Abstract: Techniques are described for backlighting electronic headset display panels. The backlight can include a light guide plate that is illuminated via a light transmitting element that is coupled to a light source. The light guide plate, in turn, illuminates the display panel. The light source is located within the headset but is disposed remotely from the display panels. A photodiode is coupled to a surface of the light transmitting element and is configured to detect a characteristic of the light transmitted by the light transmitting element.

Abstract: A head-mounted display device includes a first set of one or more lenses and a first display configured to provide visual data through the first set of one or more lenses. The head-mounted display device further includes a first stepper motor mechanically coupled to the first display, and the first stepper motor is configured to move the first display along a first axis by rotating a rotatable component of the first stepper motor. The head-mounted display device further includes a first electronic controller configured to (i) determine a first position of the first display, (ii) receive information identifying a second position of the first display, and (iii) generate one or more electrical signals that cause the first stepper motor to move the first display from the first position to the second position along the first axis.

Abstract: A head-mounted display device includes one or more lenses and a display configured to provide visual data through the one or more lenses. The head-mounted display device also includes a direct-current (DC) motor mechanically coupled to the display, and the DC motor is configured to move the display along an axis by rotating a rotatable component of the DC motor. The head-mounted display device further includes: position sensor(s) configured to determine a position of the display, and electronic controller(s) in communication with the position sensor(s). The electronic controller(s) are configured to: (i) receive, from the position sensor(s), the determined position of the display as a first position of the display, (ii) receive information identifying a second position of the display, and (iii) generate electrical signal(s) that cause the DC motor to move the display from the first position to the second position along the axis.
