IR light guide for eye-tracking
IR light guide for eye-tracking is a flat light guide that illuminates an eye with infrared light placed on the sides.
DetailsTransparent antenna film
A fine mesh film with high transparency and conductivity. Invisibly fine metal wiring is formed on transparent film to add antenna functionality without compromising the design.
DetailsMLA for microdisplays / sensors
Using microfabrication technologies (ex. EB drawing), can provide Microlenses with nano meter position accuracy.
DetailsDepolarizer
The depolarizer converts linearly polarized light to randomly polarized light.
Improves visibility of display while using polarized sunglasses.
Meta-surface
Meta-surface optics can be thinner and smaller than traditional optics in IR and Visible wavelength region.
DNP's nano-fabrication technology can deliver wider meta-surface products.
Light control film
Light control film can instantaneously switch between clear and dark state with an electrical charge by Guest-Host Liquid Crystal (GHLC) method.
Details
Reflect array
(passive and static)
Can improve UL and DL throughput by compensating for the straightness of 5G/6G radio waves.
The shape of the reflected wave is designed to allow radio waves to reach a wide area.
