Abstract
A head-mounted display device, where when the head-mounted display device enables a low power consumption display mode, a left-eye display system and a right-eye display system alternately display an image. A switching time interval for the left-eye display system and the right-eye display system to alternately display the image is determined based on a current display mode. Different current display modes correspond to different switching time intervals, or correspond to a same switching time interval. Therefore, in the low power consumption display mode of the head-mounted display device, one display system displays the image within a same time period to reduce power consumption of the head-mounted display device.
Claims20
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.
