I've found 
if ($display =~ /[^\-a-z0-9\.]/) {
  #err
}

[download]
to be easiere to read most of the time.
Also if you _read_ the code, Yours says: unless $display is all good chars make an error. Where this says: If there are any illegal chars make an error. I find the latter easiere to understand.
