Organic Light Emitting Diodes (OLEDs) are used to create digital displays in many devices. What are the advantages of OLED displays over Liquid Crystal displays?1. OLED displays can be fabricated on flexible plastic substrates.2. Roll-up displays embedded in clothing can be made using OLEDs.3. Transparent displays are possible using OLEDs.Select the correct answer using the code given below:
✓ Correct answer: c) 1, 2 and 3
ExplanationStatement 1 is correct: OLEDs can be manufactured on flexible materials such as polyethylene terephthalate (PET), which allows the creation of foldable and bendable screens.Unlike LCDs, which require rigid glass substrates, OLEDs can use lightweight and flexible plastics, enabling the development of innovative designs like foldable smartphones and rollable displays.Statement 2 is correct: The flexibility and thinness of OLEDs make them suitable for rollable screens that can be integrated into textiles or wearable devices.This innovation enables the creation of electronic clothing or fabrics with embedded displays, providing new possibilities in wearable technology.Statement 3 is correct: OLED technology supports the development of transparent displays because it does not rely on a backlight.OLEDs produce light on their own, making it possible to create see-through screens that overlay digital content on real-world environments.172
