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.

1. 1 and 3 only
2. 2 only
3. 1, 2 and 3
4. None of the above statements is correct

Explanation

All are correct

• Organic Light Emitting Diodes (OLEDs) are a type of display technology that uses organic compounds that emit light when an electric current passes through them. Unlike traditional Liquid Crystal Displays (LCDs), which require a backlight to illuminate the screen, each pixel in an OLED display produces its own light.
• OLEDs can be fabricated on flexible plastic substrates, allowing for lightweight, bendable displays. Due to their flexibility and thin form factor, OLEDs enable rollable displays and can be embedded in wearable items. OLED technology allows for transparent displays, as they do not require backlighting like LCDs, enabling the creation of see-through screens.
