How do I apply a date format to a bound display field?

I am using a displayfield to show a date. The field is bound to the view model. When it displays, it uses the verbose default date format. How can I apply a format to the bound value?

Code:

{                                    xtype:'displayfield',
                                    fieldLabel:'Submitted',
                                    bind:'{theRequest.submitted}',
         
                                    cls:'white-text',
                                    labelWidth:80
                                }

I get the right format if I use a datefield, but I don't want the look and feel of that widget.
