Need to replace screen on Lenovo IdeaPad Z585?

My laptop screen has some scratches on it and become just scruffy looking in general, and I want to replace it. However I don't know what screen to buy, or how to remove the bezel around the screen to access it.

I googled guides but they seem to refer to a different model laptop, and tell me to remove the screws around the edge of my screen, but my laptop doesn't have screws around the edges (covered or otherwise).

I found a lenovo user manual for this laptop, but it says I should basically completely take the laptop apart, and I don't know if this is a good idea.

I also don't know what laptop screen to buy, as I want one of equal or greater quality to what's currently in it.

Would this screen work?
