VueReal is a Waterloo-based company working on next-generation ultra-high resolution emissive displaysystems. More specifically, VueReal is developing a novel integration technique that enables the creation ofmicro-LED displays in a variety of structures and form factors suitable for a wide range of portable applicationssuch as cell-phones, head-up displays, pico-projectors, and smart watches as well as virtual reality (VR) andaugmented reality (AR) devices. The micro-LED display market is expected grow from the current $225M to$19.9B in 2025, a 54% compounded annual growth rate. VueReal is therefore positioned to establish aleadership role as a designer and manufacturer in this emerging market. However, VueReal is currently facing achallenge in that the efficiency of its LEDs decreases when device dimensions are reduced to few micrometers,the size scale required for micro-LED displays. The nature and causes of this efficiency droop in the small sizeLEDs is still unknown. In this project, Aziz's group at the University of Waterloo will work with VueReal tostudy and analyze the efficiency performance of its LEDs with the purpose of elucidating the factors behind theefficiency droop behaviour. The obtained knowledge will then be utilized for developing new device designand/or process flow that will mitigate this undesired effect. The collaboration will enable VueReal to solvethis problem, and thus create knowledge-based technology products that will enable Canadian manufacturers topenetrate the emerging market for augmented/virtual reality (AR/VR) displays for the consumer electronicsmarket. The successful outcome will produce a manufacturing capability based on existing micro-fabricationtechniques will create a transformational technology that can leverage existing Canadian infrastructure in theconsumer electronics sector.

Vuereal是一家位于滑铁卢的公司，从事下一代超高分辨率的发射式显示系统。更具体地说，VueReal正在开发一种新颖的集成技术，该技术可以在各种结构和形式中创建适用于各种便携式应用程序，例如手机，头部显示器，Pico-Projoctors和Smart，以此来创建。手表以及虚拟现实（VR）和演出现实（AR）设备。预计微型展示市场将从目前的2.25亿美元增长到2025年的19.9亿美元，这是54％的复合年增长率。因此，Vuereal在这个新兴市场中成为设计师和制造商的主人公角色。但是，Vuereal目前正面临Actallenge，因为当设备尺寸降低到很少的微米时，其LED的效率会降低，这是微型LED显示器所需的尺寸尺度。这种效率下垂的性质和原因仍然未知。在这个项目中，滑铁卢大学的阿齐兹小组将与Vuereal Tostudy合作，并分析其LED的效率性能，以阐明效率下垂行为背后的因素。然后，获得的知识将用于开发新的设备设计和或过程流，从而减轻这种不希望的效果。该协作将使Vuereal能够解决问题，从而创建基于知识的技术产品，从而使加拿大制造商能够为消费电子市场的增强/虚拟现实（AR/VR）展示提高新兴市场。成功的结果将基于现有的微型制造技术产生制造能力，将创建一种转型技术，该技术可以利用Thecmosumer Electronics部门的现有加拿大基础设施。
