Abstract: Systems and methods for operating a display by dynamically determining a refresh rate for the display. In certain implementations, a processor determines a number of pixels having medium grayscale levels from a histogram for the image. If the number does not exceed a threshold, the processor sets a refresh rate for the display to a first refresh rate. In certain implementations, if the number exceeds a threshold, the processor may set the refresh rate for the display to a second refresh rate. Moreover, the first refresh rate may be lower than the second threshold. In some implementations, the image may be analyzed by subdividing the image into blocks and determining a refresh rate based on grayscale levels or distributions in the blocks. Based on the analysis of the blocks, a corresponding refresh rate may be selected.

The data driver includes a second DAC coupled to the first DAC and configured to provide an external gamma voltage signal configured to provide a second adjustment to the image data signal, and an output buffer configured to supply the image data signal to pixels of the display panel, wherein the image data signal comprises the first adjustment and the second adjustment.

The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.

Abstract: An electronic device may have a main display and an ancillary display. The device may also have a backlit keyboard with glyphs. An ambient light sensor may measure ambient light levels. Control circuitry in the laptop computer may adjust the color cast of content on the ancillary display depending on whether the content contains glyphs or other input display content or whether the content contains images, color gradients, or other output display content. Input display content may be matched in color cast to the color cast of the glyphs, which may be determined based on backlight status and/or measured ambient light information. Output content may be color matched to the main display.

Abstract: An array of pixels in a display may be illuminated by a backlight having an array of light-emitting diodes in an array of respective light-emitting diode cells. A cavity reflector in each cell may help distribute blue light emitted from the light-emitting diode of that cell toward edges of the cell. Optical films in the backlight may include a photoluminescent layer such as a phosphor layer that converts blue light from the light-emitting diode array into white light and may include a dichroic filter for reflecting white light away from the diode array towards the pixel array. A light diffuser layer for the backlight may have printed white ink pads, recesses filled with a high index of refraction material, protrusions for light scattering, light-scattering particles, thin-film interference filters, partially reflective mirrors, and other structures for diffusing the light from the light-emitting diodes.

Abstract: A display may include a color filter layer, a liquid crystal layer, and a thin-film transistor layer. A camera window may be formed in the display to accommodate a camera. The camera window may be formed by creating a notch in the thin-film transistor layer that extends inwardly from the edge of the thin-film transistor layer. The notch may be formed by scribing the thin-film transistor layer around the notch location and breaking away a portion of the thin-film transistor layer. A camera window may also be formed by grinding a hole in the display. The hole may penetrate partway into the thin-film transistor layer, may penetrate through the transistor layer but not into the color filter layer, or may pass through the thin-film transistor layer and partly into the color filter layer.

Abstract: An electronic device may have a display such as a liquid crystal display. The display may have an array of pixels that display images to a user. Backlight structures may provide the array of pixels with backlight illumination at a backlight illumination level. The backlight structures may have a light source with an array of light-emitting diodes and photoluminescent material that is pumped by pump light from the light-emitting diodes. The backlight illumination may experience color variations as a function of the backlight illumination level. Circuitry in the electronic device may be used to implement a backlight level color compensator. The backlight level color compensator may apply color correction factors to the image data of the displayed images to compensate for variations in color of the image data due to variations in backlight illumination level and operating temperature.

A water outlet of a bottom of the metallic sink is integrally formed with an annular ring extending outward from the bottom of the metallic sink. The annular ring is fixedly connected with a connecting sleeve. The connecting sleeve is formed with outer threads.

The retaining rim portion is connected with a locking sleeve. The locking sleeve is formed with inner threads corresponding to the outer threads of the connecting sleeve. The inner threads mesh with the outer threads, such that the retaining rim portion of the drain connector is tightly locked to the bottom end of the connecting sleeve to connect with the annular ring and the water outlet.

Abstract: A display may have an array of pixels that display images for a user. The backlight unit may have a light-guide layer. An array of light-emitting diodes may emit light into an edge of the light-guide layer. The light guide layer may overlap a backlight reflector. The backlight reflector may include a backlight reflector panel formed from a stack of dielectric layers on a rectangular substrate. The backlight reflector may also include a strip of backlight reflector tape having an edge that is overlapped by an edge portion of the backlight reflector panel. Color compensating features such as printed colored ink patterns may be formed on the backlight reflector to adjust the color of backlight illumination in portions of the backlight unit adjacent to the light-emitting diodes.

Abstract: A display such as a liquid crystal display may have an array of pixels that is illuminated using backlight illumination from a backlight. The backlight may have a light guide plate that distributes light from light-emitting diodes across the display. The light-emitting diodes may be overlapped by the light guide plate and may emit light into portions of the light guide plate that have ramped profiles. Light-emitting diodes for the backlight may have multiple light-emitting diode dies mounted on common package substrates. Reflective walls may be formed between the light-emitting diode dies on a substrate. Phosphor may cover the dies. The light-emitting diodes may contain four light-emitting diode dies that emit light in four different directions. Two or more of the dies may emit light of different colors. Light may be emitted into the corners of rectangular light distribution regions of a light guide plate.

Abstract: A display may have a backlight with a row of light-emitting diodes that emit light into an edge surface of a light guide layer. The light guide layer may have opposing planar surfaces. Light-scattering structures such as light-scattering holes that extend between the planar surfaces may be used to scatter rays of light by refraction and/or diffraction and can thereby homogenize light from the light-emitting diodes. The homogenized light may then be extracted from the light guide layer and may serve as backlight illumination for an array of pixels such as an array of liquid crystal display pixels. Light-scattering structures such as grooves, pits, bumps, and other structures for scattering light from the light-emitting diodes may be formed on the edge surface of the light guide layer to enhance light mixing.
