[0002] As electric vehicles become more popular, various virtual control buttons of the car are usually integrated on the in-vehicle display screen, such as air conditioning adjustment buttons, sound adjustment buttons, lighting adjustment buttons, etc. The legends of these virtual buttons are usually printed on the back of the glass cover by silk screen printing and illuminated by auxiliary backlight. Since the backlight directly shines on the legend of the virtual button, the light passing through the legend of the virtual button is too dazzling, which seriously affects the driving comfort of the driver.

[0003] Chinese invention patent document CN117351909A discloses 1. A method for displaying a halo background in a vehicle-mounted display interface, characterized in that the display method includes: obtaining a target image displayed on the vehicle-mounted terminal display interface, and extracting a target color of a halo background displayed around the target image based on the color in the target image; determining an initial transparency of the halo background based on the three primary color values ​​corresponding to the target color of the halo background, and judging whether the initial transparency needs to be adjusted based on the three primary color values; if not, determining the initial transparency as the transparency to be determined; if so, determining a coefficient of variation based on the three primary color values ​​corresponding to the target color, and determining the transparency to be determined based on the coefficient of variation and the initial transparency; determining a target transparency based on the color type of the background displayed in the vehicle-mounted terminal display interface and the transparency to be determined, and displaying a halo background of the target color around the target image in the vehicle-mounted terminal display interface with the target transparency. The method of determining the initial transparency of the halo background based on the three primary color values ​​corresponding to the target color of the halo background comprises: determining the gray value corresponding to the target color based on the three primary color values; judging whether the difference between the preset value and the gray value is greater than a preset first transparency threshold; if so, taking the first transparency threshold as the initial transparency; if not, taking the difference as the initial transparency. The display method judges whether the initial transparency needs to be adjusted by the following steps: judging whether the red output value of the three primary color values ​​is greater than the green output value of the three primary color values, and whether the red output value is greater than the blue output value of the three primary color values; if both are yes, judging that the initial transparency needs to be adjusted. The color type of the display background includes dark and light colors; the method of determining the target transparency based on the color type of the display background in the display interface of the vehicle terminal and the transparency to be determined comprises: when the color type of the display background is dark, determining the transparency to be determined as the target transparency; when the color type of the display background is light, determining the difference between the preset value and the transparency to be determined as the target transparency. The method of determining the coefficient of variation based on the three primary color values ​​corresponding to the target color, and determining the transparency to be determined based on the coefficient of variation and the initial transparency, includes: calculating the standard deviation and the three-color average value based on the three primary color values, and determining the quotient between the standard deviation and the three-color average value as the coefficient of variation; judging whether the coefficient of variation is greater than or equal to a preset threshold; if so, determining a second transparency threshold as the transparency to be determined; if not, determining the transparency to be determined based on the second transparency threshold, the initial transparency and the coefficient of variation.The determining of the transparency to be determined based on the second transparency threshold, the initial transparency and the coefficient of variation includes: subtracting the preset threshold from the coefficient of variation to obtain a first value; subtracting the initial transparency from the second transparency threshold to obtain a second value; multiplying the first value by the second value to obtain a third value; and determining the sum of the second transparency threshold and the third value as the transparency to be determined.

[0004] Obviously, this patent sets the transparency of the halo background based on parameters such as the three primary color values ​​and coefficient of variation of the halo color, which cannot solve the problem that the existing virtual buttons are too dazzling. Utility Model Content
