Description
Technical field
The utility model relates to the production technical field of curved touch screen more particularly to the plastic package dies of curved touch screen.
Background technique
Touch screen is combined and is formed by cover board and touch-control vane, wherein determines that the factor of touch screen shape mainly has two
A, one of them is the shape of cover board, second is that the mode that cover board and touch-control vane are fixed.In the prior art, the system of touch screen
The method of making is first individually to be manufactured cover board and touch-control vane, is then again fixed on cover board and the assembly of touch-control vane
Together, which can only produce the 2.5D touch screen of the regular shape touch screen either curved edge of no curved surface, and
It is difficult to produce the touch screen of curve special (irregular curve form), so as to cause touch screen shape base in the prior art
This is all the 2.5D shape of the regular shape either curved edge of no curved surface, and the curved surface for Irregular Boundary Surface shape seldom occur is different
Shape touch screen, and then it is difficult to meet the needs of user is to curve special touch screen.Specifically, the manufacturing method of existing touch screen is difficult
It is mainly as caused by following two reason to produce curve special touch screen:
1) one reason for this is that: use existing equipment, it is difficult to process curve special (irregular curve form) lid
Plate or processing yield are low, do not have production condition.
2) another the reason is that: even if solving the problems, such as the production of curve special cover board, subsequent curve special cover board
Fixed with the assembly of touch-control vane is also a stubborn problem, is embodied in: in the prior art, cover board and functional sheet
Fixed form is to be fixed using panel turnover machine either glue machine by optical cement (point solid-state and liquid).Wherein, solid-state light
Glue is OCA (Optically Clear Adhesive), is only suitable for making OCA be attached to cover board and touch-control sensing with panel turnover machine
On piece simultaneously fixes the two, and panel turnover machine can only be such that OCA is fitted on plane class cover board or touch-control vane.Liquid glue is
LOCA (Liquid Optical Clear Adhesive) is only suitable for making LOCA be attached to cover board and touch-control biography with glue machine
Sense on piece simultaneously fixes the two, and glue machine can only be such that LOCA is fitted on plane class cover board or touch-control vane.
