Mobile terminal and control method thereof

Abstract

The embodiment of the invention provides a mobile terminal and a control method thereof, relates to the technical field of terminals, and aims at solving the problems of relatively low key trigger accuracy and reliability of a capacitive sensor in the prior art. The mobile terminal comprises a terminal body and a detection control unit, wherein a pressure-sensitive resistor array is arranged on the inner surface of at least one side wall of the terminal body; the detection control unit is arranged in the terminal and is electrically connected with the pressure-sensitive resistor array; the detection control unit can detect the number, positions and pressure values of pressed points in the pressure-sensitive resistor array, and trigger a specific function of the terminal according to the number, the positions and the pressure values of the pressed points. The mobile terminal can be used for replacing a traditional terminal with mechanical keys on side walls.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a mobile terminal and a control method thereof. Background technique [0002] At present, in order to increase the area of ​​the display area of ​​the mobile terminal, buttons such as power supply, volume control and camera are usually arranged on the side wall of the mobile terminal. In the prior art, the trigger buttons on the side wall of the mobile terminal are usually mechanical buttons. As the number of uses increases, the probability of damage to the buttons is relatively high. , you have to move your finger to the key position to press the key, and the user experience is low. [0003] In order to avoid the above problems, Chinese patents CN103823602A and CN104298392A use capacitive sensors to replace traditional mechanical keys, and trigger the terminal function by sensing the capacitance change of the sensor, avoiding the impact between physical materials, red...

AI Technical Summary

Problems solved by technology

However, since the capacitance value between the two plates of the capacitive sensor is very small, and there is a connecting wire between the sensor and the detection control unit of the terminal, there is a relatively large capacitance in the connecting wire, which causes great interference to the capacitive sensor and makes the The capacitance value of the sensor cannot be accurately determined, so it is difficult to trigger the function of the mobile terminal through the change of the capacitance value, thereby reducing the accuracy and reliability of the key trigger of the mobile terminal
