剑桥大学的Microdisply突破旋转POROTECH被设定为加速增强现实（AR）眼镜的长期可持续的商业化。微LED先驱已基于天然红氧化铟镓（INGAN）的基于本地红铟镓（INGAN）创建了世界的第一个微透视 - 斜对角线有0.55英寸，分辨率为960×540。
Until now, it has only been possible to produce blue and green microdisplays using GaN-based light-emitting devices – with red emission relying on devices based on aluminum indium gallium phosphide (AlInGaP). But AllnGaP struggles at the small pixel sizes required by AR, so there is a drastic efficiency drop as the device size decreases. And, to produce a full-color display, the light from different panels has had to be combined.
POROTECH突破意味着，首次使用单个工具分关线制造所有三个发光元件 - 并且它基于不同的材料结构去除混合装置的复杂性。
“AR技术被设定为游戏更换器，微LED对AR界面的进步特别重要，”Porotech Ceo和Conttong朱博士博士说。“在传统的液晶显示器（LCD）中，图像是从白色背照明模块调制和过滤光的结果。因此，面板创建的大部分光被显示器的工作原理浪费。除了这种低效率之外，LCD显示屏的各种滤波，扩散和调制级均对最终显示器的重量施加限制。
另一方面，“发光展示技术仅生产它们所需的光 - 允许最终设备潜在地实现更高的效率。基于无机半导体的自发射显示器也可以以单片方式生产，使它们比传统的LCD或有机半导体显示器更容易缩放 - 允许更小，更轻，更亮，可靠的高分辨率显示器。“
到目前为止的绊脚石是需要公司mbine light-emitting devices based on different material structures. One solution has been the use of prisms – but this is a relatively large and bulky approach. Stacking emitting layers on top of each other is another option but this results in the light emitted by each color coming from a different depth in the display – complicating the design of the optics and requiring very high precision in both the pitch of the LEDs in each display, as well as the alignment of the various layers in the structure. Combining LEDs from different materials onto one panel horizontally is an alternative approach – but this requires very high precision in placing each individual LED element and other optical components.
“Porotech’s new class of porous GaN semiconductor material is now redefining what is possible – enabling the creation of efficient and bright native red InGaN micro-LEDs and microdisplays,” said Dr Zhu. “This has been the missing piece of the puzzle until now. As well as reducing costs, the bright native red can push the maximum achievable wavelength to 640nm and beyond – a first for microdisplay visualization. Our breakthrough is now set to accelerate the commercialization of AR glasses as well as heralding a new era of brighter, sharper, more vivid microdisplays for products such as smartphones and smartwatches.”
