Display panel preparation method and display panel

The invention provides a display panel preparation method and a display panel. The preparation method of the display panel comprises the following steps: preparing a plurality of light-emitting chips with magnetic layers; forming a groove on a back plate; an electromagnetic device is installed on the surface, back to the groove, of the back plate; causing the electromagnetic device to generate the same magnetic pole as the magnetic layer in the second sub-pixel; transferring a part of the light emitting chip into the groove in the first sub-pixel; turning off the electromagnetic device, and transferring a part of the light-emitting chip into the rest of the groove; and separating the back plate from the electromagnetic device. According to the invention, through cooperation between the magnetic layer and the electromagnetic device, a recyclable, low-cost, high-precision and high-yield chip transfer project is realized. 本发明提供了一种显示面板制备方法及显示面板。所述显示面板制备方法包括以下步骤：制备若干带有磁性层的发光芯片；在一背板上形成一凹槽；在所述背板的背对所述凹槽的一表面上安装电磁装置；使所
