New development of letinar in Korea: single lens 4.55G, light efficiency up to 10%

6 month 24 Riqingting.com reports , according to Display Daliy reports , South Korea AR Optical module manufacturer LetinAR Two new developments have been made recently ：1, The injection molding process greatly reduces the weight of the lens ;2, new PinTILT technology , Light efficiency is 10%.

simply ,LetinAR It can be regarded as an array optical waveguide scheme based on small holes , Because it involves geometric optics , No dispersion , Therefore, it can ensure visual comfort .

meanwhile ,LetinAR Our plan requires the use of plastic substrates , Not glass , In contrast, the refractive index may have some influence , The refractive index of plastic is 1.5-1.6, Glass can achieve 1.9-2.0 Level . Of course , The advantage of plastic is that it can be lighter , It can also integrate traditional vision correction optical schemes , The lens size can be 6cm×4cm size .

LetinAR tell Display Daliy, The weight of the latest module is small 4.55g.

PinTILT Optical structure

In addition, in optical technology LetinAR Adopted PinTILT technology , It's characterized by 2 Sub total internal reflection and an internal mirror structure .LetinAR Express , The light effect can reach 10%, Monocular power consumption 0.2W, Compared with the optical waveguide scheme, the optical efficiency is higher , The power consumption of the same eye-catching brightness is also lower .

At present, it has passed Micro OLED Module implementation 1080p Resolution display （0.5 Inch ）, Support single item 、 Binocular design .LetinAR Also developing evaluation suite , test 0.23 Inch Micro OLED The effect of （ Resolution or 640×400）,FOV by 22 degree .

Up to now ,LetinAR Already have close 50 Employees , We have established our own optical module production center . meanwhile , It is planned to set up a factory in the United States for production .
