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.

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： Display layers in an electronic device may be used to generate images. The display layers may include liquid crystal display layers such as upper and lower polarizers and a layer of liquid crystal material. A display cover layer may be mounted in a housing adhesive. A touch sensor layer may be mounted under the display cover layer. An air gap may separate the upper polarizer from the touch sensor layer and display cover layer. Antireflection coatings may be formed on the lower surface of the display cover layer or touch sensor layer and may be formed on the upper surface of the upper polarizer. The antireflection coatings may include coatings formed from a polymer hard coat covered with a polymer layer having a different index of refraction and may include broadband antireflection coating material formed from textured polymer or other structure exhibiting a continuously varying index of refraction.

摘要： Systems and methods are provided for controlling the light reflected from a display panel. In one embodiment, a prism mirror and a diffuse reflector are positioned between the bottom polarizer and the liquid crystal layer of a pixel to control the polarization of reflected light transmitted through the display panel. The diffuse reflector diffuses light towards the prism mirror, and the prism mirror affects the polarization of the light. When the pixel is on, the liquid crystals of the liquid crystal layer may shift the polarization of the reflected light such that it can be transmitted through the top polarizer. When the pixel is off, the liquid crystals may not substantially shift the polarization of the reflected light, and the reflected light may be polarized to be absorbed by the top polarizer. Accordingly, reflected light is substantially transmitted through the pixel when the pixel is on, and substantially absorbed by the top polarizer when the pixel is off.
摘要翻译：提供了用于控制从显示面板反射的光的系统和方法。在一个实施例中，棱镜和漫反射器位于底部偏振器和像素的液晶层之间，以控制透过显示面板的反射光的偏振。漫反射器将光漫射到棱镜反射镜，并且棱镜反射镜影响光的偏振。当像素打开时，液晶层的液晶可以使反射光的偏振偏移，使得其可以透射通过顶部偏振器。当像素关闭时，液晶可能基本上不会偏移反射光的偏振，并且反射光可以被极化以被顶部偏振器吸收。因此，当像素打开时，反射光基本上透射穿过像素，并且当像素关闭时，反射光基本上被顶部偏振器吸收。

摘要： When a user operates a touch sensor panel having an LCD device outdoors or in a bright environment, light reflecting off the device can create glare. In order to reduce glare, a user can view the device through polarized filters such as polarized sunglasses.Doing so can reduce the visibility of the image displayed on the LCD. A quarter-wave retardation film can be added to the touch sensor panel's LCD device to mitigate these effects by producing circularly polarized light. However, adding a separate quarter-wave retardation film can increase the thickness and cost of manufacturing the touch sensor panel. Embodiments of the present disclosure are directed to a touch sensor panel constructed from a base film having quarter-wave retardation properties that can produce circularly polarized light. Because the base film has the desired optical properties, a separate quarter-wave retardation film may not be needed.
摘要翻译：当用户在室外或在明亮的环境中操作具有LCD装置的触摸传感器面板时，从设备反射的光可以产生眩光。为了减少眩光，用户可以通过偏光过滤器如偏光太阳镜观看设备。否则可能会降低LCD上显示的图像的可视性。可以将四分之一波长的相位差片添加到触摸传感器面板的LCD装置中，以通过产生圆偏振光来减轻这些影响。然而，添加单独的四分之一波长延迟膜可以增加制造触摸传感器面板的厚度和成本。本公开的实施例涉及由具有可产生圆偏振光的四分之一波长延迟特性的基底膜构成的触摸传感器面板。由于基膜具有期望的光学性质，因此可以不需要单独的四分之一波长的相位差膜。
