Display & 3D display
The use of display- and 3D display technology offers a great number of possibilities that will only grow in the future. Smartphones, computers, glasses and others will largely take advantage of the many possibilities that the display- and 3D display technology give, and only the future can tell how we will use optical applications like this in our daily lives.
We provide a variety of advanced optical elements and services for modern and future display applications. Read on to learn more.

Use of Display & 3D Display
There are different types of displays and 3D displays. In the following, we will give you an explanation of the different types and how we can help you create the different displays.
Transparent displays are displays where the real world is visible through the display. Well known applications within that use transparent displays are head-up displays (HUD), and head-mounted displays (HMD). Transparent displays are made for augmented or mixed reality (AR/MR). These displays are often based on planar waveguides.
NILT can provide masters for the nanostructured optics that is are necessary for directing the image from the light engine to the planar waveguide and again out of the waveguide to the observer.
3D displays let you view, and share 3D conceptions of the real world. This can for example be done with holographic or light field displays. Advanced nanostructured optics are needed for the creation of a light field that is similar to the light field emitted from the original physical scene.
NIL Technology provides structures and optical components needed for the accurate control of light from 3D displays.
Light Field Display
A light field display uses a microlens array to split images into individual light rays. The display imitates the light field that originated from the original physical scene and creates a light field directly in front of the viewer’s eyes, using adequate encoding of the image shown. This makes the viewer able to focus on various depths of a scene.
An ordinary 2D display includes only lateral information in the display plane to create an image. In a light field display, the lateral position and the direction of the emitted light need to be controlled. This can for example be accomplished with a display screen, where the pixels are further divided into sub-pixels that emit light only in specific directions. In contrast to stereoscopic displays, light field displays can support simultaneously consistent binocular disparity, accommodation and convergence.
NILT offers a variety of optical components and services for use in display applications. Products and services include design to optical requirements, masters and replication of microlenses and microlens arrays (MLA); binary, blazed and slanted gratings; anti-reflective structures; multilevel diffractive optical elements (DOEs) and multilevel diffractive lenses.
We can also provide masters for antireflective structures and microlens arrays (MLA) for 2D displays
