Patent Description:
In the existing glass door of a refrigerator, a display screen can only be attached to flat or curved glass. However, because a border with a glue distance of at least <NUM> needs to be reserved, the display range of the left and right sides of the existing glass door is limited, and large-screen display cannot be achieved, which affects the display effect.
