Indoor LED screens are designed to deliver high-definition visual experiences in controlled environments, prioritizing fine-pitch resolution, color accuracy, and low power consumption. Ranging from P0.9 to P4 pixel pitches, these screens utilize SMD 1010/2121 LED chips for precise imaging, ideal for close-range viewing in corporate boardrooms, retail stores, and entertainment venues. Features like black mask technology enhance contrast ratios (up to 10,000:1), while 16-bit grayscale processing ensures smooth color gradients. Slim cabinet designs (30-80mm depth) enable flush wall mounting or ceiling suspension, with front-access maintenance hatches for easy servicing. Integrated thermal management systems operate silently (<35dB), preventing overheating in enclosed spaces. Advanced models support HDR10 and 4K resolution, while interactive variants incorporate touch-sensitive overlays or motion tracking for engaging user experiences. Energy-efficient designs (≤200W/㎡) make them suitable for 24/7 operation in public areas like airports and shopping malls.
