This study explored the effects of rinsing solutions on the surface energy and elemental composition of Corning's EAGLE-XG® display glass, as well as its water adsorption/desorption behaviors and their impact on surface charging/discharging behaviors. The study employed aqueous solutions with different pHs to immerse the glass samples for 1 min and then characterized them immediately after quick drying using various spectroscopic techniques. The results show that the surface-free energy and overall elemental composition of the glass surfaces were insensitive to the exposure to different pH values. However, the O/(Si + Al) ratio of the glass network exposed at the topmost surface was altered, and the water structure and desorption rate also varied among the samples rinsed with different pH solutions. Interestingly, it was found that the DI water treated surface appeared to discharge more slowly than the pH 1 or pH 13 solution treated surfaces, which correlated with the temporal change of water structure. Overall, this study provides important insights into the fundamental questions regarding the impact of the rinsing process on display glass panel surfaces and what characterization techniques are sensitive to the chemistry change in the topmost layer, which will facilitate future research and development efforts.
