The LED screens are equipped with a high contrast ratio and an often elaborate design. Moreover, they prove less demanding in terms of power consumption.
Finally, Plasma screens also have their strong points: smooth image, brightness, large diagonal, optimal contrast ratio … However, they are particularly bulky.

The latter determines the fluidity of the image, which is not negligible because the display should show two images of the same scene to provide a fluid 3D. Specifically, it is advisable to opt for a screen at a rate of at least 200 Hz …
