Nanjing Lopu said that the fully sound-transparent LED movie screen achieves four "alls", namely, full sound-transmission: an extremely thin sound-transparent display panel with a very high perforation rate, achieving complete sound-transmission from back to front; full sound-transmission: hundreds of square meters of LED display screen from top to bottom , from left to right, there are sound-transmitting holes at any position; fully anti-reflective: hundreds of square meters of perforated screens such as sound-absorbing baffles, which can absorb and muffle sound; fully compatible: the LED display is compatible with stereo, X.1 channel sound reinforcement, and is compatible with Dolby Atmos ATMOS, DTSX, etc.

Information shows that Nanjing Lopu was founded in 1988 and is a subordinate unit of the 14th Research Institute of China Electronics Technology Corporation.
