  The scanning method of full-color LED advertising screen is mainly divided into static scanning and dynamic scanning.What are the differences between them?Take a look with Ddon Visual today:

  first、Static Scanning:

  Static scanning,also known as multiplexing,is a technique where each row or column of LEDs in the display is driven independently.In other words,the LEDs in the same row(or column)are turned on or off simultaneously.This is done in a sequential manner,where each row is illuminated for a very short period of time before switching to the next row.This cycle happens so fast that the human eye perceives all the rows as being illuminated simultaneously.

  1、Advantages of Static Scanning:

  Simplicity:Static scanning requires less complex electronics and circuitry.

  Lower Power Consumption:Since only one row or column is illuminated at a time,the overall power consumption can be lower compared to dynamic scanning.

  2、Disadvantages of Static Scanning:

  Limited Brightness:Static scanning might limit the overall brightness of the display due to power restrictions and heat generation.

  Smaller Displays:Static scanning is more suitable for smaller displays due to its limitations in brightness and power efficiency.

  second、Dynamic Scanning:

  Dynamic scanning,also known as active matrix or multiplexed matrix driving,is a technique that involves driving individual LEDs in a non-sequential manner.Each LED is controlled independently,allowing for higher brightness and better control over the display.

  1、Advantages of Dynamic Scanning:

  Higher Brightness:Dynamic scanning enables higher brightness levels because LEDs can be turned on for longer periods and driven at their maximum rated power.

  Better Image Quality:Dynamic scanning allows for smoother and more detailed images since each LED can be controlled individually.

  Suitable for Large Displays:Dynamic scanning is better suited for larger displays as it can maintain consistent brightness and image quality across the entire display area.

  2、Disadvantages of Dynamic Scanning:

  Complexity:Dynamic scanning requires more complex electronics,often including thin-film transistor(TFT)arrays or other active components.

  Higher Power Consumption:Due to driving multiple LEDs simultaneously,dynamic scanning can consume more power compared to static scanning.

  In general,static scanning is more suitable for scenes with higher display brightness requirements,stability and response speed,especially for some scenes showing still images and text,while dynamic scanning is suitable for some scenes with relatively high refresh rate requirements,such as playing animation,video or dynamic image scenes,users choose the scanning mode at the same time,Just choose according to the needs of your project.China Ddon Visual focuses on the development,production and sales of high-quality full-color LED display,providing full-color LED display module,LED stage rental screen,LED advertising screen spot wholesale and on-site construction,supporting the customization and development services of shaped LED display,if you need assistance with related projects,welcome to call Ddon.We will provide you with a full range of product solutions and quality service.
