Edgeless Display Optical System Design for Total reflection mirror and display array

Recently, the number of requests for development related to displays is increasing. There are various developments for display development requests, there are various developments. In case of this development, it is design of edgeless display optical system through total reflection mirror and display array.

Usually, it is implemented through a lens arrangement to achieve an edge through an array of displays. However, there were many optical limitations in this development request because it was a development request using a total reflection mirror.

To overcome these optical limitations, FresnelFactoryKorea conducted primary optical design and analysis through its optical design program. It was also designed to change the angle and position of the mirror in the 3D design program, where the screen reflected in the mirror was designed to make the bezel invisible like a single screen.


Below is a picture of the optical design phase.

Since optical design program does not have an eye setting function, we designed and analyzed by adding lenses and receivers that act as eyes.

Below is a picture of 3D design using the 3D design program.

To reduce the tolerances of display array and mirror as much as possible, we conducted mold-level tolerance management for the parts shown in the picture.

Below is a view of the manufactured equipment.

In this development request, FresnelFactoryKorea proceeded from optical design using optical design program to instrument design using 3D design program to test after production.

FresnelFactoryKorea is a professional optical company that designs and manufactures optical systems with specifications that customers want through optical simulation programs.
