Description
Summary:In this paper, metal trace corrosion in the process of touch panel reliability evaluation was analyzed. The impact of different layer structure, membrane thickness and trace material on corrosion resistance of products was studied. First, scanning electron microscope (SEM) was used to analysis microstructure of corrosion trace cross section, and uv‐vis spectrophotometer, ion chromatograph was used to analysis corrosion product chemical composition, the cause of trace corrosion was analyzed. Then, the impact of environmental humidity, trace material, OC2 film thickness, secondary black matrix coverage, SiOxNy layer on corrosion resistance of trace was studied. Experimental results indicate that humidity is the necessary condition to corrosion, corrosion does not occur when humidity is zero. The corrosion resistant ability of Aluminum alloy than pure aluminum. Increase the film thickness, enhancement secondary black matrix coverage, add SiOxNy layer can greatly increase the corrosion resistant ability of the product.
