Abstract
The present disclosure provides an array substrate and a preparation method thereof, a display panel and a driving method thereof, which belongs to the field of display technology. The array substrate includes a base substrate, a driving circuit layer, a reflective electrode layer, a light-emitting layer, an electrochromic layer, and a common electrode layer. The driving circuit layer is provided with a first and second driving circuit. The reflective electrode layer is provided on a side of the driving circuit layer away from the base substrate and provided with a first and second reflective electrode insulated from each other. The light-emitting layer includes a light-emitting unit arranged on the surface of the second reflective electrode away from the base substrate. The electrochromic layer is arranged on the surface of the first reflective electrode away from the base substrate. The common electrode layer covers the electrochromic layer and the light-emitting unit.
