Stuck Versus Dead Pixels
Stuck pixels are often incorrectly referred to as "dead pixels", which have a similar appearance. In a dead pixel, all three sub-pixels are permanently off, producing a pixel which is permanently white for TN panels and black for other types of panels. Dead pixels can result from similar manufacturing anomalies as stuck pixels, but may also occur from a non-functioning transistor resulting in complete lack of power to the pixel. Dead pixels are much less likely to correct themselves over time or be repaired through any of several popular methods.
Stuck pixels, unlike dead pixels, have been reported by LCD screen owners to disappear, and there are several popular methods purported to fix them, such as gently rubbing the screen (in an attempt to reset the pixel), cycling the color value of the stuck pixel rapidly (in other words, flashing bright colors on the screen), or simply tolerating the stuck pixel until it disappears (which can take anywhere from a day to years). While these methods can work on some stuck pixels others cannot be fixed by the above methods. Also, some stuck pixels will reappear after being fixed if the screen is left off for several hours.

Famous quotes containing the words stuck and/or dead:
“I wanted him to fly, burst like a missile from your throat,
burst from the spidery-mother-web,
burst from Woman herself
where too many had laid out lights
that stuck to you and left a burn
that smarted into your middle age.”
—Anne Sexton (1928–1974)
“He said the dead had souls, but when I asked him
How could that be—I thought the dead were souls,
He broke my trance. Don’t that make you suspicious
That there’s something the dead are keeping back?”
—Robert Frost (1874–1963)
