薄膜晶体管（TFT）是一种电压控制电流场通断的微小开关，是半导体电路最关键的基础组成单元之一。薄膜晶体管当下最广泛应用于LCD/OLED/QLED/Mini-LED/Micro-LED 等平板显示面板制造。在显示面板中，TFT是像素寻址、像素驱动、像素补偿、时序控制（GOA、DEMUX……）等功能实现过程中最基础、最重要的元器件。TFT应用场景还包括：下一代印刷OLED/QLED显示、下一代电浸润微流控芯片等先进实验的核心芯片、满足不同场景如医疗的新型光电/压力/生物/化学等类型的传感器、智能物联网组件及仿生电子产品等等。
The thin-film transistor (TFT) is a semiconducting switch that controls the on-off of the current field by applying different voltages and is one of the most critical semiconductor elements. The most widespread application of thin-film transistors is currently used in LCD/OLED/QLED/Mini-LED/Micro-LED and other flat panel display panel manufacturing. In the display panel, TFT is the most basic and important component in the realization of pixel addressing, pixel driving, pixel compensation, timing control (GOA, DEMUX…), and other functions. TFT application scenarios also include core chips for advanced experiments such as next-generation printed OLED/QLED displays, next-generation electrowetting microfluidic chips, new photoelectric/pressure/biological/chemical sensors that meet different application scenarios, smart IoT components and bionic electronic products, etc.

有机薄膜晶体管（OTFT，organic thin film transistor）本质仍是一种场效应晶体管，其基本结构和功能与传统的薄膜晶体管相同，不同的是其核心材料采用了有机半导体。与现有的无机薄膜晶体管如非晶硅或多晶硅TFT相比，OTFT具有以下特点：加工温度低（一般在180℃以下）；本真柔性，适用于柔性器件制造；材料来源广泛，同时工艺过程大大简化，成本大幅度降低；适合大面积加工且环境友好。
The organic thin film transistor (OTFT) is a field-effect transistor using organic semiconductors in its channel. The basic structure and function of organic thin-film transistors (OTFTs) are basically the same as those of traditional thin-film transistors (TFTs). Compared with existing inorganic TFTs such as amorphous silicon or polysilicon TFTs, OTFTs have the following advantages: low processing temperature (generally below 180°C), true flexibility, which is highly suitable for flexible device manufacturing, a wide range of material sources and simultaneously with a greatly simplified process, greatly reduced costs; suitable for large-area processing, and at the same time environmentally friendly.
