Based on above-mentioned terminal device hardware structure and communications network system, each embodiment of the inventive method is proposed.

Fig. 3 is according to the flow chart of the calibration method of the touch screen of one embodiment of the present of invention, is come with reference to Fig. 3 detailed The calibration method of touch screen according to an embodiment of the invention is described, as shown in figure 3, this method comprises the following steps S301 extremely S303。

S301, when receiving touching signals, actual parameter that the gestures of the trigger collection touching signals is included, this is touched Control signal is the signal received by touching screen.

In one of which embodiment, above-mentioned gesture can be clicked or double-click or long-press, above-mentioned touching signals Can be that touch-key of the user on the screen for clicking on terminal device triggers, the touching signals can be tactile by clicking The signal of hair or the signal by double-clicking triggering, can also be the signal triggered by long-press.

S302, according to the actual parameter and default rule, calculate calibration parameter.

According to the present embodiment example, the calibration method of the touch screen includes sensitivity calibration, therefore, the triggering this touch The actual parameter that the gesture of control signal is included can be pressure sensitivity, and corresponding calibration parameter can be sensitivity calibration ginseng Number.

In this example, above-mentioned default rule can be by user it is actual press screen average pressing dynamics (or Say it is average sensitivity), acquiescence pressing dynamics of the parameter such as average acceleration with the reception touching signals of acquiescence, acquiescence acceleration It is compared etc. parameter, when difference excessive (such as more than 3 grams) of the be averaged pressing dynamics and acquiescence pressing dynamics, can incites somebody to action The pressing dynamics of the acquiescence are updated to average pressing dynamics, and the acceleration of acquiescence is updated into the average acceleration.

In this example, above-mentioned average pressing dynamics can by seek the sensitivity sum averaging of each contact come Obtain.

According to another example of the present embodiment, the calibration method of the touch screen also includes the offset calibration of touch point, therefore, The actual parameter can also be the actual coordinate of touch point, and accordingly calibration parameter can also be the offset calibration of touch-control central point Coordinate.

S303, the parameter for triggering the touching signals is updated to the calibration parameter.

In one of which embodiment, the actual parameter includes the actual coordinate of touch point, and the calibration parameter includes touching Control the offset calibration coordinate of central point.

Wrapped when should receive touching signals, the step of the actual parameter that the gestures of the trigger collection touching signals is included Include:

When receiving touching signals, the actual coordinate of the touch point is gathered in real time, to obtain coordinate sample.

In one of which embodiment, the coordinate sample can be the sample being acquired in units of quantity, also may be used To be the sample gathered in units of the time.When using quantity as unit, such as the actual coordinate of 100 touch points can be made , can also be using the coordinate of all touch points collected within one day as the coordinate sample for the coordinate sample.

According to the actual parameter and default rule, the step of calculating calibration parameter, includes for this:

It is distributed according to the coordinate of each touch point in the coordinate sample, determines practical center coordinate;

It is when the coordinate difference of the practical center coordinate and the default touch-control central point, the practical center coordinate is relative It is defined as the offset calibration coordinate in the offset coordinates of the touch-control center point coordinate.

In one of which embodiment, when the ratio for the point being located in the coordinate sample in predeterminable area is less than default During three threshold values, it is distributed according to the coordinate of each touch point in the coordinate sample, determines practical center coordinate.

In the operating system of terminal device, a piece of effective coverage can be pre-set to each touch key-press, it is effective at this The touch-control detected in region can trigger corresponding button and send touching signals to system, and touch-screen hardware can be received to use by oneself In touch, by some modes, convert data to coordinate, now, coordinate is physical coordinates, i.e. the coordinate of touch-screen, and It is not the coordinate of display device, the coordinate of display device is defined by software, and the physical coordinates of touch-screen are fixed, institutes So that when user's point touching screen, data are fed to the driving of terminal device, then when giving application program by driving, obtained number According to not also being real display device data, for example a point is clicked on, what hardware transmitted is (165,112), at this moment if screen (165,112) point on curtain has click, and this is incorrect, is not really to anticipate because the point of physics is the point sampled The coordinate of display device in justice, after all displaing coordinate determined by system.

Above-mentioned offset calibration coordinate defines on software view, the coordinate and the seat of display device that hardware is transmitted Corresponding relation between mark is corrected.The reason for needing correction, is due to physical coordinates and screen coordinate and mismatches.

Unmatched reason has two aspects:

First, 1 unit of physical coordinates and 1 unit of screen coordinate are simultaneously unequal, due to 1 unit of screen coordinate A usually pixel, and 1 unit of physical coordinates is not 1 pixel.

Second, it is assumed that we are defined as the upper left corner of screen (0,0), then the physical coordinates in the upper left corner of touch-screen are simultaneously It is not (0,0) that this point can be determined by the physical layer sampled data after user's click push button.

In other embodiments, above-mentioned parameter update module is mainly used for calibrating, and its alignment is mainly by following Step (1) and step (2) are completed:

(1), offset more in the coefficient of dilatation of y-axis and the coordinate system according to coefficient of dilatation, touch point of the touch point in x-axis The new calibration parameter.

Wherein, physics sample coordinate and the corresponding relation of screen pixels coordinate, that is, coefficient of dilatation, i.e. unit physics are adopted Sample data represent several unit screen pixel datas, and x coordinate and y-coordinate respectively have a coefficient of dilatation, be denoted as respectively:XS and yS. Computational methods are very simple, in order to accurate, can sample four points on screen, respectively A, B, C, D, be removed by line segment sidewards The data line segment sampled with physics, has obtained x coefficient of dilatation.Y coefficient of dilatation can also similarly be obtained.

(2), the origin where the origin and on-screen display system according to where hardware system determines coordinate system Skew.

Wherein, the skew relative to screen pixels coordinate of physical coordinates, coefficient of dilatation is only calculated not calculating skew In the case of, it is assumed that point A of the user on screen is clicked on, and by changing physics sampled data, that is, is multiplied by coefficient of dilatation, is sent out Existing, the data after calibration are not point A, and reason is exactly to be adopted because of the physics that the reason for being offset, and being offset is touch-screen Sample data, it is not in the upper left corner (0,0), but some positive number pair, the data sampled will not be origins, here it is skew to produce The reason for raw, so, after coefficient of dilatation was calculated, for example screen A is clicked on, the data sampled are A ', if above-mentioned meter The coefficient of dilatation calculated is 0.78 and 0.67 respectively, then physical coordinates be converted into screen coordinate after be (A 'x* 0.78, A 'y* 0.67), wherein A 'xRepresent A points ' in the coordinate of x-axis, A 'yCoordinates of the point A ' in y-axis is represented, although now we have obtained physics Screen coordinate corresponding to coordinate, but screen coordinate and the screen coordinate where point A be not in a coordinate system, i.e. origin now Difference, so we will subtract a coordinate system skew, it is assumed that be x ' and y respectively ', then two coordinates make the difference and have just obtained x ' And y '.

Above-mentioned steps S303 be further according to touch point the coefficient of dilatation of x-axis, touch point y-axis coefficient of dilatation and The coordinate system skew updates the calibration parameter.The embodiment according to four parameters above, and x-axis coefficient of dilatation xS, Coefficient of dilatation yS in y-axis, the relatively x ' in x-axis, the coordinate points after the skew y ' of y-axis can be calibrated, if screen The coordinate upper left corner is (0,0), and when we click on screen, now we obtain physics x and y data from driving there, are multiplied by respectively XS and yS obtains relative screen coordinate, subtracts the x ' and y ' of translation, you can obtained current screen coordinate.
