LIGHT SOURCE DEVICE AND STEREOSCOPIC DISPLAY

摘要

A light source device includes: a light guide plate having first and second internal reflection planes facing each other; a first light source applying first illumination light from a side surface of the light guide plate into an interior thereof; a second light source facing the second internal reflection plane, and applying second illumination light to the second internal reflection plane; and a reflective member between the second internal reflection plane and the second light source. The second internal reflection plane is provided with a total-reflection region allowing the first illumination light to be reflected in a total-internal-reflection manner whereas allowing the second illumination light to pass therethrough, and a scattering region allowing the first illumination light to be reflected and scattered. The reflective member is disposed in a position corresponding to the scattering region, and reflects light having passed through the scattering region, toward the first internal reflection plane.

1. A stereoscopic display comprising:
a display section displaying an image; and a light source device emitting light for image display to the display section, wherein the light source device includes
a light guide plate having a first internal reflection plane and a second internal reflection plane which face each other,a first light source applying first illumination light from a side surface of the light guide plate into an interior thereof,a second light source disposed to face the second internal reflection plane of the light guide plate, and applying second illumination light,a total-reflection region provided in the second internal reflection plane, the total-reflection region allowing the first illumination light to be reflected in a manner of total-internal-reflection whereas allowing the second illumination light to pass therethrough,a scattering region provided in the second internal reflection plane, and allowing the first illumination light to be reflected and scattered, anda reflective member disposed in a position corresponding to the scattering region between the second internal reflection plane and the second light source, and reflecting light having passed through the scattering region, toward the first internal reflection plane, and the display section selectively displays one of an image based on three-dimensional image data and an image based on two-dimensional image data by switching, the first light source is controlled to be in a light-on state in the case where an image based on three-dimensional image data is displayed on the display section, and is controlled to be in a light-off state or in a light-on state in the case where an image based on two-dimensional image data is displayed on the display section, and the second light source is controlled to be in a light-off state in the case where the image based on the three-dimensional image data is displayed on the display section, and is controlled to be in a light-on state in the case where the image based on the two-dimensional image data is displayed on the display section.
