320×160mm P2.5 SMD2121 indoor LED screen module


High Definition Indoor LED Screen Solutions

P2.5 indoor LED module is a kind of SMT LED display panel and is mainly used for indoor display purposes. The P2.5 LED panel consists of thousands of LED lamps, a few driver chips, resistors, capacitors, a PCB board, and a plastic kit. Because each LED pixel is spaced 2.5mm apart, it is also known as P2.5 or P2.5mm LED panel in the LED industry, with the P standing for pixel. P2.5 indoor LED display module comes with 160000 dots/square meter pixel density, high grey scale, and mid-level brightness to offer it the ability to meet a wide variety of LED projects that require HD quality, and make it an incredibly versatile yet affordable LED video wall solution for rentals, installs, advertisings, media, and events.

This module is soldered by industry-leading SMT LED technology and designed with RGB color mode to achieve red, green, blue and any visible light color by controlling the current. In simple words, it is a full-color display module that can offer all colors on the spectrum while keeping authentic and natural. In addition to rich color, P2.5 can provide up to 3840Hz refresh rate, which gives it the ability to reproduce the picture color clearly without flickering or ghosting effects. It answers a series of needs that many indoor video walls will require: an affordable price, excellent brightness output, and bright, consistent image quality.

LED module brightness


P2.5 LED Panel provides the most comfortable brightness (about 1,000Nit) for indoor viewing, ensuring that the P2.5 LED display delivers the best viewing experience in indoor surroundings.

SMD Encapsulation

Employing the innovative SMD 3in1 encapsulation, each pixel is a marvel of engineering, harmoniously blending red, blue, and green LED chips to create an uninterrupted, dynamic visual canvas.
LED module driver IC

Driver IC

Made with first-class driver IC ICN2038S, ICN2153, etc, allowing you to maintain display quality, and output performance, and get eye-catching visual effects.
Black Frame Mast LED module

Full Black Techology

Enhanced by a full black LEDs, mask and PCB frame, the P2.5 diminishes light reflection, elevates contrast, and boasts exceptional grayscale versatility, perfectly tailored for low-brightness environments.

Wide Viewing

The P2.5 indoor LED module provides up to 160 viewing angles to minimize viewing blind spots and maximize visual coverage.
LED module contrast ratio

High Contrast

Exhibiting a grey level of 14 bits and a contrast ratio of 5000:1, the module orchestrates a visual symphony of nuanced shades and crisp contrast, adding depth and dimension to every frame.

HD Visual Performance

Small pixel distance with only 2.5mm. Lower pixel pitch means higher LED density, higher resolution, and sharper output.

Two Sizs Available

Two different sizes of 160*160mm and 320*160mm for chose.

160×160mm P2.5 SMD2121 indoor LED screen module

160×160mm Series

160mm×160mm series is designed with a 1:1 ratio measurement, delivering up to 4,096 full-color bright LEDs distributed in a panel at 64 rows and 64 columns matrix, bringing extremely high contrast ratio and ultra-high color consistency. This is very similar to our 3mm pitch 192x192mm indoor LED panel, which is also designed in a 1:1 ratio and offers 64 x 64 LEDs, but with a wider distance between the LEDs at 3mm.

320×160mm P2.5 SMD2121 indoor LED screen module

320×160mm Series

The 320mm*160mm series is mounted with 128 rows and 64 columns of LEDs, which means there are up to 8,192 LEDs on each panel.
