a defective sub-pixel and can be seen as a bright (white, red, green or blue) dot or a dark dot on a liquid crystal display

A pixel on an LCD monitor that is either always black or always white. Manufacturers refuse to accept monitors back that have dead pixels. Flicking the pixel with your finger removes the dead pixel.
A pixel on an LCD screen that remains white, when it should be displaying a color. Each pixel on an LCD screen is made from one red, one green and one blue subpixel. When these colors are combined, they form the colors that the users see on the screen. A dead pixel occurs when the transistor that displays the light that shines through the subpixels does not work, and results in a permanently white pixel.
A dead pixel is a defective pixel that remains unlit on an LCD screen or a CCD or CMOS sensor in a digital camera. The term "dead pixel" is often applied to other defective pixels, but there are also separate terms. A permanently lit (white) pixel is called a hot pixel, and a pixel that stays on a solid color (red, green, or blue) is known as a stuck pixel.
