Future of LC lenses
LC lenses working with unpolarized light produces a considerable increase in the optical efficiency. Also switching speed and a reduction in crosstalk should be solved for various applications of LC lenses. LC lenses have many interesting properties for their practical use, for example, small size, lightweight, low driving voltages, low power consumption and transmissive/reflective operation modes. They also have great advantage in a focal length tenability by voltage. For example, a cylindrical LC microlens array has rotary optical power and tunable focal length capability.
Moreover, the lens power of LC lenses is not only electrically tunable, but it can also be positive or negative, which has interest for ophthalmic lenses. Liquid crystal lenses can correct myopia impact.
Commercial glasses based on LC lenses were developed in 2011. They have a switchable focal distance solving the problem for patients that require different types of glasses for different activities.
Lack of affordable, lightweight, high-performance smart glasses has been a barrier to AR’s widespread adoption. They say user-friendly smart glasses will ultimately disrupt the market for phones and tablets. The screens in consumers’ pockets will be replaced by AR interfaces that people put on and keep on.
LC lens capable of tunable focal length makes AR/VR optics into an auto-focusing system.
This technology creates a more vivid, comfortable and immersive 3D experience and relieves negative effects arsing from AR or VR such as blurry vision, nausea and headaches.
Such problems are caused in current VR/AR devices, since virtual objects are displayed at different virtual distances from the user and the device’s static optics system which cannot to synchronize the optical signals with the varying distances.
As mentioned above, future prospects of LC Lens technology are very bright. So, utilizing LC Lens technology and optical technologies of NDIS, we've started advancing into the AR market using Smart glasses with tunable focal length technology.
