Pixel

A pixel, short for „picture element“, is the basic unit of digital images. It is a tiny dot on a screen that can take on a specific color. Taken together, these dots form what we recognize as a digital image. Pixels therefore play an important role in any form of display and have become indispensable in the fields of video conferencing technology and presentation technology.

 

Pixels: Importance for displays

Numerous pixels together create an image. The color of each individual pixel is determined by a combination of red, green and blue (RGB). The intensity of each color can vary to create a wide range of colors. The number of pixels in an image is called the „resolution“ and determines how detailed the image is. Higher resolutions, which use more pixels, result in sharper and clearer images.

In digital photography and videography, pixels are crucial for image quality. The higher the pixel count of a camera or screen, the better the image quality usually is. Pixels also play an important role in various areas of digital art and design, where they are used to create fine details and complex textures. At its core, a pixel is the building block that shapes the digital visual world and allows images - from photographs to movies to video games - to come to life on our screens

The relevance of pixels in image processing

As pixels are the basic building blocks of every digital image, they are also particularly important for the area of image editing. They make it possible to edit fine details precisely and turn creative visions into reality. By manipulating individual pixels, image editors can correct colors, adjust contrasts and even add or remove elements of an image.

The number and size of the pixels determine the resolution and therefore the quality and sharpness of the image. Modern image editing software uses this pixel-based structure to achieve complex effects such as blurring, shading and texturing, allowing both photography and art to create visually striking works with impressive accuracy and depth.

 

The height of pixel density: What should you look for when buying a display

The height of the pixel density and consequently the resolution of a display are also typically specified in units of pixels, often as width x height. For example, a resolution of 1920x1080 means that the display has 1920 pixels horizontally and 1080 pixels vertically. These numbers determine the total number of pixels and therefore the screen resolution. Higher resolutions such as 4K (3840x2160) have more pixels and therefore offer more detail and sharper images.

When buying a display, you should pay attention to the resolution in relation to the screen size. A larger screen with a lower resolution can produce a less sharp image, as the pixels are larger and therefore more recognizable. The pixel density, measured in pixels per inch (PPI), is also important. A higher PPI value means a higher pixel density, which results in a sharper image.

The type of display technology used (e.g. IPS, TN, OLED) also influences the picture quality, especially in terms of color reproduction and viewing angle. Another factor that should be taken into account is the refresh rate (i.e. how often an image refreshes), which is particularly important for gaming, for example.
