WORLD'S FIRST HIGH RESOLUTION LED WALL WITH ANTI MOIRE FILTER IN NORWAY
SiliconCore has completed the installation of the world’s first high resolution LED video wall with anti moiré filter in Norwegian Broadcasting Corporation’s (NRK) new state-of-the-art studio, with the first live studio broadcast taking place on Monday 18th August.
NRK is Norway’s public service broadcaster and largest media house, comprising of three TV channels, three radio stations and a plethora of Internet, podcast and phone programmes. The station wanted to create the next generation of broadcasting studio with the main challenge for all technology providers being to eliminate moiré patterns during camera zooms and for off axis viewing angles. During live interviews, presenters in the studio and those on screen were also required to have the same true to life colour match.
Moiré patterns are a well known and common problem when using LED within a broadcast environment, usually combated by fixed camera angles and shots. NRK wanted a high resolution LED video wall without these moiré patterns to provide full flexibility in the studio, something that has never before been accomplished.
Steve Scorse, VP EMEA for SiliconCore explained:
“We worked with Display Systems, our Norwegian partner over a period of 12 months of extensive testing and benchmarks to develop a unique solution that removed all moiré patterns on a high resolution LED video walls. Not only does this groundbreaking solution provide any broadcast studio with new levels of freedom and creativity, as an added bonus it also enhances contrast and black level in the picture.
“This was a really innovative project to be involved in and the developments that have been made with regard introducing anti moiré technology to LED displays we are now able to offer to the wider market as a broadcast solution.”
The solution is based on the new 2.6mm Peony Broadcast LED panel from SiliconCore with its new Common Cathode driven approach, with the following specifications:
– 13.5 metre long by 2 metre high
– Designed in an “L” shape (could be almost any shape or size)
– Pixel pitch 2.6mm
– Resolution 4992 x 768 pixels
This makes for a striking back drop and live correspondence screen, with a footprint of over half the studio back wall.
The display runs along two sides of the studio in a ‘L’ formation and is a flagship feature, taking up a significant portion of the approx. 30 metre long back wall. Content wise, it is split into four different sections with each able to be used for different presenting functions, from a backdrop for images, statistics and highlighting key points of story through to a live correspondence screen for interviews.
SiliconCore has revolutionised the LED display industry by developing a new way to drive the LEDs using Common Cathode Technology, replacing the traditional Common Anode approach. The Common Cathode Technology design is a much more efficient at generating a given brightness for a given amount of power, ensuring that less power is wasted as heat, reducing power consumption and increasing the lifespan of the display. The end result of displays using Common Cathode Technology is a beautiful display with market leading total cost of ownership.
Kjetil Edvardsen, CEO for Display Systems explained:
“At first, the task given from NRK seemed almost impossible. We had a great partner and LED product through SiliconCore and its new 2.6mm Peony broadcast display. However, on such high-resolution LED video walls, removing moiré had never been accomplished.
“The development of a anti moiré filter was very difficult, as each possible solution to a challenge seemed to create whole new sets of challenges. However, working closely with SiliconCore, and especially their CTO Nedi Nadershahi, we managed to develop a solution that not only satisfied NRK’s moiré removal requirements, but also added features that greatly improved contrast and black level with absolutely no reflections from studio lights.
“NRK is breaking new ground with this state-of-the-art studio. Not only with regards to this one of a kind LED without moiré, but also the creative backdrop design and use of technology. This innovative, groundbreaking and flexible solution for removing moiré opens a new set of possibilities for the Broadcasting Industry worldwide.”
