Display apparatus, system, and method

A display method, comprising:

• generating, by a time sequence controller, a plurality of time sequence instructions that belong to a first switching period;
• sending, by the time sequence controller, the plurality of time sequence instructions to a multi-focus image generator;
• receiving, by the multi-focus image generator from the time sequence controller, the plurality of time sequence instructions that belong to the first switching period;
• loading, by the multi-focus image generator, different spatial phase information for a plurality of times based on the plurality of time sequence instructions that belong to the first switching period;
• generating, by the multi-focus image generator, a plurality of three-dimensional (3D) image blocks at different distances based on the plurality of time sequence instructions by loading the different spatial phase information for the plurality of times, wherein each 3D image block of the plurality of 3D image blocks corresponds to a 3D image and includes different depth information;
• and
• displaying, by the multi-focus image generator, the 3D image in the first switching period.

An automobile, comprising a display apparatus that includes:
