PIXEL SIZES: WHAT ARE THEY AND WHAT DO THEY MEAN?
Sign people talk a lot about pixel pitch. But what does that mean? Digital signs are referred to by their pixel pitch, like P5 mm, P6 mm, and P10 mm. Basically, the pixel pitch is the resolution of the sign. A sign's resolution is dependent upon the distance between each pixel, which is typically comprised of a cluster of three LEDs – one red, one green and one blue (or just one, referred to as SMD). The distance is measured in millimeters and the smaller the pitch, the closer together the LEDs are placed. Smaller pitches give you a better resolution and crisper, more lifelike images!
LED signs are often talked about in terms of sign “resolution”. Let us make this simple for you: the resolution is just the number of pixels high by the number of pixels wide your sign will be! However, let us be clear... two signs that have the same outside dimensions but are not the same pitch will each have a different resolution. For instance, a P10mm sign that is 37” x 13"” has a resolution of 96 x 32 while a P5mm of the same size has a resolution of 192 x 64. The higher the resolution, the better the picture!
Optimal viewing distance is the point at which the individual pixels begin to blend together to form a smooth, consistent image. Generally speaking, signs with a short distance between each pixel, such as P5 mm or P6 mm models, are best for close viewing distances. Wider pixel spacing, found on P10 mm models, are better for locations where the sign will be installed at a great height or are farther away from traffic.
We use industry standard, gold star Novastar products which offer full motion video (up to 30 frames per second) and whole-sign color calibration for the truest, most lifelike images. If you plan to use your sign to display video content, you’ll want to be sure to select a sign with a width-to-height aspect ratio that closely matches the format of the video content. Take some time to think about how you will use your sign, because sign size and resolution can impact the type of message content you’ll be able to display. Smaller signs are best suited for text and simple logos, while larger sign sizes have more flexibility displaying a variety of layouts like logos, text, and product images. More detailed images should always be displayed on a higher resolution sign.
