P1.5 LED Module for Indoor
P1.5 LED module is an indoor LED display module with a distance between two LED lamp beads (pixel pitch) of 1.53 mm.
Due to the small pixel pitch, it is suitable for close viewing, with a minimum viewing distance of 1 meter. P1.5 full-color LED modules are usually used in high-end indoor scenes, such as museums, exhibition halls, CCTV, monitoring command rooms, etc.

Stable performance
The lamp beads work well with the IC card, the control system drive is stable, the color difference is small, and the color temperature is balanced, ensuring the overall consistency and visual comfort of the screen.
Front maintenance
The P1.5 LED module can be equipped with magnetic structure or quick-release design, supporting front maintenance.
Long life
Lamp life ≥ 100,000 hours, equipped with 5V high-efficiency power supply, supports overvoltage and overcurrent protection, stable operation and energy saving
High-definition picture quality
P1.5 LED module has small pixel pitch and high resolution, the display is clear and delicate, and can be viewed at a close distance.
P1.5 LED Module Types
SMD P1.5 LED Module
The SMD-packaged P1.5 LED module uses SMD1010 or SMD1212 lamp beads, with a dot pitch of 1.5mm and a pixel density of 444,444 dots/m². It supports ≥1920Hz refresh rate and 14-16bit grayscale level**, and the brightness is generally 600-800cd/m², which is suitable for high-definition scenes such as indoor conference rooms and command centers. This solution is cost-effective, supports front and rear maintenance, has been widely used in standard cabinet structures, is compatible with Nova and Colorite control systems, and is currently the most mainstream P1.5 module format.
COB P1.5 LED Module
COB packaging directly packages LED chips on PCB boards, without the need for traditional lamp beads, and has four major advantages: dustproof, waterproof, anti-collision, and anti-static. The P1.5 COB module has the same dot pitch of 1.5mm, but the brightness is usually slightly lower (500–700cd/m²). The advantages are higher surface flatness and more than 3 times higher impact resistance, which is particularly suitable for public display scenarios that require high reliability and frequent contact (such as education, touch interaction, and museum displays).
HOB P1.5 LED Module
HOB technology is a package enhancement solution based on SMD. It uses semi-solid package colloid to cover the lamp surface as a whole, achieving protection performance close to COB, while maintaining the brightness and maintenance convenience of SMD. Its surface is moisture-proof and fingerprint-proof, suitable for high-traffic commercial display environments or semi-outdoor application scenarios. Compared with traditional SMD, HOB improves the screen's wear resistance by more than 50%, while retaining the structural advantages of magnetic installation and single-point repair of lamp beads.
P1.5 LED Module System Control
The P1.5 LED display screen module supports both synchronous and asynchronous control modes, suitable for different application scenarios.
The module is compatible with mainstream control cards such as Nova, Colorlight, and Linsn, supports multi-module cascading and remote management, and can be connected to the video processor or central control system to meet the needs of large-screen splicing and precise content control.
Synchronous mode
For places with high requirements for real-time playback such as conference rooms and command centers, it is recommended to use synchronous control systems such as NovaStar or Colorlight, which support high refresh rates and multi-window splicing.
Asynchronous mode
Asynchronous control cards such as Grayscale and Colorlight are optional for commercial information release or advertising screens, and support remote content updates via USB flash drives, mobile phone APPs, Wi-Fi or 4G.
Accessories
Power Cable
A 4-pin power cable is provided as standard to connect the module to the power supply.
Receiver card
Famous brand Novastar /Huidu, One receiver card can take 12 modules, 2 wide and 6 high.

P1.5 LED Module Details
FAQs:
What is the pixel pitch of P1.5? What are the viewing distance requirements?
P1.5 means that the horizontal/vertical spacing between LED lamp beads is 1.5 mm, which belongs to a small-pitch LED module. It is suitable for close viewing, and the recommended optimal viewing distance is between 1.5 and 3 meters. It is suitable for conference rooms, monitoring centers, exhibition halls and other places.
What is the expected lifespan and maintenance of P1.5 LED modules?
Indoor P1.5 modules typically last over 100,000 hours. Regular cleaning, avoiding moisture, and proper installation ensure longevity. Unlike flexible or part-front-maintenance solutions, modular front or rear access simplifies support .
What is the difference between P1.5 and P2.5? Why is it more expensive?
The pixel density of P1.5 is nearly 3 times that of P2.5, with clearer display and finer picture, but the production process is more complicated and the materials are more advanced, so the price is also higher. It is suitable for high-end indoor projects that pursue high-definition experience, while P2.5 LED module is more inclined to ordinary information display or long-distance viewing.
