In today’s digital age, LED displays, as an important medium for information dissemination, have been widely applied across various fields. Whether it’s commercial advertising, stage performances, or public information displays, LED displays are favored by the market for their high brightness, high definition, and flexible splicing capabilities. However, many people may not fully understand the size specifications and calculation methods for LED displays. Today, we will dive into this topic to help everyone better understand and apply LED displays.

1. Pixel Pitch Calculation: Unveiling the Size Secrets of LED Unit Boards

The clarity of an LED display largely depends on pixel pitch, which refers to the distance between two adjacent LED lights. Different pixel pitches correspond to different unit board sizes. For example, the P2.5 model unit board has a length and width of 320mm and 160mm, respectively, with a pixel pitch of 2.5mm. Through simple calculations, we can determine the arrangement of LED lights on the unit board and understand the overall composition of the display.

2. LED Display Size Calculation Method: Determining Four Key Factors

  1. Clarify Display Needs: First, identify your display needs, including the purpose of the display, viewing distance, and audience size. This will help you choose the appropriate pixel pitch and unit board size.

  2. Calculate the Required Number of Unit Boards: Based on the overall size of the display and the size of the unit boards, calculate how many unit boards are needed. This usually involves simple division, such as dividing the total length by the length of the unit board and the total width by the width of the unit board, then rounding to the nearest whole number.

  3. Consider Seams in the Splicing Process: When splicing multiple unit boards together, you need to consider the impact of the seams between boards. Different splicing methods (such as flat seams, V seams, etc.) will create different seam widths, which should be accounted for during the calculation.

  4. Determine the Actual Size: Finally, based on the number of unit boards and their dimensions, calculate the actual size of the display. This will serve as an important reference for purchasing and installing the display.

3. Indoor LED Display Calculation: Precisely Matching Requirements for a Perfect Display

Indoor LED displays are widely used in various indoor settings, offering high brightness, high definition, excellent color reproduction, energy efficiency, and long lifespan. Common indoor LED displays range from P1.25 to P3, with the following specifications:

  • P1.25 full-color LED display: 320mm × 160mm
  • P1.53 full-color LED display: 320mm × 160mm
  • P1.66 full-color LED display: 320mm × 160mm
  • P1.83 full-color LED display: 320mm × 160mm
  • P1.86 full-color LED display: 320mm × 160mm
  • P2.0 full-color LED display: 320mm × 160mm
  • P2.5 full-color LED display: 320mm × 160mm
  • P3.0 full-color LED display: 192mm × 192mm

Different brands may have slight variations in their sizes.

How is the display size calculated?

In indoor environments, the size of the LED display needs to be precisely calculated according to actual needs. For example, for a 5m long and 4m wide LED display, if you choose a P2.5 full-color LED display, you need to calculate how many unit boards are required to assemble this size. By dividing the total length and width of the display by the length and width of the unit board and rounding to the nearest whole number, you can determine the number of unit boards needed. Then, multiplying this number by the size of a single unit board will give you the actual length and height of the display.

  1. How many boards are needed for the length and width of the screen?

    • Length: 5000 ÷ 320 = 15.6, round up to 16 boards
    • Width: 4000 ÷ 160 = 25, so 25 boards
  2. What are the actual installation dimensions of the screen?

    • Length: 320 × 16 = 5120mm
    • Width: 160 × 25 = 4000mm
    • The total screen area is: 5.12 × 4 = 20.48㎡

Indoor LED displays, with their diverse types, superior performance, and wide range of applications, have become a leader in the modern indoor display market. When selecting a display, users should consider factors such as actual needs, budget, and usage environment.

4. Outdoor LED Display Calculation: Adapting Flexibly to Various Scenarios

Outdoor LED displays are devices that can be installed outdoors, based on complex technology systems such as microcontroller, LED display, and multimedia technology. They feature high brightness, high transparency, high definition, and high refresh rates, making them widely used in advertising, festive events, sports competitions, traffic signage, urban construction, and commercial displays.

The calculation method for outdoor LED displays is slightly different from that for indoor displays, though the basic principles remain the same. Outdoor LED displays are usually spliced together using cabinets. Common outdoor LED displays range from P2.5 to P10, with the following specifications:

  • P2.5 full-color LED display: 320mm × 160mm
  • P3 full-color LED display: 192mm × 192mm
  • P4 full-color LED display: 320mm × 160mm
  • P5 full-color LED display: 320mm × 160mm
  • P6 full-color LED display: 192mm × 192mm
  • P8 full-color LED display: 320mm × 160mm
  • P10 full-color LED display: 320mm × 160mm

1. Module Size Calculation Formula

Necessary conditions: pixel pitch, module resolution

  • Module (unit board) length = pixel pitch × module (unit board) length in pixels
  • Module (unit board) width = pixel pitch × module (unit board) width in pixels

Example: For a P5 module with a resolution of 64×32:

  • P5 module length = 5 × 64 = 320mm
  • P5 module width = 5 × 32 = 160mm

Thus, the module size of the outdoor full-color P5 product is 320×160mm.

2. Total Display Area Calculation Formula

Total display area = number of modules used × area of a single module

Example: A customer needs to build a P5 (320×160) display with a length of approximately 12 meters and a height of 9 meters. What is the total area of the display?

  • Module length = 5 × 64 = 320mm = 0.32m
  • Module width = 5 × 32 = 160mm = 0.16m
  • Number of modules along the length = 12 ÷ 0.32 = 37.5 ≈ 37 modules
  • Number of modules along the height = 9 ÷ 0.16 = 56.25 ≈ 57 modules

The total area of the display = (37 × 0.32) × (57 × 0.16) = 107.98㎡

Currently, outdoor LED displays are playing an increasingly important role in modern society, thanks to their excellent performance and broad application scope.

5. Key Considerations When Choosing an LED Display

  1. Brand and Quality: Choose a reputable brand and high-quality products to ensure the stability and longevity of the display.
  2. After-sales Service: Understand the manufacturer’s after-sales policy to ensure timely solutions in case of any issues.
  3. Installation and Debugging: Choose a professional installation and debugging team to ensure the display’s performance and safety.

6. Conclusion: Master the Calculation Methods to Easily Meet Various Needs

By introducing these methods, we have learned how to calculate LED display sizes, including pixel pitch calculations and the differences between indoor and outdoor displays. By mastering these methods, you can accurately calculate the required LED display size to meet the needs of various scenarios. Whether it’s for commercial advertising, stage performances, or public information displays, LED displays will add more color and vitality to our lives with their superior visual effects and flexible splicing capabilities.
