What is the LED Screen refresh Rate? How many are there?

Now the indoor and outdoor LED display application more and more, whether it is the airport, stores, conference rooms and studios can see the figure of the led display. That in the purchase of pixel pitch led may ask how the screen refresh rate, refresh rate is how many words, that today to talk about the LED Screen refresh Rate.

What is the LED Screen refresh Rate?

LED display refresh rate, also known as the “visual refresh frequency”, “refresh frequency”, LED Screen refresh Rate means the rate of screen update, that is, refers to the display screen per second by the number of times the screen Mu repeat display, screen refresh rate in Hertz units, usually abbreviated as “Hz”. Usually abbreviated as “HZ”. For example, a screen refresh rate of 3840Hz means that the image is refreshed 3840 times in one second. When you take photos or videos of the content of the LED display screen, found that the photos they took or recorded photos have vertical or horizontal stripes or blurred, it means that the LED Screen refresh Rate of the ghost.


What are the common refresh rates of LED display?

Common refresh rates such as 960Hz, 1920Hz, 2880Hz, 3840Hz, etc. are usually used for led display small. 960Hz is often referred to as the low brush, 1920Hz is called the universal brush, 3840Hz is called the high brush. Generally high refresh rate is mainly used to improve image quality, reduce image tearing and blurring, especially in some professional application scenarios, such as stage performances, competitions, billboards, and places that require high-quality video surveillance.The relationship between the LED refresh rate and the picture quality is also very important, and a high refresh rate can effectively reduce motion blurring and dragging, and improve the clarity and realism of the picture. Therefore, the refresh rate is a very important parameter to pay attention to when choosing an pitch led display.

What is the impact of the refresh rate of led screen?

LED refresh rate is a key factor affecting the quality of the screen and visual effect. Generally speaking, a visual refresh frequency of 3,000Hz or more is a high-efficiency LED display. High refresh rate has a very big impact on the performance and image quality of LED display. 1920Hz, 2880Hz, 3840Hz, etc. These high refresh rate can provide smoother and clearer image display, which is very friendly for displaying the fast movement of objects, high dynamic paradigm content, and the application of high color accuracy requirements. High refresh rate LED display is suitable for applications that require a higher visual experience and more professional occasions, while for general-purpose displays, a lower refresh rate is already sufficient.

Display Refresh Rate Comparison  

The higher the refresh frequency, the more stable the screen display, the smaller the visual flicker, the higher the quality of the image people see, and the video playback is also very smooth. Previously mentioned scenarios when you take pictures or record the content of the video LED display horizontal horizontal stripes, which indicates that the low refresh frequency of the LED display is too low. low refresh frequency of the LED display will lead to video, photography, there are horizontal horizontal stripes outside or drag and tear through the image, but also occurs similar to tens of thousands of light bulbs at the same time flickering image. The human eye in the viewing may therefore produce discomfort, and even cause damage to the eyes.

Difference between LED display refresh frequency and resolution

LED screen resolution refers to the number of pixels visible on the display, usually expressed as the number of horizontal pixels x the number of vertical pixels, such as 1920 x 1080.Higher resolution means more pixels on the LED display screen, so it can display more image details and higher clarity, and visually feel the details of the picture quality of a higher definition.The refresh frequency of LED display screen focuses on the image updating The refresh rate of LED display focuses on the speed of image update, and the resolution focuses on the clarity and details of the image. The combination of the two have a great impact on the performance of the display and user experience, so when choosing LED display need to balance the refresh frequency and resolution according to the specific use and demand, different application scenarios require different display performance, need to users according to the use of scenarios and budgets to compromise to achieve the best visual effect.
Secondly. Is the essence of the difference, LED display refresh rate and LED driver chip, when the use of ordinary chip, the refresh rate can only reach 480Hz or 960Hz, while the LED display is used in the double lock driver chip, then the refresh rate can reach 1920HZ, when the use of high-level PWM driver chip, LED display refresh rate can reach 3840Hz. The resolution of the LED display is related to the physical size of the LED display, the larger the size of the LED display, the higher the resolution, in addition to the resolution is also related to the LED bead pitch, the smaller the pitch the higher the resolution.



If we usually watch the LED display time is not long, and there is no shooting requirements, then the use of low refresh rate can be, if you often need to watch for a long time, and often need to take pictures or shoot a video to watch, then you need to use a high refresh rate of the LED display. High refresh rate LED display price is much higher than the low refresh rate, so the specific choice of which refresh rate of the product, or according to the specific use of the view, according to different application requirements, choose the display applicable to specific scenes, in order to achieve the best visual effect and user experience. Low refresh LED display is just the eyes to watch and not much impact, is not perceived whether the screen flickers, do not need to take pictures or video cases have no impact, can save a lot of budget, of course, if the picture quality requirements of a high more professional specific scenes or cost budget is sufficient, then naturally choose a high refresh rate of the LED display is better.
