The embodiment of the invention provides a pixel structure, a preparation method thereof and a display panel. The pixel structure comprises at least two miniature light-emitting crystal grains arranged at one side of a substrate; a dimming layer which is arranged on one side of the substrate and one side of each miniature light-emitting crystal grain, and comprises comprises a first shading structure and dimming structures corresponding to the miniature light-emitting crystal grains, wherein each dimming structure comprises a first color conversion structure, and each dimming structure further comprises a second color conversion structure and/or a scattering structure; a filter layer which is arranged at the side, away from the substrate, of the dimming layer; and an electrode layer which is arranged at the side, away from the dimming layer, of the substrate and electrically connected with the miniature light-emitting crystal grains. According to the embodiment of the invention, the at least two miniature lig
