1. A display method implemented by a head-mounted display device, wherein the display method comprises:
making a first determination that the head-mounted display device enables a low power consumption display mode;
determining, in response to the first determination, a current display mode, wherein the current display mode is a two-dimensional display mode or a three-dimensional display mode;
determining a switching time interval based on the current display mode, wherein the switching time interval is a first switching time interval when the current display mode is the two-dimensional display mode, wherein the switching time interval is a second switching time interval when the current display mode is the three-dimensional display mode, and wherein the second switching time interval is less than the first switching time interval;
controlling a left-eye display system of the head-mounted display device to display a first image and a right-eye display system of the head-mounted display device to be turned off;
making a second determination that a first display duration of the left-eye display system has reached a first preset duration;
in response to the second determination:
turning off the left-eye display system; and
maintaining a first off state of the right-eye display system;
making a third determination that a second off state of the left-eye display system has lasted for the switching time interval;
in response to the third determination:
controlling the right-eye display system to display a second image; and
maintaining the second off state;
making a fourth determination that a second display duration of the right-eye display system has reached a second preset duration;
in response to the fourth determination:
turning off the right-eye display system; and
maintaining the second off state;
making a fifth determination that the first off state has lasted for the switching time interval; and
in response to the fifth determination:
controlling the left-eye display system to display the first image; and
maintaining the first off state.
