According to the invention, the sensitization and conductive material is adopted to realize the manufacturing of the capacitance type touch screen wire circuit; the manufacturing of ultrathin circuit of printed circuit is realized to satisfy the using requirement; meanwhile, the problems of complex technology, low using rate, difficulty in increasing yield, and huge cost consumption caused by adopting physical vacuum plating metal conductive membrane method.
Description
Technical field
The present invention relates to the touch technology field, relate in particular to a kind of conducting circuit of capacitive touch screen method for making.
Background technology
Along with the fast development of electronic technology, the use of touch-screen is more and more extensive.Touch-screen is a kind of man-machine interface that can operate electronic equipment by display screen, allows the user to carry out direct touch control at this interface.Existing touch-screen has resistive touch screen, capacitive touch screen, infrared-type touch-screen and ultrasonic surface formula touch-screen.Wherein, capacitive touch screen has been widely applied in each field because it has the advantages such as the life-span is long, degree of accuracy is high, the volume production feasibility is strong, and so-called capacitive touch screen is exactly the touch-screen that a kind of peculiar electrical characteristics of utilizing human body reach the touch control operation purpose.The method for making of existing touch-screen conducting wire has: adopt serigraphy directly to make the Ag circuit, because the defective of silk-screen printing technique and the characteristic of printing material, so that printed wire can't be made ultra fine-line, cause the product frame to dwindle, do not satisfy user demand.Also have a kind of preparation method to prepare the multiply conducting wire by the finite space in the non-viewing area of touch-screen, the technological process that adopts at present is first physical vacuum plating Gu film, then expose, development and etching, make metal conductive film become the metallic conduction circuit, because the metal Cu itself that plating Cu technique is used does not possess photosensitive property, so must realize that circuit makes with the mode that applies photoresist, so just cause that making technology is complicated, the materials'use rate is low, the difficult cost consumption that causes of Yield lmproved is huge.
Summary of the invention
Purpose of the present invention is intended to solve prior art and adopts the problem of serigraphy existence and adopt the complex process of plating Gu film existence, the problem that the materials'use rate is low, Yield lmproved is difficult and cost consumption is huge, thereby a kind of conducting circuit of capacitive touch screen method for making is provided.
To achieve these goals, the invention provides a kind of conducting circuit of capacitive touch screen method for making.The method comprises: the visible area at the touch screen function sheet is made the electrically conducting transparent figure; Apply the conductive photoreceptor material at the touch screen function sheet of finishing the electrically conducting transparent graphic making; The touch screen function sheet that applies the conductive photoreceptor material is exposed, develops, realize the making of the peripheral conducting wire of visible area.
Preferably, the mode of described coating conductive photoreceptor material comprises a kind of in serigraphy, rotary coating and the roller coating method.
Preferably, describedly apply the conductive photoreceptor material at the touch screen function sheet and comprise one of following manner: apply the conductive photoreceptor material at the non-visible area of touch screen function sheet; Or at whole touch screen function sheet coating conductive photoreceptor material.
Preferably, described conductive photoreceptor material is for adding the silver slurry of emulsion.
The present invention has realized the making of printed wire ultra fine-line by adopting the conductive photoreceptor material to realize that the conducting wire of capacitive touch screen makes, and satisfies user demand; The problem such as also can avoid simultaneously adopting complex process that the method for physical vacuum plating conducting film brings, the materials'use rate is low, Yield lmproved is difficult and cost consumption is huge has obviously improved product quality, has shortened technological process, promoted product yield and has reduced production cost.
