In modern display technology, refresh rate is one of the key indicators of a screen's performance. The refresh rate refers to the number of times per second the screen updates its image, measured in hertz (Hz). For example, a 60Hz refresh rate means the screen refreshes 60 times per second. Simply put, the higher the refresh rate, the faster the screen updates, resulting in smoother image display.
The refresh rate is a core factor affecting the viewing experience. It directly impacts the smoothness and stability of images, especially when watching dynamic videos or displaying fast-moving scenes. Displays with high refresh rates can provide smoother and more realistic visuals, enhancing the viewer’s immersion and comfort.
Improved Viewing Experience:
On LED displays with a low refresh rate, the human eye may perceive flickering, which can lead to visual fatigue or discomfort during prolonged viewing. A high refresh rate display effectively reduces flickering, offering a more stable and fluid image, which improves overall comfort.
Enhanced Visual Quality:
Low refresh rate LED displays may exhibit issues such as scan lines, image stuttering, ghosting, or screen tearing. When filming, flickering is often visible on these screens. A higher refresh rate helps eliminate these issues, providing clearer, more coherent visuals, and enhancing the overall viewing experience. This is especially important for fast-moving content, such as live sports events, where a high refresh rate ensures smooth motion without blurring, allowing viewers to catch every detail as if they were at the event.
Low Refresh Rate Display and Standard Refresh Rate Display
While both refresh rate and frame rate involve image display and updates, they serve different roles. Understanding their relationship is key to choosing the right display device.
Refresh rate refers to the number of times the screen updates its image per second, determined by the display device’s capabilities. It defines how often the display can refresh the image, affecting the smoothness of the visuals.
Frame rate, on the other hand, refers to the number of frames per second (FPS) generated by the content source (e.g., video or gaming engine). For example, 30fps means the content consists of 30 different frames per second. Frame rate is determined by the hardware (like the graphics card or processor) and software (such as games or video players) of the content source.
The refresh rate and frame rate are interrelated, and optimal visual performance occurs when both are well-matched. If the refresh rate exceeds the content’s frame rate (e.g., a 120Hz display with a 60FPS source), the display cannot show all the frames, causing some frames to be skipped. Conversely, if the refresh rate is lower than the content’s frame rate (e.g., a 60Hz display with a 120FPS source), the display cannot fully show all the frames, potentially resulting in stuttering or choppy images. Therefore, ensuring proper synchronization between refresh rate and frame rate is essential for the best viewing experience.

Selecting the appropriate refresh rate is crucial for ensuring a smooth and seamless viewing experience. The ideal refresh rate should be adjusted based on the specific application and viewer needs. For everyday display devices, 60Hz and 120Hz are common choices, with 120Hz offering a notably smoother viewing experience. Higher refresh rates, such as 1920Hz, 3840Hz, or even 7680Hz, are primarily used in fast-moving visual scenarios as well as commercial advertising, virtual reality, and film production in professional settings.
RGBshine deeply understands the refresh rate demands of various application scenarios and offers flexible solutions that match the most suitable combination of parameters. For example, in high-demand professional environments, we recommend a combination of an ultra-high 7680Hz refresh rate with high brightness and contrast to deliver exceptional visual performance. For more standard applications, we provide cost-effective solutions that help clients achieve the best balance between performance and cost.
