Abstract: An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may adaptively adjust the display output based on ambient lighting conditions. For example, in cooler ambient lighting conditions such as those dominated by daylight, the display may display neutral colors using a relatively cool white. When the display is operated in warmer ambient lighting conditions such as those dominated by indoor light sources, the display may display neutral colors using a relatively warm white. Adapting to the ambient lighting conditions may ensure that the user does not perceive color shifts on the display as the user's vision chromatically adapts to different ambient lighting conditions. Adaptively adjusting images in this way can also have beneficial effects on the human circadian rhythm by displaying warmer colors in the evening.

Abstract translation: 电子设备可以包括具有显示像素阵列并具有控制显示器的操作的显示控制电路的显示器。 显示控制电路可以基于环境照明条件自适应地调整显示输出。 例如，在较冷的环境照明条件下，例如由日光控制的环境照明条件下，显示器可以使用相当冷的白色显示中性色。 当显示器在诸如由室内光源所主导的环境照明条件较暖的环境照明条件下操作时，显示器可以使用相对温暖的白色显示中性色。 适应环境照明条件可以确保用户在视觉色彩适应不同的环境照明条件时不会察觉显示器上的色彩偏移。 以这种方式自适应调整图像也可以通过在晚上显示温暖的颜色对人类昼夜节律有益。

Abstract: An electronic device may have a variable refresh rate display. Static content may be displayed on the display at a lower refresh rate than moving content to conserve power. The display may include an array of pixels. Display driver circuitry in the display may load image data into rows of the pixels. The display driver circuitry may have digital-to-analog converter circuitry that supplies data signals to the array. The display driver circuitry may respond to a variable refresh rate control signal that is asserted and deasserted depending on whether static or moving image content is to be displayed. The display driver circuitry may use the digital-to-analog converter circuitry to apply a time-varying scaling factor to the image data. The magnitude of the scaling factor may be adjusted during transitions between refresh rates to help suppress luminance variations that might otherwise result in flickering on the display.

Abstract: A display may be provided with an active central region and a peripheral inactive region. The display may have one or more flexible edges in the peripheral inactive region. Conductive lines may pass between components in the active central region such as display pixels and touch sensor electrodes and components in the inactive peripheral region such as gate driver circuitry and patterned interconnect lines. Each conductive line may have an unbent segment on a portion of a display layer in the active central region and may have a segment on the bent edge of the display layer. The display layer may be formed from a polymer or other flexible material. The bent segments may be configured to be less susceptible to increases in resistance from bending than the unbent segments.

The second component may be reflected from the reflective polarizer.

Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The dynamic range of the display may be enhanced by using the second stage to perform local dimming operations. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The color stage and monochromatic stages may share a polarizer. A color filter in the color stage may have an array of red, green, and blue elements or an array of white, red, green, and blue elements. The color stage may be a fringe field display and the monochrome stage may be an in-plane switching display or a twisted nematic stage.

Abstract: An electronic device may be provided with a display such as a liquid crystal display. The liquid crystal display may have a color filter layer, a thin-film-transistor layer, and a layer of liquid crystal material between the color filter layer and the thin-film-transistor layer. A lower polarizer may be formed under the thin-film-transistor layer. An upper polarizer may be formed on the color filter layer. A shielding antireflection layer may be formed on the upper polarizer. The shielding antireflection layer may serve both as a shielding layer that protects against display damage due to electrostatic charge and as an antireflection coating that helps to minimize reflections from the surface of the display. The shielding antireflection layer may include low and high index of refraction layers and a conductive layer such as a transparent conductive oxide layer that provides shielding.

In one embodiment, a method includes exposing a display module to light at a first intensity and measuring an amount of light transmitted through the display module. The method may also include exposing the display module to light at a second intensity and measuring an amount of that light transmitted through the display module.
