The computer screen or touchscreen or any LCD (liquid crystal display) you use consists of millions of programmed tiny lights and is a composition of billions of small light spots called pixels.

The smooth output screen that you encounter is the result of fresh and functioning pixels that is a combination of primary colors RGB (RED, GREEN, BLUE). The unclear and broken screen effect is due to defective pixels or stocking of pixels on one or more colors since the images and graphics are color combinations of RGB.

Difference Between stuck pixel or a dead pixel

A stuck pixel is the one that can be of any color because it is formed due to mismatch mixing of RGB color combination or inactivity of one of the colors whereas a dead pixel is the one that appears black dark because of the dysfunctionality of all RGB colors at a time.

Now, one may encounter different types of dots like dark dots, light dots, or semi-dark dots (in between) which may be due to semi-pixel defects. Different approaches are used to estimate such problems i.e., using color pixel tests (which you can perform by using the same tool which we are proving), let’s look at each briefly.
