在非常规基板上制造电子电路大大拓宽了它们的应用领域。例如，通过利用可生物降解或可回收的基材实现的绿色电子产品可以减轻在其使用寿命结束时出现的固体废物问题。在这里，我们结合丝网印刷，高精度激光钻孔和热蒸发，在标准打印纸上制造有机场效应晶体管（OFET）有源矩阵（AM）阵列。器件的迁移率和通断比分别高达0.56 cm2V−1s−1和109。小电极重叠产生39 kHz的截止频率，这支持我们的调幅阵列适用于新的实际应用。我们演示了具有可编程扫描和信息显示功能的8 × 8 AM发光二极管（LED）驱动器。调幅阵列结构具有良好的放大潜力。
The fabrication of electronic circuits on unconventional substrates largely broadens their application areas. For example, green electronics achieved through utilization of biodegradable or recyclable substrates, can mitigate the solid waste problems that arise at the end of their lifespan. Here, we combine screen-printing, high precision laser drilling and thermal evaporation, to fabricate organic field effect transistor (OFET) active-matrix (AM) arrays onto standard printer paper. The devices show a mobility and on/off ratio as high as 0.56 cm2V−1s−1 and 109 respectively. Small electrode overlap gives rise to a cut-off frequency of 39 kHz, which supports that our AM array is suitable for novel practical applications. We demonstrate an 8 × 8 AM light emitting diode (LED) driver with programmable scanning and information display functions. The AM array structure has excellent potential for scaling up.
