Explanation

An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.

Statement 1 is correct: One of the key advantages of OLED technology is that the organic light-emitting materials can be deposited on flexible plastic or metal foil substrates, enabling the creation of flexible and foldable displays.

Statement 2 is correct: The flexibility of OLED displays allows for the creation of roll-up or rollable displays, which can be integrated into clothing and other flexible surfaces.

Statement 3 is correct: OLED display technology can be used to create transparent displays, where the light-emitting pixels can be made semi-transparent, allowing the display to be integrated into various surfaces and objects.

Therefore, all three statements are correct.
