III. Core Integration Technology Solution (For Technical Lead/Integrator Reference)

This solution adopts a modular design, with standardized and replicable integration processes, reducing integration difficulty, ensuring stable operation of the integrated terminal, and taking into account the convenience of later maintenance.

3.1 High-brightness display technology solution (core competitiveness)

3.1.1 High-brightness backlight system (core readable in sunlight)

It adopts high-power industrial-grade LED chips (Epistar/Seoul/Nichia brands, original factory certification available), direct-lit LED strip array design, and is equipped with high-transmittance light guide plate (LGP) + BEF brightness enhancement film + DBEF reflective film, with light output efficiency ≥85%; equipped with constant current IC + PWM dimming driver, current accuracy ±1%, supports high temperature power reduction protection to avoid backlight overheating damage, and ensures brightness uniformity ≤5%.

3.1.2 Reflection Suppression and Full Lamination Process (Key Technology)

The cover glass is made of 3-6mm tempered glass (Mohs hardness 7H), with a triple coating of AG anti-glare, AR anti-reflection, and AF anti-fingerprint, effectively reducing reflectivity to ≤1.5%. Vacuum OCA optical adhesive full lamination process is used to eliminate the air layer between the panel and the cover glass, completely solving the outdoor reflection problem, while improving the display contrast by more than 40%. The frame is made of anti-UV ceramic ink, which will not fade or age with long-term outdoor use.

3.1.3 Touchscreen integration solution (optional, adapted to self-service interaction scenarios)

It adopts an industrial-grade 10-point capacitive touch module with a response time of ≤5ms and an accuracy of ±2mm. It supports touch control while wearing gloves and in the rain, and features strong light anti-interference and anti-mistouch algorithms. The touch panel integrates an IK10 anti-explosion design, which is suitable for outdoor public scenes where people may touch or bump into it. The interface adopts an industrial-grade shielding design to resist electromagnetic interference and comply with European and American EMC standards.

3.2 Thermal Management System (Key to Stable Outdoor Operation)

3.2.1 Heat dissipation design (passive + active combination)

• Passive heat dissipation: The backlight module is equipped with an aluminum alloy heat dissipation backplate + graphite heat dissipation film with a thermal resistance of ≤0.5℃/W, which can quickly conduct backlight heat; the whole machine adopts an aluminum-magnesium alloy shell + heat dissipation fins to increase the heat dissipation area and improve heat dissipation efficiency.

• Active cooling: Built-in NTC thermistor + industrial-grade PWM speed-controlled fan (life ≥ 50,000 hours), adopts "bottom air intake and top air exhaust" air duct design, and is equipped with IP65 dustproof filter + waterproof vent valve, which not only ensures heat dissipation effect, but also prevents dust and moisture from entering.

• Protection logic: When the temperature is ≥65℃, the brightness will automatically decrease to 50%; when the temperature is ≥75℃, the backlight will be turned off; and it will automatically recover after the temperature drops back to a safe range to prevent the device from being damaged by high temperature.

3.2.2 Low-temperature start-up design (essential for cold regions in Europe and America)

With a built-in PTC heating film, it automatically starts heating when the temperature is ≤-10℃ and stops heating when the temperature is ≥0℃. The heating power is ≤30W and the heating time is ≤5 minutes, ensuring that the display screen can be lit up quickly in low-temperature environments, making it suitable for use in cold regions such as Northern Europe and Alaska, North America.

3.3 Structural and protective design (suitable for harsh outdoor environments)

• Overall frame: Made of aluminum alloy/stainless steel with anti-corrosion treatment. 316 stainless steel is recommended for coastal areas to prevent salt spray corrosion.

• Sealing process: Laser welding + Dow Corning silicone rubber sealant is used to ensure IP65 or higher protection level and prevent dust and moisture from entering the equipment.

• Installation structure: Equipped with vibration-damping brackets and wind-resistant design, conforming to the European and American ASCE 7 wind load standard, with wind load resistance ≥120km/h, suitable for outdoor open-air installation;

• Maintenance Design: Adopting a front/rear maintenance modular design, the display module can be disassembled independently without disassembling the entire machine, reducing the cost and difficulty of later maintenance.

3.4 Hardware Integration Specifications (Standardized Implementation)

1. Selection criteria: Based on the terminal size and usage scenario, select a display module that meets the requirements of wide temperature range, high brightness, IP65, IK10 and full European and American certifications, and give priority to products with mature application cases in the European and American markets;

2. Assembly specifications: Full bonding operations must be carried out in a Class 1000 cleanroom to avoid air bubbles and dust residue; the glue application on the frame must be uniform and continuous, without any gaps or overflows, and the curing time must be ≥24 hours;

3. Electrical connection specifications: Power supply uses industrial-grade DC sockets with wire diameter ≥18AWG and withstand voltage ≥1000V; signal interfaces (LVDS/EDP/HDMI) use shielded industrial-grade interfaces to reduce electromagnetic interference; temperature control modules (NTC, fan, heating film) are wired according to specifications and independently controlled to ensure signal stability.

4. Debugging specifications: After integration, a spectroradiometer is required to verify that the brightness meets the standard. A light intensity meter is used to calibrate the light sensitivity of the ALS sensor (±5%). The touch response accuracy is tested in strong light, rainy weather, and when wearing gloves.
