TelaBranca is an advanced display utility and diagnostics platform engineered to deliver pure fullscreen color surfaces, optical monitor evaluations, balanced color temperature lighting, and display calibration with mathematical signal fidelity.
Built from scratch to eliminate outdated 2000s-era screen testing websites that are cluttered with intrusive ads, TelaBranca leverages modern HTML5 Canvas technology, native Screen Wake Lock APIs, and client-side execution to support OLED, IPS, Mini-LED, and Retina displays up to 360Hz.
Our Mission & Core Engineering Principles
We make lab-grade display evaluation accessible to everyone without mandatory downloads, subscriptions, or invasive tracking.
1. Chromatic Accuracy
Using CSS Color Module Level 4 and Canvas APIs to guarantee uncompressed, mathematically exact pixel output across sRGB and DCI-P3 color spaces.
2. Optical Diagnostics
Dedicated routines for dead pixel isolation, subpixel recovery checks, backlight bleed evaluation, and geometric grid alignment.
3. Circadian Lighting
Planckian radiator color temperature simulation (1000K to 40000K) converting screens into virtual ring lights and blue-light-free reading torches.
4. Zero-Data Privacy
100% client-side memory execution. No images, screenshots, or private sensor data are ever recorded or sent to remote servers.
