Description
Technical field
It the utility model is related to touchpad technology field, more particularly to a kind of touch circuitry with virtual key.
Background technology
Pen electricity and tablet personal computer are typically equipped with touch pad in the prior art, touch pad by equipped with physical button realize
Mouse right and left key, left button add dragging, and right button adds dragging etc. function.Generally there are two kinds of situations, there is a button among touch pad
Or each physical button of touch pad the right and left.
As shown in figure 1, touch circuitry 1 includes：Governor circuit 11, key circuit 12, for gathering touch partitioned signal
Sensor circuit 13 and finger-board and touch pad telecommunication circuit 14.Key circuit 12 is used to the left and right key signals collected being sent to
Governor circuit 11, sensor circuit 13 are used to the touch pad induced signal collected being sent to governor circuit 11, plate and touch
Board communications circuit 14 is arranged on keyboard circuit 1 and governor circuit 11 is direct, realizes that keyboard directly communicates with touch pad.It is whole to touch
Template is divided into the X of three areas, " left key area ", " right button area ", " coordinate turnover zone ", left key area and right button area for reading button,
Y-coordinate information, coordinate turnover zone are used for the X for reading cursor, Y-coordinate information.Sensor circuit 13 is used to read cursor moving area
The X of cursor, Y-coordinate information, key circuit 12 are used for the X for reading the button in left key area and right button area, Y-coordinate information.
But above-mentioned touch pad has following three big shortcomings：
1. one or two button is added to increase Material Cost and processing cost；
2. have the defective products that many buttons are bad or feel is bad during production；
3. the bad repairing machine of many buttons can be increased.
Utility model content
Therefore, technical problem to be solved in the utility model is：A kind of touch circuitry with virtual key is provided, with
Material Cost and processing cost are saved, reduces the fraction defective of production link, reduces the repair rate using link.
Then, the utility model provides a kind of touch circuitry with virtual key, including：Governor circuit, for reading
Take the sensor circuit of touch pad induction zone signal, finger-board and touch pad for realizing touch circuitry and keyboard circuit communication
Left virtual key region, right virtual key region and mobile cursor region, left virtual key region are divided into telecommunication circuit, touch pad sensing
With right virtual key region for reading the length information of button and being sent to governor circuit, mobile cursor region by sensor circuit
For reading the X of cursor, Y-coordinate information is simultaneously sent to governor circuit by sensor circuit.
Wherein, the governor circuit and keyboard circuit are also connected with computer respectively.
Touch circuitry described in the utility model with virtual key, eliminate key circuit and physics of the prior art
Button, do not changing on the basis of touch pad induction zone gathered circuit and the physical layer of signal originally in the prior art, pass through by
Left virtual key region, right virtual key region and mobile cursor region are divided into touch pad sensing, and left virtual key region and the right side are virtual
Key range is used for the length information for reading button and is sent to governor circuit by sensor circuit, and mobile cursor region is used to read
The X of cursor, Y-coordinate information and by way of sensor circuit is sent to governor circuit realize the read operation of keypress function.
Due to the removal of key circuit, Material Cost and processing cost have been saved, has been reduced because the production link that key circuit is brought
Fraction defective, reduce using link because repair rate caused by key circuit.

Embodiment
Below, the utility model is described in detail with reference to accompanying drawing.
As shown in Figure 2 and Figure 3, a kind of touch circuitry 3 with virtual key is present embodiments provided, including：Governor circuit
31st, for reading the sensor circuit 33 of touch pad induction zone signal, communicating for realizing touch circuitry 3 and keyboard circuit 2
Finger-board and touch pad telecommunication circuit 34.
Wherein, as shown in figure 3, left virtual key region, right virtual key region and mobile cursor area are divided into touch pad sensing
Domain, left virtual key region and right virtual key region are used to read the length information of button and are sent to master control by sensor circuit 33
Circuit 31, mobile cursor region are used for the X for reading cursor, and Y-coordinate information is simultaneously sent to governor circuit 31 by sensor circuit 33.
In addition, the governor circuit 31 and keyboard circuit 2 also respectively with computer（Do not identified in figure）Connection.
Specifically, touch circuitry 3 described in the present embodiment on the basis of the keyboard of prior art adds touch, removes button electricity
What road and physical button were realized.The region of two button sizes is marked respectively in the lower left corner of touch pad induction region and lower right corner
As virtual key region.Touch pad induction region is divided into three areas, i.e. left key area, right button area and coordinate turnover zone, passed through
The algorithm of governor circuit 31 realizes the same function of same physical button.It is equal to left button in left side zonule, on the right cell
The same area right button such as domain, in left side zonule long-press, cursor is moved in coordinate turnover zone, then realizes left button drag function；On the right
Zonule long-press, cursor is moved in coordinate turnover zone, then realizes right button drag function.Touch pad induction zone gathers signal originally
Circuit and physical layer do not change, and are that whole touch pad is sat as coordinate turnover zone, the X mainly read, Y before improvement
Mark information.After the present embodiment removes key circuit, the sensing of whole touch pad is distinguished into three areas, marks the left key area and the right side come
Keypad just do not go read X, Y-coordinate information, and be responsible for read button short-press, the information of long-press, so as to realize physics by
The function of key.Remove left key area and the remaining coordinate turnover zone in right button area then continues to realize original identical function, that is, read light
Target X, Y-coordinate function.
Touch circuitry with virtual key described in the present embodiment, eliminate key circuit and physics of the prior art by
Key, do not changing on the basis of touch pad induction zone gathered circuit and the physical layer of signal originally in the prior art, by that will touch
Left virtual key region, right virtual key region and mobile cursor region, left virtual key region and right virtual key are divided into template sensing
Region is used for the length information for reading button and is sent to governor circuit by sensor circuit, and mobile cursor region is used to read light
Target X, Y-coordinate information and by way of sensor circuit is sent to governor circuit realize the read operation of keypress function.By
In the removal of key circuit, Material Cost and processing cost have been saved, has been reduced because of the production link that key circuit is brought
Fraction defective, reduce using link because repair rate caused by key circuit.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
