The OLED panel has pixel units arranged in rows and columns, and each including an OLED device. The OLED panel includes regions arranged in column direction, and each including at least one row of pixel units and a cathode layer, the OLED devices in each region share the cathode layer therein, and the cathode layer of each region is disconnected from the cathode layer of any other region. The OLED panel includes a cathode voltage supply circuit configured to output a cathode voltage including an operating level to the cathode layer. The cathode voltage supply circuit is configured to start outputting the operating level to the cathode layer of at least one region at a time at least later than a time when all pixel units in the region receive a scan signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"OLED panel, driving method thereof and display device","description":"The present disclosure provides an OLED panel, a driving method thereof and a display device.
