Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To increase the apparent resolution of the display in portions of the display panel with the transparent windows, the display may include a light spreading layer that includes a plurality of diffractive elements. The light spreading layer may spread visible light from the array of pixels such that the display resolution at the outer surface of the display is greater than at the display panel. The light spreading layer may selectively spread visible light but not infrared light. The display may also include a lens layer that focuses light onto the transparent windows.

Abstract: Systems and methods described herein may utilize a non-linear scaling relationship to scale brightness of selective portions of the display in a manner that reduces or eliminates perceivable banding effects. By non-linearly controlling changes in brightness of the display, a viewer may perceive a more uniform, linear dimming towards the relatively dimmer region without perceiving banding, leading to improved user experience when viewing the electronic display.

Abstract: An electronic device may have a display that displays an image. The image may be viewed through a display cover layer that overlaps the display. The display cover layer may include an optical coupling layer such as a coherent fiber bundle. A pixel expansion layer such as a diffractive layer may be incorporated between the optical coupling layer and a protective layer. The diffractive layer may create duplicate pixels to occupy otherwise non-light-emitting areas on the output surface of the display cover layer. The diffractive layer may also create duplicate pixels that overlap adjacent pixels to allow for brightness averaging. An adhesive layer or the protective layer may be used to form diffractive elements for the diffractive layer. An adhesive layer having a high index of refraction may be interposed between the optical coupling layer and the display panel to mitigate undesired reflections of ambient light.

Abstract: The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the codebook for communication. The method comprises steps of: providing a basic codebook which contains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.

Abstract: A display may have a backlight unit that provides backlight illumination. The backlight unit may include a light guide that distributes light throughout the display and an electrically adjustable lens array. The lens array may have lenses such as liquid lenses or liquid crystal lenses. By adjusting the lenses in the lens array, the angles of rays of backlight from the backlight unit may be adjusted to adjust the angle-of-view of the display. The angle-of-view of the display may also be adjusted using an electrically controllable filter layer. The electrically controllable filter layer may have a liquid crystal layer or a polymer dispersed liquid crystal layer that can be controlled using electrodes. When the electrodes apply signals to the electrically controllable filter layer, portions of the filter layer change to a dark or translucent state and restrict the angle-of-view of the display.

Abstract: An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may adaptively adjust the display output based on ambient lighting conditions. For example, in cooler ambient lighting conditions such as those dominated by daylight, the display may display neutral colors using a relatively cool white. When the display is operated in warmer ambient lighting conditions such as those dominated by indoor light sources, the display may display neutral colors using a relatively warm white. Adapting to the ambient lighting conditions may ensure that the user does not perceive color shifts on the display as the user's vision chromatically adapts to different ambient lighting conditions. Adaptively adjusting images in this way can also have beneficial effects on the human circadian rhythm by displaying warmer colors in the evening.

Abstract translation: 电子设备可以包括具有显示像素阵列并具有控制显示器的操作的显示控制电路的显示器。 显示控制电路可以基于环境照明条件自适应地调整显示输出。 例如，在较冷的环境照明条件下，例如由日光控制的环境照明条件下，显示器可以使用相当冷的白色显示中性色。 当显示器在诸如由室内光源所主导的环境照明条件较暖的环境照明条件下操作时，显示器可以使用相对温暖的白色显示中性色。 适应环境照明条件可以确保用户在视觉色彩适应不同的环境照明条件时不会察觉显示器上的色彩偏移。 以这种方式自适应调整图像也可以通过在晚上显示温暖的颜色对人类昼夜节律有益。

Abstract: Display ground plane structures may contain slits. Image pixel electrodes in the display may be arranged in rows and columns. Image pixels in the display may be controlled using gate lines that are associated with the rows and data lines that are associated with the columns. An electric field may be produced by each image pixel electrode that extends through a liquid crystal layer to an associated portion of the ground plane. The slits in the ground plane may have a slit width. Data lines may be located sufficiently below the ground plane and sufficiently out of alignment with the slits to minimize crosstalk from parasitic electric fields. A three-column inversion scheme may be used when driving data line signals into the display, so that pairs of pixels that straddle the slits are each driven with a common polarity. Gate line scanning patterns may be used that enhance display uniformity.
