[0002] The display back panel is an important component of the display. The back panel is usually made of metal and has the functions of enhancing the structural strength of the display, effectively dissipating heat and protecting internal electronic components. It is often necessary to punch holes in the display back panel during processing.

[0003] When punching holes in the display back panel, traditional display back panels are not provided with a fixed structure and are pressed manually.
