Image display method and device for head mounted display

A head mounted display, comprising:

• a first display screen and a second display screen, configured to display an image;
• one or more processors;
• a memory storing one or more computer programs, wherein the one or more computer programs comprise instructions that, when executed by the one or more processors, cause the head mounted display to perform operations comprising:
• displaying an ith frame of a first image on the first display screen in a first time period of an ith display cycle, wherein i is a positive integer;
• stopping displaying the ith frame of the first image and stopping supplying power to the first display screen;
• and
• after stopping displaying of the ith frame of the first image and stopping supplying power to the first display screen, starting to supply power to the second display screen and displaying an ith frame of a second image on the second display screen in a second time period of the ith display cycle, wherein
• after the second time period ends, no image is displayed on the first display screen and the second display screen in a third time period of the ith display cycle,
• the first time period of the ith display cycle is a period during which the ith frame of the first image is displayed on the first display screen and power is supplied to the first display screen and not supplied to the second display screen, the second time period of the ith display cycle is a period during which the ith frame of the second image is displayed on the second display screen and power is supplied to the second display screen and not supplied to the first display screen, the third time period of the ith display cycle is a period during which no image is displayed on the first display screen and the second display screen,
• in the ith display cycle, the second time period is immediately following the first time period, and the sum of the first time period, the second time period, and the third time period is less than or equal to the ith display cycle.

A non-transitory computer-readable storage medium storing one or more programs including instructions, which, when executed by one or more processors of an electronic device, cause the electronic device to:

• display an ith frame of a first image on a first display screen in a first time period of an ith display cycle, wherein i is a positive integer;
• stop displaying the ith frame of the first image and stop supplying power to the first display screen;
• and
• after stopping displaying of the ith frame of the first image and stopping supplying power to the first display screen, start to supply power to a second display screen and display an ith frame of a second image on the second display screen in a second time period of the ith display cycle, wherein
• after the second time period ends, no image is displayed on the first display screen and the second display screen in a third time period of the ith display cycle,
• the first time period of the ith display cycle is a period during which the ith frame of the first image is displayed on the first display screen and power is supplied to the first display screen and not supplied to the second display screen, the second time period of the ith display cycle is a period during which the ith frame of the second image is displayed on the second display screen and power is supplied to the second display screen and not supplied to the first display screen, the third time period of the ith display cycle is a period during which no image is displayed on the first display screen and the second display screen,
• in the ith display cycle, the second time period is immediately following the first time period, and the sum of the first time period, the second time period, and the third time period is less than or equal to the ith display cycle.
