UNDERSTANDING LED SIGNAGE
What is pixel pitch?
Pixel pitch is a standard measurement that indicates the resolution of a digital sign based on the spacing of LED clusters (also known as pixels). The accepted standard is measuring from the center of one pixel to the center of the next — both vertically and horizontally. This means that an LED sign with a pixel pitch of 10 mm has pixels spaced 10 millimeters apart. This is also referred to as a 10-mm resolution.
What is pixel matrix?
The matrix of a sign is calculated based on the number of pixels on each module, multiplied across the entire sign. For example our 12.06" x 12.06" 10-millimeter module contains 1024 pixels in a 32-by-32 matrix (32 rows of pixels, each containing 32 pixels, or 32 times 32 =1024). For a 10-mm sign with a display area that measures 3 feet by 5 feet, the matrix would be 96 by 160 (3 times 32 pixels per foot, and 5 times 32 pixels per foot). To get the number of pixels on the entire sign, multiply 96 times 160 for a total pixel count of 15,360 in the viewable area.
Can you explain a signs viewable area?
Two signs of different resolutions with an identical matrix will have different viewable areas. For example a 19mm and a 12mm sign are both available with a matrix of 96 by 144, but the 19mm sign would have to be 44 percent larger to achieve it. The viewing area for the 12 mm would be 4 feet by 6 feet, compared to a viewing area for the 19mm of 6 feet by 9 feet. The pixel pitch would be higher for the 12 mm, and would better utilize the signs viewing area, particularly at close range.
Pitch, matrix, viewing area and module size are all important factors when purchasing an LED sign. When considering cost, you may pay less because you're getting less. The results will show in the size of the display and detail of your content.
