What are pixel defects? Is my display defective?
A certain number of pixel defects are expected on LCD panels and do not constitute a defective display. Each graphic pixel on an LCD screen is made up of red, green, and blue subpixels. Due to the variables inherent to the manufacturing process, some of these subpixels become stuck in either the on or the off state. This pixel defect, also called a stuck pixel, appears as a small red, green, or blue dot for stuck-on pixels, or a small black dot for stuck-off pixels. During the manufacturing testing process, LCD panels that exceed a specified number of stuck pixels are rejected. In order to provide the latest flat panel technology at a reasonable price, LCD manufacturers allow a small number of pixel defects in their quality-control specifications. Although these specifications are improving all the time, with fewer pixel defects allowed with every new generation of displays, a zero-defect policy today would be prohibitively expensive. Even though SGI flat panel displays have some of th
