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 codes given below:

(a) 1 and 3 only

(b) 2 only

(c) 1, 2 and 3

(d) None of the above statement is correct

Answer: (c)        

Explanation:

• Organic light emitting diode (OLED) displays made with plastic substrates have several appealing features.
• They are extremely thin and lightweight, and can be produced on flexible plastic to take advantage of the substrate’s flexibility.
• Furthermore, OLED displays can be incorporated into roll-up displays integrated into clothing, and transparent displays can also be created.
• Therefore, statements 1, 2, and 3 are correct.
