The LED display with asymmetrical direct insertion device can save more than 30% compared with the traditional direct insertion LED display, which significantly reduces the operation cost of the advertising operator. At the same time, it has a better viewing effect than the traditional LED display device, which has the advantage of significant reduction in light pollution.
