Super Multi-View Near-Eye Display Using Pinhole Arrays of Timing-Polarizing Characteristics

Among the various indicators of near-eye display devices, a compact form factor is crucial for the viewing experience of users but also a difficult goal to achieve. The pinhole-based light field display technology is regarded as an effective method to achieve this goal. Despite the numerous advantages, there are problems such as crosstalk and the vergence-accommodation conflict (VAC). This paper proposes a super multi-view near-eye light field display device to solve these two problems simultaneously. By endowing the pinhole array and the display screen with timing-polarizing characteristics, crosstalk-free near-eye four-view light field display is achieved.
