LG LBCK039-GN 3.91mm Pixel Pitch LED Ceiling LED Display for Virtual Production

Product Overview

The LG LBCK039-GN is a 3.91 mm pixel-pitch ceiling LED display cabinet engineered for virtual production studios. It pairs a high 5,000-nit calibrated brightness with 14-bit PQ/HLG processing for broadcast-grade overhead lighting and content. Each cabinet measures 500 x 1000 x 66.05 mm with a 128 x 256 resolution built from a 2 x 2 module layout. Native compatibility with Brompton processing makes it a fit for established broadcast and VP workflows.

Product Description

This LBCK-series ceiling cabinet uses 250 x 500 mm modules at a 64 x 128 module resolution, with a die-cast magnesium chassis weighing 12.5 kg per cabinet (24.9 kg/m²). Physical pixel density is 65,536 pixels per square meter and cabinet flatness is rated to plus or minus 0.3 mm. Modules attach with positioning pins and magnets and are removable with a dedicated tool from either the front or rear, depending on the configuration chosen at order. Calibrated brightness reaches 5,000 nits across a 2,000 to 11,000 K color temperature range with a 6,000:1 contrast ratio and 160-degree horizontal / 155-degree vertical viewing angles. Power runs on 100 to 240 V at a 50/60 Hz frame rate with a 3,840 Hz refresh rate; maximum cabinet draw is 300 W. The cabinet operates from -30 to +45 degrees C and carries CE, FCC, and ETL certifications plus RoHS compliance. The series is driven by a Brompton SX40 controller.

Typical Applications

The LBCK039-GN is purpose-built for film and broadcast virtual production studios, where it forms the overhead ceiling plane of an LED volume to provide interactive lighting and reflections for in-camera VFX. Its high brightness and Brompton compatibility make it appropriate for VP stages, broadcast sets, and commercial production studios. The lightweight magnesium cabinet eases overhead rigging in these environments.
