Contrast ratios in LCDs and plasma - contrast between black and white: larger the ration the better
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because in LCDs and plasma displays, the contrast ratio refers to the difference in brightness between the darkest black and the brightest white that the screen can produce. A larger contrast ratio means a greater difference between the two extremes, resulting in a more vibrant and visually appealing image. Therefore, a higher contrast ratio is generally considered better as it enhances the overall picture quality and improves the viewing experience.Rate this question:
