[0038] Technical effects and advantages

[0039] 1. The membrane button 200 of the operation panel structure is adhered to the transparent PC surface shell through the backing adhesive, which can prevent external dust and water vapor from entering the interior of the panel to achieve dust and water proof effect;

[0040] 2. The operation panel structure can be equipped with lights of different colors to provide a prompt effect. Different areas are set with LEDs of different colors. Different states correspond to different colors of LEDs, which makes it easier for operators to distinguish in dim light.

[0041] 3. The button unit 201 is white when not pressed, changes color when pressed, changes to another color when long pressed, and returns to the original color when canceled;

[0042] 4. The button unit 201 and the indicator light are isolated from the internal and external light by the indicator light shielding column 403, so that the light will not bleed into each other;

[0043] 5. The switch of the LED light is automatically adjusted according to the intensity of the external ambient light. When the light is dark, the LED will automatically turn on, making it clearly visible in a dark environment;

[0044] 6. Simple structure, low processing cost, suitable for various forms of operation panels.

[0045] Specifically, Figure 1 As shown, it is a decomposition explosion diagram of the operation panel structure visible at night. The operation panel structure in the embodiment is simple in design. When the light in the environment changes and reaches the value of the photoresistor, the voltage of the photoresistor changes and transmits the signal to the main control MCU, and the main control MCU turns on or off the LED light. When the state of the key unit 201 changes during use, the corresponding key unit 201 will also display different colors. When the key unit 201 is not pressed, the overall light is cold white. When the key unit 201 is pressed, the wireframe and characters in the key area will turn green. When the key unit 201 is pressed for a long time, the key light turns blue. When the key unit 201 is pressed again, the corresponding function cancels the color and returns to cold white. In this way, the user in a dark environment is reminded of the current use status of the device and the key functions corresponding to different colors through the changes in different colors. The red operator serves as a warning to the operator.
