Small-pixel TFT flaw detection and measurement using voltage imaging technique

The paper proposed the characteristics of flaw measurement in small-pixel design mobile displays based on TFT array panel with respect to electrical-optic characterization. For advanced small-pixel and high-resolution mobile display applications, the display pixels on array process are smaller, detecting small-pixel defect played an important role than previously seen in non-small-pixel TFT array panels for managing process yield. The study resulted in small-pixel size TFT array show the flaw detection performance and preference approaches using the voltage imaging technique. It provides an initial insight into the high-resolution of small-pixel size designs for advanced mobile displays application.
