Question

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?

1OLED displays can be fabricated on flexible plastic substrates.
2Roll-up displays embedded in clothing can be made using OLEDs.
3Transparent displays are possible using OLEDs.

Select the correct answer using the code given below:

  1. 1.

    OLED displays can be fabricated on flexible plastic substrates

  2. 2.

    Roll-up displays embedded in clothing can be made using OLEDs

  3. 3.

    Transparent displays are possible using OLEDs

Options

a

1 and 3 only

b

2 only

c

1, 2 and 3

Answer
d

None of the above statements is correct

Explanation

All three statements correctly describe advantages of OLEDs over LCDs. Statement 1 is true—OLEDs can be fabricated on flexible plastic substrates, unlike rigid LCD panels, enabling portability. Statement 2 is correct—the flexibility allows for roll-up and foldable displays that can be embedded in textiles and other materials. Statement 3 is accurate—OLEDs can produce transparent displays because each pixel generates its own light, unlike LCDs which require a backlight. These are key technological advantages of OLED technology. > OLEDs = Flexible + Rollable + Transparent. Answer: c.
