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 with a display having a white point and a method for operating a display having a white point. A light sensor determines a color and brightness of ambient light. Control circuitry compares the brightness of the ambient light to a threshold brightness. When the brightness of the ambient light is above the threshold brightness, the control circuitry adjusts the white point of the display based on the color of ambient light. When the brightness of ambient light is below the threshold the control circuitry fixes the white point of the display to a set white point.
