pixels
n. countable B1 Intermediate US //ˈpɪksəɫz// UK //pˈɪksəlz// pix·els
n. the tiny dots of color that make up the image on a computer or phone screen. When you have more of these dots, the picture looks clearer.
n. the smallest discrete components of an image on a digital display or sensor. Typically arranged in a two-dimensional grid, their density determines the resolution of the screen.
The image looks blurry because it does not have enough pixels.
Modern smartphone screens pack millions of pixels into a small area to create a perfectly sharp image.
If you enlarge a low-resolution photograph too much, the individual pixels become visible to the naked eye, resulting in a blocky effect known as pixelation.
Usage
Usually used in the plural when discussing screen resolution or image quality.
