In recent years, with the development of small-pitch LED display technology, the picture quality of LED displays has become more and more high-definition and fine, and the problem of low brightness and high gray has been overcome. This has broken the law that LED display can only be used in the outdoor field. Therefore, LED display screens have also been continuously used in the field of indoor engineering display, including subway advertising.
Take indoor subway advertising as an example. It has the characteristics of concentrated flow of people and a high degree of attention, which can increase consumers' awareness of the product. Compared with traditional outdoor advertising, subway advertising LED displays are closer to consumers and attract more attention. So what are the common LED displays in subway stations?
1. Light box LED screen in track area
It is suitable for the advertising display of subway tracks, and the main audience is waiting passengers. The light box screen in the track area requires the product to have a high pixel density, can be installed before maintenance, undergo EMC treatment, and have protection capabilities such as moisture, water, corrosion, and shock resistance.
2. Platform advertising LED screen
It is suitable for the advertising display on the subway booth level. The advertising screens on the platforms have relatively close viewing distances and interact with consumers through QR codes and somatosensory technology. Therefore, parameters such as contrast, refresh rate, and grayscale are required to be relatively high.
3. Advertisement LED screen in the station hall
It is suitable for the advertisement display in the subway entrance hall. The product is usually wall-mounted and requires a wide viewing angle to meet the needs of consumers for viewing at close range and a wide range.
The urban standard configuration of modern subways lies in complete hardware facilities and population size. By adding human body sensing devices, subway advertising displays can even change from one-way communication to two-way interactive communication between consumers and large LED screen.
