LetinAR is a Korean startup founded in 2016 that develops an optical solution for Augmented Reality (AR) Glasses, consisting of LetinAR’s self-developed “Pin Mirror (“PinMR™”) lens” and a microdisplay made by external partners.

Under-par performance of existing optical systems has hardly satisfied users and experts because of their bulky bodies, narrow Field of View, complicated manufacturing process, and inaccurate color expression. LetinAR’s PinMR™ lens is set to replace such displays. The company has applied the “Pinhole Effect” to tiny mirrors, smaller than human pupils, and embedded them with eyeglass lenses. Respective PinMR™ reflects the light from a microdisplay and guides the light into human pupils. Users may view the virtual image from the microdisplay as well as the image from the real world at ease.

With LetinAR PinMR™ lens, smart glasses manufacturers can build smart glasses worn like a pair of conventional glasses. PinMR™ Lens can also show a clear image without inducing dizziness because it is able to extend the Depth of Field (DoF) multiple times. LetinAR aims to break down the technical barriers that have long hindered the commercialization of AR glasses, with its trademarked PinMR™.

LetinAR designs, manufactures, and supplies PinMR™ by on-demand basis. LetinAR plans to supply PinMR™ Lens as a complete module, which consists of PinMR™ lens and a microdisplay from external partners. LetinAR will begin providing PinMR™ Lens samples in 2019, making it possible for smart glasses manufacturers to evaluate the potential of using PinMR™ lens for their own products.
