Tsingcarbo® Black Film for AR/VR Industry

Overcoming Traditional Light Blocking Limitations in AR/VR

The complete AR/VR optical architecture includes core components such as waveguides, lens groups, beam-splitting prisms, and micro-optical engines. Unwanted internal reflected light and scattered stray light can easily lead to washed-out images, insufficient contrast, ghosting and double imaging, and color distortion. Currently, the mainstream industry solutions—optical coating and light-blocking spray painting—both possess significant shortcomings that constrain high-end AR/VR product experience and mass production efficiency:

· Optical Coating: Requires outsourcing to specialized coating factories, relies on expensive vacuum coating equipment, involves complex processes, unpredictable lead times, and high processing costs. Moreover, coating yield is limited—coating curved or irregularly shaped structures is extremely difficult, and interference color aberrations frequently occur, making it unsuitable for mass production.

· Light-Blocking Spray Painting: Suffers from uneven application thickness, insufficient blackness, and poor light absorption. The coating tends to shed powder and flake off easily; the resulting dust can easily contaminate precision optical components, reducing product yield. Additionally, long-term use leads to delamination and aging, compromising durability.

Tsingcarbo® Black Film perfectly avoids the shortcomings above, delivering superior light absorption performance at lower cost, with cleaner processing, higher safety, and greater production scalability—a next-generation AR/VR optical light-blocking solution that replaces coating and spray painting.

Core Application Scenarios of Tsingcarbo® Black Film in AR/VR

1. AR Waveguide Modules

For diffractive waveguides, holographic waveguides, and array waveguide structures, apply 0.4mm light-absorbing film to coupling inclined surfaces, side edges, and areas interfacing with the optical engine to block edge light leakage and interfacial stray reflections, reduce environmental light crosstalk, improve real-world see-through uniformity, and deliver cleaner virtual imagery with sharper boundaries. Manufacturers can apply the film themselves, eliminating the need for outsourced processing and significantly shortening production cycles.

2. VR Headset Optical Systems

Compatible with mainstream VR architectures such as Pancake folded optical paths and Fresnel lenses—apply the film to lens bezels, inner walls of optical cavities, and hard-to-reach corners of beam-splitting structures to absorb internal diffuse stray light, eliminating halos and washed-out blacks, significantly improving contrast and visual immersion. As the film does not shed powder or flake, it keeps precision optical paths clean and enhances product yield.

3. Micro-Display and Peripheral Light Blocking

Cover light-blocking areas on bezels and module gaps of MicroLED and OLED micro-display components; the film's ultra-high blackness provides exceptional shielding against gap light leakage and ambient reflections, suppressing pixel crosstalk and meeting the light-blocking demands of ultra-high-resolution displays. Compared to spray painting, there is no dust contamination; compared to coating, no outsourced production—offering exceptional production flexibility for mass manufacturing.

4. Optical Engine Structural Components and Sensing Modules

Apply to optical engine internal cavities, inner walls of housings, and around tracking cameras and environmental sensors. The film absorbs internal stray light to optimize optical imaging, and its stable material properties enable easy fabrication. Manufacturers can complete the lamination process in-house, eliminating the need for specialized coating equipment and substantially reducing costs associated with optical structure production and tuning.
