… Recently, we demonstrated a novel advanced autostereoscopic 3D display, which we have named the dual-layer parallax barrier (DLPB). It can shift the position of the viewing zones without heavily increasing the viewing distance by combining a dual PB, dual pairs of indium tin oxide (ITO), and a liquid crystal (LC). In addition to providing dynamic viewing zones, the DLPB’s independent ITO pairs sandwich a common LC, which reduces its thickness. Moreover, when connected to a head tracking system, it provides a smooth transition of 3D depth feeling as the viewer changes position (Figure 2). …
Summary…
Currently, the need to track the position of the viewer means that our DLPB system operates for only a single viewer. In our future work, we plan to implement an ‘advanced dual layer parallax barrier’ method that uses a virtual PB layer to increase the number of beam-forming states without any structural changes to the current DLPB structure. We hope to extend it to a multi-viewer environment in the near future.
