2. What is a P2.5 LED Module?

In a word, a p2.5 led module refers to a led panel with a pixel pitch of 2.5mm. P is short for pixel pitch.

What is pixel pitch? 

The pixel pitch directly affects the LED chip density and resolution of the LED display module. It refers to the distance (in millimeters) from the center of a pixel to an adjacent pixel. The dot pitch reflects the spatial distance between two pixels, so a smaller pixel pitch means higher pixel density and higher screen resolution. The picture below shows the difference between the P2.5 led panel and the P10 led panel. It will help you understand the dot pitch more intuitively.


What is the LED module? 

As we all know, the area of a LED video wall can usually reach tens of squares or even hundreds of squares. The giant screen LED screens consist of many LED modules. The modular design facilitates the installation, transportation, and maintenance of the large LED screen. More importantly, you can get large led screen solutions of any size without difficulty. Therefore, P2.5 led panel is popular in the led display industry.

3. Types of P2.5mm LED Module

According to different classification standards, there are many types of p2.5mm led modules. The detailed classification is for customers to better understand the characteristics and application scope of different modules. Only by choosing the right LED module can it give full play to its maximum value. Next, we will introduce you to some different types of P2.5mm led panels.

① Indoor/outdoor p2.5 led panels

Both indoor and outdoor p2.5mm led panels use high-quality led chips like Nationstar, Kinglight. It ensures that the led modules have good display performance.

However, their brightness and the lamp beads used are different. For example, the UNIT indoor p2.5 led panel adopts SMD2121 black LED, while the outdoor p2.5mm led panel adopts SMD1415 type lamp beads. The brightness of indoor modules is between 800-1000nits, and the brightness of p2.5 outdoor modules is over 5000nits.

② SMD P2.5 led modules

The packaging technology adopted is different, and the difference between the modules is also obvious. DIP (dual in-line Package) technology currently has a small market share. UNIT DIP Series RGB Outdoor LED Display Module adopts DIP346 lamp beads. Its brightness exceeds 7000nits.

For small pitch such as p2.5 LED modules, the more popular ones are SMD (Surface Mounted Devices) and GOB (Chips on Board). The SMD P2.5mm led module is made of various materials into lamp beads, and then the lamp beads are soldered on the circuit board using a high-speed placement machine. Because of the mature and stable SMD technology, low manufacturing cost, and convenient maintenance, SMD led screen is very popular.

③ GOB P2.5mm led panel

GOB P2.5mm led module uses advanced transparent materials to seal the led light-emitting device. Therefore, GOB can effectively solve the protection problem of LEDs. At the same time, this material also has super thermal conductivity, which realizes moisture-proof, waterproof, and impact-proof. Compared with traditional LED modules, GOB LED panels can provide a more realistic color and visual appearance.

④ Flexible led panel

Soft LED display panels are often used to make creative LED displays. The p2.5mm flexible led modules have good display performance, high reliability, and the best color uniformity. Different from the traditional fixed-form led screen, with the help of a flexible display, you can easily create special-shaped LED screens with different shapes.

4. Features of P2.5 SMD LED modules

  • The display effect of the UNIT P2.5 SMD LED module is clearer and more delicate. Better than P4, P5, and P10mm screen display. High resolution, high contrast, high refresh rate, high grayscale.
  • High-bright LEDs and high-quality plastic parts can get a good display effect. There is no afterimage on the screen, and the unique mask can effectively reduce the appearance of water ripples.
  • Using SMD 3 IN 1 technology, the lamp beads have good luminous efficiency. The brightness of outdoor LED modules can meet people’s viewing needs in the sun.
  • It can be arbitrarily spliced according to the horizontal and vertical directions to obtain different sizes of displays.
  • Various sizes and support for customization. Wide range of applications.

5. What can P2.5mm LED Panels do for You?

High-quality P2.5 led modules are used in various display products. The types of displays that p2.5mm LED modules can be used for:

(1) Fine pixel pitch LED display

(2)Commercial LED display

(3)Poster LED display

(4)Soft flexible LED display


The compatibility of P2.5mm led modules with various display screens comes from its excellent performance and high protection level. Smaller spacing brings high-definition picture quality and wonderful visual effects.

At the same time, modules of various sizes can be adapted to cabinets with different sizes. Below is the size table of the UNIT P2.5 led module.

6. P2.5 LED Module Price Comparison

The price of outdoor P2.5mm led modules is higher than that of indoor modules. This is because that outdoor modules require higher protection levels. The requirements for waterproof, moisture-proof, shock-proof, and UV-proof are more stringent.

SMD full-color P2.5 led module is the most cost-effective. Mature production technology creates high-quality products. It can adapt to most installation environments and meet the needs of the vast majority of customers in the market, so P2.5mm SMD LED modules have occupied nearly 80% of the market share.

As emerging LED packaging technologies, GOB and COB have not been fully promoted. Due to the more cost of materials and technology research and development, the price is slightly higher. However, high investment also brings high returns. It is undeniable that GOB p2.5mm led modules have some unique advantages compared to the traditional led modules.


P2.5 soft led modules have a high refresh rate and wide viewing angle. It is suitable for all kinds of creative architectural design schemes, such as hotel halls, bars, science and technology museums, playgrounds, theme restaurants, etc. Want to know more affordable soft flexible LED module prices?

LED Display Module Aging Testing

The aging test is an important guarantee of the reliability of LED modules. It has been used to simulate a long-term working environment to test whether the LED display module will appear abnormal. UNIT’s LED modules will be packaged and shipped after they have passed the strict aging inspection process and are determined to have no quality problems.

LED aging methods include constant current aging and constant voltage aging. Constant current aging is in line with the LED current operating characteristics. Through such aging with a constant current source with adjustable frequency and adjustable current, many hidden LEDs that cannot be detected by conventional aging can be found.

Aging process:

  • Check the modules and boxes. Ensure that the installation is correct, there is no short circuit phenomenon, and the module has no bumps and scratches.
  • Light up aging. Lights up with an online control system. The test time lasted more than 72 hours.
  • Inspection indicators. After the aging test is correct, the quality inspectors conduct parameter index detection.

The test contents of the Led display and module include white screen, red, green, and blue monochrome, grayscale gradient, video effect, and text effect. LED modules that have problems after the aging test should be repaired and replaced in time. Ensure that all parts shipped to customers are functional.
