Summary:The invention provides a display equipment backboard manufacturing method. The method comprises the following steps that a first corner part and a second corner part adjacent to each other in four corner parts contained in a display equipment backboard material sheet are cut according to a preset cutting mode to obtain a backboard main body containing a first cut-off edge and a second cut-off edge; a first region in the backboard main body is bent towards a direction close to a first surface of the backboard main body; and a second region in the bent first region is bent towards a direction close to the first surface, parts making contact with each other in the first cut-off edge are controlled to carry out an extrusion action, and parts making contact with each other in the second cut-offedge are controlled to carry out an extrusion action, so that a display equipment backboard comprising a C-shaped bent structure is obtained. Therefore, a corner extrusion forming process is used forreplacing a corner weldin
