P4 = The King of Cost-Effectiveness for Indoor Engineering Projects | The Go-To Solution for Medium-to-Long-Distance HD Displays
While its clarity is slightly lower than that of P2.5, P2.0, or P1.86 models, its significantly more affordable price makes it the preferred engineering model for medium-to-long-distance viewing environments—such as lobbies, shopping malls, lecture halls, KTV venues, and sports arenas.
Budget-friendly, delivers ample visual performance, and offers stable durability—making it a top-selling choice for large-scale indoor engineering projects.
Pixel Density of 62,500 dots/m²: Ensures sharp text and smooth video playback. Ideal for medium-to-long-distance viewing scenarios—such as the back rows of lobbies, shopping mall atriums, and sports stadium spectator stands—offering maximum value for money.
Powered by high-frequency PWM drivers, the display captures flawlessly on camera—free from scan lines or flickering—making it ideal for use as a background screen in lecture halls, conference rooms, and KTV venues.
Featuring matte-black masks and "Black Lamp" technology, the display delivers deep blacks, high contrast, and vibrant colors with excellent visual depth—lending a premium, sophisticated aesthetic to shopping malls and hotels.
Utilizing universal 320*320mm and 320*160mm modules housed in slim, lightweight die-cast aluminum cabinets, the system supports both front and rear maintenance access. It offers versatile installation options—including wall-mounting, suspension, and floor-standing setups—with minimal seams and exceptional surface flatness.
Rated IP54 for dust and moisture resistance, the system comes with a five-year warranty backed by a nationwide service network. Its modular design ensures that a single-point failure does not affect the entire screen, making repairs simple and cost-effective.
Factory-calibrated pixel-by-pixel to achieve a color difference of ΔE≤3, the display offers an ultra-wide 160° horizontal viewing angle—ensuring that large audiences enjoy consistent, true-to-life colors without any color shift or dark spots.
