The capability to simplify and integrate thin-film driver electronics directly onto the backplane of display and sensor array enables large-area electronics that are simpler to fabricate and provides a pathway towards mechanically flexible systems. For example, the popularity of 4K TVs and retina displays on phones and laptops require four times greater pixel density than conventional displays, increasing the demand on peripheral driver circuits. Accommodating four times as many drivers is a major challenge that 4K display manufacturers face. It is also becoming increasingly difficult to allocate space for an increasing number of connecting pads and the corresponding drivers required for each row and column in a backplane array. Similarly, for high-resolution image sensors, the need to address a high number of pixels complicates the electronic backplane design and fabrication cost for medical diagnostics. The emerging flexible electronics technology also promises mechanical flexibility at low cost but is encumbered by rigid and high-cost CMOS drivers used to address an array of pixels.The proposed project will build upon recently developed thin-film transistor logic circuitry to enhance the power, energy efficiency and reduce cost of thin-film transistor (TFTs) display backplane. The proposed implementation of de-multiplexers has the potential to reduce the number of row select pads and associated drivers by 50%, therefore significantly reducing display cost, weight while increasing energy efficiency. The carried out market research in 2016 by a third party substantiates and supports our initial assessment of the potential of the technology.

将薄膜驱动器电子直接在显示屏和传感器阵列的背板上简化和集成的能力使大面积电子设备更简单地制造，并为机械灵活的系统提供了途径。例如，在手机和笔记本电脑上的4K电视和视网膜显示器的受欢迎程度是像素密度的四倍，是传统显示器的四倍，从而增加了对外围驾驶员电路的需求。容纳4K展示制造商面临的主要挑战是许多驾驶员的四倍。为越来越多的连接垫和背板阵列中每个行所需的相应驱动程序分配空间，也越来越困难。同样，对于高分辨率图像传感器，解决大量像素的需求使电子背板设计和医疗诊断的制造成本复杂化。新兴的灵活电子技术还承诺以低成本的价格机械灵活性，但由用来解决一系列像素的僵硬和高成本的CMOS驱动程序所束缚。拟议的项目将建立在最近开发的薄膜晶体管逻辑电路上，以增强薄膜晶体管（Thin-Film Transistor（Thin-Fillm Transistor）（Thin-Fillm Transistors）的功率，tfts）。拟议的脱氧链型实施有可能将行选择垫和相关驱动器的数量减少50％，因此大大降低了显示成本，重量，同时提高能源效率。第三方在2016年进行的市场研究证明了我们对技术潜力的初步评估。
