képernyfrissítés

Képernyőfrissítés, often translated as screen refresh, refers to the process by which a display refreshes its image. This process is fundamental to how visual information is presented on electronic screens, from computer monitors and televisions to smartphones and tablets. The refresh rate, measured in Hertz (Hz), indicates how many times the screen redraws the entire image in one second. A higher refresh rate generally results in smoother motion and a more fluid visual experience, which is particularly noticeable in fast-paced content like video games or sports.

Different types of displays have varying capabilities regarding screen refresh. For instance, older CRT (Cathode Ray Tube) monitors used a scanning beam to refresh the image, while modern LCD (Liquid Crystal Display) and OLED (Organic Light-Emitting Diode) screens achieve this through electronic control of pixels. The refresh rate can often be adjusted in display settings, allowing users to select a rate that balances performance with potential power consumption. In some cases, dynamic refresh rate technologies adjust the refresh rate automatically based on the content being displayed, optimizing for both visual quality and energy efficiency.
