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 such as the Nintendo DS and Playstation Portable (PSP). 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. JScreenFix can fix approximately 65% of stuck pix
