Description
Technical field
The present invention relates to technical field of touch-control display, more particularly to a kind of preparation method of touch control display apparatus.
Background technology
In consumption electronic products market now, collect touch controllable function has turned into portable electric product main flow hair in display
The trend of exhibition.Contact panel is applied to a variety of electronic products, such as smart mobile phone (Smart Phone), tablet personal computer
(Tablet PC), notebook computer (Notebook), navigator (Navigator), POS system, self-aided terminal (Self-
Service Terminals) and Medical Devices (Medical Equipment).Because user can be directed through on screen
The icon of display carries out operation with assigning instruction, therefore contact panel provides the hommization behaviour between user and electronic product
Make interface.
The above-mentioned electronic product with touch controllable function is a kind of display terminal that touch module is fitted in display module, patch
Conjunction is one of most important step in touch control display apparatus production process, and common applying method is to use OCA (Optically
Clear Adhesive, optical cement) surface of a touch module is applied to, then contraposition bonding is carried out with display module, make touch-screen
It is integral with display module, finally pass through a HTHP bubble removal step again, will be located at contact panel, display panel and
Bubble between contact panel and OCA, display panel and OCA can prevent face by vacuum defoamation technique, the deaeration technique
Light is passed through the air in bubble to reflect or reflect because of the presence of bubble in plate, improve touch control display apparatus
Visual and contrast.
However, in the fitting process of integrated capacitor formula touch screen (one glass solution, OGS) common at present
In, only can not complete deaeration by a deaeration technique.It is because the OGS is usually by the first induction electrode tandem and the
Two induction electrode tandems may be contained within the centre position on the surface of the same side of cover-plate glass, and ink barrier bed is arranged at together
The surrounding position on one surface, when being bonded due to OCA with contact panel, the inner surface of contact panel is not smooth, i.e. institute
State between ink barrier bed and cover-plate glass and segment difference be present, buffering occurs when OCA is depressed at ink barrier bed with roller
State, cause closely attach completely between OCA and the ink barrier bed that segment difference be present, therefore in contact panel inner surface
Coat OCA when have bubble, if this bubble after touch module is bonded with display module only by a deaeration technique, can make
It is incomplete into deaeration, it have impact on the binding yield and display effect of touch control display apparatus.
