With more than 500 cities around the globe moving toward the goal of becoming smart cities in the near future, demand for related display productions and solutions is expected to grow year by year, according to Digitimes Research.
While the deployments of these public information display (PID) products may differ from city to city, a number of aspects such as traffic control, security surveillance, environmental monitoring, retail marketing and e-administration are likely to be given priority for the set-ups of PIDs.
Riding high on the smart city movement and significant drops in panel prices over the year, global demand for PIDs in 32-inch and above sizes are expected to reach 7.3 million units in 2021, an increase of 61% from the amount seen in 2017, Digitimes Research estimates.
Indoor PID applications are seen broadly at airports, MRT systems, large-scale retail stores, convenience stores, department stores, and exhibition halls.
Outdoor applications must consider factors such as rain, humidity, scratches, collision and air pollution, as well as competition from LED display products, so the number of outdoor applications are less than those for indoor ones, but the unit prices of outdoor PIDs are much higher.
In recent years, more large-scale cities have been promoting the application of outdoor PIDs. The LinkNYC projec will see New York City transform its 7,500 traditional telephone booths into kiosks with Wi-Fi connection, which will call for the use of 15,000 55-inch LCD panels. Capital required for the project is to be fully self-sufficient via advertisement incomes to be generated from the digital signage boards fitted on the kiosks. Such project has also been adopted by other cities such as Philadelphia and London.
