The differences between plasma and LED televisions include the maximum viewing angle at which the image retains saturation and rich colors, and the light output that determines the quality of the image in bright environments. Plasma and LED TVs also differ with respect to their power consumption and dynamic contrast.Continue Reading
Most LED TVs as of 2015 use strips of light-emitting diodes across the edge of the screen or a grid of LEDs that illuminate the entire screen to bolster the light output and improve the image quality in rooms with high levels of ambient light. When compared to LED TVs, plasma TVs feature a lower brightness peak, which hurts the image quality during sunny days and leads to flickering and shimmer while the screen is displaying a bright image. However, plasma TVs individually light every cell on the screen, which results in better dynamic contrast and black level by being able to dim specific areas of the screen. LED TVs suffer in that respect because the backlighting leads to uneven illumination and patches of gray areas while displaying dark scenes.
LED TVs, even the 42-inch models, typically use between 40 and 50 watts, although that amount rises if additional features such as Wi-Fi are active. Even though plasma TVs have become more efficient as the technology improved, they still normally require more power when compared to an LED TV with the same screen size.Learn more about Television & Video
