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.

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： An edge-lit backlight unit for a display is provided. In one embodiment, the backlight unit may include a light guide configured to receive light from a source and emit such light in a broad distribution to a turning film disposed over the light guide. The turning film may be configured to redirect light received from the light guide toward a normal of the turning film. In one embodiment, the light guide may be configured such that peak light distribution therefrom occurs at an incident angle of approximately sixty degrees, with broad light distribution substantially occurring over an angular range between incident angles of thirty-five and eighty-five degrees. Additionally, in one embodiment, the turning film may include multiple prisms that receive and redirect the light emitted from the light guide, and that include apex angles of less than or about sixty degrees. Additional edge-lit backlight units and methods are also disclosed.
