    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: 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: The present disclosure relates generally to a liquid crystal display (LCD) that has a large color gamut. In certain embodiments, the large color gamut in the LCD may be obtained by adding a spectrum-filter into different layers of the LCD. The spectrum-filter may be designed to filter a portion of a color band from a light emitted from one or more light emitting diodes (LEDs) in the LED thereby increasing the color gamut on the LCD.
