摘要： An object is to implement a narrowed picture-frame while suppressing the occurrence of light leakage and a reduction in luminance in an edge-light type backlight device. A backlight device is composed of LEDs (40); a side chassis (51) supporting a board having the LEDs (40) mounted thereon; a light guide plate (20) for allowing light emitted from the LEDs (40) to exit toward a liquid crystal panel in a planar manner; a reflection sheet (30) for allowing light traveling toward a back surface side within the light guide plate (20) to be reflected thereby; optical sheets (10) including a reflection type polarizer (11), a prism sheet (12), and a diffuser (13); and a top chassis (52) disposed on top of the optical sheets (10). Black printing (60) is provided in a part of the region of the diffuser (13). A length of the reflection type polarizer (11) is longer than a length of the light guide plate (20) such that an edge of the reflection type polarizer (11) is located closer to a side of the LEDs (40) than is an edge surface of the light guide plate (20).

摘要： Provided are a tripod constant velocity joint, and a method and a device for assembling the joint. The opening of a through-hole formed in an inner member of the tripod constant velocity joint has formed therein a tapered, reduced diameter section having a diameter tapered from the opening toward the inside. A first annular groove is formed in the side wall of a driving power transmission shaft, and a clip serving as an engaging member is engaged with the first annular groove. A second annular groove is formed in the inner wall of the through-hole in the inner member. In inserting the driving power transmission shaft through the through-hole in the inner member, the tapered, reduced diameter section guides the shaft in such a manner that the clip is contracted toward the bottom surface of the first annular groove. The clip expands and contracts due to the elasticity thereof when the positions of the first annular groove and the second annular groove coincide with each other.

摘要： In a method of controlling power of a light emitting device for image display that irradiates illumination light from divided regions, light emission brightness data of each light emitting element of the light emitting device is determined based on image data for image display (S20). Power in each region and total light emission power are computed based on the light emission brightness data of each light emitting element for each region (S40). If the computed total light emission power exceeds predetermined allowable power, the power in each region is limited so that the total light emission power is equal to or less than the predetermined allowable power (S50).

摘要： An illumination device includes an LED package, an LED driver including an FET, and a thermistor disposed on a substrate. A plurality of such LED packages are disposed on the substrate such that a first area and a second area, each determined by vertices corresponding to LED packages, are defined on the substrate. The thermistor is disposed in the first area, and the FET is disposed in the second area, which is outside of the first area. The thermistor detects a temperature in the first area. Such a configuration allows the thermistor to detect, in accordance with the temperature in the area, the temperature of heat transferred from the LED packages, without being affected by heat generated by the FET. This makes it possible to efficiently make temperature corrections to stabilize color temperature and luminance.
