Refresh rate意思

"Refresh rate" is a term primarily used in the context of displays, such as computer monitors, televisions, and smartphones. It refers to the number of times per second that the display hardware updates the image on the screen. The refresh rate is typically measured in hertz (Hz).

A higher refresh rate means that the display updates more frequently, which can result in smoother motion and a more fluid visual experience, especially when it comes to fast-moving content like video games or sports. For example, a refresh rate of 60Hz means that the display updates 60 times per second, while a refresh rate of 120Hz means it updates 120 times per second.

Higher refresh rates are often associated with more expensive displays, as they require more advanced hardware and can consume more power. However, they are becoming more common in modern displays, especially in the realm of gaming, where every millisecond counts.

In the context of web browsing or general computer use, a higher refresh rate can also make scrolling and animations appear smoother, although the difference may be less noticeable than in gaming or video playback.

It's important to note that the refresh rate of a display is separate from the frame rate of the content being displayed. The frame rate is the number of individual frames that are shown per second, and it is determined by the source of the content, such as a video file or a graphics card. A display with a higher refresh rate can potentially display more frames from a high-frame-rate source, but it will not improve the appearance of content with a low frame rate.
