1. A method of controlling a display by a headset with inline control, comprising:
detecting whether a headset jack of the display is plugged with the headset;
after the headset jack of the display is determined to be plugged with the headset, inputting a detection bias voltage to the headset, and monitoring a feedback signal of the detection bias voltage by monitoring the feedback signal of the detection bias voltage in voltage or frequency level;
in response to detecting a change in the feedback signal of the detection bias voltage, identifying a user's control instruction to the display using the headset according to a control signal sent by the headset; and
controlling the display to perform a corresponding display operation according to the control instruction;
wherein identifying a user's control instruction to the display using the headset with inline control according to a control signal sent by the headset with inline control comprises:
determining that the headset is a headset for a first system in response to detecting the change in the feedback signal of the detection bias voltage is only a voltage change; and
determining that the headset is a headset for a second system in response to detecting the change in the feedback signal of the detection bias voltage comprises a frequency change;
wherein identifying a user's control instruction to the display using the headset according to a control signal sent by the headset comprises: when the headset is determined to be the headset for the second system, monitoring the feedback signal of the detection bias voltage in the frequency level, and determining the control instruction comprises: determining that the user triggered a third button in response to detecting a frequency change and detecting changes in both voltages output from a first switch and a second switch of the headset for the second system.
