This set of Video Engineering Multiple Choice Questions & Answers (MCQs) focuses on “OLED TVs”.
1. What is the full form of OLED?
a) Organic Light Emitting Diodes
b) Operating Line Electronic Diodes
c) Organic Liquid Electric Diodes
d) Operating Liquid Emitting Diodes
View Answer
Explanation: OLED stands for Organic Light Emitting Diodes. OLED is a flat light emitting technology, made by keeping a series of organic thin films between two conductors. When electric current is passed, a bright light is radiated. OLEDs can be used to make displays and lighting.
2. OLEDs are made up of carbon and hydrogen.
a) True
b) False
View Answer
Explanation: OLEDs are made from carbon and hydrogen and do not contain any bad metals. They are hence organic in nature. There is no connection to organic food or farming though. They are thinner, do not need backlight and are very efficient. So it’s real green technology.
3. Which of the following televisions delivers the best picture quality?
a) LCD
b) Plasma
c) 3D
d) OLED
View Answer
Explanation: An OLED TV screen uses OLED (Organic Light Emitting Diodes). OLED televisions are brighter, more efficient and thinner which feature better contrasts and refresh rates than either LCD or Plasma. So, OLED TVs deliver the best picture quality ever.
4. Which company is the leader in OLED production?
a) Xiaomi
b) Nokia
c) Samsung Inc. (Incorporated)
d) Apple
View Answer

5. The use of OLEDs is seen in the curved TVs.
a) True
b) False
View Answer
Explanation: OLEDs are solid state devices made of very thin films of organic compounds that generate light on the application of electricity. The great use of OLEDs is seen in the curved TVs. The curved TVs are a result of the flexibility property of OLEDs.
