P1.25 LED Display Core Parameters Analysis
I. Basic Parameters
Pixel Pitch: 1.25mm (The smaller the pitch, the higher the pixel density, and the finer the image).
Pixel Density: 640,000 dots/㎡ (640,000 pixels per square meter, suitable for close-up HD viewing).
Pixel Configuration: 1R1G1B (surface-mount three-in-one SMD1010 LEDs, red, green, and blue independently illuminated).
Packaging Technology:
SMD surface-mount packaging: Mainstream technology, offering excellent heat dissipation and a wide viewing angle (such as the Nationstar 1010 LEDs).
COB packaging: Used by some high-end models, offering enhanced impact and dust resistance, but at a higher cost.
II. Module and Enclosure Parameters
Module Specifications:
Dimensions: Common sizes include 320mm × 160mm and 200mm × 100mm. Resolution: 256 × 128 dots (320 × 160 mm module) or 160 × 80 dots (200 × 100 mm module).
Case Specifications:
Dimensions: 640 × 480 mm (mainstream), 400 × 300 mm, etc.
Resolution: 512 × 384 dots (640 × 480 mm cabinet) or 284 × 216 dots (400 × 300 mm cabinet).
Material: Die-cast aluminum cabinet, lightweight (6-8 kg), excellent heat dissipation, and high flatness (≤ 0.1 mm).
Maintenance: Front-accessible design for easy installation and maintenance.
III. Optoelectronic Performance Parameters
Brightness:
Typical: ≥ 500 nits (after calibration), with some models reaching 800-1200 nits (adjustable).
Contrast Ratio: 3000:1-6000:1 (High contrast ratio provides clearer images and purer blacks). Refresh Rate: 2880Hz-3840Hz (High refresh rate eliminates screen flicker, suitable for photography and videography).
Grayscale: 12-16bit (65536 grayscale levels, more natural color transitions).
Color Temperature: Adjustable from 3200K to 9300K (adapts to different scene requirements, such as warm or cool lighting).
Viewing Angle: 140° horizontally/vertically (wide viewing angle, no color cast from multiple angles).
Brightness Uniformity: >95% (consistent brightness across all screen areas, no dark areas).
IV. Display and Processing Capabilities
Video Playback: Supports 2K/4K UHD images, no compression or latency.
Frame Rate: ≥60Hz (smooth playback of dynamic images).
Color Uniformity: ≤0.003Cx,Cy (accurate color reproduction, no color cast).
Image Processing:
Supports brightness, contrast, hue, and saturation adjustments.
Equipped with video noise reduction, edge sharpening, and motion compensation.
V. Electrical and Safety Parameters
Power Consumption:
Peak Power Consumption: 800-1200W/㎡ (maximum instantaneous power).
Average Power Consumption: 195-350W/㎡ (in energy-saving mode, low long-term cost).
Power Supply Requirements: AC110-240V (50-60Hz), compatible with global voltage standards.
Protection Rating: IP31-IP45 (dustproof and waterproof, suitable for indoor environments).
Safety Features:
Overtemperature, overload, power failure, image compensation, overcurrent, overvoltage, and lightning protection.
Supports dual power supply and dual system backup for high stability.
VI. Operating Environment and Lifespan
Operating Temperature: -20°C to +50°C (suitable for extreme environments).
Operating Humidity: 10%-90% RH (non-condensing).
Service Life: ≥100,000 hours (approximately 34 years based on 8 hours of use per day). Mean Time Between Failures (MTBF): >50,000 hours (long-term stable operation).
VII. Application Scenarios
High-end indoor displays: Corporate exhibition halls, big data platforms, and command and dispatch centers.
Professional Applications: Broadcasting and television studios, cinemas, and medical imaging displays.
Commercial Applications: Conference rooms, presentation rooms, exhibition halls, and advertising.
With its ultra-fine pixel pitch, high resolution, and high refresh rate, the P1.25 LED display is ideal for indoor applications requiring the highest image quality. Its modular design, front-accessible structure, energy-saving features, and long lifespan further reduce operating costs, making it the preferred solution for high-end large-screen displays.
