Do we have any Science Gurus here?

When reading about "Display" style humidors you see a lot about how any amount of light can start oxidation. When I think oxidation, I think corrosion and rust. So what actually happens to the cigar? Does it just dry out and lose it's flavor faster? Does it get fragile and eventually crack/split?

Would really love to put my Liga/Tat collection in a display type humidor but not if it's going to ruin the cigar itself.
