Device for bending sheet, LED module and display screen

A device for bending a sheet which comprises a first outside surface and a second outside surface opposite to the first outside surface, comprising:

• at least two abutting members fixed to at least two first portions of the first outside surface of the sheet or fixed to at least two second portions of the second outside surface of the sheet;
• an angle formed between the at least two abutting members;
• wherein
• the at least two abutting members are moveable relative to each other such that the angle is adjustable between a desired range, and the at least two first portions or the at least two second portions are bent according to the angle,
• wherein the at least two abutting members comprise a first abutting member and a second abutting member;
• the first abutting member is fixedly connected to the second outside surface of the sheet, the second abutting member is fixedly connected to the second outside surface of the sheet, and the second abutting member is rotatably connected to the first abutting member;
• and
• wherein a rotating position and a locking position are provided at a connection of 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 so as to obtain a desired curvature of the sheet.
