We sometimes see a type of transparent LED display on shopping malls or building facades. How does it manage to show image content on the front like a normal screen, while the back looks transparent like glass? The key to this technology lies in its special physical structure. Here we take Milestrong's STJ series as an example.
The STJ series transparent LED display consists of tiny circuits and LED beads encapsulated in a transparent soft module (or you can think of it as a flexible acrylic panel). The LED beads emit light on only one side-the front side-while the back side does not emit light. With this transparent soft module, looking from the front, the illuminated LED beads produce the displayed images; looking from the back, these tiny beads do not interfere with the normal transparent view. Thanks to this high light transmittance, the transparent LED display can function as a screen without blocking the line of sight.
Currently, this type of transparent LED display is becoming increasingly common in shopping malls and stores, because such screens convey a high-tech feel and provide a visually sci-fi experience. As a result, they can better capture the attention of passersby.
