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 data storage capacitors and other pixel circuit structures in a subset of the pixels with transparent window structures, by selectively removing portions of light-emitting diode anodes, and by shifting anodes. 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: An electronic device comprises a display and a controller. The controller is configured to determine a change in a refresh rate of the display from a first frequency to a second frequency. The controller is also configured to selectively generate a control signal configured to control emission of a light emitting diode of a display pixel of the display based on the first frequency.

Abstract: The present disclosure relates to devices and methods for reducing power consumption of a display. One electronic display includes a first switch coupled between a first gate of a first transistor and a second gate of a second transistor to selectively connect the first gate to the second gate. The display includes a second switch coupled between the second gate of the second transistor and a third gate of a third transistor to selectively connect the second gate to the third gate. The display also includes driving circuitry that controls the first switch to connect the first gate to the second gate to share a first charge between the first and second gates. The driving circuitry also controls the second switch to connect the second gate to the third gate to share a second charge between the second and third gates. Accordingly, power consumption of the display may be reduced.

Abstract: An electronic device may be provided with an organic light-emitting diode display. The display may include row driver circuitry that provides an emission control signal at an output terminal to display pixels. The emission control signals may enable or disable light emission by the pixels. The row driver circuitry may include a bootstrapping capacitor that stores charge for boosting a gate signal at an intermediate node for a pull-up transistor above a power supply voltage. The row driver circuitry may include a pull-down transistor coupled to the intermediate node. The source terminal of the pull-down transistor may be coupled to the output terminal or an additional pull-down transistor may be stacked with the pull-down transistor to reduce leakage current. Charge pump circuitry may be coupled to the intermediate node to ensure that the intermediate node is maintained at a voltage above the power supply voltage.
