Touch screen is that wherein capacitance type touch control screen is one the most frequently used in touch screen for the compound touch-screen on the electronic products such as mobile phone, e-book, digital camera.
Capacitance type touch control screen is to utilize the electric current induction of human body to carry out work, in the time that user's finger touch is on capacitance type touch control screen, due to people's bulk electric field, user and capacitance touching control screen surfaces form with a coupling capacitance (for high-frequency current, electric capacity can be considered as conductor), so finger siphons away a very little electric current from the touch point of capacitance touching control screen surfaces, this electric current divides in the electrode four jiaos from capacitance type touch control screen and flows out.The electric current of these four electrodes of flowing through is directly proportional to the distance of four jiaos to finger, 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 chief component element: at glass or poly terephthalic acid class (PET, Polyethylene Terephthalate) plate the nano indium tin metal oxide ITO sensor of indium tin metal oxide (ITO, Indium Tin Oxides) pattern on base material; The cover plate (Cover Lens) that ITO sensor is shielded; For the optics double faced adhesive tape of bonding ITO sensor and Cover Lens; For calculating touch point the return flexible PCB to processor.
Existing integrated touch-control (OGS, One Glass Solution) capacitive touch screen is to reach ink or the photoresistance that appearance effect adopts, cannot bear the energy of laser-induced thermal etching, therefore the gold-tinted etch processs that adopt are made more, so die cost, processing cost are higher, and due to the restriction of technique and former material, color is comparatively single.
Application number is that 201210181269.5 Chinese patent discloses name and is called " a kind of single layer structure capacitive touch screen ", 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; It has alleviated thickness and the weight of product, but adopts gold-tinted technique, has increased die cost, has promoted the processing cost of enterprise.
Summary of the invention
Technical matters to be solved by this invention is, provide a kind of based on high temperature resistant and single glass structure capacitive touch screen laser-induced thermal etching ink, can be in the situation that ensureing touch-control effect, reduce die cost and processing cost, shorten product development cycle simultaneously, and possess the appearance effect of multiple color.
In order to solve the problems of the technologies described above, the invention provides a kind of based on high temperature resistant and single glass structure capacitive touch screen laser-induced thermal etching ink, comprise: directly serve as the tempered glass of capacitive touch screen front panel, described capacitive touch screen also comprises: for generation of the ink layer of appearance effect; Described ink layer is printed on tempered glass, is the ink layer of high temperature resistant and laser-induced thermal etching; For the sensor of sensing touch point, described sensor is to be plated in the particular conductivity figure that whole conductive layer of tempered glass inner side is processed into; Be connected with described sensor, for calculating touch point the return flexible PCB to 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-induced thermal etching technique provided by the invention at least has the following advantages:
(1) reduce die cost and processing cost.Existing capacitive touch screen technology in various degree exist die cost and the high problem of processing cost, provided by the inventionly can select full laser-induced thermal etching technique based on high temperature resistant and single glass structure capacitive touch screen laser-induced thermal etching ink, do not need out processing mold, conductive pattern only needs one laser-induced thermal etching to complete;
(2) shorten product development cycle.Provided by the invention based on high temperature resistant and single glass structure capacitive touch screen laser-induced thermal etching ink, as select full laser-induced thermal etching technique, reduced opening period and multi-step process, and occurred that development problem point also only needs to adjust in real time etched figure, the whole development cycle reduces greatly;
(3) possesses the appearance effect of multiple color.Single glass structure capacitive touch screen based on high temperature resistant and laser-induced thermal etching ink provided by the invention, as selected full laser-induced thermal etching technique, can be avoided the restriction of gold-tinted technique to ink and photoresist layer, makes conventional black and white coloured appearance effect in addition.
