Description
Technical field
The present invention relates to a kind of mutual capacitance touchscreens functional sheets and preparation method thereof, for handset touch panel etc., belong to tactile
Touch screen research field.
Background technology
Projected capacitive screen can be divided into self-capacitance screen and mutual capacitance screen two types.It is (a kind of transparent with ITO in glass surface
Conductive material) laterally and longitudinally electrod-array is fabricated to, these horizontal and vertical electrodes form capacitance with ground respectively, this electricity
Hold the self-capacitance being just known as, that is, the capacitance of electrode over the ground.When finger touches capacitance plate, the capacitance of finger will
It can be added in screen body capacitance, increase screen body capacitance amount.
In touch detection, self-capacitance screen detects laterally and longitudinally electrod-array respectively successively, according to capacitance before and after touch
Variation, determine lateral coordinates and longitudinal coordinate respectively, be then combined into the touch coordinate of plane.The scan mode of self-capacitance,
It is equivalent to and the touch point on touch screen is projected to X-axis and Y direction respectively, then calculate seat in X-axis and Y direction respectively
Mark is finally combined into the coordinate of touch point.
Then all it is unique in the projection of X-axis and Y direction, the coordinate being combined into is also unique if single-touch
's；If there are two touches and not in same X-direction or same Y-direction on the touchscreen at this 2 points, in X and Y-direction
Respectively there are two projecting, then 4 coordinates are combined into.Obviously, only there are two coordinate be true, other two is exactly what is be commonly called as "
Terrible point ".Therefore, self-capacitance screen can not realize real multiple point touching.
Mutual capacitance screen is also to make transverse electrode and longitudinal electrode in glass surface ITO, its difference with self-capacitance screen
It is, the place that two arrays of electrodes intersects will form capacitance namely this two arrays of electrodes has respectively constituted the two poles of the earth of capacitance.Work as finger
When touching capacitance plate, coupling of the touch point nearby between two electrodes is affected, so as to change between the two electrodes
Capacitance.When detecting mutual capacitance size, lateral electrode sends out pumping signal successively, and longitudinal all electrodes receive letter simultaneously
Number, the capacitance sizes of all horizontal and vertical electrode joints can be obtained in this way, i.e., the two dimensional surface of entire touch screen
Capacitance size.According to touch screen two-dimensional capacitance change data, the coordinate of each touch point can be calculated.Therefore, on screen
Even if there are multiple touch points, the true coordinate of each touch point can be also calculated.
Thus high-end handsets preferably touch experience effect to realize now, mainly using mutual capacitance type touch screen.
The it is proposed of full fitting concept is mainly since the capacitance screen touch screen of early stage with being bonded for display panel is mainly frame
Actually there are still the airspace of 0.5mm or so between sticking structure, i.e. touch screen and display panel, due to the original of capacitance touch
Reason is limited, this partial air layer (being equivalent to the non-conductive layer of insulation) can influence to touch effect, simultaneously because the effect of air refraction
Fruit shows through the image on touch screen viewing display panel, can lead to the problem of reflective, the situation especially in sunlight irradiation
Under, it is difficult to see display panel pattern clearly, thus the high-end flagship mobile phone of existing market mainstream can be eliminated using full laminating type
Capacitance touch screen and display panel are carried out adhesion by optical cement, present and preferably touch display effect by air space.
There are mainly three types of mainstream production programs for mutual capacitance touchscreens functional sheet:
First, single-layer double-side ITO structure PET, tow sides ITO need to process；
Since the not bending resistance and PET film material of ITO are very thin, and positive and negative ITO is needed by individually adding twice
Work, process is numerous and diverse, thus ITO injureds are bad very high, especially when processing one side ITO, the patterning of secondary complexity needed to add
Work, another side (i.e. back side ITO) are easily broken off, and yields is low；Simultaneously because there is two layers of ITO, it is easy to during finished product use
Since bending leads to dysfunction
2nd, mono-layer single-face ITO structure PET adds metal to put up a bridge；
Since metal bridging craft precision requires high, difficult and not resistant to bending, while metal bridging structure is made on PET
Edge scribing line experience effect is poor, and the metal bright spot of the inside can be seen in while making finished product
3rd, it using dual-layer, single-sided ITO structure PET, is needed between PET and PET with OCA adhesions；
Due to the use of double-layer PET, integral thickness is partially thick, using the single side ITO structure PET of 50 most thin at present micron thickness as
Example, using double-layer PET, one layer of 50 microns of OCA of centre fitting, integral thickness reaches 150 microns, is the 3 of first two scheme thickness
Times.
Conventional condenser touch sensing can not realize preferable flexibility because using traditional material ITO, equally,
Be difficult due to the intrinsic property of ITO, when making transparent conductive electrode accomplish it is ultra-thin.But with flexible electronic and wearable industry
Flourish, the demand of ultra-thin super soft capacitance touching control sensor is increasing, and existing scheme is generally based on ITO, lead to
Extremely complex technique is crossed, the ultra-thin capacitance touching control sensor of slight flexibility can be prepared, but its cost is very high
Expensive, yield is relatively low, can not meet the needs of market.

And corresponding conductor layer is patterned respectively, realizes capacitance touching control sensor integral thickness ultra-thin；Simultaneously because stone
Black alkene in itself have bending resistance characteristic, thus make entire functional sheet have bending resistance characteristic (towards ITO conductive layer direction bending without
Damage graphene layer line function).Since graphene processing graphic patternization is simple for process, power need to reach during such as ITO laser ablations
12w, and power only needs 4w during graphene laser ablation, and back side ITO layer will not be caused to damage, and can substantially reduce the difficulty of technique
Degree improves integrated artistic yield.Simultaneously as two-sided be all bonded using optical cement, can be used directly to be bonded hand entirely
The making of machine adapts to current technology overall development direction.
