Capacitance type touch control screen utilizes the electric current of human body to respond to carry out work, when the finger touch of user is on capacitance type touch control screen, due to human body electric field, user and capacitance touching control screen surfaces are formed with a coupling capacitance (for high-frequency current, electric capacity can be considered as conductor), siphon away a very little electric current so point from the touch point of capacitance touching control screen surfaces, this electric current divides and flows out from the electrode the corner of capacitance type touch control screen.The electric current flowing through these four electrodes is directly proportional to the distance of finger to corner, and controller, by the accurate Calculation to these four current ratios, draws the position of touch point.
Existing capacitance type touch control screen generally includes following main element: at glass or poly terephthalic acid class (PET, Polyethylene Terephthalate) base material plates the nano indium tin metal oxide ITO sensor of indium tin metal oxide (ITO, Indium Tin Oxides) pattern; To the cover plate (Cover Lens) that ITO sensor shields; For bonding the optics double faced adhesive tape of ITO sensor and Cover Lens; For calculating touch point and returning to the flexible PCB of processor.
Existing integrated touch-control (OGS, One Glass Solution) capacitive touch screen is reach the ink or photoresistance that appearance adopts, the energy of laser-induced thermal etching cannot be born, therefore the gold-tinted etch process that adopts makes more, so die cost, processing cost are higher, and due to the restriction of technique and former material, color is comparatively single.
Application number be 201210181269.5 Chinese patent disclose the patent of invention that name is called " a kind of capacitive touch screen with single-layer structure ", it comprises the cover plate of display screen, protection display screen, cover plate is provided with ITO sensor, and ITO sensor is by printing etching, radium-shine or gold-tinted technique system on the cover board; Which alleviates thickness and the weight of product, but adopt gold-tinted technique, add die cost, improve the processing cost of enterprise.
Utility model content
Technical problem to be solved in the utility model is, there is provided a kind of based on high temperature resistant and single glass structure capacitive touch screen that is laser-induced thermal etching ink, can when ensureing touch-control effect, reduce die cost and processing cost, shorten product development cycle simultaneously, and possess the appearance of multiple color.
In order to solve the problems of the technologies described above, the utility model provides a kind of based on high temperature resistant and single glass structure capacitive touch screen that is laser-induced thermal etching ink, comprise: the tempered glass directly serving as capacitive touch screen front panel, described capacitive touch screen also comprises: for generation of the ink layer of appearance; Described ink layer is printed on tempered glass, is ink layer that is high temperature resistant and laser-induced thermal etching; For sensing the sensor of touch point, described sensor is be plated in the particular conductivity figure that whole conductive layer inside tempered glass be processed into; Be connected with described sensor, for calculating touch point and returning to the flexible PCB of processor.
Further, the temperature that ink layer can bear is greater than 280 °.
A kind of single glass structure capacitive touch screen based on full laser etch process that the utility model provides at least has the following advantages:
(1) die cost and processing cost is reduced.Existing capacitive touch screen technology in various degree there is die cost and the high problem of processing cost, what the utility model provided can select full laser etch process based on high temperature resistant and single glass structure capacitive touch screen that is laser-induced thermal etching ink, do not need out processing mold, conductive pattern only needs one laser-induced thermal etching to complete;
