Abstract
Provided are a display panel, a driving method thereof and a display device. The display panel includes a substrate, a pixel unit layer and an electrochromic layer. The pixel unit layer includes multiple pixel units arranged in an array and each pixel unit includes a main pixel region and a sub-pixel region. Along a direction facing away from the substrate, the main pixel region includes a first electrode, an organic light-emitting layer and a second electrode, and the sub-pixel region includes a third electrode and a fourth electrode. The first electrode is disposed in the same layer as the third electrode, the second electrode is disposed in the same layer as the fourth electrode, and the main pixel region is insulated from the sub-pixel region. The electrochromic layer is disposed on one side of the pixel unit layer facing away from the substrate.
