ProductsFlat Panel Display (FPD) Lighting Inspection Fixtures
Aiming for Zero Defects Through Reliable Lighting Inspection
In today’s world of high-resolution screens and sophisticated display technology, quality is non-negotiable. Flat Panel Displays (FPDs)—found in everything from smartphones to vehicle monitors and PC screens—demand uncompromising inspection to ensure pixel-perfect performance.
Seiken’s FPD Lighting Inspection Fixtures offer a reliable solution for detecting illumination defects early in the production process. They are compatible with a wide range of display-equipped products, including smartphones, in-vehicle rearview monitors, and PC displays using LCD (TFT) or OLED technologies.
By making direct contact with the display’s electrodes using ultra-precise probes, our fixtures power the panel and evaluate its lighting patterns with outstanding accuracy. The result: consistent product quality and support for zero-defect manufacturing goals.
The Structure of FPD Inspection Fixtures
Three Core Components―One absolut System. Our modular design supports diverse applications, offering flexibility without compromising reliability:
Panel Set Board
Tailored for a wide range of panel sizes and specs—including configurations with or without polarizing film. We precisely customize each board to match your FPD’s characteristics.
Press Unit
Available in small, medium, and large formats (2″ to 15″), the press unit combines mechanical durability with refined alignment control—enabling stable, repeatable contact and testing performance.
Contact Head
Engineered for precision, our contact heads accommodate fine electrode pitches (0.3mm inline to 0.15mm staggered double-row). Every element is optimized for clean probe alignment, stable contact pressure, and minimal active-area reflection.
