Absen Builds Asia’s Largest 8K Ultra HD Virtual Studio

Chinese LED display manufacturer Absen Optoelectronic Co. Ltd has built and launched what it claims is Asia’s largest indoor panoramic LED stereoscopic virtual studio.

Based in Shenzen, Absen says the stereoscopic LED virtual studio is 6 meters high and has a diameter of 24 meters, taking up a total area of more than 700 square meters, and consists of a ceiling screen and a curved screen. The studio integrates LED display technology with a virtual camera system and real-time rendering system.

According to the company, this is the first attempt by China’s film and television market to construct such a structure. Technical challenges included steel welding, load-bearing, ceiling fixing, and connecting the ceiling and backdrop curved screen.

Absen’s LED display makes use of a PWM constant current LED driver, which is designed to improve image display and grayscale level, so that even the darkest textures in a picture are visible. In addition, Absen’s LED display has a high refresh rate, enabling it to quickly respond to a dynamic picture and synchronise with a high-speed camera without leaving any trace of scanning lines. Absen says the technology has allowed it to “surmount many pan-focusing challenges and become an alternative to shooting on location.”

Absen virtual studio LED solutions feature:

  • 10/12bit input and 16bit output with HDR support
  • The ability to work with higher frame rates which can reach up to 144 frames per second, it makes it possible to shoot slow-motion visual effects with over-cranked cameras against LED screens and still retain perfect synchronization between screen and camera.
  • Low latency with frame delays as low as 1 frame
  • A genlock which can lock the processor at the camera shutter to achieve seamless synchronisation of virtual scenes and character movements.
