| 20160187560 | Light Source Device and Display Apparatus - Provided are: a light source device capable of preventing light from a light source disposed to face an end surface of a light guide plate from leaking to a side in which the light guide plate emits the light without providing a new member; and a display apparatus including the light source device. A light source unit 2 is disposed to face an end surface of a light guide plate 3, and a heat spreader supporting the light source unit 2 has a shape of covering the light source unit 2. A light from the light source unit 2 is irradiated to the end surface of the light guide plate 3, as well as the protrusive plates 71 and 72 side of the heat spreader. Since the light irradiated to the protrusive plate 71 side is shielded by the protrusive plate 71, the light does not leak to a panel chassis 5 side. | 06-30-2016 |
| 20160187565 | Light Guide Plate and Method for Manufacturing the Same - A light guide plate and a method for manufacturing the same are disclosed. The light guide plate is injection-molded from an aromatic polycarbonate resin having a weight average molecular weight of about 10,000 g/mol to about 15,000 g/mol and an alkali metal content of about 40 ppb to about 100 ppb. The light guide plate has a color coordinate y variation (Δy) of about 0.0001 to about 0.0150 after being left at about 80° C. and about 90% RH for about 1,000 hours, and emits light having an about 85% to about 100% brightness of a light source. The light guide plate can exhibit excellent discoloration resistance under high temperature and high humidity conditions and can have small reduction in brightness. | 06-30-2016 |
| 20160377789 | BUTTON MODULE - A button module includes an operating member, a circuit board having a pattern for detecting touch operations on the operating member, a button arranged on the circuit board, and a light guiding component further including a front side, a back side opposite to the front side, a housing defined between the front and back sides, a recess defined in the back side for hosting a light source, a through hole extending through the front side and connecting the housing to the external space, and an optical path from an inner surface of the recess to the front side. The operating member, the circuit board and the button are located in the housing with the operating member at least partially hosted in the through hole and the button abutting the light guiding component. Light from the light source located in the recess extends along the optical path to the front side. | 12-29-2016 |
| 20160377793 | ILLUMINATION DEVICE - An illumination device includes a light source unit; and a light guide plate configured to guide light from the light source unit and to emit the light outward. The light guide plate includes an incidence surface which constitutes one end surface of the light guide plate and on which the light from the light source unit is incident, and emission surfaces which constitute opposite main surfaces of the light guide plate and from which the light incident on the incidence surface is emitted. The emission surfaces include dots formed by micro prism processing. The dots on one of the emission surfaces and the dots on the other emission surface are position-shifted in rotational symmetry with each other. | 12-29-2016 |
| 20160377794 | ILLUMINATION DEVICE - An illumination device includes a light source unit and a light guide plate configured to guide light coming from the light source unit. The light guide plate includes an incidence surface, main emission surfaces from which the light incident on the incidence surface is emitted, and an end emission surface which is opposed to the incidence surface and from which the light is emitted. At least one of the main emission surfaces has a stepped surface which is formed such that the thickness of the light guide plate becomes thinner at a side of the end emission surface than at a side of the incidence surface. The stepped surface is configured to reflect the light in a direction opposite to a light guide direction extending from the incidence surface toward the end emission surface and inclined with respect to the light guide direction. | 12-29-2016 |
