Screen Door Effect on LED screens


Since the introduction of LED screens, some laptop buyers have reported that their screens exhibit an annoying artifact called "screen door effect".The pixel grid is very visible and the screen image looks grainy.
The effect can also be described as like there is a black wiremesh between the color pixels.

The defect has been reported on many different screens, from low- (HD Ready) to high-resolution (Full HD), mainly on matte screens but also on some glossy screens, and nearly on all brands.

Here is an image that simulates the subjective effect on such a screen.
