The display panel includes a first substrate, a second substrate, and a plurality of pixel units. Each pixel unit includes a heating element, a reflective layer, a resonant cavity, and a phase-change material layer sequentially disposed on the first substrate, and a liquid crystal cell. The display panel also includes first signal lines extending along a row direction, second signal lines extending along the column direction, and a driving circuit in correspondence to each pixel unit. The driving circuit includes a first driving module and a second driving module that are connected to a same first signal line and a same second signal line. The first driving module drives the heating element to control the state of the phase-change material layer, and the second driving module controls the deflection of liquid crystal molecules in the liquid crystal cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display panel and display device","description":"Display panel and display device are provided.
