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 compensating and programming operations. The array of display pixels may have rows and columns. Row lines may be used to apply row control signals to rows of the display pixels. Column lines (data lines) may be used to apply display data and other signals to respective columns of display pixels. A bottom conductive shielding structure may be formed below each drive transistor. The bottom conductive shielding structure may serve to shield the drive transistor from any electric field generated from the adjacent row and column lines. The bottom conductive shielding structure may be electrically floating or coupled to a power supply line.

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: Ein Display kann ein Array von organischen Leuchtdioden-Display-Pixeln aufweisen, die mit einer niedrigen Bildwiederholrate arbeiten. Jedes Display-Pixel kann einen Treibertransistor aufweisen, der mit einem oder mehreren Emissionstransistoren und einer jeweiligen organischen Leuchtdiode (OLED) in Reihe gekoppelt ist. Ein Oxidhalbleiter-Transistor kann zwischen einen Drain-Anschluss und einen Gate-Anschluss des Treibertransistors gekoppelt sein, um dazu beizutragen, Leckage während Display-Operationen mit niedriger Bildwiederholrate zu reduzieren. Ein Siliziumtransistor kann ferner zwischen dem Oxidhalbleiter-Transistor und dem Gate-Anschluss des Treibertransistors zwischengeschaltet sein. Eine oder mehrere Kondensatorstrukturen können mit dem Source-Anschluss und/oder dem Drain-Anschluss des Oxidhalbleiter-Transistors gekoppelt sein, um den Ausgleichsstrom zu reduzieren, der durch den Oxidhalbleiter-Transistor fließen könnte, wenn er abgeschaltet wird. Bei einer derartigen Konfiguration wird jeder Emissionsstrom, der durch die OLED fließt, unempfindlich gegenüber einer möglichen Drift in der Schwellenspannung des Halbleiteroxid-Transistors sein.

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.
