Black dots appear on my laptop screen and are spreading? how can I get rid of them

If you are talking about dots that look like either of these links then you have a bad LCD and will need to replace it. Can you upload a picture of what it looks like as well as the model of the laptop? https://i.ytimg.com/vi/Gze89ERGvYo/hqdefhttp://i.imgur.com/ed4EOXP.jpg
