What are P2 LED Displays?
P2 LED displays refer to small-pitch LED display devices with a pixel pitch of 2 mm.
They use surface mount (SMD) packaging technology and contain 250,000 pixels (RGB three-in-one lamp beads) per square meter.
Compared with traditional LED displays, P2 can present 4K-level image quality within the optimal viewing distance of 3-10 meters, and is widely used in high-end conference rooms, TV studios, commercial complex digital signage and other scenes.
Milestones of the evolution of China’s P2 LED display technology:
2016: The first commercial P2 screen was mass-produced, breaking through the bottleneck of LED display fineness.
Due to the extremely high resolution of P2 LED displays, the effective viewing distance is greatly reduced, and video and text information can be clearly restored.
2020: COB packaging technology is introduced to achieve IP54 protection level, which can effectively improve the protection ability of P2 LED displays and increase the service life of P2 LED displays.
2023: Dynamic energy-saving technology reduces power consumption by 35%, which can greatly reduce customers’ later use costs. After all, the cost of electricity is a considerable expense in the later use.

Core features of P2 display
Four-dimensional color engine
16-bit grayscale processing: achieve 281 trillion color depth, smooth transition of starry sky scenes, can meet the color requirements of movies and TV stations.
3D-LUT color correction: Delta E <1.5, meet the color accuracy requirements of broadcasting. In this way, when the photographer shoots the picture of the LED display, the picture of the LED display is more realistic.
Ambient light adaptation: The built-in light sensor automatically adjusts the color temperature.
According to the brightness of different environments, it can automatically adjust the color temperature and the brightness of the LED display, so that the audience’s eyes are more comfortable when watching.
Smart display system
Dynamic local dimming:
Partition control reduces power consumption by 30%.
Through the technical design of partition power supply, while reducing energy consumption, the brightness of the P2 LED display is not reduced.
While saving energy, it can increase the service life of the lamp beads of the P2 LED display and the service life of other accessories of the LED display.
Intelligent shadow elimination technology:
Eliminate the afterimage of high-speed motion images. The P2LED display screen manufactured by LEGIDATECH can eliminate the residual effects of the LED display screen when playing high-speed motion videos through the compatibility of intelligent control software and driver IC, and improve the image quality.
Remote cluster management:
The outdoor P2 LED display screen provided by LEGIDATECH can control about 1,000 P2 LED displays in an office cluster through the NOVASTAR cluster management system. It greatly reduces the labor cost for customers.
Military-grade stable performance
Nano coating protection: The dustproof level of the P2 LED display screen reaches IP65.
When the LEGIDATECH LED display factory produces the P2 LED module, it applies a thick layer of waterproof, dustproof and moisture-proof nanomaterials to the surface of the LED PCB.
Wide temperature range operation: The power supply of the P2LED display screen can operate stably in extreme environments of -40℃~+60℃, which improves the stability of the P2 LED display screen.
Earthquake-resistant design: When we produce P2 LED display screens, the first step is to manufacture a sample first piece and pass the MIL-STD-810G military standard test. Only in this way can we mass-produce LED display screens.
P2 LED product matrix and application scenarios
Commercial display solution
Smart conference all-in-one machine:
Due to the high resolution of P2 LED display screens, it can already meet the needs of conference use.
P2 smart conference all-in-one machine has multiple functions:
support Windows/MacOS/Android multi-system screen projection; 20-point touch + electronic whiteboard function; thickness ≤80mm, front maintenance design, the front maintenance design allows maintenance personnel to eliminate P2 LED display faults in a very short time.
Professional audio-visual field
Broadcasting-grade studio wall: Indoor P2 LED display screens use high-pixel density display units with micro-pixel pitch, can be wirelessly spliced, can support 2K, 4K and ultra-high resolution display, and play an important role in news live broadcast rooms, studios and other scenes.
The technical standards that the P2 LED display needs to meet are as follows: 7680Hz refresh rate + 12G-SDI direct connection, support for HDR10+/HLG dual standards.
The refresh rate of the P2 LED display must be able to meet certain requirements so that when the camera shoots the video, there will be no problems such as “black light bands” due to the difference in refresh rates between the two.
P2 LED display for virtual production: Using the P2 small-pitch LED display as the background wall, its wide viewing angle characteristics can prevent the output image quality from being lost due to changes in shooting angles,.
And at the same time, the screen surface is not prone to reflective light spots including moiré. The following technical requirements must be met: 0.02ms low latency, matching the motion capture system; no moiré shooting characteristics.

P2LED display vs P2.5 LED display:
P2 and P2.5 are two commonly used specifications for indoor full-color LEDs. Do you know the differences between P2 and P2.5 LED displays?
What are the advantages of P2 and P2.5?
Because as long as the dot pitch is different.
Then there must be differences in display effects and prices, and these differences will directly affect the user’s choice, especially how to choose a product that is more suitable for them within a controllable budget.
On the surface, the most direct difference between the P2 and P2.5 LED display screens is that the dot pitch is 0.5 mm, that is, the dot pitch is different.
The distance between the two lamp beads of the P2 LED display screen is 2 mm, and the P2.5 is 2.5 mm. The former has a smaller dot pitch.
So we can know that the difference between the P2 and P2.5 LED display screens is mainly caused by the difference in dot pitch.
The dot pitch of P2 is smaller, so the more pixels under the same display area, the higher the resolution, so the clearer the picture is when it is displayed.
In addition, if we want to create a display screen with a fixed resolution, the use of P2 can use fewer modules and a smaller display area to achieve the desired effect.
So this is also the main advantage of P2. After all, the higher the clarity of the LED display screen, the better the viewing experience and the better the texture of the picture.
In addition, although the dot pitch of P2.5 is larger, it also has an advantage over P2 LED display, that is, it is cheap.
Although it is only 0.5mm dot pitch, the unit price of one square meter may be hundreds or even thousands of yuan.
Because we all know that under the same conditions, the smaller the dot pitch, the higher the price, especially for this kind of full-color small pitch products, the price may be doubled or even more for each point difference.
So we can clearly know that the main difference between P2 and P2.5 LED display is the different dot pitch, which leads to the difference in the clarity of the display screen, and the price difference, the smaller the dot pitch, the cheaper it will be. These two points are exactly the advantages of P2 and P2.5.
If we want a higher-definition display, then try to choose P2. If the budget is limited, you can choose P2.5.
Development trend of indoor LED display:
Small pitch LED display:
Small pitch LED display refers to indoor LED display with a dot pitch of P2.5 or below. In 2023, the sales of China’s small-pitch LED display market will be 15.5 billion yuan, a year-on-year decrease of 6.1%.
The shipment area will be 1.084 million square meters, a year-on-year increase of 16.7%. Despite the decline in sales, the increase in shipment area shows that market demand still exists.
In 2024, the market size of small-pitch LED display is expected to reach 17.4 billion yuan, a year-on-year increase of 11.8%1.
Ultra-high-definition, naked-eye 3D, AI+, micro-pitch, COB and other technologies:
High-end technologies such as ultra-high-definition, naked-eye 3D, AI+, micro-pitch, COB and other technical products are accelerating their landing and becoming the new favorite of the market. In particular, the demand for P0.7 indoor screens, P1.5 and above COB screens, and LED crystal particle products with a size of less than 100 microns has increased significantly.
