P1.25 COB Fine Pixel Pitch LED Display with 3840Hz and 16-Bit Grayscale

High-Density Indoor LED Video Wall for Professional Visual Applications

The AlisenLED P1.25 COB Fine Pixel Pitch LED Display is designed for professional indoor environments that demand high image detail, smooth visual performance and reliable long-term operation.

With a 1.25mm pixel pitch and 640,000 pixels per square meter, the display provides an exceptionally high pixel density for close-viewing applications. The combination of Flip Chip COB technology, 3840Hz refresh rate and 16-bit grayscale delivers detailed images, smooth motion and refined tonal transitions.

The display uses a 600 × 337.5 × 40mm die-cast aluminum cabinet with a compact 3.9kg cabinet weight, providing a lightweight and precise solution for professional fixed LED video wall installations.

1.25mm Pixel Pitch for Close-Range Viewing

With a 1.25mm pixel pitch, the LED display achieves 640,000 dots/m², providing a dense pixel structure for high-resolution indoor visual applications.

This high pixel density makes the P1.25 display suitable for environments where audiences or operators may be positioned relatively close to the screen.

It can clearly present:

• Fine text
• Data dashboards
• Presentations
• HD video
• Detailed graphics
• Monitoring information
• Maps
• Live video feeds
• Digital signage content

For conference rooms, command centers and other professional spaces, P1.25 provides a strong balance between image detail and viewing distance.

Flip Chip COB Technology

The display uses Flip Chip COB LED technology rather than conventional SMD packaging.

COB technology integrates the LED chips directly onto the PCB and provides an encapsulated display surface. This creates a more integrated LED structure while improving protection of the LED components.

Key COB Advantages

• Protected LED chip structure
• Enhanced resistance to physical contact
• Refined and uniform display surface
• Efficient thermal management
• Suitable for fine pixel pitch applications
• Designed for demanding professional environments

For premium indoor LED projects, COB technology provides both a high-density display structure and a more protected LED surface.

30,000:1 High Contrast Ratio

The P1.25 COB model provides a 30,000:1 contrast ratio, helping create a stronger distinction between dark and bright areas of the image.

This is particularly valuable for:

• High-definition video
• Dark scenes
• Corporate presentations
• Digital artwork
• Multimedia content
• Professional visual environments

A high contrast ratio helps images appear deeper and more visually defined.

600 cd/m² Brightness with ≥98% Uniformity

The display provides 600 cd/m² brightness with ≥98% brightness uniformity, helping maintain consistent visual performance across the LED screen.

High brightness uniformity is particularly important when multiple cabinets are assembled into a large video wall.

Consistent brightness helps reduce visible differences between display areas and creates a more unified viewing experience.

3840Hz Refresh Rate for Camera-Friendly Performance

The 3840Hz refresh rate is designed to provide smooth image reproduction for dynamic visual content.

It helps reduce visible flicker and supports professional environments where LED screens may be captured by cameras.

This makes the display suitable for:

• Broadcast studios
• Video production
• Corporate video conferencing
• Live streaming
• Photography
• Recording environments

The high refresh rate provides stable visual performance for both direct viewing and camera-based applications.

16-Bit Grayscale for Smooth Image Transitions

The P1.25 COB LED Display supports 16-bit grayscale processing, providing smooth transitions between different brightness levels.

This helps improve the reproduction of:

• Dark scenes
• Shadows
• Gradients
• Skin tones
• Complex video content
• Low-brightness details

For professional applications where image quality matters, 16-bit grayscale helps create a smoother and more natural visual experience.

Compact 40mm Cabinet Design

The P1.25 COB LED display uses a 600 × 337.5 × 40mm cabinet made from die-cast aluminum.

With a cabinet weight of only 3.9kg, the compact structure makes the display easier to integrate into professional indoor installations.

Cabinet Highlights

• 600 × 337.5mm cabinet size
• Only 40mm cabinet depth
• Die-cast aluminum construction
• 3.9kg cabinet weight
• 480 × 270 cabinet resolution
• 300 × 168.75mm LED module

The compact cabinet structure provides flexibility when designing high-resolution LED video walls.

Front Service for Easier Maintenance

The P1.25 COB LED Display is designed with front serviceability, allowing maintenance access from the front of the display.

This is especially useful for fixed installations where there is limited space behind the LED wall.

Front Maintenance Benefits

• Convenient LED module access
• Reduced rear clearance requirements
• Easier wall-mounted installation
• Faster maintenance operations
• More flexible installation planning
• Reduced disruption during servicing

The display is specified with IP40 protection on the front and IP20 on the rear for indoor applications.

Efficient Power Performance

The P1.25 COB model has a maximum power consumption of approximately 285W/m² and an average power consumption of approximately 115W/m².

This makes it suitable for professional indoor projects where display performance and operational efficiency both need to be considered.

The system supports 100–240V AC input and 50/60Hz operation.

Designed for Long-Term Professional Operation

The display is specified with a 100,000-hour lifespan, making it suitable for professional indoor installations requiring long-term operation.

It is designed for an indoor operating environment of:

• Operating Temperature: -10°C to 40°C
• Operating Humidity: 10%–90% RH
• Ingress Protection: IP40 front / IP20 rear
• Application: Indoor
