If we were talking about multiple screens, would skarpare become plural?

No, comparative adjectives are incredibly easy in Swedish because they never change! Whether you are describing an en-word, an ett-word, or plural nouns, a comparative adjective like skarpare will always keep its exact same ending.

Why do we use på here instead of a Swedish word for of?

In Swedish, the preposition på is commonly used for physical parts attached to a whole object, device, or building. While English speakers often say the screen of the tablet, Swedish naturally uses på because the screen is a physical feature on the device.

How is the word surfplattan built?

It is a compound word that literally translates to the surf plate or the surf slab. It combines att surfa (to surf the web) and en platta (a plate or pad). This is the standard Swedish word for a tablet computer, and the ending -n makes it definite.
