What are pixels on the thumb?

The term pixels on the thumb (PPI), which is also sometimes referred to as pixel density, is used to describe the resolution of digital image. Pixel is the smallest unit that is used to create a digital image and usually exists as the only color dot. For this reason, the image resolution is sometimes referred to as dots on the thumb (DPI) instead of pixels on the thumb or ppi. The number of pixels that exist in a square inch from a digital image define PPI or DPI. If the image expands or reduces the size, the number of pixels per inch changes as the image resolution changes.

When creating or selecting an image for online or printing, the pixels on the thumb is important. A picture that has a low number of pixels per thumb will look fuzzy on the computer screen and when printing. This is of course if the image is not significantly reduced. A picture with a high number of pixels on the thumb, on the other hand, will look more fresh on the computer screen or printing.

Generally, the digital image of good quality 300 pixels per inch or more will have. There are cases where the number of pixels per thumb is much higher. Images that are created for websites that allow users to zoom in pictures in the images are often created in a very high resolution. For example, the website selling fine jewelry could create images with a sufficiently high resolution that allow users to close the details of the image.

The number of pixels per thumb affects the quality of images shown on TV screens and the quality of the images shown on the computer screens. TVs that are able to display high -definition shows and events are able to display more pixels per thumb than TVs that do not have this type of capacity. PPI also affects the display on manual devices such as mobile phones and personal digital assistants. The same applies to mobile devices that are up to a considerable mIirus uses for recreational purposes, such as they are playing music, games and television shows and movies.
