WFT produces custom Tailored Micro-Diffusers (TMD®) with angles that range from 0.5° to 80° . TMD’s are manufactured using surface relief micro-structures that are embossed from holographically recorded master tools. They allow an almost completely tailorable flux output pattern. Below are some characteristics of TMD’s.
- Microstructure Features (~10µm)
- Tailored Field of View
- Holographically Recorded Microstructured Masters
- Centrally Symmetric Patterns
- Elliptically Symmetric Patterns
- Asymmetric Patterns
- High Forward Scattering Efficiency (~90%+)
- Environmentally Stable(-55° to 85° C)

Our TMD® and UTMD product lines accomplish the purpose of traditional diffusers in direct lit and edge-lit Back Light Unit (BLU) systems from Mobil LCD up to large LCD TV/Monitors. However, compared with conventional bead type diffusers, our TMD® in many cases provides the following advantages: higher brightness, better contrast and veiwing angle, less thickness, less layers (such as elimination of diffuser plate and/or prism film. Although BEF and DBEF (which are much more expesive then diffuser) still are the best films for brightness enhancement, our TMD® in some cases can provide a cost effective alternative solution by replacing BEF and DBEF.
TMDs can be easily replicated onto low-cost plastic films. In large quantities, roll-to-roll mass-production techniques insure that WFT’s TMD® costs to OEM manufacturers are well within the range of those for consumer product applications.
