P1.55 Indoor Fine Pitch LED Display – 496×496mm Modular Rental LED Screen

For indoor LED display projects, choosing the right pixel pitch is essential for achieving clear images, comfortable viewing and efficient project investment.

The Alisen ARS Series P1.55 Indoor Fine Pitch LED Display is designed for professional exhibition, event, showroom and commercial display applications. It combines a 1.55mm pixel pitch with a 496*496mm modular cabinet, SMD1212 LED technology and a front/rear maintenance structure.

With a cabinet resolution of 320*320 pixels, 416,025 pixels per square meter and a high refresh rate configuration, P1.55 provides a detailed visual presentation for indoor environments.

Whether you are an AV rental company, exhibition contractor, system integrator or LED display distributor, the P1.55 modular LED panel offers a flexible option for building professional indoor LED walls.

P1.55 is designed for indoor applications where image detail and viewing distance are important.

With a pixel density of 416,025 pixels per square meter, this display can reproduce text, graphics, images and video content with high pixel density.

Compared with larger pixel pitch LED screens, P1.55 provides more pixels within the same display area, making it suitable for environments where viewers may stand relatively close to the screen.

Recommended applications include:

• Exhibition booths and trade shows
• Corporate showrooms
• Conference rooms
• Indoor product launches
• Commercial presentation walls
• AV rental LED displays
• Brand experience centers

For projects requiring a balance between fine image detail and practical project configuration, P1.55 is an option worth considering.

The ARS P1.55 configuration uses SMD1212 LED packages.

The LED arrangement is designed for high-density indoor display applications, supporting detailed visual content and smooth playback.

Main display specifications:

• Pixel Pitch: 1.55mm
• LED Package: SMD1212
• Pixel Density: 416,025 pixels/m²
• Cabinet Resolution: 320*320 pixels
• Calibrated Brightness: 880 nits
• Refresh Rate: 7680Hz–15625Hz, depending on configuration
• Grayscale: 16-bit–8-bit, depending on configuration
• Contrast Ratio: 6000:1
• Viewing Angle: 160° horizontal / 160° vertical

The P1.55 configuration is suitable for controlled indoor lighting environments, including exhibitions, showrooms and event venues.

The P1.55 LED display uses a 496*496mm modular cabinet format.

The cabinet is available in 55mm and 62mm depth configurations, offering flexibility for different installation and structural requirements.

Its modular design allows multiple panels to be assembled into larger LED walls.

Key cabinet features:

• Standard cabinet dimensions: 496*496mm
• Cabinet depth: 55mm / 62mm
• Module dimensions: 248*248mm
• Cabinet resolution: 320*320 pixels
• Cabinet weight: approximately 7.5kg without extensions
• Embedded metal structure
• Integrated handle design
• Quick-lock components
• Protective connector covers
• Multiple connection directions

For rental companies and exhibition contractors, the modular cabinet format helps simplify screen configuration and transportation planning.

The P1.55 configuration supports a refresh rate range of 7680Hz–15625Hz, depending on the selected configuration.

A high refresh rate can help reduce visible scanning artifacts when an LED display is captured by professional cameras under suitable operating conditions.

This is useful for:

• Corporate video recording
• Live event broadcasting
• Product launch filming
• Conference presentations
• Indoor stage backgrounds
• Studio and production environments

The P1.55 configuration also supports grayscale specifications of 16-bit–8-bit, depending on the selected setup.

For projects involving professional video recording, the final receiving card, controller, grayscale and refresh rate configuration should be confirmed together.

Maintenance accessibility is an important consideration for professional indoor LED installations.

The ARS Series supports both front and rear maintenance, allowing technicians to access replaceable components from the appropriate side.

This can be useful in installations where rear access is limited or where maintenance needs to be performed efficiently between events.

Maintenance features include:

• Front-serviceable LED modules
• Rear maintenance access
• Replaceable modules
• Power box locking structure
• Integrated cabinet handle
• Self-locking screws
• Protective connector covers
• Modular structural design

The maintenance method can be selected according to the actual installation environment.

The ARS P1.55 LED display supports multiple indoor installation methods.

Suitable for floor-supported LED walls and event backdrops.

Suitable for compatible truss and suspended display structures.

Allows cabinets to be connected into larger display surfaces.

Can be considered for indoor ceiling-mounted display applications with appropriate structural support.

The connection system also supports 5°, 7.5° and 10° concave configurations per panel using the corresponding connection components.

This provides additional design flexibility for selected curved indoor LED wall projects.

The ARS Series offers three pixel pitch options for different indoor applications.

Pixel density is expressed in pixels per square meter.

P1.29: Best suited to projects prioritizing very high pixel density and close viewing.

P1.55: A versatile fine-pitch option for exhibition booths, commercial spaces and professional indoor events.

P1.93: Worth considering for larger indoor screens and projects where viewing distance and overall budget are important.

The ideal pixel pitch depends on screen dimensions, viewing distance, content requirements and project budget.

Technical parameters may vary by configuration. Please request the latest datasheet for confirmation.
