Select the correct answer using the code given below:
- 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
Options
1 and 3 only
2 only
1, 2 and 3
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.
