Breathable and Light-proof: AOTO's SW Series Ceiling Screens Tackles Break Through the 'Heat Dome'
In virtual production systems, high-brightness LED wall displays can accumulate significant heat during extended operation due to their large surface area. Traditional ceiling screens often feature enclosed structures, making it difficult for this heat to dissipate efficiently. If the architectural floor-to-ceiling height of the shooting environment is insufficient, the natural upward flow of hot air and convective cooling will be restricted, further exacerbating heat buildup near the ceiling displays.
This sustained high-temperature environment poses a serious threat to LED ceiling screens. It can accelerate LED aging, intensify brightness decay, cause color coordinate shifts, and lead to output instability and reduced color consistency. Additionally, it significantly increases the risk of LED failure (dead pixels) and thermal malfunction of driver ICs and other electronic components.
These issues directly compromise the image quality and color fidelity essential for virtual production, increase maintenance costs, and may even lead to production interruptions.
Structural Breakthrough in Breathable and Lightproof Design
Unlike traditional approaches that achieve heat exchange by adding perforations or hollowing out structural elements, the SW Series does not compromise optical light-blocking performance in exchange for airflow pathways. In virtual production environments, ceiling screens serve as the reflective surface for overhead key lighting and therefore must possess excellent light-shielding capabilities. A purely “breathable” design often disrupts optical enclosure integrity, resulting in light leakage from the rear, exposure of internal structures, and increased risk of breaking the visual illusion. These issues can interfere with light reflection control and undermine the consistency and clarity of the captured image.
To address this, AOTO’s SW Series Ceiling Screen achieves a breakthrough "breathable and lightproof" technical approach, successfully striking a precise balance between "permeability" and "containment." The solution employs a dual-path collaborative design:
At the thermodynamic level, the internal topology of the SW screen modules is restructured. Low-resistance thermal channels are strategically embedded within individual LED cabinets or between module junctions. These channels enable natural air penetration through the screen, driven by thermal pressure differentials—from high-temperature zones at the bottom to lower-temperature zones at the top—thereby enabling efficient passive cooling.
At the optical level, light-blocking composite materials are seamlessly integrated to eliminate rear light interference, ensuring the visual integrity of the front-facing image during shooting.
This design not only ensures the light-blocking capability and imaging stability of the SW ceiling screen, but also achieves efficient heat dissipation in a restrained and concealed manner, without relying on traditional perforations or added materials, effectively preserving the structural integrity and visual purity of the screen, truly balancing performance and aesthetics.

SW Ceiling Screen Heat Dissipation: Experimental Validation and Results
AOTO conducted rigorous laboratory testing and real-world application verification to quantitatively evaluate the thermal performance of the breathable structure used in the SW ceiling screen. Test data showed that under the same thermal load conditions, the front surface operating temperature of the ultra-large screen using this structure was significantly reduced by 8°C to 10°C. This result directly confirms that hot air is effectively discharged from the front area of the screen, fundamentally improving the operating environment of the core display components, which is beneficial for enhancing the long-term stability and lifespan of the LED elements.
At the same time, monitoring data indicated a noticeable downward trend in the temperatures of internal components such as PCBs and heat dissipation substrates. This demonstrates that not only is the accumulated hot air on the exterior being vented, but the heat generated internally by the screen during operation is also being more effectively dissipated due to internal airflow.
Crucially, temperature monitoring of the suspended area behind the ceiling screen showed an increase of approximately 5°C. This phenomenon provides direct evidence that hot air successfully penetrated the airflow channels within the screen and was released into the rear space, strongly validating both the unobstructed airflow design and the overall effectiveness of the thermal management mechanism.

Multidimensional Enhancement of Equipment Performance and Operational Efficiency
AOTO Electronics' self-developed breathable SW Sky Screen heat dissipation structure, based on precision engineering design and material innovation, provides a systematic solution to the challenge of thermal accumulation encountered in virtual production scenarios, comprehensively enhancing the operational performance and applicability breadth of virtual studio systems.
Firstly, by optimizing airflow channels and heat dispersion pathways, this structure effectively suppresses the temperature rise of display modules during operation, reducing the probability of hardware failures induced by high temperatures (such as dead pixels and driver abnormalities). This significantly enhances system stability and reliability, providing solid support for the continuity and controllability of shooting schedules.
Secondly, regarding image output, the stable thermal management mechanism helps maintain color consistency and brightness uniformity of the LED screen under high-load operation. This ensures that imaging quality does not suffer from color shift or attenuation due to thermal runaway, thereby reducing post-production correction costs and elevating the professional standard of visual presentation.
Furthermore, the structural heat dissipation design effectively delays the thermal aging process of core components, extending the overall equipment lifespan. This indirectly reduces the depreciation rate and the frequency of maintenance and replacement, offering quantifiable benefits for production units in controlling long-term asset operating costs.
Simultaneously, this technology enhances the system's spatial adaptability flexibility. It enables virtual production technology to overcome previous limitations regarding venue height and ventilation conditions, making it suitable for more scenarios and broadening application boundaries.
Finally, leveraging an efficient passive cooling strategy, this solution significantly reduces reliance on active cooling equipment (such as high-power air conditioning). This not only decreases system energy consumption but also optimizes the complexity and cost structure of cooling configurations, aligning with the industry trend towards green filming and energy conservation/carbon reduction.
