Abstract: An organic light-emitting diode display may contain an array of display pixels. Each display pixel may have a respective organic light-emitting diode that is controlled by a drive transistor. At low temperatures, it may be necessary to increase the amount of current through an organic light-emitting diode to achieve a desired luminance level. In order to increase the current through the light-emitting diode, the ground voltage level may be lowered. However, this may lead to thin-film transistors within the pixel leaking, which may result in undesirable display artifacts such as bright dots being displayed in a dark image. In order to prevent leakage in the transistors, the transistors may be coupled to separate reference voltage supplies or separate control lines. Additionally, the transistors may be positioned to minimize leakage even at low ground voltage levels.

Abstract: Systems and methods are provided for differential sensing (DS), difference-differential sensing (DDS), correlated double sampling (CDS), correlated-correlated double sampling (CDS-CDS) and/or programmable capacitor matching to reduce display panel sensing noise. An electronic device may include one or more processors that generate image data according to sensing operations. The one or more processors may reference a sensing pattern as part of sensing operations. Applying test sensing signals based on the sensing pattern may help reduce error associated with sensing operations.

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: A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.

Abstract: A display may have an array of light-emitting diode pixels or pixels containing portions of a liquid crystal layer to which electric fields are applied using electrodes. A pixel with a light-emitting diode may have a drive transistor coupled in series with the light-emitting diode. A storage capacitor may be coupled to a gate of the drive transistor. A pixel with a liquid crystal portion may have a storage capacitor coupled to a given one of the electrodes in that pixel. Switching circuitry in each pixel may be used to load data from a data line into the storage capacitor of the pixel. The switching circuitry may include a semiconducting-oxide transistor coupled to an associated data line and a series-connected silicon transistor that is coupled to the storage capacitor.
