Displays

This article evaluates some of the strengths and weaknesses of reflective and diffractive waveguides used in augmented reality (AR) optics for smart glasses.

This article describes the variety of optics required for XR (extended reality) devices. For AR glasses, this includes waveguides and other technologies such as birdbath combiners, whilst for VR headsets, solutions include pancake, Fresnel, and aspheric lenses. Across XR devices, different optics solutions are required based on the intended use case, with a variety of factors contributing to the suitability of an optics technology for a specific device. Factors include weight, optical efficiency, image quality, form factor, and cost.

End-of-life equipment from automotives, electric vehicles, e-waste and decarbonized energy technologies are rapidly emerging secondary raw material sources for valuable critical materials. A new report from IDTechEx forecasts that US$110B of critical materials will be recovered annually from secondary sources by 2045, with a combined weight of over 3.3 million tonnes.

The use of quantum dots in displays has made it to high-quality prototypes amongst established tech companies like Samsung, Sharp, and TCL. These semiconductor nanocrystals, the size of just 2-10 nanometres, can enable realistic and high-definition displays for TVs, monitors, and smart tablets.

Modern automotive interiors are evolving at a tremendously fast pace, moving past the mechanical dials and becoming fully electronic. The key attributes of these electronics are noticed by consumers, such as the design of the display, its curvature, brightness, and type of technology, i.e., OLED or LCD, when, in reality, there is a lot more that goes into building the display and assembling the entire unit.

Flying cars might not yet be mainstream, but as developments in the electric and autonomous vehicle industries are making progress globally, the future of driving is set to look very different.

On June 5th, Apple ended years of speculation and finally announced a mixed reality (MR) headset. The US$3499 Vision Pro headset confirmed some expectations and confounded others. IDTechEx has been tracking the mixed, augmented and virtual reality markets since 2015, with reports on headsets and accessories and optics available now and a report on displays for AR/VR soon to be released. This insight into the AR/VR industry and associated technologies provides context to IDTechEx's initial analysis of Apple's headset design philosophy.

A floor that can feel when you fall, a warmth that wanders from room to room with you; could the house of the future take care of you?

Virtual, augmented, and mixed reality (VR/AR/MR) devices promise to revolutionize the way we interact, acting as gateways to the metaverse. Despite these technologies already achieving limited adoption, extensive headset hardware development is required to meet the demands of becoming a ubiquitous computing platform.
