QST Holodeck 1.9i LED Tile

Designed specifically for LED virtual production and ICVFX, the Holodeck sets a new standard for LED VP imaging.

This is by far the best LED VP tile we’ve seen to date, and its not really a surprise when you understand its development history. The company behind it – QST LED – set out to manufacture the LED VP tile that Cinematographers, VP Supervisors, and Directors all wanted, instead of the event quality LED tiles they were being offered.

QST knew the LED tile specification that would be needed to deliver true cinematic imaging quality, but they had to develop and refine multiple technologies over time to create a VP tile that delivered on the requirement. That process started in 2017 and today, 6 years later and 5 product generations on, we have the Holodeck.

As well as having a remarkable specification, the Holodeck also uses two of the newest LED tile technologies; common cathode circuitry and Flip Chip 1010 LEDs. These two technologies deliver improved imaging, reduced power drain, and increased resilience. Flip Chip LEDs are also less costly to produce compared to the more common SMD 1212 LEDs, meaning Holodeck isn’t price prohibitive.

The Holodeck 1.9i comes in two versions, each using a different IC driver chip, with the 7,680Hz 180fps version costing approximately 8% less:

QST Holodeck 1.9i
  • Max Scan Rate: 7,680Hz is typical for VP, 15,360Hz is the highest to date
  • Scan Ratio: as large a fraction as possible. 1/12 is typical, 1/8 is the highest used in VP
  • Max Frame Rate: high as possible. 140fps is typical, 240fps (sometimes quoted as 251fps) is the highest to date
  • %DCI-P3 Coverage: as close to 100% as possible, 99.7% is the highest to date
  • %Rec2020/BT2020: as close to 100% as possible, >90% is the highest to date
  • Reflectivity: as close to 1% as possible, <3% is the lowest to date
  • Viewing Angle: as close to 180/180 as possible, 170/170 is the highest to date
  • Brightness: high as possible. 1,000-1,200nits is the minimum for VP, 1,500nits is the highest to date
  • Contrast Ratio: high as possible. 8,000:1 is typical for VP, 16,000:1 is the highest to date

Quality

LED Type: Flip Chip 1010 technology in the Holodeck ensures more resilient electronic contacts compared to more widely used SMD 1212. This increases the life span of the LEDs and reduces faults such as dead pixels.

Circuitry Type: The common cathode circuitry in the Holodeck drives each LED RGB emitter at the optimum voltage, delivering higher quality light output.

Tile Frame Material: Holodeck’s Magnesium-Aluminium alloy frame is designed for strength and heat dissipation; it can be stacked 36 tiles (18m) high.

Sustainability

The QST Holodeck 1.9i represents a watershed moment in LED virtual production. Now there is a LED tile that delivers true cinematic image quality, a tile which is built for electronic as well as stacking resilience, and a tile which significantly reduces the carbon footprint of LED virtual production.

Is there a better LED VP tile on the market today?
