Organic Light-Emitting Diodes (OLEDs) are used to create digital displays in many devices. What is/are the advantage 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 statements is correct
▶ Answer & Explanation
Correct answer: C. 1, 2 and 3
OLED technology utilizes organic compounds that emit light when an electric current passes through them, enabling them to be manufactured on thin, flexible, and even transparent substrates. This inherent flexibility and thinness allow for the creation of novel display formats like rollable screens or transparent panels, which are not feasible with traditional Liquid Crystal Displays (LCDs). LCDs require a backlight and are generally rigid, limiting their application in portable and unconventional designs.
