Abstract: A display may have an array of pixels each of which has a light-emitting diode such as an organic light-emitting diode. A drive transistor and an emission transistor may be coupled in series with the light-emitting diode of each pixel between a positive power supply and a ground power supply. The pixels may include first and second switching transistors. A data storage capacitor may be coupled between a gate and source of the drive transistor in each pixel. Signal lines may be provided in columns of pixels to route signals such as data signals, sensed drive currents from the drive transistors, and predetermined voltages between display driver circuitry and the pixels. The switching transistors, emission transistors, and drive transistors may include semiconducting-oxide transistors and silicon transistors and may be n-channel transistors or p-channel transistors.

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: To reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels. This allows for the thin-film transistor sub-pixels to be grouped adjacent to the central area of the active area, leaving room along an edge of the active area to accommodate one or more additional display components such as gate driver circuitry or fanout portions of data lines.

Abstract: A display may have organic light-emitting diode pixels formed from thin-film circuitry. The thin-film circuitry may be formed in thin-film transistor (TFT) layers and the organic light-emitting diodes may include anodes and cathodes and an organic emissive layer formed over the TFT layers between the anodes and cathodes. The organic emissive layer may be formed via chemical evaporation techniques. The display may include moisture blocking structures such as organic emissive layer disconnecting structures that introduce one or more gaps in the organic emissive layer during evaporation so that any potential moisture permeating path from the display panel edge to the active area of the display is completely terminated.

Abstract: An electronic device may include a display having display pixels formed in an active area of the display. The display further includes display driver circuitry for driving gate lines that are routed across the display. A hole such as a through hole, optical window, or other inactive region may be formed within the active area of the display. Multiple gate lines carrying the same signal may be merged together prior to being routed around the hole to help minimize the routing line congestion around the border of the hole. Dummy circuits may be coupled to the merged segment portion to help increase the parasitic loading on the merged segments. The hole may have a tapered shape to help maximize the size of the active area. The hole may have an asymmetric shape to accommodate multiple sub-display sensor components.

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 or display pixels in a liquid crystal display. In an organic light-emitting diode display, hybrid thin-film transistor structures may be formed that include semiconducting oxide thin-film transistors, silicon thin-film transistors, and capacitor structures. The capacitor structures may overlap the semiconducting oxide thin-film transistors. Organic light-emitting diode display pixels may have combinations of oxide and silicon transistors. In a liquid crystal display, display driver circuitry may include silicon thin-film transistor circuitry and display pixels may be based on oxide thin-film transistors. A single layer or two different layers of gate metal may be used in forming silicon transistor gates and oxide transistor gates. A silicon transistor may have a gate that overlaps a floating gate structure.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.
