad.
In the case where 1~embodiment of embodiment 6 is compared to each other, it is thus identified that the hardening shown in 3~embodiment of embodiment 5
Layer thickness is more than or equal to 2 μm and can realize that hardened layer was bonded with glass substrate more preferably, this is more highly preferred to thickness less than 5 μm
Bubble is less and the bad relatively low effect of fold for the bad relatively low, fitting of journey injured, so as to be thinned cover-plate glass stepped construction
Integral thickness, so that the thinning for the electronic product for meeting there is touch controllable function, the trend demand gently changed.
The UV texture layers 60 are transferred on the hardened layer 50 by UV.Specifically, can when forming UV texture layers 60
The coating UV glue on the hardened layer 50 of formation, is then imprinted by template, UV glue is had specific pattern, UV glue is had spy
Fixed pattern, for example the specific patterns such as drawing pattern, CD lines or ripple glaze are set on UV glue-lines, then apply mask and cure and clear
Wash uncured UV glue, you can obtain the UV texture layers 60 being formed on hardened layer 50.
