摘要

我们为汽车副驾驶显示器(CDD)提出了一种视角控制器(VAC)。该视角控制器与副驾驶显示器集成在一起,可为副驾驶提供必要的信息,同时最大限度地减少驾驶员的注意力分散。它由两个平行排列的液晶单元和两个负 C 膜组成。它能在不施加电压的情况下保持宽视角,并能在适当的电压下实现 35°(模拟)和 30°(实验)的防窥视角,有效阻挡来自 CDD 的驾驶员直视光强和来自侧窗的反射视光强,从而降低驾驶员的注意力。这种汽车空调在正常方向上能保持良好的透光率,在隐私模式和共享模式下都能保持对称的亮度,因此适用于各种车载显示器。这些结果表明,这种 VAC 可广泛应用于汽车显示屏,以提高驾驶安全性并改善副驾驶员的娱乐性。

Viewing angle controller using two parallel alignment liquid crystal cells for automotive systems.

We proposed a viewing angle controller (VAC) for car co-driver displays (CDDs). This VAC, integrated with the co-driver display, provides necessary information to the co-driver while minimizing driver distraction. It comprises two parallel alignment liquid crystal cells and two negative C films. It maintains a wide viewing angle without an applied voltage, and it can achieve an anti-peeping angle of 35° (simulation) and 30° (experiment) under an appropriate voltage, effectively blocking the driver's direct-view light intensity from CDD and reflect-view light intensity from the side window, which can reduce the driver's attention. This VAC maintains excellent light transmittance at a normal direction and symmetrical brightness in both privacy and share modes, making it suitable for various in-vehicle displays. Those results indicate that this VAC can be broadly applied in automotive displays to enhance driving safety and improve co-driver entertainment.

期刊介绍: The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
