Abstract: An electronic device may have a liquid crystal display having a backlight and color mixing prevention structures. The color mixing prevention structures may, in part, be formed from one or more arrays of color filter elements. The liquid crystal display may include first and second transparent substrate layers on opposing sides of a liquid crystal layer. The display may include a first array of color filter elements on the first transparent substrate layer and a second array of color filter elements on the second transparent substrate layer. One or more of the arrays of color filter elements may include a black matrix formed over portions of the color filter elements. The color filter elements may fill or partially fill openings in the black matrix. The display may include a collimating layer on the second transparent substrate layer. The color filter elements may include cholesteric color filter elements.

Abstract: A display may have a layer of liquid crystal material between a color filter layer and a thin-film transistor layer. Column spacer structures may be formed between the color filter layer and the thin-film transistor layer to maintain a desired separation between the color filter and thin-film transistor layers. Column spacers may be deposited in column spacer regions of the color filter layer. The color filter layer may include rows of red, green, and blue color filter elements. Blue color filter material that forms blue color filter elements in the color filter layer may also be used to form a planar surface over red and green color filter elements in the column spacer regions. Using the blue color filter material to planarize the surface on which column spacers are formed ensures that the column spacers provide sufficient support for the display without requiring an additional planarization layer.

Abstract: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.

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 light guiding layer may be incorporated into an electronic device with multiple displays to create a seamless display surface between the adjacent displays. The light guiding layer may have a first portion that overlaps the active area of a first display panel, a second portion that overlaps the active area of a second, adjacent display panel, and a third portion that overlaps the inactive areas of the first and second display panels. The light guiding layer may redirect light from the active area of each display panel to the region above the inactive areas of the display panels where it is emitted towards the viewer. The light guiding layer therefore effectively hides the border between the two display panels by emitting light in that region. The light guiding layer may include light leakage promotion structures to ensure light is emitted in the border region.

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: A display may have an array of pixels. The pixels may have color filter elements such as red, green, and blue color filter elements. A layer of opaque material may be used to form a black matrix. The black matrix may have openings that receive the color filter elements. A backlight unit may produce backlight illumination for the display. A reflector layer may be interposed between the black matrix and the backlight unit. The reflector layer may have openings aligned with the openings in the black matrix and the color filter elements and may overlap the black matrix. Some of the backlight from the backlight unit may pass through the color filter elements. Other backlight may by be recycled by being reflected off of the reflector layer, thereby enhancing backlight efficiency.

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.
