摘要： Electronic device backlight structures may be used to provide backlight for a display. The backlight structures may include a light source such as an array of light-emitting diodes. Light from the light source may be coupled into an edge of a light guide plate. The light guide plate may distribute the light laterally across the display. The light guide plate and other display structures may be mounted in an electronic device housing such as a metal housing having metal housing walls. A gap may separate an edge of the light guide plate from the metal housing walls. Mismatch between the coefficients of thermal expansion of the housing and the light guide plate may be minimized to minimize the size of the gap. The light guide plate may be formed from a layer of glass with printed light-scattering structures or from polymer with a filler and molded or printed light-scattering structures.

摘要： Electronic devices may be provided with display structures such as glass and polymer layers in a liquid crystal display. The glass layers may serve as substrates for components such as a color filter layer and thin-film transistor layer. The polymer layers may include films such as a polarizer film and other optical films. During fabrication of a display, the polymer layers and glass layers may be laminated to one another. Portions of the polymer layers may extend past the edges of the glass layers. Laser cutting techniques may be used to trim away excess portions of the polymer layer that do not overlap underlying portions of the glass layers. Laser cutting may involve application of an adjustable infrared laser beam.

摘要： Systems, methods, and devices are provided for maintaining a target white point on a light emitting diode based backlight. In one embodiment, the backlight may include two or more strings of light emitting diodes, each driven at a respective driving strength. Each string may include light emitting diodes from a different color bin, and the respective driving strengths may be adjusted, for example, through pulse width modulation or amplitude modulation, to maintain the target white point. In certain embodiments, the driving strengths may be adjusted to compensate for shifts in the white point that may occur due to temperature or aging. A controller may adjust the driving strengths based on feedback from a temperature sensor, from an optical sensor, from a user input, or from calibration data included within the backlight or system.

摘要： A method and system for temporal dithering of pixels in a display. The dithering of the pixels may allow for simulation of 8-bit color from a 6-bit display. Moreover, the dithering of the pixels may be selected to follow a specific pattern to minimize display artifacts, which might otherwise result from interference generated by pixel inversion techniques performed during the pixel dithering. Through application of selective dithering techniques, including utilization of specific dithering patterns, the generation of display artifacts via interference from pixel inversion techniques during the display of an image may be minimized.

摘要： Layers of material such as glass layers for displays may be cut using scribing and breaking techniques. Scribing-and-breaking equipment may include a scribe tip that forms a loop-shaped scribe line in the surface of a layer of material. The loop-shaped scribe line may have a rectangular shape with four straight sides and four rounded corners. A breaking structure such as a rectangular ring-shaped metal break frame with rounded corners may be configured to match the shape of the scribe line. During breaking operations, the layer of material may be supported on a support structure. The support structure may have a flexible material such as an elastomer and a lower-friction coating layer such as a polytetrafluoroethylene coating. The break frame may be aligned with the scribe line and may be used to press down on the layer of material, thereby breaking the layer of material along the scribe line.
