LED Matrix Spec Calculator

LEYARD PK LIMITED

About this app

LED Matrix Spec Calculator is an offline engineering and planning utility designed for LED display technicians, field engineers, system integrators, and staging professionals. Calculate critical LED video wall specifications on-site quickly and accurately without an internet connection.

Core Features:

* Aspect Ratio & Dimension Calculator: Enter physical screen width and height in meters to instantly calculate the screen's diagonal size in inches and determine the aspect ratio (such as 16:9, 4:3, 21:9, or 16:10). Features a visual aspect ratio representation of the screen layout.
* Pixel Resolution Calculator: Input the horizontal and vertical cabinet counts alongside specific cabinet pixel grids (e.g., 128x128, 192x192, 256x256, etc.) to calculate total screen resolution, megapixel count, and get recommended Novastar controller models based on pixel budget limits.
* Preset Cabinet Database: Select from predefined industry-standard cabinet specifications (like Indoor P1.9, P2.5, Outdoor P3.9, P4.8, P10) to automatically load pixel pitch, dimensions, average/max power, and weights, or enter custom cabinet parameters.
* Power Load Estimator: Estimate maximum and average electrical power requirements in kilowatts (kW). Calculates estimated active current draw in Amperes for single-phase 110V, single-phase 220V, and balanced three-phase 380V power distribution systems.
* Structure Weight Estimator: Calculate total cabinet dead load weight and structural frame support weights in both kilograms (kg) and pounds (lbs) by defining the weight per cabinet and adding a custom structure safety factor margin.
* Viewing Distance Estimator: Estimate recommended minimum visual acuity distance, comfortable optimal viewing distance, and pixelation visual limit boundaries based on the entered pixel pitch (mm).
* Saved Specifications: Save calculated display configurations locally on your device with custom reference labels. Access, review, or delete saved layouts at any time offline.

Offline Integrity & Privacy:
* 100% Offline: No internet permission or data connection is required to perform calculations.
* Safe & Secure: Zero tracking, no user registration, and no device permissions requested. All data is saved strictly inside the application's local storage sandbox.
