I must be missing something obvious about Violent Display

[Weltrath]

I keep reading about a cycle of sneak attack and Violent Display, but I must be more dense than Iridium because I can't figure out the 'cycle' to keep qualifying for sneak attack by using Violent Display. I know it's Dazzling Display and Intimidate and Shaken, but I didn't see in Shaken where it gives denial of Dex. Am I just misreading?

Shatter Defenses is the missing piece, I believe.
