ROI Calculation Logic

Thinning the device could reduce material, transport, and installation costs by approximately 15%. For example, assuming a current product manufacturing cost of $2,000/unit (AI est.) and annual production of 30,000 units, a total cost of $60M (AI est.) could see an annual cost reduction of $900K (AI est.). This differentiation could also create new product categories, generating additional sales opportunities of several million USD (AI est.).

Speed to Market
6× faster than in-house development
This technology achieves thinness by combining existing display components—multi-view display, point light source array, and diffusion screen—in an innovative structure. The underlying optical principles are established, and the demonstration phase is presumed complete. Therefore, adopting companies could significantly reduce the time to integrate into manufacturing lines and product launch compared to starting R&D from scratch. This could shorten lead time by approximately 2.5 years, contributing to early market entry and competitive advantage.
