Distributed real-time rendering for ultrahigh-resolution multiscreen 3D display

Large-scale autostereoscopic three-dimensional (3D) displays can give audiences a truly immersive feeling with strong visual impact. However, the traditional autostereoscopic 3D display systems are limited by the display hardware, making it difficult to directly achieve large-scale 3D displays with high resolution. Multiscreen splicing with laser backlights can be used for large-scale and ultrahigh-resolution 3D display, but it normally results in subscreen image asynchronization, view zone error, or obvious edge overlapping. To solve the problems mentioned above, a distributed real-time rendering system for ultrahigh-resolution multiscreen 3D display is proposed. Fifteen 3D LCD display devices are driven through a host, cooperating with laser backlights, a lenticular lens array (LLA), and a directional diffuser to display high resolution, high frame rate, large size, and wide-viewing angle 3D images. The resolution of the whole display system can reach 23,040 × 21,600. The rendering system provides a large-scale and real-time 3D scene image with an ultrahigh-definition resolution at a speed of 40 frames per second and high quality.
