Create pixel-accurate PNG test patterns for OEM stock displays and resized LCD/OLED panels.


Create pixel-accurate PNG test patterns for OEM stock displays and resized LCD/OLED panels.

For stock displays, patterns are generated at the full original panel resolution.

For resized or cut displays, the exported image keeps the original panel resolution and places the active test pattern only inside the resized area, with the unused area filled black.

Use the tool to generate color bars, grayscale ramps, checkerboards, pixel-scale patterns, BL uniformity targets, alignment screens, burn-in patterns, and validation images for engineering, production, and incoming inspection.

Pixel Perfect™ Display Test Pattern Generator

Create pixel-accurate PNG test patterns for stock and resized LCD/OLED displays. For stock displays, the test image matches the panel resolution exactly. For resized displays, the image keeps the original panel resolution, places the test pattern only inside the resized active area, and fills everything outside that area with black.
