This relates generally to electronic devices and, more particularly, to electronic devices with organic light-emitting diode displays.
Electronic devices often include displays. For example, an electronic device may have an organic light-emitting diode display with rows and columns of display pixels. The display pixels may each have subpixels with respective red, blue, and green color filter elements. There can be non-negligible amounts of optical absorption in the color filter material of red, blue, and green subpixels, so some designs incorporate white subpixels. Pixel rendering operations may covert red-green-blue data to red-green-blue-white data to ensure that the white subpixels are frequently used. This helps reduce power consumption, because the white subpixels are more efficient at emitting light than the colored subpixels. However, the white light emitted from a white organic light-emitting diode subpixel may have white point color coordinates that do not match target white point color coordinates, leading to images that are colored differently than desired.
It would therefore be desirable to be able to provide improved displays such as improved organic light-emitting diode displays.
