There are many digital displays on the market that cater to digital art collectors. But only some of these frames are optimized for block chain-based art (aka, NFTs).

Most of the frames are in square shape. Let's talk about this type of display, Square Touch Screen. A square touch screen refers to a touch screen with a square shape, which has both the characteristics of a touch screen and unique features related to its shape. The following is an introduction of its advantages with regards to its shape:
