Description
Technical field
The invention belongs to the fields such as steel mesh printing, digital modeling and laser application more particularly to a kind of making projection-type electricity
Hold the method for printing screen of touch screen.
Background technology
Projecting type capacitor touch screen is the sensor film based on a kind of encapsulation micro wire, collects accurate sensing positioning, flexibility
And the advantages that high transparency, is integrated, and for the accurate touch-control positioning of 12 inches or more touch screens, is also applied to accurate interaction.
Projecting type capacitor technology is that one kind makes horizontal and vertical electrod-array, profit in glass or transparent membrane surface
Change to detect the touch-control of finger with these horizontal and vertical electrode capacitances, and be divided into according to the difference of the producing method of capacitance
For two types：
Self-capacitance screen is fabricated to laterally and longitudinally electrode array in glass or transparent membrane surface with transparent conductive material
Row, these horizontal and vertical electrodes form capacitance, the self-capacitance that this capacitance is just known as, that is, electricity with ground respectively
The capacitance of pole over the ground.When finger touches capacitance plate, the capacitance of finger will be added in screen body capacitance, make screen body capacitance amount
Increase.In touch detection, self-capacitance screen detects laterally and longitudinally electrod-array respectively successively, according to the change of capacitance before and after touch
Change, determine lateral coordinates and longitudinal coordinate respectively, be then combined into the touch coordinate of plane.The scan mode of self-capacitance, quite
In the touch point on touch screen is projected to X-axis and Y direction respectively, coordinate then is calculated in X-axis and Y direction respectively,
Finally it is combined into the coordinate of touch point.
Mutual capacitance screen makes transverse electrode and longitudinal direction electricity in the transparent conductive material of glass or transparent membrane surface
Pole, difference lies in the place that two arrays of electrodes intersects will form capacitance namely this two arrays of electrodes difference structure with self-capacitance screen for it
Into the two poles of the earth of capacitance.When finger touches capacitance plate, the coupling between two electrodes near touch point is affected, so as to change
The capacitance between the two electrodes is become.When detecting mutual capacitance size, lateral electrode sends out pumping signal successively, longitudinal
All electrodes receive signal simultaneously, can obtain the capacitance size of all horizontal and vertical electrode joints in this way, i.e., entirely
The capacitance size of the two dimensional surface of touch screen.According to touch screen two-dimensional capacitance change data, each touch can be calculated
The coordinate of point.Therefore, even if there are multiple touch points on screen, the true coordinate of each touch point can also be calculated.
Large touch screen (12 cun or more) market is mainly captured by infrared screen at present, and infrared screen is by the red of surrounding transmitting
Outside line can react come what is realized as long as having object to cut off infrared ray.Capacitance plate technically compares infrared screen with excellent
Gesture：
1. infrared screen has action as long as having thing to hinder to infrared ray, easily malfunction：For example winter long sleeves touch
Malfunction will be generated to capacitance plate；
2. infrared screen is not easy waterproof；
3. drift easily occurs under strong illumination for infrared screen even without action, open air is not suitable for using infrared screen；
4. the resolution ratio higher of capacitance plate, so the precision of product is much higher.
There are mainly two types of the methods for producing large-sized capacitance touching control film at present：
It is a kind of using conductive oil film spray printing heat-agglomerating into the production method of conductive electrode, conductive oil film in actual production
It is difficult to spray printing is controlled to go out the diameters of lines, and conductive oil film is easily splashed to nonprinting region and forms impure point.Print speed
It is slow.In addition, using 3D printing heat-agglomerating into the production method of conductive electrode, print speed compares in actual production
Slowly.
In conclusion the problems of large size capacitive touch control film is at present：Production technology is complicated, speed of production
Slowly, yield rate is low and of high cost.
