Discover the key specs needed to enjoy clear image quality on your display without any motion blur or flickering. 
Learn about 'refresh rate,' which shows how smoothly moving objects are displayed in videos, and 'response time,' which indicates how quickly images appear on the screen.

Check out this infographic for an easy breakdown of these two critical display performance specs!

 

Refresh rate indicates how many frames can be displayed on the screen per second. It is measured in hertz(Hz). A higher refresh rate reduces flickering, resulting in smoother and more fluid motion on the screen. In contrast, a lower refresh rate can cause motion blur, leading to increased eye strain. In fast-paced games or videos, a high refresh rate provides smoother motion for a more natural viewing experience. However, for static images or text-based content where there is little change on the screen, applying a high refresh rate might consume unnecessary power without noticeably improving image quality. This is where variable refresh rate technology comes into play. Variable Refresh Rate(VRR) adjusts the refresh rate according to the content. It uses a high refresh rate for fast-moving content, such as videos at 120Hz, and a lower rate, like 10Hz, for static images. By applying a flexible refresh rate based on the screen's activity, you can enjoy clear image quality while reducing power consumption. To enjoy clean image quality without afterimages on a display, the response time of the display is just as important as the refresh rate. Response time indicates how quickly the display outputs the image on the screen. It is measured in milliseconds(ms) and indicates the time it takes for pixels to change colors. Typically, it is measured by how long it takes to change from Black to White or White to Black, or by timing the transition from 10% to 90% gradation of gray. The shorter the response time is, the clearer an image is on screen due to less residual pixels from the previous image. Unlike standard response time, MPRT(Motion/Moving Picture Response Time) measures the time it takes for motion blur to appear and disappear in video. By displaying a specific pattern on the screen and moving it at a set speed, the resulting blur, or 'trail,' is analyzed. Since OLED displays do not require liquid crystals, they have a fast reaction speed, which means MPRT is lower, providing smoother and clearer video quality.
