PROBE CARD FOR INSPECTING SHORT CIRCUIT BETWEEN SURFACES OF LIQUID CRYSTAL PANEL AND METHOD FOR ROUGHLY SCREENING LIQUID CRYSTAL PANEL BY INTER-SURFACE SHORT CIRCUIT INSPECTION

摘要

PPROBLEM TO BE SOLVED: To efficiently select a COG-LCD panel. PSOLUTION: A short circuit between upper and lower glasses is inspected by using a probe card for inspection which has: an electrode pattern for inspection for connecting all segment electrodes of simple constitution together at a time before an LCD driving IC is mounted on the panel; and an electrode pattern for inspection for connecting common electrodes provided at both ends of the segment electrodes together at a time in order to sort non-defective panels from defective panels, thus performing rough screening as to whether the LCD panel is a non-defective article or a defective article.
