Abstract

The invention provides head-mounted type display equipment which comprises a display screen, an eyeball tracking unit and a controller. The eyeball tracking unit tracks the eyeball sight position and provides information of the eyeball sight position. The controller receives the information of the eyeball sight position, judges whether time for eyeball sight to rest on the position outside the display area of the display screen exceeds the preset time, and controls the display area of the display screen to enter a non-display mode if the time for the eyeball sight to rest on the position outside the display area of the display screen exceeds the preset time.

Description

technical field [0001] The invention belongs to the field of automatic power management, and relates to a head-mounted display device. Background technique [0002] Head Mounted Display (HMD) refers to a display device that can be worn on the head. HMDs generally use a "near-eye optical system" to display multimedia information such as graphics and pictures on a display screen (such as a lens) located a few centimeters from the eyeball. According to the number of display screens, HMD can be subdivided into "single lens HMD" and "dual lens HMD". Some HMDs only display a "computer-generated image" (CGI), while some kinds of HMDs can display superimposed CGI in a "real world view". The latter is also commonly referred to as "augmented reality" because the user's image information of the real world is "enhanced" by the image attached to the display device. Specifically, the user can watch the outside world around him through the transparent lens, and can also display some mul...
