A brightness enhancement film integrates pores within prism structures to redirect light paths and improve forward intensity.
A prism unit with a rotationally asymmetric curved reflective surface directs illumination light through integrated optical paths.
A display-integrated fingerprint detection system uses a prism sheet and microlenses to refract near-infrared light for clear image generation.
Multilayered thin film with alternating anisotropic and isotropic layers reflects specific wavelength ranges through position-dependent thickness variations.
