Wide Color Gamut Autostereoscopic 2D–3D Switchable Display Based on Dynamic Subpixel Arrangement

This paper is a report on the mathematical analysis and working principle of a wide color gamut autostereoscopic 2D-3D switchable display based on the dynamic subpixel arrangement method. The display prototype discussed in the paper has three major distinctions. First, the use of dynamic subpixel arrangement method and eye-tracking system has improved its performances in the resolution, crosstalk and 2D/3D switching statistics. Second, a design of Quantum-Dot-Polymer (QDP) film and optical layer combined backlight has enhanced its viewing angle and color gamut. Third, the application of parallel computing to the dynamic subpixel arrangement method has improved its real-time performance. Base on observation from finished fabrication and experiment, this prototype has already demonstrated noticeable enhancement in terms of color gamut expansion-reaching 77.98% according to ITU-R Recommendation BT.2020 (Rec.2020), and crosstalk reduction-with the minimum crosstalk rate at nearly 6%. Close comparison with two other commercial 3D displays (BENQ XL2707-B and View Sonic VX2268WM) are also presented in the paper for sufficiency.
