Liying technology Co.,Ltd is located in Shenzhen, China. It's a high-tech company with design and market. VCool polarized 3D projector adopts innovative 3D technology called lossless luminance polarized 3D technology. That is design for 3D, and compatible with 2D. The optical system with this technology has no energy loss after converting 2D to 3D. Also, it has other excellent features, such as strong peripheral compatibility, expansibility, and not using polarizer glasses before the project lens. So, it can achieve higher brightness and lower power. The overall technological makeup is optimized for 3D, so it exceeds the existing polarized 3D display products.
