What is the difference between high refresh rate and regular refresh rate LED display screens?

The refresh rate of LED display screen, also known as "visual refresh rate" or "refresh rate", refers to the number of times the display device updates the screen content per second, measured in Hz (Hertz). Generally speaking, the higher the refresh rate, the easier it is to eliminate flicker, the smoother the image, and the smoother the picture.

General brush vs high brush

The refresh rate of a standard LED display screen is 1920Hz;

The refresh rate of the high refresh rate LED display screen is above 3840Hz;

Generally speaking, a refresh rate of 1920Hz or higher is sufficient to meet daily playback needs.

The higher the refresh rate, the less flickering the image on the LED display screen, the higher the stability, and the better the protection of vision. The lower the refresh rate, the more noticeable the image lag and delay. Under the same viewing time, a screen with a low refresh rate is prone to eye fatigue.

The relationship between refresh rate and frame rate

Both can be expressed as the number of images in one second. But the refresh rate is the ability of the screen display, measured in Hz; And frame rate is an attribute of the content itself, measured in fps. They are two completely independent individuals, but have a close relationship in daily use.

How to choose: Is a higher refresh rate better?

Choosing a refresh rate that is suitable for the application scenario is the most important.

For most application scenarios, regular brush can meet basic visual needs. But if you need to watch the screen for a long time, pursue the ultimate visual experience, or in scenes that require high-speed photography and recording, high refresh rate LED displays are the best choice due to their ability to almost eliminate water ripples and flicker.

1. A high refresh rate is less likely to cause ghosting, the image is stable, and the smoothness is high;

2. Taking photos with a mobile phone or camera reduces the occurrence of water ripples, resulting in clear and high-quality images;

3. Long term viewing effectively reduces visual fatigue;

summarize

In summary, there are significant differences between high refresh rate and regular refresh rate LED displays in terms of image fluency, visual comfort, shooting effect, and application scenarios. When choosing, one should weigh the specific application scenarios and needs to obtain the best visual experience. With the continuous advancement of technology, the refresh rate of LED displays will further increase in the future, bringing viewers a more stunning visual feast.
