The 3Glasses D2 was a tethered virtual reality head-mounted display developed by 3Glasses, a Chinese VR technology company. Released in 2016, the D2 was one of the first China-developed VR headsets capable of competing with established Western brands. The device featured a 2K resolution display and 110-degree field of view, making it an affordable alternative to premium headsets like the HTC Vive.[1]
History and Development
3Glasses Company
3Glasses is a Chinese manufacturer that emerged as one of the significant players in the Chinese VR market during the mid-2010s VR boom. The company developed multiple VR headsets targeting both consumer and enterprise markets.
D2 Vanguard Edition
The D2 Vanguard Edition was released as an upgraded version of the original D2, featuring improved specifications and broader compatibility.[2]
US Market Entry
3Glasses brought the D2 to the United States market, making it one of the first Chinese-developed VR headsets to officially launch in Western markets.[3]
Design and Hardware
Display System
The D2 featured a 5.5-inch TFT-LCD display with notable specifications:
- Resolution: 2560 x 1440 (2K)
- Pixel Density: 534 PPI
- Refresh Rate: 60 Hz
- Latency: Screen response time less than 13ms
Field of View
The headset offered a 110-degree field of view, comparable to the HTC Vive, providing an immersive viewing experience.
Optical System
The D2 used double non-spherical lenses with special coatings:
- Anti-blue light coating for reduced eye strain
- Anti-fogging treatment
- Adjustable to user's sight
- Compatible with eyeglasses
Weight
At approximately 246 grams, the D2 was notably lightweight for a tethered VR headset of its era.
Tracking
The D2 utilized 3DoF (three degrees of freedom) tracking, detecting head rotation but not positional movement. This was a known limitation compared to 6DoF tracking systems like the HTC Vive's Lighthouse.
Controls
The headset included:
- Touch field on the side panel
- Multiple control buttons
- Compatible with third-party motion controllers
Connectivity
Video Connection
- DisplayPort 1.2 or higher
Data Connection
- USB 2.0 or higher
Software Platform
SDK Compatibility
The D2 was compatible with:
- 3Glasses proprietary SDK
- Oculus Rift DK1 SDK (enabling compatibility with some Oculus content)
VRSHOW Platform
3Glasses developed its proprietary content platform called VRSHOW, providing native content for the D2.

Limitations
No Positional Tracking
The D2's 3DoF tracking could not determine the user's position in a room, limiting room-scale VR experiences.
Display Technology
The TFT-LCD screen, while offering high resolution, had higher persistence compared to AMOLED displays, which could affect image clarity during rapid movement.
