    • PROBLEM TO BE SOLVED: To prevent lowering of light use efficiency and be capable of switching between two-dimensional display and three-dimensional display without deteriorating display quality.SOLUTION: A three-dimensional display includes a light source device for emitting image-displaying light to a display part 1. The light source device includes: a light guide panel 3 having a fist internal reflecting surface 3A and a second internal reflecting surface 3B; a first light source 2 for sending first illuminating light to the inside of the light guide panel 3 from the side; and a second light source 4 for sending second illuminating light to the second internal reflecting surface 3B from the outside through a parallax barrier 5. The second internal reflecting surface 3B includes: a transparent area 32 for emitting the second illuminating light to the first internal reflecting surface 3A as a light ray departing from a total reflection condition; and a scattering area 31 for emitting the first illuminating light to the first internal reflecting surface 3A as the light ray departing from the total reflection condition.
    • 要解决的问题:为了防止光的使用效率的降低,并且能够在不劣化显示质量的情况下在二维显示和三维显示之间进行切换。 解决方案:三维显示器包括用于向显示部分1发射图像显示光的光源装置。该光源装置包括:导光板3,其具有第一内部反射表面3A和第二内部反射 表面3B; 第一光源2,用于从侧面向导光板3的内部发送第一照明光; 以及第二光源4,用于通过视差屏障5从外部向第二内部反射表面3B发送第二照明光。第二内部反射表面3B包括:用于将第二照明光发射到第一内部反射的透明区域32 表面3A作为离开全反射条件的光线; 以及作为离开全反射条件的光线将第一照明光发射到第一内部反射面3A的散射区域31。 版权所有(C)2012,JPO&INPIT
