Abstract

Disclosed are a method of controlling a display by a headset with inline control, and related devices. The method includes: detecting whether an 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; 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.

First claim

The invention claimed is:

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.

2. The method according to claim 1 , 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 first system, determining the control instruction comprises:
determining that the user triggered a first button in response to determining that the voltage output from a first switch of the headset for the first system has changed;
determining that the user triggered a second button in response to determining that the voltage output from a second switch of the headset for the first system has changed; and
determining that the user triggered a third button in response to determining that both the voltages output from the first switch and the second switch have changed.

3. The method according to claim 2 , wherein controlling the display to perform a corresponding display operation according to the control instruction comprises:
controlling the display to increase a volume or increase a display brightness in response to determining that the control instruction corresponds to the first button;
controlling the display to lower the volume or reduce the display brightness in response to determining that the control instruction corresponds to the second button; and
controlling the display to perform a menu display, turn-on or turn-off operation based on a current display state of the display, in response to determining that the control instruction corresponds to the third button.

4. The method according to claim 3 , wherein controlling the display to perform a menu display, turn-on or turn-off operation based on a current display state of the display, in response to determining that the control instruction corresponds to the answer button comprises:
controlling the display to perform a menu display or turn-off operation if a current display state of the display is an on state;
controlling the display to perform a turn-on operation if the current display state of the display is an off state; and
controlling the display to perform a turn-off operation if the current display state of the display is a menu display state.

5. The method according to claim 1 , 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 further comprises:
determining that the user triggered a first button in response to detecting a first frequency; and
determining that the user triggered a second button in response to detecting a second frequency, wherein the first frequency is greater than the second frequency.

6. A control circuit board of a display, comprising a memory configured to store a computer readable program, and a processor, wherein the processor is configured to read the computer-readable program to perform following method steps:
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 the processor is configured to identify 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, by:
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 the processor is configured to monitor the feedback signal of the detection bias voltage in the frequency level, and determine the control instruction when the headset is determined to be the headset for the second system, by: 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.

7. The control circuit board according to claim 6 , wherein the processor is configured to determine the control instruction when the headset is determined to be the headset for the first system, by:
determining that the user triggered a first button in response to determining that the voltage output from a first switch of the headset for the first system has changed;
determining that the user triggered a second button in response to determining that the voltage output from a second switch of the headset for the first system has changed; and
determining that the user triggered a third button in response to determining that both the voltages output from the first switch and the second switch have changed.

8. The method according to claim 7 , wherein the processor is configured to control the display to perform a corresponding display operation according to the control instruction, by:
controlling the display to increase a volume or increase a display brightness in response to determining that the control instruction corresponds to the first button
