In addition, budget constraints may make mid-range refresh rates more attractive for projects that prioritize cost-effectiveness.

In addition, the choice of refresh rate should be based on the type of content. Higher the refresh rates can reduce motion blur and enable smoother playback, adding to the benefits of high-action content such as sports broadcasts or fast-paced games.

How to increase the LED display refresh rate?

If you’re experiencing problems with a low refresh rate on your LED display, here’s how to improve it:

  • Check your hardware: Make sure your driver IC supports a high refresh rate. If not, you may need to replace it with one that does.
  • Examine the PCB design: Look at your device’s PCB design or change the scan mode. Consider increasing the number of driver ICs to increase processing capability.
  • Choose high-quality driver ICs: Choose high-quality driver ICs, such as ICN2153 or MBI5252. However, installing new ICs can be tricky. It’s safer to contact a professional or your supplier for assistance.
  • Update your software: The software you use can affect the refresh rate of your device. Choose software with better performance options.

Choosing the right refresh rate for your LED display is a decision that needs to be made on a case-by-case basis. Here are the factors you should consider when making your choice:

1. Indoor vs. outdoor applications

Indoor screens: Indoor LED displays typically benefit from higher refresh rates due to controlled lighting conditions and closer viewing distances. In environments such as conference rooms, shopping malls, museums, etc., a higher refresh rate ensures that text and images are clear, flicker-free and blur-free, enhancing the viewing experience. Especially in cases where the viewer is exposed to the screen for a long period of time, a higher refresh rate reduces eye fatigue and improves the readability of the content.

Outdoor screens: For outdoor screens used in applications such as digital billboards, stadium displays and public transportation information boards, refresh rate is still important, but the considerations have changed slightly. The perceived benefits of ultra-high refresh rates may be less obvious due to longer viewing distances and the presence of natural light. However, higher refresh rates are good for drawing attention through dynamic content and reducing glare in bright sunlight. Balance is key; while you may not need the high end refresh rates required for close indoor viewing, choosing a 1920 HZ or 3840 HZ refresh rate that is appropriate for your content will remain crisp and engaging in varying outdoor conditions.

2. Budget Considerations

Cost vs. performance: Higher refresh rates mean higher costs, not only in terms of the initial purchase price, but also in terms of the infrastructure needed to support the refresh rate, including more powerful processors and potentially more complex installation and maintenance requirements. Evaluate your project budget to determine which refresh rate range provides the best balance of performance and cost. 

3. Occasions and content types

Content dynamics: The nature of the content you plan to display can significantly affect the ideal refresh rate. For high-speed sports, competitive gaming events, or any fast-paced and detailed action, a higher refresh rate is critical to capturing every moment clearly and smoothly. Higher refresh rates for LED displays ensure that fast-moving objects are displayed smoothly on the screen, enhancing realism and audience engagement.

Type of event: The type of event or application also plays a key role. For example, in trade shows, exhibitions and high-end retail environments, displaying product details in the clearest possible way can influence customer perceptions and behavior, so higher refresh rates will benefit. Conversely, for general signage or information displays with more static content, a lower refresh rate may be sufficient.

4. Viewing Distance and Audience Mobility

Viewing distance: The optimal refresh rate also depends on the viewer’s distance from the screen. In indoor environments, closer viewing distances require higher refresh rates to prevent flickering and ensure image stability, which can prevent viewer discomfort or eye strain.

Viewer Movement: Consider the movement of the viewer. In environments where viewers are moving quickly, such as airports or subway stations, a higher refresh rate can make dynamic content more readable and impactful, even during brief encounters.

Beyond Screen’s Refresh Rate: Other Factors Affecting LED Screen Purchases

While it’s true that refresh rate and frame is a key parameter when choosing an LED screen, it’s only a small part of the puzzle. In order to make an informed decision, it’s important to consider the other factor. Here are a few tips:

1. LED Resolution

Detail and clarity: The resolution of an LED screen is the total number of pixels used to form the displayed image. Higher resolution means more pixels are used, resulting in finer detail, sharper images, and the ability to display more content on the screen without loss of clarity. It is especially important for screens that are viewed up close, where the viewer can recognize individual pixels. High-resolution screens are ideal for detailed visual presentations, complex graphics and text-heavy content.

2. Contrast

Image depth and realism: Contrast plays a key role in the vividness and realism of the image on the screen. It is the difference in brightness between the brightest white and the darkest black that the screen can display. A higher contrast ratio means the screen can produce deeper blacks and brighter whites, enhancing the overall depth and realism of the image. High-contrast LED screens are commonly used in high-end settings, such as digital theaters, high-end retail displays, and PR professional-grade presentations.

3. Brightness

Visibility in various lighting conditions: Brightness (measured in nits) indicates the amount of light emitted by a screen and is especially important for outdoor LED screens. High brightness levels ensure that displays remain visible and clear even in direct sunlight. For indoor applications, the required brightness may be lower, but the ability to adjust brightness to ambient light conditions can improve visibility and viewer comfort.

4. Color Accuracy

Lifelike and vivid displays: The ability of LED screens to accurately reproduce color is critical for many applications. Color accuracy ensures that the tones displayed on the screen match the original content. For brand logos, artwork, and when specific color palettes need to be matched, screens with high color fidelity provide more vivid, lifelike visuals that enhance the viewing experience for advertising, exhibitions, and creative displays.

5. Viewing angles

Consistent image quality from all angles: Viewing angle determines how well image quality is maintained when viewed from different positions relative to the screen. A wider viewing angle means that the screen maintains consistent brightness, contrast and color accuracy even when viewed from acute angles.

6. Durability and reliability

Longevity and maintenance: Over time, the build quality and design of an LED screen affect its durability and reliability. Outdoor screens, in particular, need to be robust enough to withstand a wide range of weather conditions, and all screens benefit from high-quality components that reduce the need for frequent maintenance. 


Choosing the right refresh rate for your LED display is not just a parameter choice. You are better off optimizing the viewing experience for your specific needs and occasion.
