How to Calculate the of Resolution LED Display Module

When selecting an LED display sending box, the following key factors need to be considered:

Resolution Support: The resolution support of the sending box determines the maximum resolution that the display can support. Make sure that the sending box you choose can support the resolution requirements of your display, especially for high-definition or higher-resolution screens.

Maximum Resolution: The maximum resolution of the sending box refers to the highest image resolution it can transmit. For example, if the sending box supports a resolution of 1920×1080, it can drive a Full HD display. However, if your LED display has a higher resolution, such as 4K resolution (3840×2160), you need to select a sending box that supports a higher resolution.

Pixel Load Capacity: The pixel load capacity of the sending box is another important parameter. This determines the total pixel count the sending box can support. Different sending boxes usually specify their maximum pixel load capacity, such as 1.3 million pixels or 3 million pixels. The larger this value, the larger the display area the sending box can support, making it suitable for larger LED screens.

Resolution Adaptation: The resolution support of the sending box not only refers to the total pixel count in the horizontal and vertical directions but also whether it can adapt to the actual resolution of the LED display. Due to the varying pixel arrangements and sizes of LED screens, sometimes it may not perfectly match standard resolutions (like 1920×1080). Therefore, it is essential to choose a sending box that can adapt flexibly to ensure no image stretching or cropping occurs.

Resolution Settings: Some sending boxes come with automatic resolution adjustment features, which can automatically detect the input signal resolution and make the necessary adjustments. Some high-end sending boxes also allow manual resolution adjustment to fit different display needs. If you need to customize the resolution or adapt to special-sized LED screens, this feature will be very useful.

In general, when selecting a sending box, it is essential to clearly define the actual resolution requirements of the LED display and ensure that the sending box can transmit the required resolution signal without distortion. This will maximize display performance and avoid issues like blurriness or distortion.

Calculation of LED Display Resolution:

The resolution (in pixels) of an LED display can be calculated using the following formula:

Resolution (pixels) = Width of the display (in modules) × Horizontal pixels per module × Height of the display (in modules) × Vertical pixels per module

The steps are as follows:

1. Determine the display size: LED displays are typically made by stitching multiple LED modules together. First, determine how many LED modules are included in the display’s width and height.

2. Understand module resolution: Each LED module has its resolution, defined by the number of horizontal and vertical pixels. For example, a P10 module typically has a resolution of 32×16 pixels (32 pixels horizontally, 16 pixels vertically), and a P5 module typically has 64×32 pixels.

3. Calculate the total pixels in width and height:

   • Horizontal pixels = Number of modules in width × Horizontal pixels per module.

   • Vertical pixels = Number of modules in height × Vertical pixels per module.

4. Calculate total resolution: Multiply the total pixels in the horizontal direction by the total pixels in the vertical direction to get the overall resolution of the display.

Example: If you have an LED display made from P10 modules, with a width of 10 modules and a height of 5 modules:

Each P10 module’s resolution is 32 (horizontal) × 16 (vertical) pixels.

• Horizontal total pixels = 10 modules × 32 pixels = 320 pixels.

• Vertical total pixels = 5 modules × 16 pixels = 80 pixels.

Therefore, the resolution of the display is 320×80 pixels.

The Pixel Load of the Main Network Cable:

The pixel load of the main network cable will indeed affect the selection of the sending box model. Generally, each sending box has a maximum pixel load capacity, which refers to the total pixel count it can drive. For example, some sending boxes can support 1.3 million pixels, while others may only support 650,000 pixels. Therefore, it is crucial to ensure that the sending box you choose has a sufficient load capacity to meet the resolution requirements of the display.

Here are several key points when choosing a sending box:

• Maximum Pixel Load Capacity of the Sending Box: Different models of sending boxes have different maximum pixel load capacities. When selecting a sending box, first determine the total pixel count of the display, and then choose a sending box that can support at least that pixel count. For example, if your display's total pixel count exceeds 650,000, you will need a sending box that supports higher pixel load capacity.

• Bandwidth Limit of the Main Network Cable: Typically, a single main network cable can handle a maximum pixel count, generally around 650,000 pixels. If the display’s pixel count exceeds the capacity of a single main network cable, you may need to use multiple cables to distribute the load and support larger resolutions. Some high-end sending boxes support multiple network outputs, allowing multiple cables to simultaneously output, distributing the load and increasing the total load capacity.

• Resolution and Number of Network Output Ports: The multiple network output design of the sending box can divide the display into multiple areas, each of which is driven by an independent network cable. This allows you to increase the total number of pixels supported without changing the overall resolution. For ultra-high-resolution LED display projects, you can choose a sending box that supports multiple network ports or cascading cards.

• Brand and Compatibility of the Sending Box: Different brands of sending boxes have varying load capacities, interfaces, and feature designs. When selecting a sending box, it is recommended to choose one that is compatible with your control card and display screen brand to ensure system stability.

  
  

In summary, when choosing a sending box, you should consider not only its pixel load capacity but also the bandwidth limits of the main network cable and support for multi-port output to meet the high-resolution requirements of the display.
