What is burn-in and what methods of reducing it does NEC offer?
| Like any screen based on phosphor and all other gas plasma screens, plasma displays may under certain circumstances be susceptible to phosphor burn-in, which is the result of the uneven use of the phosphor in the cell. To prevent this, prolonged display of the same image should be avoided.
To reduce burn-in, NEC offers a reduced brightness long-life mode, pixel shift (where the image rotates around several pixels), all-white mode (whereby the screen displays a white image and no additional signal source for a certain period), screen wiper (whereby a white bar moves across the image) and also inverse mode (where colours are displayed inversely). XGA models also offer a soft-focus setting which softens sharp transitions.
