The invention provides a preparation method of a touch display panel, the touch display panel and electronic equipment. The method comprises the steps that a display pixel layer is prepared on the surface of one side of a substrate; evaporating a first touch electrode layer on the surface of one side, far away from the substrate, of the display pixel layer; preparing a dielectric layer on the surface of one side, far away from the display pixel layer, of the first touch electrode layer; and preparing a second touch electrode layer on the surface of one side, far away from the first touch electrode layer, of the dielectric layer. The first touch electrode layer is prepared in an evaporation manner, so that the preparation process is simpler and more convenient, the step of preparing a bridging layer by utilizing an etching process is omitted, and the preparation cost related to etching is further reduced. 本公开提供了一种触控显示面板的制备方法、触控显示面板及电子设备，该方法包括：在基板一侧表面制备显示像素层；在显示像素层远离基板一侧表面蒸镀第一触控电极层；在第一触控电极层远离显示像素层一侧表面制备介质层；在介质层
