A stuck sub-pixel or stuck pixel is a pixel that is always "on". [2] This is usually caused by a transistor that is getting power all the time (VA/IPS) or not getting any power (TN) and is therefore continuously allowing light at that point to pass through to the RGB layer. Any given pixel will stay red, blue, or green and will not change when ...
An image with salt-and-pepper noise. Salt-and-pepper noise, also known as impulse noise, is a form of noise sometimes seen on digital images.For black-and-white or grayscale images, is presents as sparsely occurring white and black pixels, giving the appearance of an image sprinkled with salt and pepper.
In the case of images bright enough to be in the shot noise limited regime, when the image is scaled to the same size on screen, or printed at the same size, the pixel count makes little difference to perceptible noise levels – the noise depends primarily on the total light over the whole sensor area, not how this area is divided into pixels ...

Noise, static or snow screen captured from a blank VHS tape. Noise, commonly known as static, white noise, static noise, or snow, in analog video, CRTs and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices.

From the left: horizontal sync pulse, back porch with color burst, signal itself, front porch, sync pulse, back porch with color burst, video portion of the next scan line.
Retina display is a branded series of LCDs and OLED displays by Apple Inc. that have a higher pixel density than their traditional displays. [1] Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.
A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides illumination from the back or side of a display panel. LCDs do not produce light by themselves, so they need illumination ( ambient light or a special light source) to produce a visible image.
