Indoor P4 LED Display Module


64×32 dot P4 SMD1921 LED display module


Clarity and versatility for indoor visual with 4mm pixel pitch

The indoor P4 LED Module is a high-density, full-color display solution that represents the pinnacle of SMD technology. It is ideal for creating stunning visuals in indoor projects, where image clarity and color accuracy are paramount. The module’s standardized dimensions—available in either 320(W)x160(H) mm or 256(W)x128(H) mm—allow for flexible installation options without sacrificing picture quality. Its precise 4mm pixel pitch ensures high-resolution imagery, making it perfect for locations that require crisp, clear visual content.

Equipped with the latest black LED technology, the P4 indoor LED Module delivers deep blacks and higher contrasts, resulting in more vivid pictures and videos. The integration of sophisticated driver ICs provides reliable control over the LEDs, culminating in a smooth visual performance with a high refresh rate of up to 3840Hz.  A high refresh rate allows P4 to eliminate image flicker and ensure motion scenes appear fluid, making the display suitable for a variety of dynamic environments such as broadcast studios, retail, advertising, stages, churches,  monitoring rooms, and indoor spaces where engaging and eye-catching content is essential.

In addition, The P4 Module is set to shine at a brightness of 600 to 1000 cd/m², which is just right for indoor environments. This low brightness level avoids any discomfort that can come from overly bright displays and ensures that the grey scale performance is high, capturing every delicate detail and presenting a more lifelike image.
