Image display method, image display apparatus, and electronic device

An image display apparatus, wherein the apparatus comprises:

• an obtaining unit, configured to obtain a first window and a second window on a first interface, wherein the first window is a focus window, and the second window is a non-focus window on the first interface;
• and
• a processing unit, configured to:
• draw the first window in a first frame buffer, and draw the second window in a second frame buffer, wherein the first window and the second window are drawn by a process of an operating system;
• composite the first frame buffer through a first hardware interface layer to obtain a first composite frame, and composite the second frame buffer through a second hardware interface layer to obtain a second composite frame;
• and
• control, based on the first composite frame and the second composite frame, a display apparatus to display a second interface.

An image display apparatus, comprising a processor and a memory, wherein the processor is coupled to the memory, the memory comprises instructions, and the processor is configured to read and execute the instructions in the memory, to perform:

• obtaining a first window and a second window on a first interface, wherein the first window is a focus window, and the second window is a non-focus window on the first interface;
• drawing the first window in a first frame buffer, and drawing the second window in a second frame buffer, wherein the first window and the second window are drawn by a process of an operating system;
• compositing the first frame buffer through a first hardware interface layer to obtain a first composite frame, and compositing the second frame buffer through a second hardware interface layer to obtain a second composite frame;
• and
• controlling, based on the first composite frame and the second composite frame, a display apparatus to display a second interface.
