Complex sheet structure and cover lens assembly
摘要:
A complex sheet structure includes a base plate, a microstructure layer, and a shielding layer. The microstructure layer is formed on the base plate and has a first side and an opposite second side. The microstructure layer has a plurality of prismatic structures, and the base plate touches the first side of the microstructure layer. The shielding layer covers the second side of the microstructure layer and contains a low light-transmittance material.
