Rasterisaattori

Rasterisaattori is a digital display technology that uses a grid of pixels to create images and text on a screen. The term "raster" refers to the grid-like pattern of pixels, which are the building blocks of the final image.

In a rasterisaattori, the pixels are arranged in a rectangular matrix, with each pixel containing a specific color and intensity value. The images and text are created by combining these pixels in a specific pattern to produce the desired visual effect. The resolution of a rasterisaattori is determined by the number of pixels in the grid, measured in pixels per inch (PPI).

Rasterisaattorit were first used in computer graphics and come to be widely used in digital displays, such as computer monitors, televisions, and mobile devices. They have the advantage of being relatively inexpensive to produce and consume less power compared to other display technologies.

However, rasterisaattorit have some limitations. They can suffer from pixelation, where the image appears to be made up of discrete squares, and can experience screen tearing, a phenomenon where the image appears to stutter or flicker. Additionally, rasterisaattorit can have limited color accuracy and gamut, meaning they may not be able to display the full range of colors that the human eye can perceive.

Despite these limitations, rasterisaattorit remain a widely used technology in many digital displays, and advancements in display technology have improved their capabilities and reduced their drawbacks.
