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： Electronic devices may be provided with displays having polarizer structures. Polarizer structures may incorporate flexible layers of glass. The flexible glass layers may be laminated to other sheets of material in the polarizer structures using roll-to-roll lamination equipment. After the polarizer structures are cut into panels, the panels may be laminated to liquid crystal display structures, organic light-emitting-diode display structures or other display structures using sheet-to-sheet lamination tools. Ultraviolet-light-blocking material may be incorporated into a display to prevent damage to the polarizer layers in the polarizer structures. Coatings such as antireflection coatings, antistatic coating, and anti-smudge coatings may be provided on the polarizer structures. Displays may use the flexible glass layers and additional protective layers to prevent a polarizer layer from being exposed to excessive moisture. A birefringent layer may be incorporated into a display and may serve as a protective layer for a polarizer.

摘要： Systems and methods are directed to reducing surface reflections on an electronic display device having a touch-screen panel. A touch-screen panel may contribute to undesirable reflection of external light. For example, a touch-screen panel typically includes conductive electrodes which may significantly reflect ambient light, resulting in decreased visibility of displayed images. In some embodiments, a circular polarizer is disposed over a touch-screen panel in the display device. The circular polarizer includes a linear polarizer and a quarter-wave plate to modify the polarization of the external light traveling towards and reflecting from the touch-screen panel and absorbing the reflected light from the touch-screen panel to significantly reduce undesirable light reflections from the touch-screen panel.

摘要： Techniques are provided for controlling the colors of reflected light out of a display surface in a display device, such that display discoloration (e.g., green tinting) may be reduced, particularly when the display is operating in bright ambient environments. In one embodiment, a display device may include a color filter black mask layer having an arrangement of red, green, and blue color filter areas, where the red and/or blue color filter areas are substantially greater than the green color filter area. In some embodiments, the display device may include red and blue color filter pigment resin areas which may be disposed over the reflective areas to increase the overall amount of red and blue light that will be generated by reflected light to result in a total light reflection that is substantially neutral in color.

摘要： One embodiment of the present invention provides a display that emits circularly-polarized light. This display includes a display mechanism that emits linearly-polarized light and a layer placed in the path of the linearly-polarized light. The layer receives the linearly-polarized light on one surface, converts the linearly-polarized light to circularly-polarized light, and then emits the circularly-polarized light from another surface. By emitting circularly-polarized light, the display reduces the perceived distortion found at some angles when the display is viewed through a linearly-polarizing filter.
