Stuck pixel is a common deffect on LCD screens. The problem with stuck pixels are that they remain in the "block light" position. A stuck pixel thinks that it is powered to "darken" that particular element. It requires less power for a LCD display to let light out (white page - or backlights and a disconnected display panel) than to stop it (black image).
Stuck pixels are similar to (and often falsely labeled as) a dead pixel, whose 3 sub-pixels are permanently off, producing a permanently black pixel. 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 repaired through any of several popular methods.
Unlike dead pixels, stuck pixels can be fixed, and there are several popular methods purported to fix them, such as gently rubbing the screen (in an attempt to reseat 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.) Stuck pixels are not guaranteed to be correctable, and can remain faulty for the life of the monitor.
We don't recommend you to use the "gently rubbing the screen" method. You can actually do more harm to the LCD screen. Please use the software method we provide for removing the stuck pixels. You can download it from here.
How do I check for stuck pixels?
Stuck pixels are easy to find when neighbouring pixels are black. Stuck pixels appear as bright red, green, blue, yellow, teal, purple or white points on a black background.
What is a stuck pixel?
A stuck pixel is a common pixel defect on LCD screens. A stuck pixel is a bright dot of colour on a screen which emits colour when it is not supposed to. A stuck pixel will be most visible against a black background, where it will appear red, green, blue, or any combination of the three including yellow, teal, purple or white. Solid red, green, or blue, are the most common stuck pixels.
Stuck pixels are common on LCD computer monitors, LCD televisions and portable devices.
Each pixel on an LCD screen is composed of three cells, one red, one green, and one blue, which produce the visible color of the pixel by their relative brightness. A stuck pixel results from a manufacturing defect which leaves one or more of these cells turned on. Stuck pixels are not noticeable on a white background as the color white is generated by raising the brightness of each sub-pixel to its maximum level.
