The attenuation parameters comprise a distance attenuation factor and an angle attenuation factor, wherein the distance attenuation factor can be expressed by alpha, and the angle attenuation factor can be expressed by beta. Because the surface of the infrared touch screen is made of glass, the infrared signal emitted by the transmitting lamp has reflection and diffraction on the infrared touch screen, the infrared voltage value received by the receiving lamp has certain attenuation relative to the infrared signal emitted by the transmitting lamp, and the attenuation parameters can quantify the attenuation of the infrared signal. If the transmitting lamp transmits an infrared signal towards the receiving lamp, the infrared voltage value received by the receiving lamp only has distance attenuation and no angle attenuation, namely, the obtained reference light path voltage value and the reference light path voltage value only have distance attenuation and no angle attenuation; if the transmitting lamp does not transmit infrared signals towards the receiving lamp, the infrared voltage value received by the receiving lamp has not only distance attenuation but also angle attenuation, namely the obtained inclined light path voltage value has both distance attenuation and angle attenuation. The attenuation parameter of each inclined light path voltage value can be determined based on the reference light path voltage value and the reference light path voltage value.

The calculation formula can be expressed as: alpha x ＝(S V0 -S x )/S V0 Wherein S is V0 Is the reference light path voltage value S x For any reference light path voltage value, alpha x Is a distance attenuation factor corresponding to the reference light path voltage value.
The reference light path voltage value corresponds to the inclined light path voltage value one by one, namely the same infrared light path correspondingly comprises a reference light path voltage value and an inclined light path voltage value, the reference light path voltage value of the same infrared light path and the transmission light path of the inclined light path voltage value are the same, and only the difference exists between the reference light path voltage value and the transmission light path of the inclined light path voltage value in the transmitting angle of the infrared signal, so that the distance attenuation factors of the reference light path voltage value and the inclined light path voltage value are equal, and the distance attenuation factor of any reference light path voltage value can be used as the distance attenuation factor of the inclined light path voltage value corresponding to the reference light path voltage value.
For example, according to the above method, the obtained plurality of distance attenuation factors are shown in table 1.

The calculation formula can be expressed as: alpha z ＝(S V0 -S y )/S V0 Wherein S is V0 Is the reference light path voltage value S y For any oblique light path voltage value, alpha z Is a comprehensive attenuation factor corresponding to the voltage value of the inclined light path; the angle attenuation factor can be obtained by the calculation formula: beta x ＝α z -α x ，β x An angle attenuation factor alpha as any inclined light path voltage value z Alpha is the corresponding comprehensive attenuation factor x Is the corresponding distance attenuation factor.
For example, according to the above method, a plurality of angle attenuation factors are obtained as shown in table 2.
| Infrared light path number | L1 | L2 | L3 | L4 | L5 |
| Beta value | 0.05 | 0.055 | 0.07 | 0.10 | 0.12 |

Specifically, if the number of distance attenuation factors or angle attenuation factors is n, the maximum number of infrared light paths that the receiving lamp can receive is 2n+1, and the minimum number of infrared light paths is n+1.
For example, as shown in fig. 2, if the angle attenuation factor is 5, the receiving lamp R9 may receive the infrared signals emitted by the emitting lamps T4, T5, T6, T7, T8, T9, T10, T11, T12, T13 and T14, and the infrared signals emitted by the 11 emitting lamps are simultaneously received by R9, so that R9 may obtain the infrared signals of the corresponding 11 infrared light paths.
