A browser-based toolkit for OLED display testing and diagnostics, built with ASP.NET Core 10 MVC.
Fills the screen with a uniform grey level controlled by a slider (0–255). Useful for testing uniformity and identifying early burn-in at various brightness levels.
Fills the screen with a solid colour — white, red, green, blue, or black — to make stuck or dead pixels immediately visible against a uniform background.
An animated black hole simulation running entirely on an HTML5 canvas. Particle systems render the accretion disk, photon ring, infalling matter, and relativistic jets against a field of twinkling stars. All pixels outside the simulation are pure black, keeping OLED panels dark.
