The present disclosure provides a display panel, a driving method thereof, and a display device. The display panel includes: a first substrate; a second substrate, a light absorbing layer disposed on a surface of the first substrate facing the second substrate, a color film disposed on a surface of the second substrate facing the first substrate, a plurality of MEMS light valve units disposed between the light absorbing layer and the color film. The MEMS light valve unit includes a light shielding plate and a light reflecting layer disposed on a surface of the light shielding plate facing the color film. The plurality of MEMS light valve units is respectively located in a plurality of sub-pixel regions of the display panel, and an area of the light absorbing layer is smaller than an area of the color film in any one of the sub-pixel regions.
