  • Publication number: 20220392965
    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.

  • Patent number: 11495176
    Abstract: An electronic device may include a display and a sensor under the display. The display may include pixels having emission transistors that are controlled by emission signals. The emission signals are controlled using a pulse width modulation (PWM) scheme to control the brightness of the display. The emission signals may further include a localized sensor blackout pulse configured to generate a localized sensor blackout region that overlaps with the sensor to reduce any undesired back emission of light emitted from the display. The sensor blackout pulse may be automatically generated periodically or generated in an on-demand basis once per frame, multiple times per frame time, or once every multiple frames. Any luminance degradation caused by the sensor blackout pulse may be compensated by boosting the luminance and/or by extending the duration of each emission on pulse.
