    摘要: An audio output amplifying device which is adapted for use in a plurality of audio output amplifying circuits. An audio signal to be amplified is supplied to a positive phase input of a first differential amplifier. The positive phase input of a second differential amplifier is selectively coupled either to a source of a reference voltage (ground) or the source of the audio signal. A feedback circuit is connected between the output of the first differential amplifier and the negative phase inputs of both the first and second differential amplifiers. A switch is provided to selectively couple the output of the first differential amplifier to ground in one position and to allow amplification by both differential amplifiers in a second position.

    摘要: The present invention provides a backlight of a liquid crystal display device having an inclination surface on a light guide plate and preventing a breakage of a liquid crystal panel, wherein light which leaks from the inclination surface is made to return to the light guide plate and the adhesiveness of the light guide plate and a flexible printed circuit board is increased. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs are formed on a light guide plate formed on the backlight as light emitting elements. Between the plurality of light emitting elements, a projecting portion of the light guide plate is formed, and a reflection member is formed on an adhesive sheet which adheres a projection member and a flexible printed circuit board to each other. By arranging the reflective member and the cushion member close to an inclination surface, light from the inclination surface is made to return to a light guide plate side, and an external force from the outside can be alleviated by a cushion member.

    摘要: In a backlight which arranges light emitting diodes on a side surface of a light guide plate, irregularities of radiation light from the backlight can be decreased. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs which constitute a light emitting element are mounted on a light guide plate formed on the backlight, and teardrop-shaped lenses are formed on a light radiation surface of the light guide plate. By changing the advancing directions of lights radiated from the light emitting element using the teardrop-shaped lenses, it is possible to decrease irregularities of a planar light source by scattering the radiation lights from the light guide plate.
