Organic Light Emitting Diodes (OLEDs) are used to create digital display 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 (2017)

a) 1 and 3 only

b) 2 only

c) 1 , 2 and 3

d)None of the above

Answer: C
A major advantage of OLED over LCD is that it is lightweight and has flexible plastic substrates.

• OLED displays can be fabricated on flexible plastic substrates, leading to the possible fabrication of flexible organic light-emitting diodes for other new applications, such as roll-up displays embedded in fabrics or clothing.
• If a substrate like polyethylene terephthalate (PET) can be used, the displays may be produced inexpensively.
• Furthermore, plastic substrates are shatter-resistant, unlike the glass displays used in LCD devices.
