Following in the footsteps of Samsung, LG is getting into the cinema market. Not with projectors, but rather gigantic modular LED screens.
LED cinema screens
Samsung installed the "world's first" LED cinema screen in July 2017 and Sony has been exploring the concept for years.
LG has now installed its first LED cinema screen. It was installed in Taiwan in partnership with Taiwan's Showtime Cinemas and Dolby. The installation includes a full Dolby Atmos system.
By replacing the conventional projector with huge, modular LED screens, LG says that the projector room can be repurposed as seating space.
The company claims that its LED cinema screens have 100,000 hours of lifetime (LED brightness half-time).
- "We are excited about our collaboration with LG Electronics to bring our combined expertise to movie goers in Taiwan," said Jed Harmsen, CPof Cinema & Content Solutions at Dolby Labs. "With the lifelike images created by LG’s LED Cinema Display and the immersive audio delivered by Dolby Atmos, moviegoers will be able to enjoy an elevated and thoroughly captivating cinematic experience."
LED cinema screens can get much brighter than projectors and have far superior contrast to let cinemagoers experience HDR for the first time in cinema. Like OLED, LEDs are self-emitting meaning that each pixel emits its own light for pixel-level luminance and color control.
The price of the system was not disclosed.
