Indoor LED modules are designed for controlled environment applications, prioritizing fine-pitch resolution, color accuracy, and low power consumption. Ranging from P0.9 to P4 pixel pitches, these modules utilize SMD 1010/2121 LED chips to deliver crisp imagery for close-range viewing in boardrooms, theaters, and retail spaces. Black mask technology enhances contrast ratios (up to 10,000:1), while 16-bit grayscale processing ensures smooth color gradients. Slim form factors (15-30mm depth) and lightweight designs (≤1.5kg per module) facilitate easy installation and maintenance, with front-accessible components for quick servicing. Integrated thermal management systems prevent overheating, operating silently to avoid disruptions in quiet environments. Advanced indoor modules may include features like HDR compatibility, 4K resolution support, and adaptive brightness sensors, ensuring optimal performance in various indoor settings.
