Why do you always have sweeps on your display? Refresh rate is the key

​​Q: How do lags and stripes seen by the naked eye produce? ​ ​
The refresh frequency directly determines the consistency of screen switching. When the refresh rate is below 1920Hz, the camera shooting or the viewing angle of the human eye can appear​ ​Horizontal water ripples​ ​and​ ​Dynamic drag​ ​. For example, when the stage light chasing light swept across the screen, the low-sweeping screen may cause obvious flickering, affecting the performance effect.

Three major scenarios tell you: How to save money and worry-free with high refresh rate

​​Q: What actual value can you get from spending extra money? ​ ​

1. ​​Reduce equipment loss cost​​

   • The load of the driver chip with high flush screen (≥1920Hz) is reduced by 40%, reducing component aging caused by heating.​ ​Extend screen life by 2-3 years​​；
   • With intelligent brightness adjustment technology, outdoor screen power consumption is reduced by 25%.​ ​10㎡ screen saves more than 5,000 degrees of electricity per year​​。

2. ​​Avoid performance accident compensation​​

   • If the picture is torn during the live concert, you may face compensation from the organizer. A music festival has been caused by a low screen swipe​ ​Loss of 800,000 yuan per time​​；
   • High-brush technology uses grayscale compensation algorithm to control the signal delay within 3ms to eliminate such risks.

3. ​​Reduce post-maintenance investment​​

   • The modular box design supports single unit replacement, and the maintenance efficiency is improved by 60%.​ ​100㎡ screen maintenance cost is reduced by 30%​​。

A guide to avoiding pits that experts know about

​​Q: What is the hidden trap that the parameter table will not tell you? ​ ​

• ​​Beware of the word game "peak refresh rate"​ ​: Some products are marked "up to 3840Hz", but the actual working frequency is only 50% of the load, so please check it​ ​Continuous operation stability test report​​；
• ​​Grayscale level is more important than refresh rate​ ​: 16Bit high grayscale technology can increase the dark field details of the 1920Hz screen by 50%, avoiding the occurrence of "dead black" areas；
• ​​Testing method​ ​: Use slow motion mode of the mobile phone (240 frames/second) to shoot the screen. If a black line appears, the refresh rate does not meet the standard.

​​Industry Insights​ ​: Among the global stage equipment failure cases in 2024, 67% were related to mismatch in display equipment parameters. The essence of choosing a refresh rate technology that truly adapts to the scene is​ ​Use 10% of the initial investment to avoid 90% of the late risks​​。
