Modern LED video wall systems have a wide range of advantages, but one of the biggest is how adaptable the screens can be in terms of both size and shape.

One of the biggest recent advances in video wall technology is modular displays, which can allow for video walls of all shapes and sizes and allowed for an Edinburgh branch of Krispy Kreme to copy a tradition dating all the way back to 1937.

Vernon Rudolph, when he opened his own doughnut shop in Winston Salem, North Carolina, after seeing success selling to shops in Nashville with a light and fluffy glazed doughnut recipe, noticed that people would notice the smell of the hot, fresh doughnuts at night and ask to buy some.

Deciding to take advantage of the appeal, he cut a hole in the wall of his rented building and sold doughnuts through it.

The Edinburgh branch took a high-tech spin on this idea with a video hole in the wall, which takes advantage of the doughnut chain’s ‘Hot Now Hours’ timeslots, where customers can have a doughnut fresh out of the oven at certain times.

With the hole in the wall, surrounding which a high-definition video wall displays a mix of useful imagery and mouth-watering pictures, whilst allowing people to be served directly through the hole in the wall display.

Whilst the star of the show is the video wall itself and the CMS that allows for the beautiful imagery to be shown, the system is also connected to point-of-service tablets that allow staff at the store to control the “Hot Now” state of the store as well as menu board and hole in the wall content.
