What does the LED display refresh rate mean? The "refresh rate" of the LED transparent screen, also known as "refresh frequency", is in HZ; it refers to the update rate, which is usually greater than 60HZ and cannot be distinguished by the human eye. Below, TY takes everyone to understand the difference between these two common refresh rates.

The difference between LED refresh rate 3840Hz and 1920Hz.

Two common refresh rates for LED displays are 1920HZ regular refresh and 3840HZ high refresh.

1. Refresh frequency is the speed at which the screen refreshes. A low refresh rate will cause image flicker and jitter.

2. Flicker and jitter cause visual fatigue, and long-term viewing will cause eye fatigue.

3. The higher the refresh rate, the less damage to the eyes.

4. At the same time, the high refresh rate can ensure the photo effect of mobile phones or cameras and reduce the phenomenon of water ripples for venues that require photography.

5. There are two kinds of 1920HZ and 3840HZ, there will be some differences in cost, you can choose reasonably according to the budget.

Although to the human eye, the visual refresh frequency of more than 60Hz has been perceived as a continuous picture, but the higher the visual refresh frequency, the more stable the displayed image, and the less likely the eyes will feel fatigue. Nowadays, in high-quality video, in order to obtain more detailed images, such as wonderful playback or close-up photography, high-speed cameras above 1,000 Hz per second are used for shooting. At this time, it is a big challenge for the LED transparent screen to be photographed to present continuous images under high-speed shutter.

The refresh rate of the LED transparent screen is not less than 3840Hz, and the camera captures the picture stable, which can effectively solve the tailing and blur in the rapid movement of the image, enhance the definition and contrast of the image, make the video screen smooth and smooth, and not easy to be fatigued after long-term viewing ; With anti-gamma correction technology and point-by-point brightness correction technology, the dynamic picture display is more real, natural, unified and consistent.

The small-pitch LED display in the conference room and the small-pitch outdoor LED display require human eyes to watch at close range for a long time, so they use 3840Hz.
