There is a lot confusion in the industry as to what the difference is between monochrome LED displays and grayscale LED displays. Most of the time people - even ourselves- use the terms interchangeably but there are times when businesses specifically ask for a grayscale or monochrome display presuming there to be a distinction between the two. They know that their needs would better be met by a particular type they may have seen before. So, what is that difference? In general, monochrome and grayscale in the LED sign industry are both used to refer to single color LED displays. Full color LED signs (also called RGB LED display) have a red, a blue, and a green LED diode in each pixel and can display all possible color combinations. In contrast, single color LED displays, as the name indicates, have one single LED diode per pixel and all of the LED lights on the board are the same color. Strictly speaking in some understandings of the term, the LED diodes in an outdoor monochrome LED display only have one level of brightness, so either they are on or they are off. Let’s imagine we have a red monochrome LED display; If the lights are on, that pixel will be red and every LED diode that is turned on will have exactly the same shade of the color red. On the other hand, if the lights are off, that pixel will be black - the standard background color for an LED sign. The perfect monochrome display examples are the LED signs typically found on the highway and used by municipal agencies. Those signs usually only display very simple text and are mostly aimed to notify drivers of road conditions, give directions, or public service announcements. Outdoor grayscale signs also have one color LED diodes, but each light can shine at different levels of brightness, allowing for many shades of the same color. If we go back to our red LED sign example, if it were gray-scale, each one of the LED lights could be displaying a different intensity - or shade- of the color red. That means some of the diodes could be displaying a pinkish-red, while different ones show an orange-red and others a bright-red. This makes gray scale the preferred choice for LED signs that display pictures or videos, since it allows for more definition and shades in the images. In practice, all outdoor gray-scale LED signs could also function as monochrome signs if that is what the business owner prefers. In other words, all of the LED diodes on a gray scale LED board can be set at the same brightness level. Why would a business want to buy an outdoor monochrome or a gray scale LED display? Outdoor LED signs are a powerful advertising tool, in fact, the Small Business Administration calls them the most-cost effective form of advertising, but they require a significant upfront investment. An outdoor grayscale LED display could provide many of the advantages of an LED sign at a significantly lower cost. If the goal of the business is to advertise with text or simple images or videos, gray-scale or monochrome LED signs could be a great, more affordable alternative. There are aesthetic considerations too depending on the look the business is seeking to convey. Cirrus’ LED systems responded to the demand for a single color LED display by introducing its revolutionary Grayscale Solo LED System. Solo was designed with small businesses in mind: a great looking, high quality, outdoor gray-scale LED display at an ultra-affordable price. After rigorous development, our engineers succeeded in producing lower cost panels without sacrificing any of Cirrus systems’ quality. Not only that, our grayscale Solo LED system is also less expensive than text-only, run-of-the-mill LED signs. We will also price match against any domestic competitor with a comparable product. Solo has the same features and capabilities all other Cirrus systems are known for: Modular technology, green design, accessible from the LED cloud software and 24 hour lead time; It plays video, images, and text at a medium resolution of 15 millimeter pixel pitch.
