    $scope.yeardisplay = display;       
    $scope.yeardisp = $scope.displayyears.push($scope.yeardisplay);
    $scope.displayyearss = uniq($scope.yeardisp)

Try checking if the yeardisplay is already in the array before you add it

$scope.displayyears = [];
$scope.Joinyear=function(display){
     $scope.yeardisplay=display;        
     if ($scope.displayyears.indexOf(display) == -1) {
         $scope.displayyears.push(display);
     }
}
