LED ticker screen for Coca-Cola

A project in which we embedded an LED screen inside a refrigerator door.
The refrigerator has been piloted all over the country. The refrigerator's specifications are the same as those of the other refrigerators, with the difference being the addition of an LED screen – which projects an advertisement for Coca-Cola.
From this refrigerator, with the LED screen, drinking bottles were purchased at 50% more than the refrigerators with the same specifications but without an LED screen.
