A dot is only a singular quantum while a pixel is actually made up of dots consisting of a red, green, and blue components. By controlling the various combinations and positioning a color picture is generated on the screen or on paper.
dot pitch
it is a dot of light
The dot pitch for a display unit is the distance between individual dots - which may be circular or in the form of an elongated circle (like a running track). Most display units, nowadays, are based on dots of three colours: red, green and blue. A pixel is unit formed by each set of three colours, and a pixel pitch is a measure based on the size of the pixel and the distance between dots of the same colour in adjacent pixels.
False. A dot on the screen that contains a color is called a "pixel."
A pica is a unit of type size, a pixel is a unit of illumination.
A dead pixel is a pixel that stays completely black or unlit because it no longer receives power—it's permanently off. A hot pixel, on the other hand, is always bright, usually showing a fixed color (red, green, or blue), because it’s stuck “on.” Key difference: dead pixels are unlit, hot pixels are permanently lit. Dead pixels usually indicate hardware failure, while hot pixels can sometimes appear temporarily due to heat or pressure and may disappear after a while. Both affect image quality but in opposite ways.

A pixel is one colored dot. in blk & wht one dot will do, but in color you need three.
