What do you mean by “semi-outdoor”?
It’s hard to explain the difference in words. Regarding foldable, the whole Slim series can be called foldable, whereas, product series like Aqua, is named flexible because they are made of soft materials which show even greater “flexibility”. Strictly speaking, flexible＞foldable, introduction like “a foldable/flexible LED screen manufacturer” occurs because foldable LED screen is our flagship product. In addition, there are some physical limitations on foldable or flexible screens, for the foldable angle of the foldable LED screen please refer to the table in Q2. As for the “flexibility” of the flexible LED screen, let’s say “rolled diameter” , it shall be larger than 10~30 centimeters.
