[0050] The light colors of the above-mentioned backlight circuits can be the same color or different colors. Specifically, the constituent materials of the backlight circuits can be selected according to usage requirements to achieve the selection of light color.

[0051] In one embodiment, the touch control circuit further includes:

[0052] The transparent protective cover has a plurality of via holes, which are arranged above the touch key circuit so that each touch key can extend out of the surface of the transparent protective cover through the corresponding via holes. The identifiers for distinguishing each touch key are printed around each via hole on the transparent protective cover.

[0082] The backlight circuit corresponding to the pressed touch key is driven to light up with the maximum brightness value, so that the touch circuit can work in the best performance state.

[0083] The control circuit is configured to drive the backlight circuit corresponding to the pressed touch key to light up with a preset brightness value when receiving the power supply signal of the energy storage unit, and the preset brightness value is less than the maximum brightness value.

[0084] The preset brightness value may be any brightness value less than the maximum brightness value, such as a 50% brightness value and a 70% brightness value. Setting the preset brightness value can reduce energy consumption and extend the service life of the touch circuit.

[0085] A switch can be set on the path between the power supply and the display circuit. The switch can be configured to connect to a current-limiting resistor with a smaller resistance value when receiving a power supply signal from an external power supply, thereby ensuring that the display circuit at this time obtains a voltage value with optimal display performance; when the control circuit is configured to connect to a current-limiting resistor with a larger resistance value when receiving a power supply signal from an energy storage unit, thereby ensuring that the display circuit at this time obtains a smaller voltage value, and drives the backlight circuit corresponding to the pressed touch button to light up with a preset brightness value.

[0088] A first end of the board-to-board connector is connected to the display circuit, and a second end of the board-to-board connector is connected to the control circuit.

[0089] Using board-to-board connectors can increase the design freedom of touch circuit layout and wiring, and can also reduce the stress of solder joints to prevent solder cracking.

[0090] In one embodiment, the display circuit is an LCD black and white screen.

[0091] The size of the LCD (Liquid Crystal Display) black and white screen can be selected according to actual needs. In one embodiment, the size of the LCD black and white screen can be 2.0 inches, 3.5 inches, or other sizes. It should be noted that in order to ensure that the backlight circuit can be pressed correctly and driven to light up, when selecting LCD black and white screens of different sizes, the actual sizes of the touch button circuit, display circuit, and control circuit need to be designed according to the size.

[0092] When the above-mentioned backlight circuit emits non-white light, the backlight circuit and the LCD black and white screen can be intuitively distinguished by the light color, avoiding visual interference caused by the same light color of the display circuit and the backlight circuit, thereby improving the prompt effect of the backlight circuit.
