The tempdata feature for sessions only affects how long the data is allowed to be stored. The removal of the data, after 5 seconds in your case, won't cause anything else to change on the page.

As far as I can tell you don't need tempdata at all. Try this to see if you get the behavior you want.

public function dispdata()
{
    if (!$this->session->userdata('ci_session')) 
    {
        redirect('Form/login');
    }

    $result['data']=$this->Form_model->displayrecords();
    $this->load->view('display_records',$result);
    // sleep for 5 seconds
    sleep(5);
    redirect('Form/login');
}

Why did I remove the else from your code? Because redirect does not return - it ends script execution. So, when the if evaluates to true and the redirect executes this script is done.
