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.
