Abstract: A method and user interface for direct setting of black and white points. Black point is set using a slider (210) and matching of gray shades. White point setting is performed by having a setting object (224) move within a defined region (206), such as a square or circle, with the area (222) where the setting object moves being adjusted dynamically based on the location of the setting object (224) with respect to the defined region (206). When the area (222) is the desired white, the setting is complete. Preferably the defined region has a varying color border (220) to allow a reference for the user in moving the setting object. A more detailed setting of gray levels can be accomplished by providing a gray scale (600) with reference points (602, 608). Each reference point has an associated white point setting area (604, 610), so that settings are developed for each reference point. Settings at other locations are determined by interpolation or extrapolation.

Abstract: This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. In one embodiment, a narrowband instrument, such as a spectrometer or spectrograph, can be used for calibration of a wideband colorimeter, so that more accurate outputs can be provided. In one embodiment, an optical test equipment, which consists of both a wideband colorimeter and a narrowband spectrograph, can be used for providing a more accurately calibrated wideband colorimeter. As an example, a spectra-camera, which is a hybrid system consisting of both a wideband colorimeter and a narrowband spectrograph, can be used for simultaneous testing by both the wideband colorimeter and the narrowband spectrograph. By doing simultaneous testing, accurate calibration of the wideband colorimeter can be achieved. This specification further describes a mathematical model to characterize a wideband three channel colorimeter with a narrowband multiple channel spectrometer.

Abstract: Systems and methods for reducing or eliminating image artifacts on a dual-layer liquid crystal display (LCD) 18. By way of example, a system 10 includes a first display panel 46 and a second display panel 48. The system 10 includes a processor 12 coupled to the first display panel 46 and the second display panel 48, and configured to generate a first image, and to generate a second image to be displayed on the first display panel 46 based on the first image. The processor 12 is configured to interpolate the second image. Interpolating the second image includes adjusting the second image according to a generated objective function bounded by a first constraint. The processor 12 is configured to filter the second image, and to generate a third image to be displayed on the second display panel 48 based on the first image and the second image. The third image is generated to prevent image artifacts on the second display panel 48.

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 include a display and display control circuitry. The display may be calibrated to reduce color non-uniformity in the display. Display calibration information may be obtained during manufacturing and may be stored in the electronic device. The display calibration information may include color-specific, intensity-specific, location-specific correction factors. During operation of the display, display control circuitry may receive pixel data to be displayed by each pixel in the display. The pixel data may include color information and intensity information for each pixel. Based on the color information for each pixel, the intensity information for each pixel, and the location of each pixel in the display, the display control circuitry may determine a color-specific, intensity-specific, location-specific correction factor to apply to the pixel data for each pixel. Adapted pixel data may be supplied to each pixel in the display.

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.
