In direct sunlight or ambient light, the visible distance is several meters. As they are indoor, there is no need to open air, and the screen cannot have a sealed and waterproof function. Due to the low required display brightness indoors, the indoor display point matrix module is mainly used. The outdoor irregular screen has an area of several tens of square meters, ranging from several hundred square meters to several thousand square meters. The point density is relatively thin (over 1000-4000 points per square meter), and the luminous brightness is 3000-6000cd/square meter (with different directions and brightness requirements). Under direct sunlight, the visible distance is several tens of meters. As it is outdoor, a waterproof box must be used, which has a good wind, rain, and lightning resistant screen on top.
