20120033432 | DISPLAY ELEMENT - A display element includes a light source, an optical waveguide, a light-extracting portion. The optical waveguide has two ends and a side surface. One of the two ends is near the light source. The other of the two ends is far from the light source. The side surface extends from the one end to the other end. The light-extracting portion is provided near the side surface to extract light out of the optical waveguide. In addition, the other end changes a light path of forth-traveling light so that an incident angle of back-traveling light is smaller than the incident angle of the forth-traveling light. | 02-09-2012 |
20120207431 | OPTICAL DEVICE UTILIZING OPTICAL WAVEGUIDE AND DISPLAY DEVICE - In one embodiment, in an optical device, a bar-shaped optical waveguide has either a polygonal or circular cross-sectional shape. A light entry portion is formed in a circumferential area of a first-end surface of the optical waveguide. The light entry portion includes a sloping surface having a normal vector containing a component in a circumferential direction of the first-end surface. An incident light beam travels towards a second-end surface of the optical waveguide while repeating total reflections on a side surface of the optical waveguide. The incident light beam travels without passing through a central portion in a cross section of the optical waveguide. A light exit portion is formed in the side surface of the optical waveguide. The light exit portion is configured to let the light beam in the optical waveguide out of the optical waveguide. | 08-16-2012 |
20120327069 | DISPLAY DEVICE - According to one embodiment, a display device includes a light source, a light guide, a light extraction unit, and a drive circuit. The light source emits a first light. The light guide has a first end, a second end arranged in a first direction, and a side surface extending in the first direction. The light guide guides the first light from the first end toward the second end. The light extraction unit opposes the side surface, and includes first and second conductive units provided parallel to the side surface. The light extraction unit extracts the first light guided inside the light guide by coming close to the side surface for a state in which a voltage is applied to the first and second conductive units. The drive circuit applies the voltage between the first and second conductive units. | 12-27-2012 |
