Abstract

This paper presents a solid-state volumetric 3-D display system utilizing 20 LC light shutters as a display module, which provides viewers with true depth cues. The electro-optic properties of light shutters based on normal-mode PSCT were investigated. The device shows a field-on transmittance of 86.2%. When applied an operation voltage of 100 V at 28 ^°C, the response time is 540 μs for switching-on and 180 μs for switching-off, which is suitable for the solid-state volumetric 3-D display. The stability, reliability, and repeatability of the device have also been characterized.
