Abstract
A micro-OLED display includes a substrate with a coating made of IR-transparent material such as Zinc Selenide or Zinc Sulfide to allow a pupil tracking camera, which may include photodiodes, to be mounted directly behind the display. The coating is transparent to near infrared (NIR) radiation but opaque to visible light.
Claims20
An assembly, comprising:
- at least one organic light emitting diode (OLED) display comprising at least one innermost surface and at least one substrate;
- a coating on the substrate, the coating being transparent to at least near infrared (NIR) radiation but opaque to visible light;
- and
- at least one camera configured to generate images from IR light, the camera disposed to receive light through the coating.
1 more element
A method, comprising:
- presenting frames of demanded images on at least one head-mounted display (HMD);
- and
- at least during a null period between first and second frames, generating at least one image of a pupil of a wearer of the HMD.
A head-mounted display (HMD) for generating demanded images of at least one computer simulation based at least in part on tracking at least one pupil of a wearer of the HMD, comprising:
- at least one organic light-emitting diode (OLED) display;
- at least one pupil tracking camera configured to generate images from infrared (IR) light;
- at least one substance configured to pass IR light from the pupil to the camera for generation of the images by the camera and to block, from the camera, visible light from the OLED display such that at least one computer simulation engine configured to generate the demanded images can do so based at least in part on images from the camera.
