在本文中，我们提出了一个功能集成塑料系统。我们已经制造了阵列的有机薄膜晶体管（OTFT）和印刷电子元件驱动电泳墨水显示器高达70毫米的70毫米的一个单一的柔性透明塑料箔。通过在晶体管之间或逻辑块之间喷墨印刷导电银线和聚（3，4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）电阻器的附加工艺步骤，晶体管阵列被快速且可靠地配置用于不同的逻辑功能。在阵列上演示的电路功能和特性包括7级环形振荡器、D型触发器存储元件、2：4解复用器、可编程阵列逻辑器件（PAL）以及印刷导线和电阻器。触摸输入传感器也被印刷，因此完整的电子子系统只需要外部电池。PAL具有8个输入，8个输出，32个乘积项，并在使用二极管负载逻辑的3金属工艺中具有1260个p型聚合物晶体管。据我们所知，这是第一次展示了有机晶体管的PAL概念，也是第一次将有机晶体管用作柔性显示器的控制逻辑，两者都集成在单个塑料基板上。增材喷墨印刷工艺提供的多功能性非常适合塑料基板上的有机可编程逻辑，实际上，使柔性有机电子产品更加灵活。皇冠版权所有（C）2014由Elsevier B.V.发布
In this paper, we present a functional integrated plastic system. We have fabricated arrays of organic thin-film transistors (OTFTs) and printed electronic components driving an electrophoretic ink display up to 70 mm by 70 mm on a single flexible transparent plastic foil. Transistor arrays were quickly and reliably configured for different logic functions by an additional process step of inkjet printing conductive silver wires and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) resistors between transistors or between logic blocks. Among the circuit functions and features demonstrated on the arrays are a 7-stage ring oscillator, a D-type flip-flop memory element, a 2:4 demultiplexer, a programmable array logic device (PAL), and printed wires and resistors. Touch input sensors were also printed, thus only external batteries were required for a complete electronic subsystem. The PAL featured 8 inputs, 8 outputs, 32 product terms, and had 1260 p-type polymer transistors in a 3-metal process using diode-load logic. To the best of our knowledge, this is the first time that a PAL concept with organic transistors has been demonstrated, and also the first time that organic transistors have been used as the control logic for a flexible display which have both been integrated on to a single plastic substrate. The versatility afforded by the additive inkjet printing process is well suited to organic programmable logic on plastic substrates, in effect, making flexible organic electronics more flexible.
