In the embodiment, when the contact is in oblique contact with the touch substrate and the oblique contact angle is larger than a preset threshold, determining the contact specification according to the contact material; when the contact is in vertical contact or inclined contact with the touch substrate and the inclined contact angle is smaller than a preset threshold, the contact specification is determined according to the contact parameters or the contact materials, and the accuracy of the acquired contact specification is ensured.
In an exemplary embodiment, determining the contact material according to the elastic wave signal includes: acquiring signal characteristics of the elastic wave signal, wherein the signal characteristics comprise: a duty cycle of the frequency; and identifying the contact material according to the signal characteristics. Because the contact of different materials contacts with the touch screen, there is the difference in the signal characteristics of the elastic wave signals acquired by the elastic wave sensor, the embodiment utilizes the difference to realize the identification of the contact materials, and the accuracy of the contact material identification is improved.
In an exemplary embodiment, the method for obtaining the duty ratio coefficient of the frequency of the elastic wave signal may include: determining a duty ratio coefficient of a specified frequency band or a specified frequency point based on a ratio of an amplitude parameter of an elastic wave signal serving as a frequency domain signal on the specified frequency band or the specified frequency point to a sum of amplitudes of the elastic wave signal in a full frequency band; the amplitude parameter may be: amplitude, amplitude sum, maximum amplitude, average amplitude, and difference between maximum amplitude and minimum amplitude.

In an exemplary embodiment, determining, according to the obtained signal characteristics, a probability that a contact material to be identified is the preset contact material includes: comparing the obtained signal characteristics with signal characteristics corresponding to each preset contact material, and determining the probability of the contact material to be identified as the preset contact material according to the similarity obtained by comparison; or inputting the acquired signal characteristics into an identification model of the contact material, and determining the probability of the contact material to be identified as each preset contact material according to the identification result of the identification model, wherein the identification model is obtained by training according to signal characteristic sample data corresponding to all preset contact materials.

Under different contact modes, the pressure born by the touch substrate is different, the deformation of the touch substrate is different, and further, the generated elastic wave signals are different, for example, when a contact is knocking the touch substrate, namely, the contact is vertically contacted with the touch substrate, the pressure born by the touch substrate is larger, the force can inhibit the rebound of the touch substrate, so that the vibration amplitude of the touch substrate is larger and the vibration frequency is smaller in the vertical contact process, and therefore, the elastic wave signals are also larger in amplitude and smaller in frequency; when the contact is obliquely knocked on the touch substrate, namely the contact is obliquely contacted with the touch substrate, the pressure born by the touch substrate is reduced, the rebound influence of the force on the touch substrate is also reduced, the vibration amplitude of the touch substrate is smaller, the vibration frequency is larger, and therefore the elastic wave signal is also smaller in amplitude and larger in frequency in the oblique contact process. According to the embodiment, the characteristics that the elastic wave signals generated in the first contact mode and the second contact mode have different signal characteristics are utilized, the signal characteristics of the elastic wave signals generated through contact are compared with the signal characteristics of the elastic wave signals corresponding to the first contact mode and the second contact mode, and the contact mode can be judged according to the comparison result.

In this embodiment, the first specification contact and the second specification contact may be divided according to the thickness of the contacts, where the contact range value corresponding to the thick contact is greater than the contact range value corresponding to the thin contact. In this embodiment, when the contact parameter is located outside the contact range value corresponding to the contact material determined according to the elastic wave signal, it is indicated that the contact specification determined according to the contact parameter and the contact specification determined according to the contact material are inconsistent, if the contact mode is determined to be the first contact mode according to the elastic wave signal at this time, the contact specification determined by the contact material is taken as the finally output contact specification, and at this time, the contact mode of the contact and the touch substrate is determined to be the first contact mode.
In an exemplary embodiment, determining a contact mode of the contact with the touch substrate according to the elastic wave signal and the contact parameter further includes: and when the contact parameter belongs to a preset contact range value of the first specification or a contact range value of the second specification, and the contact parameter is positioned in a contact range value corresponding to the contact material determined according to the elastic wave signal, determining that the contact mode of the contact and the touch substrate is a second contact mode. In this embodiment, when the contact parameter is located within the contact range value corresponding to the contact material determined according to the elastic wave signal, it is indicated that the contact specification determined according to the contact parameter is consistent with the contact specification determined according to the contact material, and the contact specification may be determined according to the contact material or the contact specification may be determined according to the contact parameter, where the contact mode of the contact and the touch substrate is determined as the second contact mode.
In an exemplary embodiment, determining a contact mode of the contact with the touch substrate according to the elastic wave signal and the contact parameter further includes:
when the contact parameter is between a preset first specification contact range value and a second specification contact range value or exceeds the second specification contact range value, judging whether the distance between the contact parameter and a contact range value corresponding to a contact material determined according to the elastic wave signal is smaller than a preset value, and if so, determining that the contact mode of the contact and the touch substrate is a first contact mode; if not, the contact mode of the contact head and the touch substrate is determined to be a first contact mode or a second contact mode by default. In this embodiment, when the contact specification cannot be determined by the contact parameter, if the contact parameter is close to the contact range value corresponding to the contact material determined according to the elastic wave signal, the contact specification determined by the contact material is used as the final output contact specification, and at this time, the contact mode of the contact and the touch substrate is determined as the first contact mode. The preset value is equivalent to a tolerance degree for erroneous judgment, and the larger the preset value is, the higher the tolerance is, and the greater the possibility of errors is. The preset value may be determined based on empirical or experimental data.
In an exemplary embodiment, determining a contact mode of the contact with the touch substrate according to the elastic wave signal and the contact parameter further includes: and when the contact parameter is smaller than a preset contact range value of the first specification contact, judging that the contact is invalid. In this embodiment, when the contact parameter is smaller than the preset contact range value of the first specification contact, it is indicated that the contact area of the contact with the touch substrate is too small, and the contact is determined as an ineffective contact.
