Channel allocation method and apparatus for display subsystem, and storage medium

An electronic device, comprising a memory and at least one processor, wherein the memory is coupled to the at least one processor;

• the memory is configured to store computer program code including computer instructions that, when executed by the at least one processor, enable the electronic device to perform operations comprising:
• determining a target to-be-displayed layer based on a priority of a first to-be-displayed layer and a priority of a second to-be-displayed layer, wherein the first to-be-displayed layer belongs to a first domain, the second to-be-displayed layer belongs to a second domain, the first domain is different from the second domain, and the target to-be-displayed layer is a layer with a higher priority between the first to-be-displayed layer and the second to-be-displayed layer;
• and
• allocating, in at least one synthesis channel, a target synthesis channel to the target to-be-displayed layer, wherein the target synthesis channel is configured to transmit the target to-be-displayed layer to an image synthesizer, so that the image synthesizer synthesizes the target to-be-displayed layer into a to-be-displayed image.
