| This backlight is mainly used for air conditioning line controllers and various floor heating and water heating line controllers products. | |||||||||
Equipped with S206 high-brightness white LED beads, delivering 300 CD/M2 brightness—visible even in direct sunlight (e.g., window-mounted AC units).
Uniform backlight distribution: No hotspots, ensuring consistent visibility of temperature, fan speed, and mode icons.
Low-voltage drive (2.7V~3.0V) reduces power consumption by 25% compared to 5V backlight modules, aligning with energy-saving HVAC trends.
Mercury-free LED technology: Complies with global environmental standards (RoHS, LEED), avoiding pollution during disposal.
FPC interface supports flexible PCB integration, fitting curved or slim AC controller designs.
AA area size (69.8mm X 45.5mm) can be adjusted to match different controller panel sizes (e.g., wall-mounted vs. portable ACs).

Grand View Research reports the global HVAC system market will reach $382.66 billion by 2030 (7.5% CAGR, 2025–2030). Key drivers for the JR-SD7858AW4:
Global AC shipments: 221 million units in 2025 (12.9% YoY growth), with 90% requiring backlit controllers.
Smart HVAC adoption: 65% of new ACs feature digital controllers by 2024, demanding high-quality backlight modules.
European/Asian demand: Europe’s floor heating market (40% global share) and Asia’s portable AC growth drive need for custom controllers.
Tested with BM-7 professional optical equipment: Ensures brightness, contrast, and color consistency across all modules.
1000-hour high-humidity (90% RH) testing: Prevents backlight fogging in humid climates (e.g., Southeast Asia).
LED backlight lifespan: 50,000 hours (equivalent to 10 years of 14-hour daily use), matching AC unit lifespans.
Simple driver circuit: Reduces component failure risk, lowering AC controller maintenance costs.
