1. At the closing ceremony of the PyeongChang Winter Olympics, the "Beijing Eight Minutes" colorful cultural performance, Yipin Optoelectronics amazed the world with its transparent LED screen. For the Yipin Optoelectronics project, according to the requirements of the director team, the size of a single screen reaches a span of 1.5 meters, and the two screens are 3 meters long. If there is no pillar in the middle, it is difficult to stabilize. Faced with this difficult technical challenge, the Yipin R&D team has developed a 3-meter-long screen without vertical beams after repeated innovations and technological breakthroughs.

2. In order to ensure that the screen can withstand wind and freeze, all screens have been tested in wind tunnels and cold storages, reaching the requirement of wind speed of 15 meters per second. In order to achieve a certain stability of Yipin Optoelectronics LED transparent screen, it is necessary to do a good job of the card slot behind it. The structure is very precise, and the distance quotient between the card slot and the screen can be calculated in microns. The technical requirements put forward by the "Beijing Eight Minutes" performance also promoted the innovation of this display screen technology.
