Abstract: An electronic device may include a display having an array of display pixels on a substrate. The display pixels may be organic light-emitting diode display pixels, that include hybrid thin-film transistor structures formed using semiconducting-oxide thin-film transistors, silicon thin-film transistors, and capacitor structures. A drive transistor in the display pixel may be a top-gate semiconducting-oxide thin-film transistor and a switching transistor in the display pixel may be a top-gate silicon thin-film transistor. A storage capacitor in the display may include a conductive semiconducting-oxide electrode.

Abstract: A display may have an array of organic light-emitting diode display pixels. Each display pixel may have a light-emitting diode that emits light under control of a drive transistor. Each display pixel may also have control transistors for compensating and programming operations. The array of display pixels may have rows and columns. Row lines may be used to apply row control signals to rows of the display pixels. Column lines (data lines) may be used to apply display data and other signals to respective columns of display pixels. A bottom conductive shielding structure may be formed below each drive transistor. The bottom conductive shielding structure may serve to shield the drive transistor from any electric field generated from the adjacent row and column lines. The bottom conductive shielding structure may be electrically floating or coupled to a power supply line.

Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to associated semiconducting oxide transistors. The semiconducting oxide transistors may exhibit different device characteristics. Some of the semiconducting oxide transistors may be formed using a first oxide layer formed from a first semiconducting oxide material using first processing steps, whereas other semiconducting oxide transistors are formed using a second oxide layer formed from a second semiconducting oxide material using second processing steps different than the first processing steps. The display may include three or more different semiconducting oxide layers formed during different processing steps.

Abstract: An electronic device includes an electronic display having an active area comprising a pixel. The electronic device also includes processing circuitry configured to receive image data and predict a change in threshold voltage associated with a transistor of the pixel based at least in part on the image data. Furthermore, the processing circuitry is configured to adjust the image data to generate adjusted image data based at least in part on the predicted change in threshold voltage.

Abstract: A component such as a display may have a substrate and thin-film circuitry on the substrate. The thin-film circuitry may be used to form an array of pixels for a display or other circuit structures. Metal traces may be formed among dielectric layers in the thin-film circuitry. Metal traces may be provided with insulating protective sidewall structures. The protective sidewall structures may be formed by treating exposed edge surfaces of the metal traces. A metal trace may have multiple layers such as a core metal layer sandwiched between barrier metal layers. The core metal layer may be formed from a metal that is subject to corrosion. The protective sidewall structures may help prevent corrosion in the core metal layer. Surface treatments such as oxidation, nitridation, and other processes may be used in forming the protective sidewall structures.
