The preset triggering mode comprises clockwise rotation triggering and anticlockwise rotation triggering, wherein the clockwise rotation triggering can refer to that the triggering state of the knob contact passes through the state 2, the state 3, the state 4, the state 5, the state 6, the state 7 and the state 8 from the state 1 in sequence and then returns to the state 1; a counter-clockwise rotation trigger may refer to a trigger state of the knob contact passing from state 1, through state 8, state 7, state 6, state 5, state 4, state 3, state 2, and back to state 1.
For example, after the display panel is started, the knob rotates once, after a triggering action is performed, the knob 23 stays in a state 3 after passing through the state 2, and the middle crossing state 2, the control module of the display device determines that clockwise rotation triggering is performed according to the state 2 and the state 3, that is, the rotation direction of the current knob 23 is determined to be clockwise rotation, and the initial triggering state of the knob 23 is a state 1, that is, the state 1 is the initial position of the knob; or, the knob 23 stays in the state 3 after passing through the state 4, the middle crossing state 4, and the control module of the display device determines that the rotation is triggered by the counterclockwise rotation according to the state 4 and the state 3, namely, determines that the rotation direction of the current knob is rotated counterclockwise, and the initial triggering state of the knob 23 is the state 5, namely, the state 5 is the initial position of the knob.
For example, after the display panel is started, the knob rotates once, after a triggering action is performed, the knob 23 stays in a state 7 after passing through the state 6, and the middle crossing state 6, the control module of the display device determines that clockwise rotation triggering is performed according to the state 6 and the state 7, that is, determines that the rotation direction of the current knob is clockwise rotation, and the initial triggering state of the knob 23 is a state 5, that is, the state 5 is the initial position of the knob; or, the knob 23 stays in the state 7 after passing through the state 8, the middle crossing state 8, the control module of the display device determines that the rotation direction of the current knob is counterclockwise rotation according to the state 8 and the state 7, and the initial triggering state of the knob 23 is state 1, namely, the state 1 is the initial position of the knob.
Every time a trigger action occurs on the knob 23, the switch is switched from one final trigger state to an adjacent final trigger state, and as two intermediate contacts are added in the process of switching one trigger state, the original two contacts are added to 4 contacts. And then, through the change of the angle of the knob, the trigger states of the knob contacts are changed from 4 to 8, so that an intermediate trigger state, such as state 2, state 4, state 6 and state 8, is added in the switching of two adjacent final trigger states, and the number of intermediate trigger states of the knob in one trigger action is increased.
After one triggering action, the control module of the display device can judge the rotation direction of the knob through detecting the intermediate triggering state and the final triggering state of the knob, so as to determine the initial triggering state of the knob, namely the initial position of the knob. Through the driving mode, the first starting up can be realized, and the rotating direction of the knob can be judged, so that the problem that the knob is firstly rotated to lose efficacy after the display panel is started up is solved, and the detection efficiency of the display panel and the knob gear and the accuracy of feedback are improved.
