    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:

    A)  1 and 3           

    B)  Only 2

    C)  1, 2 and 3        

    D)         None of these

    Correct Answer: C

    Solution :

    Exp. [c]
    1. A Flexible Organic Light Emitting Diode (FOLED) is a type of Organic Light-Emitting Diode (OLED) incorporating a flexible plastic substrate on which the electroluminescent organic semiconductor is deposited.
    2. OLED displays can be fabricated on flexible plastic substrates leading to the possible fabrication of flexible organic light-emitting diodes for other new applications, such as roll-up displays embedded in fabrics or clothing.
    3. Transparent OLED is a breakthrough transparent display technology that displays dynamic or interactive information on a transparent surface glass.
