Light reflectant surface of expanded polytetrafluoroethylene with nodes and fibrils for backlit liquid crystal displays |
摘要 |
The present invention is an improved material and method for use for providing diffuse reflectivity of light in backlighted visual displays, such as liquid crystal displays (LCD) employed in a wide variety of applications. By employing an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils, the material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible light. Additionally, the material of the present invention provides many properties that have been previously unavailable in highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at relatively thin cross-sections.
