Background technology
From Iphone, Ipad begins, and capacitance type touch control screen (CTP) technology begins to get into practical stage in enormous quantities; Along with MID (moving InterWorking Equipment); The mass development of digital products such as smart mobile phone, the untouchable touch technology of capacitance type touch control screen are brought sensitive touch-control sensation, better visual effect; Longer serviceable life and more humane product integral product appearance design; Obtain people's approval and like, beginning becomes the touch technology that attracts most attention in recent years to the industrial circle development.
Capacitance type touch control screen can be divided into two big types: 1, and the self-tolerant touch screen; 2, hold the formula touch screen mutually.The present invention is based on the structural modification of mutual appearance formula capacitive touch screen, so following explanation is based on mutual appearance formula touch screen structure.
The structure of at present main mutual appearance formula capacitive touch screen has following two kinds:
1, individual layer ITO individual layer GLASS structure (SITO):
Layering is following:
Protective seam (101) → metal conducting layer (102) → insulation course (103) → line influence layer (104) → glass-based flaggy (105) → screen layer (106).
2, double-deck ITO individual layer GLASS structure (DITO):
Layering is following:
Protective seam 1 (202) → metal conducting layer (203) → line influence layer 1 (201) → glass-based flaggy (204) → line influence layer 2 (206) → metal conducting layer (207) → protective seam 2 (206).
More than two kinds of structures all need set up circuit on the metal level, complex process, equipment is more expensive; Metal level " bridge mode " in the SITO structure in addition; Easy fracture is particularly damaged by ESD easily, and the two-sided ITO exposure technology in the DITO structure is complicated; And having increased exposure frequency, intractability is higher.
Summary of the invention
The technical matters that the utility model solves: mainly be through improvement to capacitive sensor structure; Remove the metal level manufacture craft in " individual layer ITO individual layer GLASS structure (SITO) " and " double-deck ITO individual layer GLASS structure (the DITO) " process of production; With the two-sided ITO exposure technology of removing in " double-deck ITO individual layer GLASS structure (DITO) "; Make and adopt a kind of novel structure, accomplish production capacitive transducer in the capacitance touch screen through simple equipment.
For the basic design that solves above technical matters the utility model be with optical cement with two single-glass baseplate-laminating modes together that are covered with the line influence layer, i.e. D-SGITO structure is accomplished the design to the capacitive touch screen sensor construction.
A kind of capacitive touch screen sensor; Comprise: glass-based flaggy 1 (301) one surface covers line influence layer 1 (302); Optical cement bonding coat (303) covers to be put on line influence layer 1 (302); The opposite side of optical cement bonding coat (303) covers glass-based flaggy 2 (304); The opposite side of glass-based flaggy 2 (304) covers line influence layer 2 (305), and line influence layer 2 (305) opposite side cover protective seam (307), and line influence layer 1 (302), line influence layer 2 (305) are connected with the external drive chip interface through metal conducting layer (306).
As the further improvement of the utility model, said metal conducting layer (306) conducting wire is a flexible PCB.
Further improvement as the utility model; Be covered with the glass-based flaggy 1 (301) and the described glass-based flaggy 2 (304) that is covered with line influence layer 2 (305) of line influence layer 1 (302) described in the said improved hierarchy, the frame mode that adopts optical cement bonding coat (303) to fit.
As the further improvement of the utility model, said line influence layer 1 (302) and line influence layer 2 (305) are made up of following figure: one of them angle of W shape, rectangle, triangle or triangle is the irregular figure of circular arc or trapezoidal.
More than improve the Sensor Design and the exploitation that can on the LCD existing equipment, realize capacitive touch screen, not only practice thrift huge equipment investment in early stage, improve and produce yield, practice thrift cost.
Description of drawings
Fig. 1 is individual layer ITO individual layer GLASS structure (SITO) structural drawing.
Fig. 2 is double-deck ITO individual layer GLASS structure (DITO) structural drawing.
Fig. 3 covers single-glass (GLASS) bonding structure (D-SGITO) structural drawing of individual layer ITO for two of the utility model.
