Abstract
The invention discloses a via-hole conductive material for an OGS capacitive touch screen and the application thereof. The via-hole conductive material comprises printing ink which is doped with conductive golden balls. Preferably, the particular size of each conductive golden ball is 5 microns to 30 microns. Due to the fact that the printing ink, the color of which is the same as that of the border, is doped with the conductive golden balls, the color of printing ink with local breakover is the same as that of non-conductive printing ink, breakover is realized under the condition of no naked-eye awareness, and breakover reliability is high.
Description
Technical field
The present invention relates to OGS capacitive touch screen, more precisely, relate to the hole-through conductive material in the manufacture craft of this capacitive touch screen, the invention still further relates to the application of this hole-through conductive material.
Background technology
One Glass Solution (being called for short OGS) directly forms a kind of technology of ITO conducting film and sensor on cover glass, makes a glass play the double action of cover glass and touch sensor simultaneously.The production firm of present capacitance plate; the structural design of its screen is divided into G+G, G+F substantially, G+F+F, OGS are several; wherein the thinnest the lightest product will be counted OGS design, and this structure is the integrated glass surface of having accomplished for the protection of touch-screen and display of touch function.Under this structure, according to the design of touch-screen drive IC, be divided into again two kinds of bridge formation (being commonly called as SITO) and individual layer multiple spots (being commonly called as caterpillar).
Manufacture craft of the prior art, its operating process is complicated, and some processing step, because most manufacturers do not possess manufacturing conditions, needs outsourcing to produce, and makes the production cycle, cost cannot be controlled.
Adopt hole-through conductive technology to process, if hole-through conductive material adopts silver slurry, first casting aside color does not say, concentrating the talk of conducting function may have the extruding of follow-up external force to tear after solidifying along with silver slurry again, and silver-colored lumps produces trickle be full of cracks and repeatedly can cause afterwards fracture to lose conducting function effect touch-screen quality.
