QUESTION
I'm really new to Vue and can't seem to get how an event is passed from one component to other components. I'm currently using v-blur and I want to blur every component except the one clicked. I figured by passing an event to the other components when the original component is clicked on i could get the effect wanted. Any help is much appreciated!

Very typical solution is to have the so called "Event Bus" - a separate dummy Vue instance, that you use only for events. Here's a full tutorial about Global Event Bus in Vue.
It looks something like this:

and ng-click "change_display($index)"
