The refresh rate is an important parameter of the led display which is related to the led viewing performance directly.
What is the refresh rate of LED display？
The refresh rate is the number of times per second that the image can be scan. It’s measured in hertz (Hz) and may also be referred to with terms like scan rate, horizontal scan rate, frequency, or vertical frequency.
What’s the effect on the LED display and human eyes?
It will directly affect the LED display’s performance. The higher the refresh rate the more stable and clearer the display image and a smaller impact on the human eyes. The lower refresh rate will get bigger flicker and Jitter of the display image, and faster get fatigued to human eyes. So the refresh rate also makes a big difference on the led display’s price.
Since the refresh rate relates to the flicker and jitter of the screen, does it mean the refresh rate higher then the led is better?
Refresh rate relates to many parameters of the led display, like the grayscale, resolution, etc. The higher refresh rate the lower grayscale, so only find a balance between all the parameters that can achieve the best performance of the led screen.
What influences the do refresh rate of the led display?
1.IC brand and model. It can be divided into high refresh rate IC, common IC and low refresh rate IC.
2.Control card load capability. For one receiving card usually the biggest load capacity is 256x256pixel, but we usually control within 192x192pixel to achieve smooth loading.
3. Serial frequency also called at the clock frequency.
4.Grayscale. Higher grayscale will be lower the refresh rate.
5. Driving board.
