Taking indoor subway advertisements as an example, it has the characteristics of concentrated traffic and high attention, which can increase consumers' awareness of products. 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 screen in the track area: suitable for advertising display on the subway track, the main audience is waiting passengers. The light box screen in the track area requires products with high pixel density, which can be installed before maintenance, EMC treatment, and have protection capabilities such as moisture-proof, waterproof, anti-corrosion, and shock-proof.

2. Platform advertising screen: suitable for advertising display on the subway booth floor. Due to the short viewing distance and interaction with consumers through QR code and somatosensory technology, platform advertising screens have higher requirements for display parameters such as contrast, refresh rate, and grayscale.

3. Advertising screen in the entrance hall: suitable for advertisement display in the entrance hall of the subway. This product is usually wall-mounted and requires a wide viewing angle to meet consumers' close-range and wide-ranging viewing needs.

The urban standard of modern subways lies in complete hardware facilities and population size. By adding human sensing devices, subway advertising displays can even change from one-way communication to two-way interactive communication between consumers and large LED screens.
