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： An electronic device display may have display layers that provide images for a user. Backlight structures may provide backlight for the display layers. The backlight structures may include a light source such as an array of light-emitting diodes. A light guide plate in the backlight structures may be used to distribute the light from the light-emitting diodes throughout the display. The light guide plate may have a main rectangular area that overlaps the display. The main rectangular area may have refractive light scattering structures such as a layer containing clear beads. The refractive light scattering structures may scatter light from the light guide plate for use as backlight. A strip of light diffracting structures such as holographic structures or grating structures may be used to mix light from the light-emitting diodes along the border of the light guide plate.
