Abstract:
Eine organische Leuchtdiodenanzeige kann abgerundete Ecken aufweisen. Ein negativer Stromversorgungspfad aus Metall kann verwendet werden, um eine negative Spannung an eine Kathodenschicht zu verteilen, während ein positiver Stromversorgungspfad verwendet werden kann, um eine positive Versorgungsspannung an jedes Pixel in der Anzeige zu liefern. Der positive Stromversorgungspfad kann eine Aussparung aufweisen, die durch den negativen Versorgungsspannungspfad belegt wird, um den Widerstand des negativen Versorgungsspannungspfades in einer abgerundeten Ecke der Anzeige zu verringern. Um Reflexionen abzumildern, die dadurch verursacht werden, dass der positive Stromversorgungspfad über eng beabstandeten Datenleitungen ausgebildet wird, kann der positive Stromversorgungspfad in einer abgerundeten Ecke der Anzeige weggelassen werden, eine Abschirmschicht kann über dem positiven Stromversorgungspfad in der abgerundeten Ecke gebildet werden oder es können nichtlineare Gate-Leitungen über dem positiven Stromversorgungspfad gebildet werden.
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:
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 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.
