datorskärms

A datorskärm, also known as a monitor or display, is a visual output device for computers. It presents information, images, and text to the user in a graphical format. Early computer displays were often monochrome, showing text in a single color against a contrasting background. The development of color displays in the late 20th century revolutionized computing, allowing for more complex and engaging visual experiences.

Modern datorskärmar employ various technologies, with liquid crystal displays (LCDs) and light-emitting diodes (LEDs) being the most common. LCDs use a backlight to illuminate pixels, while LEDs can serve as the backlight or directly emit light for each pixel, offering improved contrast and energy efficiency. Organic light-emitting diodes (OLEDs) represent another advanced technology, providing superior color reproduction and deeper blacks.

Key specifications for datorskärmar include resolution, which refers to the number of pixels displayed horizontally and vertically, determining the sharpness and detail of the image. Refresh rate, measured in Hertz (Hz), indicates how many times per second the image on the screen is updated, affecting the smoothness of motion, particularly in video and games. Response time, measured in milliseconds (ms), describes how quickly a pixel can change color, influencing the clarity of fast-moving images and reducing motion blur. Display size, typically measured diagonally in inches, and aspect ratio, the proportional relationship between width and height, are also important factors for user experience.
