Based on temporal-multiplexing, super multi-view (SMV) technology gets implemented on a near-eye three-dimensional (3D) display, successfully overcoming the vergence accommodation conflict (VAC). The proposed system has two eyepieces for two eyes, respectively, each of which is constructed by an organic light-emitting diode (OLED) micro-display, a projecting lens, and a gating-aperture array. The gating-aperture arrays, consisting of gating apertures with an interval smaller than the diameter of the viewer’s pupil, are attached to the projecting lenses and gate different spatial segments of the projecting lens’s exit aperture in time sequence. Through refreshing the corresponding display contents synchronously, two or more light rays passing through a displayed point are guided by the gating-aperture array into each eye sequentially. Based on the persistence of vision, these light rays converge into a spatial light spot that the eye can focus on naturally, thus enabling a consistence between focusing distance and convergence distance. Further, gating-aperture array with polarization characteristics is designed to get a larger field of view (FOV), accompanied by a half-wave variable retarder being inserted between the OLED micro-display and the gating-aperture array in each eyepiece. Employing two OLED micro-displays of 120-Hz frame rates, a near-eye 3D display prototype has been demonstrated with an FOV 40 deg and a display frequency of 40 Hz, being free from VAC.

超多视角近眼3D显示，视野扩大

基于时间复用的超多视图 (SMV) 技术在近眼三维 (3D) 显示器上实现，成功克服了聚光调节冲突 (VAC)。该系统具有两个分别用于两只眼睛的目镜，每个目镜由有机发光二极管 (OLED) 微显示器、投影透镜和选通孔径阵列构成。由间距小于观察者瞳孔直径的选通孔径组成的选通孔径阵列附接到投影透镜并按时间顺序选通投影透镜出射孔径的不同空间段。通过同步刷新相应的显示内容，通过显示点的两条或多条光线​​被选通孔径阵列依次引导到每只眼睛中。基于视觉的暂留，这些光线会聚成一个人眼可以自然聚焦的空间光斑，从而使聚焦距离和会聚距离保持一致。此外，具有偏振特性的选通孔径阵列旨在获得更大的视场（FOV），并在OLED微显示器和每个目镜中的选通孔径阵列之间插入半波可变延迟器。采用两个 120Hz 帧速率的 OLED 微型显示器，近眼 3D 显示器原型已经展示了具有 40 度 FOV 和 40 Hz 显示频率，不受 VAC 影响。具有偏振特性的选通孔径阵列旨在获得更大的视场 (FOV)，同时在 OLED 微显示器和每个目镜中的选通孔径阵列之间插入一个半波可变延迟器。采用两个 120Hz 帧速率的 OLED 微型显示器，近眼 3D 显示器原型已被证明具有 40 度的 FOV 和 40 Hz 的显示频率，不受 VAC 影响。具有偏振特性的选通孔径阵列旨在获得更大的视场 (FOV)，同时在 OLED 微显示器和每个目镜中的选通孔径阵列之间插入一个半波可变延迟器。采用两个 120Hz 帧速率的 OLED 微型显示器，近眼 3D 显示器原型已被证明具有 40 度的 FOV 和 40 Hz 的显示频率，不受 VAC 影响。
