A reflected-light-source (RLS)-based 3D display is proposed. This display consists of an RLS and a 2D display panel. The 2D display panel is located in front of the RLS. The RLS consists of a light source, a light guide plate (LGP), and a reflection cavity. The light source and the LGP are located in the reflection cavity. Light from the light source can enter into the LGP and reflect continuously in the reflection cavity. The reflection cavity has a series of slits, and light can exit only from these slits. These slits can work as a postpositional parallax barrier, so when they modulate the parallax images on the 2D display, 3D images are formed. Different from the conventional 3D display based on a parallax barrier, this RLS has less optical loss, so it can provide higher brightness. A prototype of this display is developed. Experimental results show that this RLS-based 3D display can provide higher brightness than the conventional one.
提出了一种基于反射光源（RLS）的3D显示器。该显示器由一个RLS和一个2D显示面板组成。2D显示面板位于RLS的前方。RLS由一个光源、一个导光板（LGP）和一个反射腔组成。光源和LGP位于反射腔内。来自光源的光可以进入LGP并在反射腔内持续反射。反射腔有一系列狭缝，光只能从这些狭缝射出。这些狭缝可以作为后置视差屏障，因此当它们调制2D显示器上的视差图像时，就会形成3D图像。与基于视差屏障的传统3D显示器不同，这种RLS具有较低的光学损耗，因此可以提供更高的亮度。开发了该显示器的一个原型。实验结果表明，这种基于RLS的3D显示器能够提供比传统显示器更高的亮度。
