What is the difference between 1/2 scan, 1/4 scan, 1/8 scan, 1/10 scan, 1/16 scan, 1/20 scan, 1/23 scan, 1/32 scan, 1/40 scan, 1/64 scan of LED display?

What is the difference between 1/2 scan, 1/4 scan, 1/8 scan, 1/10 scan, 1/16 scan, 1/20 scan, 1/23 scan, 1/32 scan, 1/40 scan, 1/64 scan of LED display?

 

 

 

 

 

LED display scanning methods, such as 1/2 scan, 1/4 scan, 1/8 scan, 1/10 scan, 1/16 scan, 1/20 scan, 1/23 scan, 1/32 scan, 1/40 scan, and 1/64 scan, primarily differ in the proportion of rows illuminated simultaneously compared to the total number of rows in the entire display area. Let's delve into the details:

 

 

I. Definition of Scanning Methods
Scanning methods refer to the proportion of rows that are illuminated simultaneously within a given display area, compared to the total number of rows. This proportion determines the refresh rate and brightness performance of the display.

 

 

II. Differences Between Various Scanning Methods

1/2 Scan:
Half of the total rows in the display area are illuminated simultaneously.
The refresh rate is relatively fast, but brightness may not be as high as static scanning.

 

1/4 Scan:
One-quarter of the total rows in the display area are illuminated simultaneously.
Brightness is lower compared to 1/2 scan, but hardware costs are also reduced.
In some cases, increasing the refresh rate can reduce flickering and enhance image stability.

 

1/8 Scan:
One-eighth of the total rows in the display area are illuminated simultaneously.
Brightness is further reduced, making it suitable for applications with lower brightness requirements.
Lower costs make it ideal for large-area displays.

 

1/10 Scan:
One-tenth of the total rows in the display area are illuminated simultaneously.
It falls between 1/8 scan and 1/16 scan in terms of brightness performance.

 

1/16 Scan:
One-sixteenth of the total rows in the display area are illuminated simultaneously.
Brightness is lower, but costs are also lower.
Suitable for applications with low brightness requirements and cost constraints.

 

1/20 Scan, 1/23 Scan:
These two scanning methods fall between 1/16 scan and 1/32 scan.
They offer moderate brightness performance and relatively low costs.
Suitable for specific applications with unique requirements.

 

1/32 Scan:
One-thirty-second's worth of the total rows in the display area are illuminated simultaneously.
Brightness is lower, but costs are even lower.
Ideal for large-area displays with low brightness requirements.

 

1/40 Scan, 1/64 Scan:
These two scanning methods provide even lower brightness but also lower costs.
Suitable for applications that require very low brightness and have large display areas.

 

III. Other Considerations
Brightness vs. Cost: Generally, as the scanning ratio decreases (i.e., the denominator increases), brightness decreases but costs also decrease. Therefore, the choice of scanning method should be based on specific needs and trade-offs.

 

Refresh Rate: The refresh rate is closely related to the scanning method. A higher refresh rate can reduce flickering and enhance image stability. When selecting a scanning method, ensure that the refresh rate meets the application requirements.

 

Application Scenarios: Different scanning methods are suitable for different application scenarios. For example, indoor full-color LED displays typically use higher scanning methods such as 1/16 scan or 1/32 scan to ensure brightness and display quality; whereas outdoor full-color LED displays may use 1/4 scan or lower scanning methods to reduce costs.
