Embodiment

Below in conjunction with drawings and Examples, the application's embodiment is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.

The schematic flow sheet of a kind of distribution determination method embodiment that Fig. 1 provides for the application.As shown in Figure 1, the present embodiment comprises:

110, obtain the capacitance profile of a plurality of capacitance type sensors under at least two driving voltages on a display screen.

For instance, the distribution determining device that the application provides is as the executive agent of the present embodiment, with execution 110～120.Particularly, described distribution determining device can software and/or the form of hardware be arranged in display device, alternatively, described display screen is also arranged in described subscriber equipment, or described distribution apparatus itself is exactly the display device that is provided with described display screen.

In the present embodiment, described at least two driving voltages refer at least two driving voltages that magnitude of voltage is different.

In the present embodiment, on described display screen, a plurality of capacitance type sensors can be arranged on the capacitance type sensor in the capacitive touch screen on described display screen, or, the capacitance type sensor of other form.Under the effect of driving voltage, when a conductor (as beholder) near as described in during display screen, the electric field of this conductor can be to exerting an influence with the capacitance of the nearer capacitance type sensor of this conductor distance on described display screen, conventionally, under the effect of identical driving voltage, larger with the capacitance of the nearer capacitance type sensor of the distance of this conductor.

Described capacitive touch screen comprises respectively from top to bottom: protective seam (Protective cover), electrode style layer (Electrode pattern layer), glass substrate (Glass substrate); wherein; electrode style layer is comprised of transparent electrode layer (Transparent electrode layer) X and transparent electrode layer Y conventionally; under the effect of driving voltage, the electrode in transparent electrode layer X and the electrode in transparent electrode layer Y can form a capacitance type sensor.

In the present embodiment, described capacitance profile refers to the distribution of capacitance, not only relevant with the capacitance of described a plurality of capacitance type sensors, relevant with the distribution of described a plurality of capacitance type sensors in described touch-screen.

120, at least according to the capacitance profile under described at least two driving voltages, determine the distribution of at least one conductor of described display screen the place ahead.

Conventionally, under the effect of different driving voltages, capacitance type sensor is suitable for surveying the electric field of different distance; Driving voltage is larger, and capacitance type sensor is suitable for surveying more remote electric field.

Alternatively, described at least two driving voltages are corresponding one by one with space, at least two, the place ahead of described display screen.Particularly, under the effect of each driving voltage, the capacitance profile of described a plurality of capacitance type sensors can more accurately be reflected to the distribution of electric field in the space that this driving voltage is corresponding.Wherein, because the magnitude of voltage of described at least two driving voltages is different, the distance of described at least two spaces and described touch-screen, distance range, conventionally also different in other words.Alternatively, the distance range of described at least two spaces and described touch-screen can be overlapping, or not overlapping, the present embodiment is not construed as limiting this.

For instance, the space that a driving voltage is corresponding and the distance range of described display screen are [5 centimetres, 10 centimetres], and the space that another driving voltage is corresponding and the distance range of described display screen are [20 centimetres, 30 centimetres]; Again for instance, the space that a driving voltage is corresponding and the distance range of demonstration are [5 centimetres, 15 centimetres], and the space that another driving voltage is corresponding and the distance range of described demonstration are [12 centimetres, 30 centimetres].

The present embodiment is by adjusting the driving voltage of a plurality of capacitance type sensors on display screen, Electric Field Distribution in the space of described display screen the place ahead different distance is carried out to demixing scan, thereby determine the distribution of display screen the place ahead conductor, the scheme that provides a kind of definite display screen the place ahead conductor to distribute, can be for determining display screen the place ahead beholder's distribution, and with capacitance type sensor, detect, cost and system complexity are all lower.

The method of the present embodiment is described further below by some optional implementations.

The present embodiment 110 in, can successively with each driving voltage in described at least two driving voltages, encourage a plurality of capacitance type sensors in described touch-screen in sequence, particularly, the excitation order of described at least two driving voltages can be arbitrarily, or, according to the adjustment strategy of described display screen environment set driving voltage of living in, or, according to the capacitance profile obtaining before, adjust driving voltage next time.

In a kind of optional implementation, described in obtain the capacitance profile of a plurality of capacitance type sensors under at least two driving voltages on a display screen, comprising:

Obtain first capacitance profile of a plurality of the first capacitance type sensors under one first driving voltage on described display screen.

Alternatively, obtaining after described the first capacitance profile, can determine driving voltage next time according to this first capacitance profile.

A kind of possible scene is, described in obtain the capacitance profile of a plurality of capacitance type sensors under at least two driving voltages on a display screen, also comprise:

In response to the maximum capacity region in described the first capacitance profile, there is flat-top electric capacity crest, obtain second capacitance profile of a plurality of the second capacitance type sensors under one second driving voltage lower than described the first driving voltage on described display screen.

It should be noted that, under the driving voltage effect of same magnitude of voltage, the capacitance profile of different capacitance type sensors may reflect the Electric Field Distribution of different spaces.Space under the Electric Field Distribution reflecting by this capacitance profile of space representation corresponding to capacitance profile below.

Conventionally, when there is at least one conductor in the middle of space corresponding to the first capacitance profile and described display screen, because this at least one conductor is nearer than described space with the distance of described display screen, therefore, the electric field of this at least one conductor can exceed the detectivity of the capacitance type sensor under the first driving voltage effect, and the electric field formation of surveying in scope corresponding with the electric field of this at least one conductor in described space is stopped, therefore, in described the first capacitance profile, can present a maximum capacity region that has a flat-top electric capacity crest.Correspondingly, in order to survey better this at least one conductor, can reduce driving voltage.

Fig. 2 A is the schematic diagram of a kind of capacitance profile under scene for this reason.The floor map that the upper figure of Fig. 2 A is capacitance profile, black net region is background, is equivalent to capacitance lower than the region of lower limit, the more shallow expression capacitance of color is higher; Figure below of Fig. 2 A is the two-dimensional coordinate figure of capacitance, and transverse axis represents the dimension coordinate of capacitance type sensor on display screen, and the longitudinal axis represents capacitance; Fig. 2 B～2G is also similarly, is not repeating.As shown in Figure 2 A, in the capacitance profile shown in upper figure, white portion is maximum capacity region, and accordingly, the region that in the coordinate diagram shown in figure below, horizontal line is corresponding is maximum capacity region, from figure below, can find out, maximum capacity region exists flat-top electric capacity crest.It should be noted that, humanoid only in order to signal in the upper figure of Fig. 2 A, and non-limiting described conductor is people, Fig. 2 B～2G is also similar.

Fig. 2 B is the schematic diagram of another capacitance profile under scene for this reason.As shown in Figure 2 B, in the capacitance profile shown in upper figure, white portion is maximum capacity region, and accordingly, the region that in the coordinate diagram shown in figure below, horizontal line is corresponding is maximum capacity region, from figure below, can find out, maximum capacity region exists flat-top electric capacity crest.

Wherein, it can be pre-set encouraging which capacitance type sensor in described touch-screen at every turn, and particularly, described a plurality of the first capacitance type sensors can be identical with described the second capacitance type sensor, or, difference.Or, encourage which capacitance type sensor on described display screen to determine with reference to the capacitance profile obtaining after last time excitation at every turn.

Alternatively, described method also comprises:

The distribution on described display screen according to described the first capacitance profile and described a plurality of the first capacitance type sensor, determines described a plurality of the second capacitance type sensor.

Particularly, the distribution of described a plurality of the first capacitance type sensors on described display screen determined to a great extent, and space corresponding to described the first capacitance profile projects the scope of described display screen place plane.For instance, when described the first capacitance profile reflects, when in spatial dimension corresponding to the right side area of described display screen, electric field is stronger, when determining described a plurality of the second capacitance type sensor, can select the more capacitance type sensor that is positioned at right side area on described display screen, again with a plurality of the second capacitance type sensors described in the second activation voltage, thereby can obtain reflecting better the second capacitance profile of Electric Field Distribution in space corresponding to right side area on described display screen.

Particularly, above-mentioned definite described a plurality of the second capacitance type sensors may be identical with described a plurality of the first capacitance type sensors, or, difference.

Conventionally, when there is not conductor in space corresponding to the first capacitance profile, Electric Field Distribution in this space approaches the Electric Field Distribution in free space, further, if there is not conductor between described space and described display screen yet, do not have stopping of the Electric Field Distribution surveyed in described space, correspondingly, in described the first capacitance profile, capacitance profile is more even.Correspondingly, under this scene, for detecting conductor better, can improve driving voltage, with the farther space of display screen described in detection range.

Fig. 2 C is the schematic diagram of a kind of capacitance profile under scene for this reason.As shown in Figure 2 C, the capacitance profile shown in upper figure is more even, accordingly, and almost not fluctuation of capacitance in the coordinate diagram shown in figure below.

Wherein, which capacitance type sensor in the described touch-screen of described each excitation can be pre-set, and particularly, described a plurality of the first capacitance type sensors can be identical with described a plurality of the 3rd capacitance type sensors, or, difference.Or, encourage which capacitance type sensor on described display screen to determine with reference to the capacitance profile obtaining after last time excitation at every turn.
