What it is.

Aspect Ratios- Tailoring Visuals to Your Needs

16:9: The standard widescreen format, perfect for a variety of media applications, including video presentations and digital signage.

8:9: A more specialized format that offers a nearly square aspect ratio, ideal for applications requiring a balanced display area, such as interactive kiosks.

4:9: Provides a taller display, suited for vertical applications and narrow spaces, enhancing versatility in design and functionality.

QCOB Process

Epoxy Resin Encapsulation: This technology involves encapsulating LEDs in epoxy resin, which enhances their resilience against environmental factors such as moisture, dust, and mechanical impact. This encapsulation helps prolong the lifespan and reliability of the display.

New Optical Heat-Conducting Material: Utilizes advanced materials to improve thermal management, ensuring that the LEDs operate efficiently and remain stable under high loads, thus reducing the risk of overheating and performance degradation.

Enhanced PCBA Strength: The Printed Circuit Board Assembly (PCBA) is reinforced to handle operational stress, providing better support for electronic components and ensuring long-term reliability.

Surface Light Source Display: This feature enhances brightness and uniformity, providing a clearer and more vivid visual experience with consistent light distribution across the screen.

Automotive-Grade Connectors– Precision and Reliability

Adjustable Settings: Supports multiple refresh rates (30/50/60/90/120/240Hz) to accommodate various types of 3D content and viewer preferences, enhancing the flexibility of the display for different applications.

Nano Optical Coating – Superior Protection and Longevity

Waterproof: Protects the display from damage caused by water exposure, making it suitable for outdoor or high-humidity environments.

Dust-Proof: Prevents dust and debris from affecting the display’s performance, ensuring consistent operation and longevity.

Anti-Salt Spray: Provides resistance to corrosive salt spray, which is particularly important in coastal or industrial areas.

High-Temperature Resistant: Ensures reliable performance in extreme temperatures, whether high or low, expanding the range of possible installation environments.

Durable Cabinet Design – Built to Last

Die-Cast Aluminum-Magnesium Alloy: Combines the strength of aluminum with the lightweight properties of magnesium, resulting in a robust yet lightweight cabinet that can withstand physical stress while remaining easy to handle.

Anti-Radiation: Protects against electromagnetic interference, ensuring the display operates reliably in environments with potential radio frequency interference.

Impact-Resistant: Designed to resist physical impacts, reducing the risk of damage from accidental collisions or harsh handling.

Corrosion-Resistant: Prevents deterioration from environmental factors, enhancing the display’s longevity and maintaining its appearance over time.

Silent Operation: Engineered to minimize operational noise, contributing to a quieter environment, which is particularly beneficial in settings such as meeting rooms or performance venues.

Dust-Proof: Further ensures that dust and particles do not compromise the internal components, maintaining consistent performance.

Front Maintenance – Easy Access and Convenience

Easy Access: Enables quick and straightforward maintenance of critical components such as modules, power units, and system cards without the need to dismantle the entire display setup. This minimizes downtime and operational disruptions.

Efficient Assembly – Quick and Reliable Setup

Interlocking Structure: The modular design allows for easy and secure assembly, ensuring that each component fits together precisely and securely.

Module Replacement <2 minutes: Facilitates rapid replacement of faulty or damaged modules, reducing maintenance time and keeping the display operational.
