Abstract

The most common transistor technologies for making active matrix displays and sensors use hard ceramic materials for the semiconducting active layer [1]. To enable flexible displays and electronics, FlexEnable has pioneered an alternative manufacturing approach which uses soft, flexible organic materials as the active layers [2–4]. Organic thin film transistor (OTFT) backplanes using FlexiOMTM materials can be fabricated in standard flat panel display factories which are repurposed for the novel material set. A primary benefit for using OTFT is the inherent durability that comes from removing the brittle ceramic layers. This feature can be further exploited by proactively stretching the devices to conform to more attractive form factor products. This paper will discuss the electrical performance of a state-of-the-art OTFT device and impact of a thermoforming process on switching characteristics.
