näyttökerroin

Näyttökerroin, also known as the display factor or screen factor, is a term used in the field of display technology and visual perception. It refers to the perceived sharpness or clarity of an image displayed on a screen. This factor is influenced by several elements, including the screen's resolution, pixel density, and the quality of the display panel itself.

Higher resolution screens, with more pixels packed into the same physical area (higher pixel density), generally result in a higher näyttökerroin, leading to a more detailed and less pixelated image. The technology used in the display, such as LED, OLED, or IPS, also plays a crucial role in how accurately colors are reproduced and how effectively the screen can display fine details.

Furthermore, the viewing distance and the user's visual acuity can affect the perceived näyttökerroin. What might appear sharp at a close distance might seem less so from further away. Manufacturers often use terms like "Retina display" to indicate a very high pixel density, implying a näyttökerroin so high that individual pixels are indistinguishable to the human eye at normal viewing distances. While not a precisely defined scientific metric, näyttökerroin is a useful concept for understanding and comparing the visual quality of different display devices.
