具有类纸呈现的环境光自适应显示器
摘要：
一种电子设备可以包括显示器，该显示器具有显示像素的阵列并且具有控制该显示器的操作的显示控制电路。该显示控制电路可以以不同的模式操作该显示器。在纸模式中，显示控制电路可以使用存储的光谱反射数据来调整显示颜色，使得这些颜色呈现为它们将在印刷的纸张上所呈现的。在当环境光级别低于阈值时的低光模式中，从该显示器发出的光可以被调整为模仿白炽光源的呈现。在当环境光级别超过阈值时的强光模式中，从该显示器发出的光可以被调整为最大化在强光中的可读性。该显示器的目标白点可以基于该显示器正在以何种模式操作而被调整。
摘要（英）：

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 operate the display in different modes. In a paper mode, display control circuitry may use stored spectral reflectance data to adjust display colors such that the colors appear as they would on a printed sheet of paper. In a low light mode when the ambient light level is below a threshold, the light emitted from the display may be adjusted to mimic the appearance of an incandescent light source. In a bright light mode when the ambient light level exceeds a threshold, the light emitted from the display may be adjusted to maximize readability in bright light. The target white point of the display may be adjusted based on which mode the display is operating in.
