This set of Video Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Performance Comparison of Plasma and LCD TV”.
1. Both LCD TV and Plasma TV provides the smart TV feature.
a) True
b) False
View Answer
Explanation: LCD and Plasma are two technologies that produce images via immensely different processes; each comes with its own factors of favorability. LCD and plasma TV both consist of flat panel designs that allowed them to be table or wall mounted. Even the smart TV features can also be provided in both platforms as that is independent of the technology used to display images on the screen.
2. Which of the following is the disadvantage of Plasma TV?
a) Poor response time
b) Poor color depth
c) Poor contrast ratio
d) Susceptible to burn-in
View Answer
Explanation: The main disadvantage of plasma TV is that it is more susceptible to burn-in. Plasma TVs suffer from occasional image retention if they display the same image for a very long period of time. This has been improved a lot in the last few years, and permanent burn-ins is no longer an issue.
3. Generally the range of LCD TVs varies from 19 inches to 70 inches.
a) True
b) False
View Answer
Explanation: The above statement is false. LCD TVs can be made in small screen size. LCD TVs are usually lighter compared to the same screen sized plasma TVs. LCD TVs are available in many screen sizes ranging from as small as 19 inches to as large as 90 inches.
4. What is the full form of CCFL?
a) Color Cathode Figure Lamp
b) Crystal Cathode Fluorescent LED
c) Cold Cathode Fluorescent Lamp
d) Crystal Cathode Fluorescent LCD
View Answer
Explanation: CCFL stands for Cold Cathode Fluorescent Lamp. The old CCFL LCD TVs are now replaced by LED backlit LCD TV which is simply known as LED TVs. In recent few years, both plasma and CCFL LCDs are virtually extinct, and LED is the remaining reasonable choice.
5. Which TVs are more bulky compared to LCDs?
a) Plasma
b) 3D
c) LED
d) OLED
View Answer
Explanation: Plasmas are more bulky compared to LCDs. The plasmas are about 3 inches deep whereas the LCDs have a depth of around 2 inch. Modern LCDs (LEDs) are even slimmer than both. The lifespan of LCD screen is also more compared to the plasma screens.
