ITRI LCD polarizer film avoids toxic solvents, saves production costs

October 11, 2011 — Taiwan’s R&D-focused ITRI (Industrial Technology Research Institute) developed an environmentally friendly polarizer protective film, HyTAC, for consumer-sector LCD displays.

The materials and production process cut down on pollutants and environmental harm by 50%, ITRI reports. This also makes LCD manufacturing safer for human operators. HyTAC eliminates dichlormethane and methanol from TAC film production.

LCD transparency and stability are improved with HyTAC, and production costs are lower. The organic and inorganic silicon dioxide nano hybrid material replaces toxic production solvents. Avoiding diclormethane reduces the production equipment required, especially exhaust recycling installations. The result is a highly transparent polarizer film with a zero retardation optical property that suits new-generation IPS Mode LCD displays.

ITRI has licensed this technology to domestic manufacturers for mass production process development. ITRI is transferring the technology to TacBright Optronics Corp. (Taiwan) for exclusive distribution. HyTAC technology may be licensed out in the future.

ITRI has applied for six patents for HyTAC, three of which have been granted.
