In busy areas like subway stations, display technology is needed for navigation, advertising, emergency messages, and schedules. With the continuous flow of traffic, water and dust exposure, and the requirement for unobstructed visibility from multiple directions, choosing the ideal display system becomes paramount. COB LED display technology is emerging as one of the most effective and dependable choices for subway stations, outperforming traditional SMD displays.

COB LED displays are stronger and more durable against external conditions. COB's special packaging encapsulates the LED chips on the PCB board directly and subsequently isolates them with epoxy resin, forming a smooth and solid surface. This type shields the display from dust, water, and mechanical pressure, which dominate in the subway environment. The screen display is also smooth and anti-collision, and therefore COB displays are an excellent choice for areas where the passengers will be close to the screen.

Another prominent advantage of COB technology is its superior visual performance. Subway stations are typically subjected to mixed lighting, and COB LEDs support high contrast, wide viewing angles, and reduced glare, with uniform visibility in high or low light levels. The ability to offer narrow pixel pitch via COB displays also allows for the presentation of high-definition content, which is especially beneficial for the presentation of timetables, real-time messages, and dynamic ads.

Another reason why subway operators would seek to utilize COB LED displays is because they conserve energy. COB LED displays consume less power than other conventional solutions and, hence, provide cost savings on running costs in the long run — a matter of paramount importance in mass-scale public transportation systems.
