This system precisely measures and analyzes the luminance uniformity of display modules, supporting pixel-level brightness mapping. Using high-precision acquisition and compensation algorithms, it identifies dark spots, bright spots, and edge roll-off, generating a correction matrix for hardware drivers to achieve full-screen brightness consistency. It outputs heatmaps and statistical reports to aid quality inspection and process improvement. For self-emissive technologies like OLED and Mini-LED, it effectively mitigates the mura effect, enhancing yield and visual experience—an indispensable tool for high-end display production lines.
