Description
Technical field
The present invention relates to technical field of flat panel display, relate in particular to a kind of capacitance type touch-control panel and preparation method thereof.
Background technology
Contact panel is divided into electric resistance touch-control panel, capacitance type touch-control panel, infrared type contact panel and sound wave type contact panel according to the difference of its touch-control principle.
Resistance-type, infrared type, sound wave type contact panel are not suitable for use in the operation interface of hand-held mobile terminal owing to the defective that its principle of work causes.Capacitance type touch-control panel is widely used in hand-held mobile terminal because its touch-control sensitivity is good, long service life, difficult by advantages such as outer signals interference.
Capacitance type touch-control panel further is divided into surface capacitance type contact panel and projected capacitive touch panel again.The surface capacitance type contact panel is owing to only can realize single-point touch, and therefore, its range of application is not extensive yet.And projected capacitive touch panel is because it can realize that multi-point touch is widely used.
Projected capacitive touch panel comprises substrate, X-axis sensing electrode layer, Y-axis sensing electrode layer.X-axis sensing electrode layer and Y-axis sensing electrode layer are formed at two opposing surfaces of substrate respectively.X-axis sensing electrode layer comprises that many are parallel to each other and X-axis induction electrode tandem spaced apart; Y-axis sensing electrode layer comprises that many are parallel to each other and Y-axis induction electrode tandem spaced apart, and X-axis induction electrode tandem and Y-axis induction electrode tandem are perpendicular in the projection that is parallel on the plane of substrate.Two sensing electrode layers of this kind projected capacitive touch panel are owing to be made in two opposing surfaces of substrate; After when making, needing to have made the sensing electrode layer of a side earlier; Substrate overturn; Make the sensing electrode layer of opposite side again; Therefore; Its that side sensing electrode layer that easy scratch completes earlier in manufacturing process; Cause induction electrode tandem on the sensing electrode layer to come off or the part of same sensing electrode tandem is cut off, make the projected capacitive touch panel that completes the defective that touch-control lost efficacy occur.
Therefore industry works out alternative structure, promptly makes two sensing electrode layers at the homonymy of substrate, and two sensing electrode layers separate through dielectric film.In the right this structure, successively occur aberration easily between the two-layer sensing electrode layer of Zhi Zuoing, and the overlaying structure of two sensing electrode layers and dielectric film also greatly reduces the transmitance of projected capacitive touch panel.
Therefore; Industry is developed the projected capacitive touch panel of bridging structure again; It is the same surface that X-axis induction electrode tandem and Y-axis induction electrode tandem all are located at substrate; And it is a plurality of Y-axis sensing units that each Y-axis induction electrode tandem is cut off by X-axis induction electrode tandem; And a plurality of Y-axis sensing units of same Y-axis induction electrode tandem are serially connected through connecting line, and connecting line and X-axis sensing electrode tandem overlapping are opened through the collets insulation.The projected capacitive touch panel of this bridging structure is compared with the above-mentioned projected capacitive touch panel that is positioned at the structure on two sides of substrate homonymy, has the transmitance height, the advantage that touch-control is sensitive.
But; Because the thickness of collets more is prone to scratch than induction electrode material much larger than the thickness and the collets material of induction electrode; Collets that in subsequent handling, cause owing to operation or the connection electrode on the collets scratch broken string, the occurrence probability that comes off is bigger, thereby influence the touch-control function of contact panel.Usually reach micron order (as common 1.5 microns or 2.0 microns) because of collets thickness again; The size of single collets is at hundred micron orders (like common 100*200 micron); So big or small collets, thus " babysbreath " phenomenon that causes outward appearance seen in appearance easily.
