Abstract
A device display includes a light guide with an optical fiber embedded in an optically transparent material, a pixel array that has a pixel aligned with a first end of the optical fiber, and a reflective mechanism provided at a second end of the optical fiber. The reflective mechanism is capable of reflecting light, received by the pixel, back to the pixel via the optical fiber.
Claims20
A device display, comprising:
- a light guide that includes:
- an optically transparent material, and
- an optical fiber embedded in the optically transparent material, where the optical fiber includes a first end and a second end, and the optical fiber is to guide light along its length by total internal reflection;
- a pixel array that includes a pixel aligned with the first end of the optical fiber;
- and
- a reflective mechanism provided at and in contact with the second end of the optical fiber, where the reflective mechanism is to reflect light, received by the pixel, back to the pixel via the optical fiber,
- wherein the reflective mechanism comprises a retro-reflective shape formed at the second end of the optical fiber.
4 more elements
A device display, comprising:
- a pixel array that includes a pixel associated with one or more retro-reflective shapes provided on a side of the pixel array facing the light guide, the one or more retro-reflective shapes being capable of reflecting light, received by the pixel, back to the pixel.
A method, comprising:
- providing a light guide for a device display that includes a pixel array with a pixel, the light guide including an optical fiber embedded in an optically transparent material;
- aligning a first end of the optical fiber with the pixel of the pixel array;
- and
- providing a reflective mechanism at a second end of the optical fiber, the reflective mechanism being capable of reflecting light, received by the pixel, back to the pixel via the optical fiber.
