Q24.
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:
Answer
C
Explanation
All three statements are correct with regard to OLED. Flexible OLEDs (FOLEDs) fabricated on flexible plastic substrates can be bent or rolled while operating. OLEDs can be printed onto almost any substrate with inkjet printer technology, making roll-up displays embedded in clothes possible. LCD technology engages a backlight whereas OLED has no backlighting function, hence it can be used for transparent displays.
