the driving circuit obtains touch information according to the induction signal and controls the on-off, color, brightness and/or image display of the display component according to the touch information.
Specifically, when a finger of a user touches the first conductive unit 11, the first conductive unit 11 transmits electrostatic charges generated by the finger of the user to the surface of the display device 2 through the connecting member 13 and the second conductive unit 12, the touch electrode 22 of the display device 2 senses a capacitance change to obtain a sensing signal, and sends the sensing signal to the driving circuit, and the driving circuit obtains touch information according to the sensing signal, where the touch information may be a current touch position, that is, display information corresponding to the touch position, and thus, the driving circuit may control the display of an on/off switch, a color, a brightness, and/or an image of the display device 2.
For example, when the control component 1 is a knob, the first conductive unit 11 is an electroplating ring, the connecting member 13 is a spring, the second conductive unit 12 is a conductive plate, and the driving circuit is a driving chip, when a finger contacts the electroplating ring at the edge of the knob, the electroplating ring connects the conductive plate through the spring to transmit electrostatic charges of the finger to the surface of the display component 2, the touch electrode 22 of the display component 2 generates an induction signal and transmits the induction signal to the driving chip, the driving chip can calculate a corresponding touch position according to the induction signal and acquire display information such as a displayed image and a displayed color according to the touch position, and the driving chip can control the display component 2 to be turned on and display the corresponding image and color, and further transmit the display information to the surface of the knob away from the display component 2 for display. For example, when the display device displays and controls the temperature change, if a finger touches the plating ring, the display device 2 can display a corresponding temperature value and a color through the control of the driving chip in the display device 2, and the color can be displayed around the temperature value. For example, at 16 degrees celsius, the color displayed around the temperature value is white.
When the knob rotates, electroplate the circle, the spring changes with the relative display module 2's of conducting strip position, it transmits the static charge that user's finger produced to display module 2's surface to electroplate the circle through spring and conducting strip, the touch-control electrode 22 that display module 2 is different senses the capacitance variation and obtains sensing signal, and transmit sensing signal for driver chip, driver chip can calculate according to sensing signal and obtain corresponding touch-control position, and acquire display information according to the touch-control position, image and colour that so time required to show etc., the change of image and colour on the driver chip can control display module 2, and then transmit to the knob and keep away from display module 2 on the surface and show. For example, when the display device displays and controls the temperature change, when the knob is rotated clockwise, the temperature is increased, the increase of the temperature value on the display component 2 can be controlled by the driving chip, and the corresponding color is displayed, the color can be displayed around the temperature data, when the knob is rotated clockwise, the value displayed by the display component is controlled by the driving chip to be increased, and the color displayed around the value is changed from white to red, so that the displayed value and the color can be transmitted to the surface of the knob away from the display component 2 to be displayed. However, when the knob is rotated counterclockwise, in order to decrease the temperature, the driving chip controls the temperature value on the display component 2 to decrease and display the corresponding color, and the color can be displayed around the temperature data, and when the knob is rotated counterclockwise, the driving chip controls the value displayed on the display component to decrease and the color displayed around the value becomes blue, so that the displayed value and the color can be transmitted to the surface of the knob away from the display component 2 to be displayed. It should be noted that the images and colors displayed in the present embodiment are only exemplary, and are not intended to limit the present invention. .
It can be understood by those skilled in the art that in the embodiment of the present invention, the shape of the aperture is not limited, the on-off control logic of the aperture and the knob is not limited, and the color type and dynamic effect of the aperture are not limited.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
