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:
“A man who publishes his letters becomes a nudist—nothing shields him from the world’s gaze except his bare skin. A writer, writing away, can always fix himself up to make himself more presentable, but a man who has written a letter is stuck with it for all time.”
—E.B. (Elwyn Brooks)
“I dreamed night after night that everyone in the world was dead excepting myself, and that upon me rested the responsibility of making a wagon wheel.”
—Jane Addams (1860–1935)
