When it comes to LED displays, we often hear two professional terms: 32-scan and 64-scan.But what exactly do they mean? Today, let’s step into the world of LED displays and uncover the mystery behind 32-scan and 64-scan driving modes.

1. What is 32-scan in LED display?

Definition of 32-scan

In LED displays, 32-scan means that within the time of one frame, the screen is divided into 32 independent areas. These areas light up sequentially in order to form a complete image. This scanning mode is similar to stage lighting effects: spotlights illuminate different parts of the stage one by one, ultimately presenting a wonderful performance.

 Working Principle of 32-Scan

The principle of 32-scan is actually quite simple. Just like watching a movie, a movie is composed of consecutive frames, and each frame is made up of countless pixel points.

For a 32-scan LED display, each frame image is divided into 32 independently controlled areas. Within a fixed period, the first area lights up to display part of the picture, then quickly turns off. After that, the second area is illuminated to show another section of the image and also shuts down rapidly. In this way, the 32 areas light up in sequence, eventually forming a complete picture.

Characteristics of 32-Scan

① High efficiency and energy saving: Zoned control reduces unnecessary current load and helps save power consumption.

② Stable display image: Each area lights up in rotation, avoiding heat accumulation and damage risks caused by long-time illumination of a single area.

③ Cost-effective: Suitable for most indoor and semi-outdoor scenarios. It features relatively low cost and is easy for popular application.

 

2.What is 64-Scan in LED display?

 

Definition of 64-Scan

If 32-scan divides the screen into 32 areas for scanning, 64-scan doubles this number. The screen is split into 64 smaller areas that light up one after another in sequence.

This means that within the same period of time, more areas on a 64-scan LED display are illuminated in turn, delivering a finer and more delicate visual performance. This technology further improves the resolution and stability of LED display.

 

Working Principle of 64-Scan

The working principle of 64-scan is similar to that of 32-scan, but with more refined zoning.It is just like cutting a cake into more small pieces. A 64-scan LED display divides each frame into 64 smaller areas. Each small area lights up rapidly in an extremely short time, then switches quickly to the next area. This high-frequency switching delivers a more delicate image with smoother color transition.

Features of 64-Scan

① Ultra-fine image performance: More divided areas mean smaller control units, delivering richer picture details.

② Ultra-long service life: Zoned control further reduces the current load of a single area, extending the service life of the LED display.

③ High brightness and low attenuation: Ideal for outdoor and other scenarios that require high brightness and long-term continuous operation.

 

What are the differences between 32-scan and 64-scan LED display?

 

• Refresh Rate: Generally, 64-scan LED screens deliver a higher refresh rate than 32-scan ones. Thanks to more scanning times per unit time, it effectively eliminates screen flicker and performs much better for dynamic images and camera recording.
• Brightness and Power Consumption: Theoretically, a 64-scan design drives fewer LEDs each time, so its overall brightness may be slightly lower than that of a 32-scan screen under the same conditions. However, our company usually balances the brightness by adjusting the driving current, so the actual final brightness difference is negligible.
• Visual effect: Due to the larger number of LED lights lit simultaneously, the 64-scan version may be slightly inferior to the 32-scan version in terms of refresh rate and display performance. At the same refresh rate, 64-scan may produce a certain degree of blurriness or ghosting, especially when displaying fast-moving images. Forcing a higher refresh rate with fewer driving chips may accelerate the light attenuation of LEDs, seriously shortening the service life.

 

Having learned about the 32-scan and 64-scan technologies for LED displays, each boasts unique advantages and applicable scenarios. When making a selection, we need to take into account specific application requirements, budget and actual needs comprehensively.

You can make the final choice according to your actual application scenarios and demands. Whether it is cost-effective indoor use or high-end outdoor display pursuing ultimate visual effects, our company can provide you with a perfect tailored solution.
