Abstract: An electronic device such as a head-mounted device may have displays that are viewable by the eyes of a viewer through adjustable lenses. The adjustable lenses may be liquid crystal lenses. A camera and other sensors in the head-mounted device may monitor the eyes of the user and gather other information. Control circuitry in the head-mounted device may control the adjustable lenses based on measured characteristics of the eyes of the user such as interpupillary distance and direction-of-view. The control circuitry may match the distance between the centers of the adjustable lenses to the measured interpupillary distance and may align the lens centers with the measured direction-of-view. The adjustable lenses may have transparent electrodes that are supplied with time-varying control signals by the control circuitry.

Abstract: An electronic device includes a display having a reference array that includes a first pixel. The display also includes a first emission power supply coupled to the first pixel. The display further includes an active array having a second pixel. The display also includes a second emission power supply coupled to the second pixel.

Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The display may be operated in at least a normal viewing mode, a privacy mode, an outdoor viewing mode, and a power saving mode. The different view modes may exhibit different viewing angles. In one configuration, the display may include a switchable phase retarder that can be selectively activated to help reduce contrast ratios at higher viewing angles. A rotated pixel design that includes one or more groups of parallel fingers can be used to help properly align the low contrast regions. In another configuration, the display may include multiple electrically controlled birefringence (ECB) layers that can be selectively activated to provide a desired cone of vision, a region outside of which exhibits substantially reduced contrast ratios.

Abstract translation: 电子设备可以产生要显示在显示器上的内容。 显示器可以具有用于显示内容的图像帧的液晶显示像素阵列。 显示器可以至少在正常观看模式，隐私模式，室外观看模式和省电模式下操作。 不同的视图模式可以呈现不同的视角。 在一种配置中，显示器可以包括可切换的相位延迟器，其可以选择性地被激活以帮助在较高视角下降低对比度。 可以使用包括一组或多组平行手指的旋转像素设计来帮助正确对准低对比度区域。 在另一种配置中，显示器可以包括多个电控双折射（ECB）层，其可被选择性地激活以提供期望的视锥，其外侧的区域显示出显着降低的对比度。
