Abstract: A touch screen display may include gate line driver circuitry coupled to a display pixel array. The display may be provided with intra-frame pausing (IFP) capabilities, where touch or other operations may be performed during one or more intra-frame blanking intervals. In one suitable arrangement, a gate driver circuit may include multiple gate line driver segments each of which is activated by a separate gate start pulse. Each gate start pulse may only be released at the end of an IFP interval. In another suitable arrangement, dummy gate driver units may be interposed among active gate driver units. Gate output signals may propagate through the dummy gate driver units during the IFP internal. In another suitable arrangement, each active gate driver unit may be provided with a buffer portion that protects at least some transistor in the gate driver unit from undesired stress.

Abstract: Ein Display kann ein Array organischer Leuchtdiodendisplay-Pixel mit Transistoren einschließen, die durch Schwellenspannungen gekennzeichnet sind, die Transistorschwankungen unterliegen. Eine Kompensationsschaltung kann verwendet werden, um eine Transistorschwellenwertspannung für ein Pixel zu messen. Die Schwellenspannung kann abgetastet werden, indem das Pixel gesteuert wird, um die Schwellenspannung auf einen Kondensator an dem Pixel abzutasten. Das Pixel schließt mindestens einen Halbleiter-Oxidtransistor, Siliziumtransistoren und eine Leuchtdiode ein. Die Diode kann mit einer Datenleitung gekoppelt sein, die sowohl für Datenladeals auch Kompensationserfassungsvorgänge verwendet werden kann. Rückstellvorgänge können nach der Datenprogrammierung und vor der Emission ausgeführt werden, um die Anodenspannung für die Diode zurückzustellen.

Abstract: Abstract A display pixel is provided that is operable to support hybrid compensation scheme having both in-pixel threshold voltage canceling and external threshold voltage compensation. The display may include multiple p-type silicon transistors with at least one n-type semiconducting-oxide transistor and one storage capacitor. An on-bias stress phase may be performed prior to a threshold voltage sampling and data programming phase to mitigate hysteresis and improve first frame response. In low refresh rate displays, a first additional on-bias stress operation can be performed separate from the threshold voltage sampling and data programming phase during a refresh frame and a second additional on-bias stress operation can be performed during a vertical blanking frame. The display pixel may be configured to receive an initialization voltage and an anode reset voltage, either of which can be dynamically tuned to match the stress of the first and second additional on-bias stress operations to minimize flicker.

Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: Eine elektronische Einrichtung kann ein Display mit einen Array aus Display-Pixeln auf einem Substrat einschließen. Die Display-Pixel können organische Leuchtdiodenanzeigepixel oder Display-Pixel in einem Flüssigkristalldisplay sein. In einem Display mit organischen Leuchtdioden (OLED) können hybride Dünnfilmtransistor-Strukturen ausgebildet sein, die Halbleiteroxid-Dünnfilmtransistoren, Silizium-Dünnfilmtransistoren und Kondensatorstrukturen einschließen. Die Kondensatorstrukturen können die Halbleiteroxid-Dünnfilmtransistoren überlappen. OLED-Display-Pixel können Kombinationen aus Oxid- und Silicium-Transistoren aufweisen. In einem Flüssigkristalldisplay kann eine Anzeigetreiberschaltung Silicium-Dünnfilmtransistor-Schaltung einschließen, und Display-Pixel können auf Oxid-Dünnfilmtransistoren basieren. Eine einzelne Schicht oder zwei unterschiedliche Gate-Metallschichten können bei der Bildung von Siliciumtransistor-Gates und Oxidtransistor-Gates verwendet werden. Ein Siliciumtransistor kann ein Gate aufweisen, das eine Floating-Gate-Struktur überlappt.

Abstract: 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.
