One road hazard that has not received a lot of attention is that of large vehicles, such as buses, which can obstruct other drivers’ line of sight, leading to road accidents. But now, a team from Ming Chi University of Technology in Taiwan, has developed a potential solution. They have designed a display screen for large vehicles that can alert cars to oncoming traffic. The AVED barrier screen is an organic light-emitting diode display (OLED) that can be hung on the outside of buses or other large vehicles. It is paired with a camera and wide-angle lens that is mounted on the front of the vehicle. The camera captures what is happening in front of the vehicle and projects these images onto the screen. This allows other vehicles to see oncoming traffic. The AVED can also double as an AR advertising screen. The designers suggest that this could be used to provide information for tourists, a view of the shops normally blocked by large vehicles, and interactive ads.
