“…Full-resolution 2D display can be restored by setting one LCD to be fully-transparent; while recent lenticular designs also revert to full-resolution 2D modes [Woodgate and Harrold 2003], conventional refractive architectures must trade spatial for angular resolution. Content adaptation increases spatial resolution through temporal multiplexing of mask pairs, exploiting the trend of increasing LCD refresh rates.…”

Figure 1: 3D display with content-adaptive parallax barriers. We show that light field display using dual-stacked LCDs can be cast as a matrix approximation problem, leading to a new set of content-adaptive parallax barriers. (Left, Top) A 4D light field, represented as a 2D array of oblique projections. (Left, Bottom) A dual-stacked LCD displays the light field using content-adaptive parallax barriers, confirming both vertical and horizontal parallax. (Middle and Right) A pair of content-adaptive parallax barriers, drawn from a rank-9 decomposition of the reshaped 4D light field matrix. Compared to conventional parallax barriers, with heuristically-determined arrays of slits or pinholes, content adaptation allows increased display brightness and refresh rate while preserving the fidelity of projected images. AbstractWe optimize automultiscopic displays built by stacking a pair of modified LCD panels. To date, such dual-stacked LCDs have used heuristic parallax barriers for view-dependent imagery: the front LCD shows a fixed array of slits or pinholes, independent of the multi-view content. While prior works adapt the spacing between slits or pinholes, depending on viewer position, we show both layers can also be adapted to the multi-view content, increasing brightness and refresh rate. Unlike conventional barriers, both masks are allowed to exhibit non-binary opacities. It is shown that any 4D light field emitted by a dual-stacked LCD is the tensor product of two 2D masks. Thus, any pair of 1D masks only achieves a rank-1 approximation of a 2D light field. Temporal multiplexing of masks is shown to achieve higher-rank approximations. Non-negative matrix factorization (NMF) minimizes the weighted Euclidean distance between a target light field and that emitted by the display. Simulations and experiments characterize the resulting content-adaptive parallax barriers for low-rank light field approximation.

“…Therefore, the display is desired to be capable of switching between 2D and 3D modes. Among several kinds of 2D/3D switchable display [2][3][4][5], the switchable lenticular using liquid crystal (LC) lens exhibits merits such as low crosstalk, high transmittance, and simple fabrication. As the birefringence of the LC is relatively small and the pitch of the multi-view LC lens for large size display is very large, a much larger cell gap compare to conventional LC fabrication capability is necessary to obtain an appropriate focal length [6].…”

A multi‐electrode Fresnel‐type 2D/3D switchable display with novel structure LC lens is proposed which may achieve faster switching speed and low cross‐talk in the 3D displays by applying a discontinuous non‐uniform electric field. Furthermore, a scanning type 3D display with impulsive driving collimate backlight is proposed to solve the resolution degradation problem and decrease the dynamic crosstalk of 3D perception. A scanning prism with polymer‐stabilized blue phase liquid crystals (PS‐BPLCs) was demonstrated with an impulsive blinking backlight system of high‐resolution 3D display. The fast switching PS‐BPLC prism, whose response time was less than 1 ms, may solve the resolution degradation problem for the autostereoscopic display.

“…On the other hand, for autostereoscopic multi-view 3D display, the parallax barrier and lenticular lens approaches which mainly employ the spatially multiplexing concept, are the commonly used methods. For lenticular lens approach, the current market requirement is how to let viewers have the capability to change the focal length of the lenticular lens [5,6], adjust the lens pitch, and real-time switch the 2D/3D modes [7][8][9][10]. At present, the autostereoscopic display technologies have common limitations like the fixed range of the viewing distance, view position, and the fixed IPD value (usually 65mm).…”
