Abstract

A display panel is described which includes Light Emitting Diodes (LEDs) that exhibit a specified beam angle. The display panel can be used for a head-mounted display. An example of a head-mounted display includes a display panel with an array of LEDs that are controllable to form an image. The head-mounted display also includes circuitry to receive image data and render an image on the display panel. The head-mounted display also includes circuitry to detect motion of the head-mounted display. The image data is generated based in part on the motion of the head-mounted display. Each LED in the array of LEDs is configured to emit light at a specified beam angle that directs the light toward a pupil of a wearer of the head-mounted display.

Background

Virtual reality systems provide a person with the feeling of actually being immersed in a particular computer-generated virtual environment. The typical virtual reality system includes a head-mounted display, which includes circuitry to track the user’s head movements and adjust the displayed image based on the point of view indicated by the user’s head movement. The virtual reality system may also include circuitry to receive user input that enable the user to manipulate objects in the virtual environment and move within the virtual movement. Such virtual reality systems have applications in video game systems, entertainment, simulation of actual environments, and others.
