GDC PM-2000A: Passive 3D Simplicity Without the Licensing Strings

The GDC PM-2000A is a standalone passive 3D system designed for digital cinema projectors. It delivers bright, immersive 3D visuals using circular polarization and is engineered for easy installation, low maintenance, and long-term reliability. Unlike some competing systems, it requires no licensing fees and integrates seamlessly into projection booths using silver screens.

System Overview
The PM-2000A supports frame rates up to 60 frames per second per eye and is compatible with screens up to 18 meters wide. It uses a motorized bracket to automatically position the polarizer when a 3D signal is detected, then retracts for 2D playback—no manual intervention required. The system is compact, weighing approximately 1.3 kilograms, and includes adjustable mounting hardware for flexible installation.

Technical Requirements

• Circular polarization
• Silver screen with a gain of 2.4 or higher
• Projector dark time: 650 to 850 microseconds
• Output reference delay: –120 microseconds
• Compatible with most DLP digital cinema projectors

Included Components

• Polarizer unit
• Motorized bracket and support base
• Adjustable mounting brackets
• Extension kit
• Power supply and control interface

Operational Benefits
The PM-2000A eliminates the need for active glasses, IR emitters, or complex calibration. It’s a plug-and-play solution that reduces maintenance and simplifies staff training. With no internal fans or filters, the system is quiet and reliable over long-term use.

Espedeo Passive 3D Glasses
GDC offers a full line of passive circular polarized glasses under the Espedeo brand. These are designed for reuse and are compatible with the PM-2000A system:

• LPG05-E – Standard adult glasses
• LPG06-E – Kids glasses (yellow frame)
• LPG07-E – Kids glasses (blue frame)
• LPG08 – Clip-on for prescription eyewear

All models are lightweight, durable, and optimized for high-contrast 3D playback. They do not require batteries and are designed for hundreds of uses with proper care.

Cleaning and Maintenance

• Wash glasses with warm water and mild soap
• Use microfiber cloths to avoid scratching the polarized lenses
• Optional UV sanitizing cabinets or low-temperature commercial dishwashers can be used for higher-volume operations
• Always allow glasses to fully dry before reuse to prevent residue or fogging

Disposability Options
While GDC does not manufacture single-use disposable glasses, compatible disposable polarized options are available from third-party suppliers. However, the reusable Espedeo glasses offer better long-term value and reduced environmental impact.

Ideal Use Cases
The PM-2000A is well-suited for cinemas transitioning to laser projection, independent theaters seeking a licensing-free 3D solution, and any venue looking to simplify 3D operations without compromising image quality.

Conclusion
The GDC PM-2000A, paired with Espedeo’s reusable 3D glasses, delivers a clean and cost-effective solution for passive 3D presentation. It’s a future-ready system designed for longevity, flexibility, and reliable audience immersion—without the logistical headaches of active systems or third-party licensing.
