DMAX is large-screen cinema format developed in China. It was created in an attempt to challenge the IMAX monopoly which currently dominates China's large-screen film market. The screen size is 20 x 12 metres compared to IMAX's 22 x 16. DMAX was jointly developed by the China Research Institute of Film Science & Technology and the China Film Group Corporation. The first film shown in the DMAX format was in Anhui Province.  As of 2012, over a dozen DMAX cinemas have been opened in China, with ticket prices being lower than its competitor, IMAX.
