Poly Film Investment Co. Ltd., a wholly owned subsidiary of state-owned Poly Culture Group Corp. Ltd., formally introduced its internally developed projection system, known as PolyMax, on June 18 at the 16th Shanghai International Film Festival.

About 10 theaters owned by Poly have been equipped with PolyMax screens, according to Liu Jianfeng, Director of Public Affairs at Poly Film Investment Co. Ltd.

Yao Zongchao, general manager of product research and development at Poly, said: "We have achieved a large amount of innovation in technology. For example, the ultra-short, high-definition focal lens we developed means that we can screen a high-definition movie in a comparatively narrow space."

Poly hopes the system will challenge industry giant IMAX Corp.

For IMAX Corp., China remains a fast-growing component of its global business. It completed the installation of its 100th screen in the country last year.
