Description
Technical field
This utility model belongs to touch screen technology field, particularly relates to a kind of capacitive touch screen and has this
The electronic product of capacitive touch screen.
Background technology
In recent years, along with lifting and the development of electronic technology of electronic device, capacitive touch screen skill
Art application in the electronic equipments such as mobile phone, panel computer, PMP, navigator has had the development advanced by leaps and bounds.
The anticipated coming years, China's smart mobile phone industry will keep double-digit fast development, it is contemplated that 2016,
Intelligent machine overall yield is up to 8.0 hundred million.According to statistics from the intelligence in the market of 2009 to 2016 years China
Mobile phone shipment amount total can be up to 3,000,000,000.
Along with the iPhone/ipad extensive universal and evolution of technology in mobile phone and mancarried electronic aid,
The application of capacitive touch screen the most increasingly diversification, from hand-held device up to household appliances, condenser type
Touching technique is the most omnipresent.So the component market of capacitance touch screen products necessarily also comprises huge
Market value.The structure of capacitive touch screen mainly plates the thin-film conductor layers of layer of transparent in glass screen,
Protecting glass at the additional lastblock of conductor layer again, double Glass Design can thoroughly protect conductor layer and induction apparatus.
For the state of the art of capacitive touch screen control chip, capacitive touch screen is mainly by human body
Electric current sensing be operated.Capacitive touch screen is one piece of four layers of compound glass screen, the interior table of glass screen

This utility model embodiment provides a kind of capacitive touch screen, and this capacitive touch screen is applied to mobile phone, when
So, in other embodiments, this capacitive touch screen can also be used for panel computer, electronic reader etc., at this
The field that is applied to does not limits.
Specifically, shown in Figure 1, this capacitive touch screen includes touch-control display panel 10, and is located at
The ito film layer (not shown) of touch-control display panel 10 one side, ito film layer is capacitance touch
The capacitance sensing parts of screen, ito film layer is to make transverse electrode and longitudinal electrode, and two arrays of electrodes mutually forms
Electric capacity, this two arrays of electrodes has respectively constituted the two poles of the earth of electric capacity.When finger touches capacitance plate, have impact on tactile
Touch the coupling between two electrodes near a little, thus change the capacitance between the two electrode.Detection is mutually
During capacitance size, to electrode send pumping signal successively, longitudinal all electrodes receive signal simultaneously, this
Sample can obtain the capacitance size of all horizontal and vertical electrode joints.When human finger close to time, meeting
Cause local electric capacity to reduce, according to touch screen capacitance change data, each touch point can be calculated
Coordinate.Even if therefore screen is upper multiple touch point, the true coordinate of each touch point also can be calculated.
In this utility model embodiment, this touch-control display panel 10 has touch-control surface 11 for touch,
That is to say and apply in reality, user can directly directly be touched by finger, and realize based on this and have this

22 are made by ITO, when user directly touches receiving terminal ITO portion 21 by finger, and finger is carried
Electric charge can be assembled in receiving terminal ITO portion 21, is then delivered to induction end ITO portion by connecting lead wire 23
22, now, the electric charge that the electric charge finger that induction end ITO portion 22 is assembled is carried is consistent, and realizes sense
The touch of the corresponding virtual key in ITO portion 22 should be held, that is to say when finger touches receiving terminal ITO portion 21,
Be equivalent to finger touch in described touch-sensitive area 111 corresponding with position, induction end ITO portion 22 virtual by
Key, so, controls the virtual key of touch-sensitive area 111 in non-tactile induction zone 112.Based on this,
In application process, induction end ITO portion 22 can be arranged in touch-sensitive area 111 and be not easy to finger touch
Virtual key at, and receiving terminal ITO portion 21 is arranged at and finger is easy in non-tactile induction zone 112 touches
The position of control, this addresses the problem in prior art and cannot control completely due to the restriction of finger length size
Whole electric capacity is the situation of touch screen.
We are when the interface of operation of capacitor formula touch screen under normal circumstances, by the void at finger clicking operation interface
Intending at button, at this moment electrically charged due to human body, finger will necessarily form one with touch point and couple electric capacity, right
For high frequency electric, electric capacity is direct conductor, and the coupling electric capacity formed during touch-control can affect circuit entirety electricity
Holding characteristic, such controller, by calculating capacitance variation, judges the particular location of touch point, controls
The operation of driver.
In this utility model embodiment, connecting lead wire 23 is attached to non-tactile induction zone 112, connecting lead wire 23
The connecting lead wire 23 being made up of ITO, and receiving terminal ITO portion 21, receiving terminal ITO portion 21 and connection draw
Line 23 is wholely set.So, during manufacturing, it is simple to receiving terminal ITO portion 21, receiving terminal ITO
Portion 21 and connecting lead wire 23 are manufactured in the lump, improve production efficiency.
