Embodiment 1
[0032] refer to figure 2 , which shows a flow chart of a method for preventing false touches according to Embodiment 1 of the present invention, which may specifically include the following steps:
[0033] Step 201, acquiring the variation of the standing wave ratio of the at least one first antenna and the at least one second antenna at a specified frequency point.
[0034] In the embodiment of the present invention, when the user holds the mobile terminal, the standing wave ratio of the antenna in the mobile terminal will change. When the user's palm touches the first screen 11 in the double-sided screen 10, the first screen The standing wave ratio of the blocked first antenna 111 on the 11 will change greatly. When the user's palm touches the second screen 12 in the double-sided screen 10, the blocked second The standing wave ratio of the antenna 121 will change greatly.
[0035] The full name of the standing wave ratio is the voltage standing wave ratio. Where the phase...
Embodiment 2
[0047] refer to image 3 , which shows a flow chart of a method for preventing false touches according to Embodiment 2 of the present invention, which may specifically include the following steps:
[0048] Step 301, acquiring the current standing wave ratio of the at least one first antenna and the at least one second antenna at a specified frequency point.
[0049] In the embodiment of the present invention, a standing wave ratio detection circuit is provided at the position corresponding to each antenna to detect the standing wave ratio of the corresponding antenna, and a double directional coupler, forward Detection circuit, reverse detection circuit and voltage comparison circuit, the dual directional coupler is used to couple the radio frequency signal superimposed on the antenna, the forward detection circuit is used to detect the maximum voltage value of the coupled radio frequency signal, and the reverse detection circuit is used to detect the coupling After the minim...
Embodiment 3
[0074] refer to Figure 5 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.
[0075] The mobile terminal 500 has a double-sided screen 10, the double-sided screen 10 includes a first screen 11 and a second screen 12 oppositely arranged, the first screen 11 is provided with at least one first antenna 111, the first At least one second antenna 121 is provided on the second screen 12, and the first antenna 111 is set corresponding to the position of the second antenna 121, and the mobile terminal 500 includes:
[0076] A standing wave ratio variation acquisition module 501, configured to acquire the variation of the standing wave ratio of the at least one first antenna and the at least one second antenna at a specified frequency point;
[0077] An invalid touch area determination module 502, configured to determine an invalid touch area in the double-sided screen according to the variation of the standing wave ratio of th...
