I have copied my bookmark file relating to this problem. I collected this information earlier this year, when I was hired by two companies with this problem. The displays used by these companies developed bond problems after 6 months to 1 year in the field. One application was outdoors, and the other was inside. The displays were otherwise identical. My conclusion, which was borne out by a consultant hired by the display manufacturer, was that there was a manufacturing process problem. I hope this information helps. Please feel free to contact me if you feel it would be helpful.
