Description
Technical field
The invention belongs to the technical field of touch-screen, more particularly to a kind of electronic equipment with touch-screen.
Background technology
Capacitive touch screen is equipped with now with very many electronic equipments.
The touch technology projected capacitive touch screen of projecting type capacitor panel is etched on two layers of ITO electro-conductive glass coating
Go out different ITO conducting wire modules.The figure etched in two modules is mutually perpendicular to, and they can be regarded as X and Y-direction
The draw runner of consecutive variations.Because X, Y framework are in different surfaces, its intersection forms a capacitive node.One draw runner can be treated as
Drives line, it is detection lines that another draw runner, which is treated as,.When electric current passes through a wire in drives line, if there is electric capacity in the external world
The signal of change, then the change of capacitive node on another layer conductor will be caused.Detect capacitance change can by with
Connected electronic loop measurement obtain, then via A/D controllers switch to digital signal by computer do calculation process acquirement (X,
Y) shaft position, and then with reaching the mesh of positioning.
During operation, controller successively flow to drives line by power supply, thus makes to form a specific electric field between each node and wire.So
After scan by column sense wire and measure its interelectrode capacitance change, so as to reach multipoint positioning.When finger or shake-up medium connect
When near, the capacitance that controller is predicted rapidly between touch-control node and wire changes, and then confirms the position of touch-control.A this axle
Driven, and then come out through the response of touch-screen by the electrode senses on other axles by a set of AC signals.Users
This is called ' crossing formula ' sensing, alternatively referred to as projection-type senses.X, the ITO pattern of Y-axis, when finger is touched are coated with sensor
During Touch Screen surface, the capacitance below touch points increases, the scanning of sensor continuity from above according to the distance of touch point
The change of capacitance is detected, control chip calculates touch point and returned to processor.
When being unable to good contact when user's finger and touch-screen, the capacitance variation very little between touch-control node and wire,
Even close to 0, touch location detection is caused to be forbidden, or even touch location can not be detected.
The content of the invention
Based on this, therefore the present invention primary mesh be to provide it is a kind of improve touch control device touch effect device and side
Method, the device and method with can solve the problem that finger and touch-screen system under non-good contact condition (such as：Equipment is placed on insulation
Desktop, equipment be placed on insulation leather sheath in) touch location detection forbidden, or even without output the problem of.
It is to provide the apparatus and method that a kind of improvement touch control device touches effect, the device another mesh of the present invention
It is with low cost and method realizes simplicity, it can be widely applied in existing electronic device touchscreen.
To achieve the above object, the technical scheme is that：
A kind of to improve the device that touch control device touches effect, it includes touch-screen, pressure sensor film layer, and its feature exists
Pressure sensor film layer is provided with the back side of the touch-screen, the pressure sensor film layer back side is provided with intermediate plate, described
There is appropriate gap between pressure sensor film layer and intermediate plate, to answer pressure changeable, pressure sensor membrane is easy to while also having
Layer calculates the effect of pressure position.
Further, the back of the intermediate plate, which is provided between bonnet, and the intermediate plate and bonnet, has accommodating chamber, described
Accommodating chamber is to accommodate touch-screen and pressure sensor film layer control pcb board used.
Further, battery is also provided with the accommodating chamber, to for the control circuit on pcb board and touch
Screen, pressure sensor film layer provide electric power.
Further, touch-screen control chip and pressure sensor film layer control chip are provided with the pcb board, with right
Touch location and pressure generation position are calculated.
Further, the pcb board is additionally provided with master chip, touch-screen control chip and pressure sensor the film layer control
Coremaking piece is all connected to master chip, and the particular location of touch-control is obtained by master chip, and receives the corresponding control of control instruction execution
System operation.
It is a kind of to improve the method that touch control device touches effect, it is characterised in that this method is same using touch-screen and modular pressure
When be operated, touch-screen be used for detect user touch positional information, modular pressure detection user touch pressure carry simultaneously
The positional information that voltage supply power is produced, collects after above- mentioned information, and the positional information that the positional information of touch and pressure are produced is reported
To system.
The modular pressure, is realized by pressure sensor film layer and its control chip.
Further, the positional information that the positional information of the touch and pressure are produced, is collected by master chip and is reported,
The position data of touch is transferred to touch-screen control chip by touch-screen, and the position data that pressure is produced is then by pressure sensor membrane
Layer is transferred to pressure sensor film layer control chip, calculates positional information, the pressure of touch by touch-screen control chip respectively
Sensor film layer control chip calculates the positional information of pressure generation, and the position that the positional information of touch and pressure are produced
Information transfer collects to master chip.
When user's finger and touch-screen system good contact when, touch-screen can draw accurate touch location, this
The pressure generation position that touch location and modular pressure are calculated be it is consistent, touch location that master chip calculates touch-screen and
The pressure position that modular pressure is calculated reports system.
Further, when user's finger and touch-screen system non-good contact when, what touch-screen control chip was calculated touches
Touch position inaccurate, or can't detect touch location, but modular pressure can normally calculate the position of pressure generation,
Now, there is difference in the information that master chip is aggregated into, and master chip can notify this result touch-screen control chip, touches
Shield control chip after this information is obtained, the modes such as reduction touch threshold that can sample recalculate user touch location.
Further, if after reduction threshold value, correct touch location can be obtained, master chip continues to use touch-screen
The touch location of calculating, if after reduction threshold value, touch-screen is still obtained less than correct touch location, then master chip is by pressure mould
The touch location that block is calculated reports system.
What the present invention was realized improves the apparatus and method that touch control device touches effect, because the device has pressure touch mould
Block, when finger is touched, pressure touch module can detect the change of pressure, while generation pressure can also be calculated
Position.In touch-screen because finger with the case that systematically non-good is contacted, using pressure touch module to touch location
It is identified, to improve the problem of touch-screen detection is inaccurate.
