In today's rapidly advancing technology, LED display advertising screen have become an indispensable part of our lives. From bustling commercial districts to dazzling concerts, from solemn conference rooms to passionate sports events, LED displays illuminate every corner with their unique charm. However, when we talk about LED displays, we often hear the professional terms "32 scan" and "64 scan". So, what exactly are they and what different? We will provide a detailed introduction from this article.
1. Scanning method
In LED display screens, 32 scan means that the screen is divided into 32 areas and sequentially lit up within each frame time; And 64 scan divides the screen into 64 areas for scanning. More scanning partitions (such as 64 scans) mean that fewer LED’s are controlled in a single area during each scan, which can reduce the current load on each area and help improve screen stability and extend lifespan.
2.Refresh rate
Generally, a 64 scan LED screen can provide a higher refresh rate compared to a 32 scan screen because it scans more times per unit time, which helps eliminate flickering on the screen and is more friendly to dynamic images and photography recording.
3.Brightness and power consumption
In theory, due to the small number of LED’s driven in each 64 scan, the overall brightness may be slightly lower than in 32 scans at the same time (if other conditions remain unchanged). However, in reality, manufacturers usually balance brightness by adjusting the driving current, so the final brightness performance may not differ significantly. Meanwhile, power consumption may also vary depending on the scanning method, but this difference is not always significant relative to the overall power consumption of the screen.
4.Cost and complexity:
On the surface, the 64 scan module reduces by half compared to the 32 scan chip. In theory, there will be a decrease in brightness, performance loss, grayscale loss, and low brightness colors that cannot be removed, which can easily lead to color spots and color differences. Due to cost control, how to reduce costs without reducing functional effects, with the support of the 64 scan driver IC, serial line tubes are used instead of the decoding method of 138, directly allowing LED’s to enter the 64 scan field.
5.visual effect
Due to the large number of simultaneously lit LED lights, 64 scan may be slightly inferior to 32 scan in terms of refresh rate and display effect. At the same refresh rate, 64 scans may exhibit a certain degree of blurring or ghosting, especially when displaying high-speed moving images. Due to the reduced strong refresh rate of the chip, the light decay of the lamp seriously affects its lifespan, increases the failure rate, and causes phenomena such as long caterpillars.
Overall, the main difference between "32 scan" and "64 scan" lies in the precision and energy consumption of scanning. For application scenarios that require higher brightness and clarity, a "32 scan" LED display screen can be selected; For application scenarios that focus more on energy consumption, a "64 scan" LED display screen can be chosen. However, it should be noted that the choice of these two scanning methods is not absolute and needs to be comprehensively considered based on specific application requirements and budget.
