The transformation and improvement of Haixin Sand Sail Screen replaced the eight-sided sail screen installed on the 87-meter-high mast from the original 100*25mm pitch with Leyard Smart Display’s 31.25*31.25mm small-pitch folding LED screen. The overall total resolution is increased by more than 2.5 times, which can achieve 4K high-definition display effect. While ensuring a high-brightness display effect, it achieves high transparency and greatly improves maintenance efficiency. The upgraded Haixinsha has 4 seats and 8 foldable liftable sail screens, making a shocking debut, adding another eye-catching city card to Guangzhou.
