Flexible screen protection structure and method for manufacturing the same, and flexible display screen using the same
A flexible screen protection structure includes a first flexible plate, a second flexible plate opposite to the first flexible plate, a side plate, a number of first trapezoidal bosses, and a number of second trapezoidal bosses. A gap is formed between the first flexible plate and the second flexible plate. The side plate surrounds peripheral sides of the first flexible plate and the second flexible plate, and closes the gap. The first trapezoidal bosses are densely distributed on the first flexible plate and located in the gap. Each first trapezoidal boss includes a large end attached to the first flexible plate and a small end facing the second flexible plate. The second trapezoidal bosses are densely distributed on the second flexible plate and located in the gap. Each second trapezoidal boss includes a large end attached to the second flexible plate and a small end facing the first flexible plate.
