What does the refresh rate of LED transparent screen mean? The "refresh rate" of the LED transparent screen, also known as the "refresh rate", is in HZ; it refers to the update rate, which is usually indistinguishable by the human eye when it is greater than 60HZ. Below, Lianman Optoelectronics takes you to understand the difference between these two common refresh rates.

LED refresh rate difference between 3840 and 1920

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

1. The refresh rate is the speed at which the screen is refreshed. The low refresh rate will cause the image to flicker and shake.

2. Flickering 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, high refresh rate can ensure the photo effect of mobile phone or camera and reduce the phenomenon of water ripples for venues with photo requirements.

5. There will be some differences in cost between 1920HZ and 3840HZ, which can be reasonably selected according to the budget.

Although for the human eye, the visual refresh rate of more than 60Hz has been perceived as a continuous picture, but the higher the visual refresh rate, the more stable the displayed image, and the less likely the eyes will feel fatigued. Today, in high-quality video, high-speed cameras over 1,000 Hz per second are already being shot in order to obtain finer images, such as wonderful playback or close-up photography. At this time, it is a big challenge to present a continuous picture at a high shutter speed for the photographed LED transparent screen.

Lianman HY ultra-light and high-transparency LED transparent screen has a refresh rate of not less than 3840Hz, and the camera captures the picture is stable, which can effectively solve the smearing and blurring in the process of rapid image movement, enhance the clarity and contrast of the image, and make the video picture delicate Smooth, long-time viewing is not easy to fatigue; with inverse gamma correction technology and point-by-point brightness correction technology, the dynamic picture display is more real, natural, unified and consistent.
