This patent, submitted by Samsung, outlines a design concept for their smart-fridge line. The patent describes the app based display on the front of the fridge, and how it can be used alongside cameras to display the inventory of the fridge. The app also keeps track of how long items have been in the fridge, and displays where they are and when they will expire. The patent also describes other apps, such as a to-do list, a memo page, and a recipe book.
