For the sake of better understanding of the present embodiment, the following describes the image display method of the present embodiment in detail with reference to fig. 7.
As shown in fig. 7, an image display method includes:
s701, a screen printing instruction is given;
and the embedded arm end receives the screen-printing instruction and analyzes the screen-printing instruction to obtain image position information and mouse position information.

In summary, in the conventional hardware screen printing, the PC directly sends the relevant adjustment parameters to the receiving card via the sending card, and then the receiving card draws an image according to the received relevant adjustment parameters to generate image data, and then sends the image data to the LED display screen for display. However, in the existing hardware screen printing method, the receiving card is required to generate image data according to relevant adjusting parameters and send the image data to the LED display screen for display, and the requirement on the receiving card is high, so that hardware screen printing can not be realized on all types of receiving cards, and the operating efficiency of the whole hardware screen printing is very low, which affects the experience of the user, but the application first generates initial image data according to the instruction by receiving a screen printing instruction, then compresses the image data, decompresses the compressed image data, and sends the decompressed image data to the control card connected with the target display screen body, thereby avoiding the defect that the image data needs to be generated on the receiving card in the existing hardware screen printing, and the types of the receiving card are not limited, so that hardware screen printing can be realized on all types of receiving cards, and the operating efficiency of the hardware screen printing is improved, the image processing efficiency is improved, and the experience of the user is improved.
