    摘要: A flexible display having an array of pixels or sub-pixels is provided. The display includes a flexible substrate and an array of thin film transistors (TFTs) corresponding to the array of pixels or sub-pixels on the substrate. The display also includes a first plurality of metal lines coupled to gate electrodes of the TFTs and a second plurality of metal lines coupled to source electrodes and drain electrodes of the TFTs. At least one of the first plurality of metal lines and the second plurality of metal lines comprises a non-stretchable portion in the TFT areas and a stretchable portion outside the TFT areas.

    摘要: 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.

    摘要: An electronic device may have a flexible display with portions that are bent along a bend axis. The display may have display circuitry such as an array of display pixels in an active area. Contact pads may be formed in an inactive area of the display. Signal lines may couple the display pixels to the contact pads. The signal lines may overlap the bend axis in the inactive area of the display. During fabrication, an etch stop may be formed on the display that overlaps the bend axis. The etch stop may prevent over etching of dielectric such as a buffer layer on a polymer flexible display substrate. A layer of polymer that serves as a neutral stress plane adjustment layer may be formed over the signal lines in the inactive area of the display. Upon bending, the neutral stress plane adjustment layer helps prevent stress in the signal lines.

    摘要: An electronic device may have a flexible display with portions that can be bent. The display may include an array of display pixels in an active area. Contact pads may be formed in an inactive area of the display. Display circuitry in the active area may exhibit a given stack height, whereas display circuitry in the inactive area may exhibit a stack height that is less than the given stack height. In particular, the contact pads may be formed directly on a multi-buffer layer that sits directly on a flexible display substrate. Passivation material may be selectively formed only at the edges of the contact pad on the multi-buffer layer. The multi-buffer layer may be formed at a distance from the edge of the flexible display substrate to minimize cracking in the multi-buffer layer.

The method includes forming a thin film transistor (TFT) substrate including a first metal layer and a second metal layer. The method also includes depositing a first passivation layer over the second metal layer, and forming a third metal layer over a channel region and a storage capacitor region. The third metal layer is configured to connect to a first portion of the second metal layer that is configured to connect to the first metal layer in a first through-hole through a gate insulator and the first passivation layer. The method further includes depositing a second passivation layer over the third metal layer, and forming an anode layer over the second passivation layer. The anode is configured to connect to a second portion of the third metal layer that is configured to connect to the second metal layer in a second through-hole of the first passivation layer and the second passivation layer.

    摘要: 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.

    摘要: A touch screen having touch circuitry integrated into a display pixel stackup. The touch screen can include a transistor layer, an LED layer and a first layer. The first layer can operate as an LED cathode during a display phase and as touch circuitry during a touch sensing phase. The transistor layer can be at least partially utilized for transitioning between the display phase and the touch sensing phase. The touch screen can be fabricated to reduce or eliminate damage to the LED layer.
