What is Refresh Rate?
Before diving deep into the details, let’s start by understanding what exactly refresh rate refers to. In the world of TVs and monitors, refresh rate is a term used to describe how many times per second the display updates its image. It is essentially the rate at which the TV refreshes the pixels on the screen to display a new image.
Refresh rate is measured in Hertz (Hz), which represents the number of times the image is refreshed in one second. For example, a TV with a refresh rate of 60Hz displays a new image 60 times per second. Similarly, a TV with a refresh rate of 120Hz refreshes the image 120 times in a second.
The refresh rate is closely tied to the smoothness and fluidity of motion on the screen. A higher refresh rate results in smoother, more lifelike motion, while a lower refresh rate may exhibit noticeable motion blur or juddering during fast-paced scenes. The human eye perceives motion up to a certain limit, so a higher refresh rate can provide a more realistic and enjoyable viewing experience.
It’s important to note that refresh rate is different from frame rate. While refresh rate represents how many times the image on the screen is updated, frame rate refers to the number of individual frames displayed per second in the source content. The two are interconnected, as the refresh rate needs to be able to keep up with the frame rate to provide a seamless viewing experience.
Now that we have a basic understanding of what refresh rate is, in the next sections, we will explore the significance of refresh rate and how it affects picture quality, particularly when it comes to QLED TVs.
Understanding Hertz (Hz)
To better understand refresh rates, it’s important to familiarize ourselves with the concept of Hertz (Hz). Named after the German physicist Heinrich Hertz, Hertz is a unit of frequency that measures the number of cycles per second.
In the context of TVs and monitors, the refresh rate is measured in Hertz. For instance, a TV with a refresh rate of 60Hz updates the image 60 times per second. This means that every second, the screen refreshes 60 times to display a new image.
Higher refresh rates, such as 120Hz or 240Hz, indicate that the screen refreshes at an even faster pace. A TV with a refresh rate of 120Hz updates the image 120 times per second, while a TV with a refresh rate of 240Hz refreshes the image 240 times per second.
By increasing the refresh rate, the TV can display smoother motion on the screen. This is particularly noticeable during fast-paced action scenes or sports broadcasts, where the higher refresh rate can reduce motion blur and provide a more realistic viewing experience.
It’s important to note that not all content benefits from higher refresh rates. Many movies, TV shows, and video games are typically produced and displayed at 24 or 30 frames per second (fps). Since these frame rates are lower than the refresh rates of modern TVs, the TV has to employ various techniques, such as motion interpolation, to fill in the gaps between frames and create smoother motion.
Overall, understanding Hertz and its relationship to refresh rates is key to comprehending the capabilities and performance of QLED TVs. In the next section, we will examine the importance of refresh rate and its impact on picture quality.
