项目摘要

Researchers at the University of Waterloo have created novel and unique highly energy efficient display backplane technology. They have also created a novel pixel circuit and fabrication method of reliably implementing microLEDs together with novel thin-film transistor pixel circuits onto flexible substrates. Prototypes of both rigid and flexible integrated thin-film transistor (TFT)-based pixel circuits and microLED display media have been demonstrated using methods from several UW patented and patent pending technologies. By combining the highly energy efficient backplane technology with microLED technology, a new, energy efficient display technology is enabled, one that has especially advantageous applications in the small display market. Battery life is an increasingly important issue for wearable electronics (smart watches), cellphones, and laptops where small form factors limit battery capacity. Manufacturing facilities are also seeking new approaches to increase energy efficiency to reduce manufacturing costs; the UW technology enables energy efficient displays, a ubiquitous interface at every station used by the tool operator. In addition, the displays found in these applications require superior quality images, such as those provided by the microLEDs media, that may also provide additional energy savings advantage over conventional liquid-crystal or organic light-emitting displays.

滑铁卢大学的研究人员发明了新颖独特的高能效显示背板技术。他们还创造了一种新的像素电路和制造方法，可以在柔性衬底上可靠地实现微LED和新的薄膜晶体管像素电路。基于刚性和柔性集成薄膜晶体管(TFT)的像素电路和microLED显示介质的原型已经使用几种UW专利和正在申请专利的技术的方法进行了演示。通过将高能效背板技术与MicroLED技术相结合，实现了一种新的能效显示技术，这种技术在小型显示器市场具有特别有利的应用。对于可穿戴电子产品(智能手表)、手机和笔记本电脑来说，电池寿命是一个越来越重要的问题，在这些地方，小尺寸因素限制了电池容量。制造工厂也在寻求提高能效以降低制造成本的新方法；UW技术实现了节能显示器，这是工具操作员在每个工位使用的无处不在的界面。此外，在这些应用中发现的显示器需要高质量的图像，例如由微LED介质提供的图像，这也可以提供比传统的液晶或有机发光显示器更多的节能优势。
