Abstract: An electronic device may have a display with an array of pixels. The device may have an array of components such as an array of light sensors for capturing fingerprints of a user through an array of corresponding transparent windows in the display. A capacitive touch sensor, proximity sensor, force sensor, or other sensor may be used by control circuitry in the device to monitor for the presence of a user's finger over the array of light sensors. In response, the control circuitry can direct the display to illuminate a subset of the pixels, thereby illuminating the user's finger and causing reflected light from the finger to illuminate the array of light sensors for a fingerprint capture operation. The display may have display driver circuitry that facilitates the momentary illumination of the subset of pixels with uniform flash data while image data is displayed in other portions of the display.

Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode. The organic light-emitting diodes may each have an anode that is coupled to a thin-film transistor pixel circuit for controlling the anode. Transparent windows may be formed in the display. The windows may be formed by replacing subpixels in some of the pixels with transparent windows. When subpixels are replaced by transparent windows, adjacent subpixels may be overdriven to compensate for lost light from the replaced subpixels. Adjacent subpixels may also be enlarged to help compensate for lost light. An array of electrical components such as an array of light sensors may be aligned with the transparent windows and may be used to measure light passing through the transparent windows.

Abstract: Systems and electronic displays with improved contrast even under bright-light conditions are provided. Such an electronic display may include a self-emissive pixel (e.g., OLED or μ-LED) with a corresponding liquid crystal switchable retarder pixel. A liquid crystal layer of the switchable retarder pixel may be tuned to an “on” state or an “off” state. In the “on” state, the switchable retarder pixel may allow outside light that enters the pixel to reflect back out of the pixel. This may add to the amount of light that appears to be emitted from that pixel. In the “off” state, the switchable retarder pixel may block the outside light that enters the pixel from reflecting back out of the pixel. This may reduce the amount of light that appears to be emitted from that pixel. Selectively controlling the switchable retarder pixels may allow for increased contrast even under bright-light conditions.
Abstract translation: 提供了即使在明亮的条件下也能提供对比度的系统和电子显示器。 这样的电子显示器可以包括具有相应的液晶可切换延迟器像素的自发射像素（例如，OLED或μ-LED）。 可切换延迟器像素的液晶层可以被调谐到“接通”状态或“断开”状态。 在“开”状态下，可切换延迟器像素可以允许进入像素的外部光反射回像素。 这可能增加似乎从该像素发射的光量。 在“关闭”状态下，可切换延迟器像素可以阻挡进入像素的外部光线从像素反射回来。 这可能减少似乎从该像素发射的光量。 选择性地控制可切换延迟器像素可以允许即使在明亮的条件下也增加对比度。
