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.
