It is very important to understand the concepts of Pixel Pitch and Matrix before you set out to purchase an LED sign. Understanding what these two sign measures mean can save you thousands of dollars on your sign purchase. It can prevent overbuy on an overkill display system. It can also protect you from ever having to replace a recently purchased sign because of display quality issues arising from an incorrectly ordered previous purchase!
Many sign companies sell LED signs based on the physical sign size, not the pitch and matrix, and this causes huge problems for consumers. Of all the possible metrics a sign can be quantified with, sign dimension is probably the single worst indicator of sign application suitability, performance, image quality, and general capabilities. The only thing size tells you is whether or not a sign can fit into a physical space. It offers no insight into what the performance capabilities are the sign, or if it can handle the application you intend to have it doing once built and installed.
Pitch and matrix on the other hand give you an excellent idea on the display capability, and optimal viewing distances for a sign.
Let us set the record straight with this short informational to teach you what pitch and matrix are, and how you should use this knowledge.
