Digital Signage - Transparent LED Display Screen

The LED Digital Signage industry is driven by continuous innovation and a recently advance sector is transparent LED display screen technology. Traditional LED display screen mounts pixels onto solid boards, solid tiles and then mounts onto cabinets or frames, a transparent LED display instead mounts pixels right onto a thin, skeleton grid or flexible film. This framework is designed to allow viewers to see through the gaps in the grid to objects on the other side of the LED display, thereby visualizing the LED display itself effectively transparent. This transparent LED display screen technology would be suitable for glass windows of a retail façade because customers outside the store would be able to see both the digital content of the LED display screen and the products behind it, while customers inside the store still enjoy the ambient light entering through those windows. These LED display screens have made a hit at trade shows and consumers are excited about the potential to transform their windows into digital canvasses.

The first thing to look for when considering transparent LED display screen is of course their transparency. The degree of transparency of each display screen have some range but most transparent LED displays provide around 75% transparency. This seems pretty good, but remember that the framework of the display screen does not tint the window but rather physically obstructs it. Therefore, a transparent LED display screen is analogous to a window blind where a traditional LED display would resemble a blackout curtain. Window blinds are useful for letting in light but hardly anyone would consider them transparent, even when angled to allow the greatest degree of visibility. The skeleton frame of the display is not the only piece of hardware. Wires and mounting equipment, while smaller than traditional structures, are still present. If a display screen like this is installed onto a retail façade window, those outside will see the LED display screen but those inside will see the display, too. Instead of seeing the content on the pixels however, they’ll be seeing the rear of the display. Stores generally have windows so shoppers outside can see in and shoppers inside can see out; with a transparent LED display screen in the way, neither action is as easy as it should be.

In environments where high levels of ambient light are present, the brightness level of a display screen becomes paramount to its effectiveness. Transparent display screen, designed for windows and other glass panels, are designed for use in these high light settings. Most transparent LED display screen can shine between 1,000 and 1,500 nits which is a fine brightness level for interior spaces. However, when competing with the strength of sunlight, which reflects off shiny outdoor surfaces with around 2,200 nits, 1,000 nits is not going to get the job done. If a transparent LED display can’t even reach that brightness, what daytime usefulness will it really bring to a naturally lit environment? Transparent LED display screen are designed to showcase the scene behind them as well as their own content, but if the goal is to use the display to attract customers’ eyes to the products behind, the display needs to be noticeable in the first place.

The next consideration for LED display screen should be pixel pitch, the measure of how closely together adjacent LED units are aligned and a good barometer for digital image clarity. Combing through the various model lines of transparent LED display manufacturers, customers will find that the smallest pixel pitch any of them offer is slightly above 3mm. This is adequate for many purposes but that it represents the lower bound of transparent LED pixel pitch is a bit limiting to end customers with more ambitious goals. Spacing pixel pitch closer together is likely achievable for transparent LED display screen but doing so will compromise the transparency of the display.

Upon addressing each of these realities with transparent displays, customers have a fundamental question they should ask themselves: what do they want their LED Digital Signage to accomplish? If you want customers outside your store to see your products inside, a regular window does that job just fine. Similarly, if the ambient light flowing into your space through your window is valuable to you, or the ability to see outside is valuable to your customers, perhaps adding what amounts to digital blinds isn’t the best idea. Transparent LED display screen is a product that does the jobs of both a window and a display.
