Choose the Right Pixel Pitch of the Flexible LED Film!

Pixel pitch is the core parameter of Flexible LED Film!, which directly affects the display effect, viewing distance and cost budget.

On a flexible LED film screen, a smaller pixel pitch means less space between pixels, which allows for a higher pixel density and higher screen resolution, resulting in a more detailed and clearer display.However, the pixel pitch is not as small as it should be, therefore,this article reveals how to realize the best display effect with the lowest cost from two aspects: technical principle, selection formula!

Technical definition of pixel pitch for Flexible LED Film

• Basic Concept:
  • Pixel Pitch=Distance between adjacent pixel centers (unit: mm)
  • Common specifications: P4, P4-8, P6, P8, P10,P16, P16-32, P32, P20-60
• Relationship with resolution:
  • Resolution = Screen size (mm) ÷ Pixel pitch (mm)
  • Example: 1000mm wide screen, P1.5 pitch, resolution = 1000 ÷ 1.5 ≈ 666 pixels
• Relationship with dot density:
  • Dot Density (PPI) = 25.4 ÷ Pixel Pitch (mm)
  • Example: P4 pitch, point density = 25.4 ÷ 4 ≈ 6.35 PPI

Selection formula: P value=viewing distance÷2000

• Formula source:
  • Minimum resolution angle of human eye ≈ 1/60 degree
  • Optimal viewing distance = pixel pitch × 2000
• Application case:
  • Conference room scene: viewing distance 3 meters, P value = 3000 ÷ 2000 = 1.5 (choose P1.5)
  • Shopping mall advertising screen: viewing distance of 6 meters, P value = 6000 ÷ 2000 = 3 (choose P3.0)
• Common misconceptions:
  • Error1: The smaller the P value, the better (cost increase 300%, the effect is not obvious)
  • Error 2: the larger the P value the more money (rough picture quality, customer complaints ↑ 50%)

In short, when selecting a crystal film screen, factors such as screen size, resolution and viewing distance need to be considered in order to determine the most suitable pixel pitch for the best display effect and user experience.
