Seiken FPD Lighting Inspection Fixtures Precision Solutions for LCD and OLED Display Testing In the era of high-resolution displays and advanced visual technology, maintaining consistent screen quality is mission-critical. Whether in smartphones, automotive displays, or PC monitors, every pixel counts—and defective illumination or uneven lighting can compromise performance. Seiken’s FPD Lighting Inspection Fixtures provide a high-precision testing solution for LCD (TFT) and OLED panel inspection, enabling manufacturers to detect lighting and display defects early in production. Designed for fine-pitch contact and stable power delivery, these fixtures help ensure pixel-perfect illumination and support zero-defect manufacturing standards in display production lines. Precision Engineering for Reliable Display Testing Our inspection fixtures are designed for direct contact with display electrodes using ultra-accurate probe technology. This ensures stable electrical connection and enables precise evaluation of display lighting patterns, brightness uniformity, and color accuracy. The result is reliable detection of pixel and backlight defects—essential for achieving consistent quality across high-volume production. Modular Structure — Three Core Components 1.
