Quantum dot-enabled micro LEDs displays for future virtual-reality and flexible devices

增强现实和虚拟现实(VR)设备正开始在这个信息时代扮演着改变游戏规则的角色，并已经为技术和制造业带来了新的机遇和挑战。VR有助于尽可能多地捕捉多感官体验，克服人体的限制。在不久的将来，VR和近眼设备将极大地惠及(I)航空航天、(Ii)国防、(Iii)医疗、(Iv)交通、(V)娱乐和(Vi)显示隐私领域。预计到2022年，增强和虚拟现实市场的总和将超过1500亿美元。这些器件对要求微米级像素间距、低功耗、高亮度、高色域、快速响应和低成本的显示器提出了高性能标准。现有的显示器制造技术要么不兼容，要么成本过高，无法满足微米级像素化的要求。为了解决这些问题，VueReal Inc.和滑铁卢大学的研究人员将开发一种高效率、低成本的微型LED制造技术，该技术既具有创新性，又在该领域处于领先地位。该项目将开发一项新技术，包括微像素化和墨盒转移、固体印刷键合技术、采用无毒材料的量子点启用色彩图案化工艺，以及面积高效、低功耗的智能驱动电路，使微LED阵列能够为未来的近眼、虚拟现实和灵活设备应用提供一种新颖、高效和高成本效益的显示技术。

Augmented and virtual reality (VR) devices are starting to play a game-changing role in this information ageand already present new opportunities and challenges to the technology and manufacturing sectors. VR helpscapture as much multi-sensory experience as possible, overcoming the limitations of human body. VR andnear-eye devices will strongly benefit (i) aerospace, (ii) defense, (iii) medical, (iv) transportation, (v)entertainment, and (vi) display privacy sectors in the very near future. Combined augmented and VR marketsare predicted to exceed USD150 billion by 2022. These devices impose high performance standards for thedisplays demanding micron-scale pixel pitches, low power consumption, high brightness, high color gamut,fast response, and low cost. Existing display manufacture technologies are either incompatible orcost-prohibitive to meet the demands of micron-scale pixilation. Addressing these issues, VueReal Inc. andresearchers from University of Waterloo will develop a high efficient, low-cost, micro-LED manufacturingtechnology that is both innovative and ahead in the field. This project will develop a novel technology formicro-pixelation and cartridge transfer, solid-print bonding technology, quantum dot-enabled color patterningprocesses employing non-toxic materials, and area-efficient, low power driving smart circuits to enable themicro-LED arrays to yield a novel, efficient, and highly cost-effective display technology for future near-eye,VR, and flexible device applications.
