Autostereoscopic three-dimensional display with high resolution and low cross talk using a time-multiplexed method

We propose an autostereoscopic three-dimensional (3-D) display using a time-multiplexed method. This display consists of a two-dimensional (2-D) display panel, a time-multiplexed liquid crystal parallax barrier (LCPB), and a lenticular sheet. The 2-D display provides four-view synthetic images. The time-multiplexed LCPB located in front of the 2-D display panel is used to project parallax images in different spatial directions. With the time-multiplexed method, 3-D pixels with different locations can be provided for a time sequence, allowing a high 3-D resolution to be achieved. The lenticular lens is located between the 2-D display panel and the LCPB. Because of congregating ray functions of the lenticular sheet, cross talk can be effectively reduced. We describe the principle and parameter calculations for the prototype of the proposed display. Compared with the conventional autostereoscopic 3-D display, the proposed display has a higher resolution and minimal cross talk.
