LED Screens with 1920Hz, 3840Hz and 7680Hz Refresh Rates: How to Choose?

The refresh rate refers to the number of times the screen updates the image per second, usually measured in hertz (Hz). With the continuous progress of technology, LED screens with various refresh rates have emerged in the market, among which 1920Hz, 3840Hz and 7680Hz are the three most common ones. This article will introduce in detail the characteristics and applicable scenarios of these three types of LED screens with different refresh rates to help you make a wise choice.

 

                  

LED Screens with a 1920Hz Refresh Rate

 

The 1920Hz refresh rate is usually referred to as "standard refresh" and is widely applied in the field of LED display screens. This refresh rate indicates that the screen can update images 1920 times per second, which significantly reduces the flickering phenomenon and makes the pictures smoother and clearer. The following are the main features and applicable scenarios of LED screens with a 1920Hz refresh rate.

 

Visual Experience: The 1920Hz refresh rate is already high enough that the naked eye can hardly detect any flickering. It is suitable for viewing both static and dynamic images.

Usage Scenarios: Indoor full-color LED display screens usually adopt a 1920Hz refresh rate. It is applicable to scenarios such as commercial advertisements, conference presentations, and stage backgrounds.

Advantages: It has a high cost-performance ratio, can provide a good viewing experience, and will not cause visual fatigue.

 

LED Screens with a 3840Hz Refresh Rate

The 3840Hz refresh rate is known as "high refresh". This refresh rate further enhances the display effect, especially when it comes to dynamic images and shooting. The following are the main features and applicable scenarios of LED screens with a 3840Hz refresh rate.

 

Visual Experience: The 3840Hz refresh rate almost completely eliminates the flickering phenomenon, making the pictures more detailed and smoother, and thus the viewing experience is more comfortable.

 

Shooting Effects: The high refresh rate can reduce the moiré pattern phenomenon of the screen during photography and videography, making the shooting pictures clearer. In the case where the camera shutter speed is generally fast, the 3840Hz refresh rate can ensure that there are no ripples in the shooting pictures.

 

Usage Scenarios: It is suitable for occasions that require frequent shooting and publicity, such as large-scale concerts, live broadcasts of sports events, and studio shootings.

Advantages: The display effect is more excellent, especially outstanding in shooting and high-speed motion scenes.

 

 

LED Screens with a 7680Hz Refresh Rate

 

The 7680Hz refresh rate is one of the most high-end refresh rates on the current market, and its display effect can be described as ultimate. The following are the main features and applicable scenarios of LED screens with a 7680Hz refresh rate:

 

Visual Experience: The 7680Hz refresh rate almost reaches the limit that the human eye can't perceive. The pictures are smooth without any ghosting, and the visual experience is extremely comfortable.

Shooting Effects: Under the ultra-high refresh rate, even high-definition and high-speed lenses can't capture any ripples, and the shooting effect is the same as that seen by the naked eye.

Usage Scenarios: It is suitable for high-end commercial exhibitions, virtual shootings, large-scale conferences, and high-end entertainment activities.

Advantages: It has excellent display and shooting effects, and is suitable for occasions with extremely high requirements for image quality.

 

How to Choose?

When choosing the refresh rate, several factors need to be considered comprehensively:

 

Usage Scenarios: If it is mainly used for indoor advertising displays, conferences and other static and low-speed dynamic scenarios, a 1920Hz refresh rate is sufficient. If frequent shooting and publicity are required, or high-speed motion scenes need to be displayed, a 3840Hz or even 7680Hz refresh rate is more appropriate.

Budget: Generally, the higher the refresh rate, the higher the cost. When the budget is limited, it is necessary to weigh the importance of the refresh rate against other parameters (such as brightness, contrast, resolution, etc.).

Technical Requirements: A high refresh rate requires a high configuration to support it, including high-performance driver chips and power supply systems. When making a choice, it is necessary to ensure that the entire system can meet the requirements of a high refresh rate.

 

In conclusion, LED screens with 1920Hz, 3840Hz and 7680Hz refresh rates each have their own advantages and are suitable for different usage scenarios. When choosing, it is necessary to consider the actual needs, budget and technical requirements comprehensively to select the LED screen that best suits you.
