Abstract: A device for bending sheets includes a first abutting member and a second abutting member fixedly connected to an outside surface of the sheet. The second abutting member is rotatably connected to the first abutting member. A rotating position and a locking position are provided at the connection between the first abutting member and the second abutting member. The first abutting member and the second abutting member are capable of rotating relative to each other at the rotating position, and the first abutting member and the second abutting member are capable of being interlocked with each other at the locking position. The first abutting member and the second abutting member are interlocked so as to obtain a desired curvature of the sheet. The present invention further provides an LED module and a display screen.
