High-brightness hybrid compressive light field display with improved image quality

Abstract

Previous LCD-based multiplicative compressive light field (CLF) display has the trade-off between the brightness and the depth of field (DOF). In this paper, we propose a hybrid CLF display using a reflective polarizer and RGB mini-LED panel. By the polarization-multiplexing and the reflector dam (RD) designed on the mini-LED panel, the proposed system can preserve high brightness while enhancing the DOF. Then, a decomposition algorithm is proposed to improve the image quality by depth segmentation and limiting the motion parallax. Compared to the conventional hybrid CLF display, the brightness of the proposed system reaches 348 nits and the reconstruction quality achieves structural similarity index measure (SSIM) improvement by 0.12. The experiments also demonstrate that the proposed method could achieve a higher brightness, larger depth of field, and higher image quality.
