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: A display may include an array of pixels such as light-emitting diode pixels. The pixels may include multiple circuitry decks that each include one or more circuit components such as transistors, capacitors, and/or resistors. The circuitry decks may be vertically stacked. Each circuitry deck may include a planarization layer formed from a siloxane material that conforms to underlying components and provides a planar upper surface. In this way, circuitry components may be vertically stacked to mitigate the size of each pixel footprint. The circuitry components may include capacitors that include both a high-k dielectric layer and a low-k dielectric layer. The display pixel may include a via with a width of less than 1 micron.

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.
