monitoring whether the drawn content is third-party software;
when the drawing content is third-party software, acquiring a data packet for optimizing the display of the third-party software, and optimizing the display of the third-party software, if the acquisition fails, acquiring a first data packet of the third-party software;
and establishing an optimization strategy for the third-party software according to the data packet, outputting a second data packet containing the optimization strategy for the third-party software, and storing the second data packet locally as a data packet for display optimization of the third-party software.
7. The method for optimizing display of an electronic ink screen according to claim 6, wherein the first data packet comprises: version number, component of the third party software.
8. The method for optimizing display of an electronic ink screen according to claim 7, wherein the software optimization strategy in the second data packet comprises: and the preset drawing action relationship corresponding to the third-party software and the component.
9. A display optimization device for an electronic ink screen, comprising:
the monitoring module is used for responding to the display drawing instruction and monitoring the current drawing content;
and the drawing module is used for drawing the content to be drawn according to the foreground content, the background content and the text content respectively according to the preset drawing action according to the monitored current drawing content.
10. An electronic ink screen display terminal, comprising:
a processor;
a memory coupled to the processor, one or more applications stored in the memory and configured to be executed by the processor, the one or more applications configured to perform the method for display optimization of an electronic ink screen as recited in any of claims 1-8.
