In an alternative embodiment, referring to fig. 3, the processing the data to be displayed to obtain the information to be displayed further includes:
and step 111, acquiring the proportion of at least one color in the data to be displayed.
In this step, the data to be displayed includes at least one color data, and the proportion of the area of the LED screen that each color needs to occupy when displaying is calculated according to each color data.
And step 112, determining background information according to the proportion of the at least one color.
In this step, when the proportion of one color is the highest, the related information corresponding to the color with the highest proportion is used to determine the background information, and preferably, the background information is determined at the position information corresponding to the color with the highest proportion.
And 120, controlling all or part of the first LED lamp beads of the LED screen for displaying the background information to be closed according to the background information.
In the step, the position of the LED screen for displaying the background information is calculated according to the background information and the size of the LED screen, and the LED screen at the position for displaying the background information is partially or completely closed corresponding to the first LED lamp bead. Preferably, the first LED lamp beads on the position displaying the background information are correspondingly and completely closed.
And step 130, controlling all or part of second LED lamp beads of the display content information of the LED screen to be turned on according to the content information.
In the step, the position of the LED screen for displaying the content information is calculated according to the content information and the size of the LED screen, and the LED screen at the position for displaying the content information is partially or completely opened corresponding to the second LED lamp bead. Preferably, the second LED lamp beads on the position for displaying the content information are all correspondingly turned on.
In an alternative embodiment, referring to fig. 4, the content information includes a content area and a content color, and controlling all or part of the second LED beads of the display content information of the LED screen to be turned on according to the content information further includes:
and 131, controlling all or part of second LED lamp beads of the display content information of the LED screen to be turned on according to the content area.
In this step, the content area is the position, shape and size of the main content to be displayed, and the position for displaying the content information is calculated according to the position and size of the main content to be displayed and the size of the LED screen.
And 132, controlling all or part of second LED lamp beads of the display content information of the LED screen to display target colors according to the content colors.
In the step, the content color is the color of each area of the main content to be displayed, and the second LED lamp beads are controlled to display the corresponding color according to the position and the size of the main content to be displayed and the size of the LED screen.
