Applying Automated Visual Inspection Throughout LCD Display Production

World leaders in consumer electronics and manufacturing rely on Radiant display test and measurement solutions to improve supply chain performance, reduce production costs and ensure a high-quality end product. Radiant Vision Systems' automated visual inspection systems accommodate multiple screen sizes and technologies, including LCD, OLED, projection and more. Systems can be implemented throughout the display manufacture process to test display quality every step of the way for fully-automated quality control. ProMetric® Imaging Colorimeters and Photometers provide absolute measurements of luminance and chromaticity values using CIE-matched filters and calibration for quality that matches human perception.

See how Radiant's imaging photometers and colorimeters are used at each stage in the production of display devices to detect light, color and surface defects. By identifying defects as early as possible on the line, their systems facilitate lean operations by improving efficiency, lowering production costs and reducing material waste, while ensuring absolute quality of LCD devices from display to final mechanical assembly. Systems identify luminance, color, uniformity, mura (based on “Just Noticeable Difference” (JND)), pixel and line defects, particles and other display characteristics, as well as defects in glass and surfaces or complex mechanical assemblies. From BLU characterization to LCD module evaluation and assembly verification, Radiant offers a complete solution for imaging, analysis and software that increases efficiency for comprehensive LCD display quality control.
