    Abstract: 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.

    Abstract: A display device may include rows of pixels that displays image data on a display. The display device also includes a circuit that performs a progressive scan across the rows of pixels to display the image data using a plurality of pixels. The circuit may then supply test data to at least one pixel of a plurality of pixels that corresponds to a first row of the rows of pixels during the progressive scan, determine one or more sensitivity properties associated with the at least one pixel based on the performance of the at least one pixel when the test data is provided to the at least one pixel, and resume the progressive scan at the at least one pixel to display the image data for the at least one pixel and a remaining portion of the plurality of pixels in the first row and remaining rows of pixels.

    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 compensation and programming operations. Each display pixel may have five p-type transistor and two capacitors. One of the five p-type transistors may serve as the drive transistor and may be compensated using the remaining four of the p-type transistors and the two capacitors. A first of the capacitors may be coupled between the gate and source of the drive transistor. A second of the capacitors may have a terminal coupled to the source. Alternatively, each display pixel may have six p-type transistors and a single capacitor. The six p-type transistors may include a drive transistor having a gate coupled to the capacitor.

    Abstract: 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.

    Abstract: An electronic device may be provided with an organic light-emitting diode display with minimized border regions. The border regions may be minimized by providing the display with bent edge portions having neutral plane adjustment features that facilitate bending of the bent edge portions while minimizing damage to the bent edge portions. The neutral plane adjustment features may include a modified backfilm layer of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.
