    Abstract: A display device may include rows of pixels that may display image data on a display and a circuit. The circuit may perform a progressive scan across the rows of pixels to display the image data using a plurality of pixels, supply test data to a pixel of plurality of pixels that corresponds to a first row of the rows of pixels during one frame of the progressive scan, and initiate a sensing period for determining one or more sensitivity properties associated with the pixel based on the performance of the pixel with respect to the test data in response to receiving a pulse of a first global signal. The circuit may then end the sensing period in response to receiving a second global signal and resume the progressive scan across the rows of pixels to display the image data after the sensing period ends.

    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: A display may include an array of organic light-emitting diode display pixels having transistors characterized by threshold voltages subject to transistor variations. Compensation circuitry may be used to measure a transistor threshold voltage for a pixel. The threshold voltage may be sampled by controlling the pixel to sample the threshold voltage onto a capacitor at the pixel. The pixel may include at least one semiconducting-oxide transistor, silicon transistors, and a light-emitting diode. The diode may be coupled to a data line that can be used for both data loading and compensation sensing operations. Reset operations may be performed after data programming and before emission to reset the anode voltage for the diode.

    Abstract: An electronic device display may have an array of pixel circuits. Each pixel circuit may include an organic light-emitting diode and a drive transistor. Each drive transistor may be adjusted to control how much current flows through the organic light-emitting diode. Each pixel circuit may include one or more additional transistors such as switching transistors and a storage capacitor. Semiconducting oxide transistors and silicon transistors may be used in forming the transistors of the pixel circuits. The storage capacitors and the transistors may be formed using metal layers, semiconductor structures, and dielectric layers. Some of the layers may be removed along the edge of the display to facilitate bending. The dielectric layers may have a stepped profile that allows data lines in the array to be stepped down towards the surface of the substrate as the data lines extend into an inactive edge region.
