03 Application Scenarios and Selection Recommendations
In aircraft cabins, displays in different locations serve distinct functions, necessitating tailored technical solutions for optimal performance.
Seatback Screen Selection Recommendations
As the most directly interacted display for passengers, seatback screens require a precise balance between visual experience and space utilization.
Size and Resolution should be differentiated by cabin class. A 12.1-inch HD screen is recommended for economy class, providing basic entertainment while controlling costs. Business and first class should utilize 15.6-inch Full HD or 4K screens for a superior visual experience.
Touch Technology selection should consider the usage scenario. Projected Capacitive (PCAP) technology supports multi-touch and gesture operations, catering to modern interactive needs. Infrared touch, conversely, offers advantages in durability and operation with gloves.
Integrated Design is the prevailing trend for modern seatback screens. Ultra-slim designs allow displays to integrate seamlessly into cabin interiors without occupying excessive space.
Headrest Screen Selection Recommendations
Headrest screens prioritize space efficiency and energy performance, aiming to maximize functionality within a confined area.
Size Optimization is the primary design consideration. 9.7-inch or 10.1-inch screens with HD resolution are recommended to provide sufficient display detail within the limited space.
Slim and Lightweight Design directly impacts installation feasibility. Select displays with a thickness controlled within the 8-12 mm range and a weight not exceeding 500 grams to avoid excessive burden on the headrest structure.
Power Consumption Control is particularly critical for headrest screens. Utilizing low-power LED backlights and efficient power management, the typical power consumption per screen should be controlled within 5-8W to alleviate the load on the aircraft's electrical system.
