After reviewing several other options, Chinese LED cinema screen manufacturer Unilumin has selected Macroblock’s MBI5850 as its display driver. The MBI5850 features 16-bit grayscale with smooth low grayscale performance, and a 3,840Hz visual refresh rate that the company says is designed for high-resolution LED displays.
The Unilumin LED cinema screen was jointly developed by China Research Institute of Film Science and Technology, China Film Company, and Unilumin Group. Unilumin’s LED screens, UC-A41 and UC-A21, have been installed in The China Film Cinema Bei'ao, Beijing.
One of those screens measures16.384 meters by 8.64 meters. The companies say it is currently the world's largest DCI-certified 4K LED cinema display. Unilumin received its certification from the Digital Cinema Initiative last June.
Dedicated in the LED display industry for decades, Macroblock’s common cathode driving architectures are patented in the U.S., freeing them from the application and market restrictions of legacy patents to achieve 16-bit grayscale and high refresh rate image quality on common cathode LED displays. These patented technologies have been applied in Macroblock’s common cathode LED display driver ICs, MBI5754 and upcoming new products, which also comply with the rigorous DCI specifications for high-end cinema market.
