Abstract
An OLED display panel and a mobile phone are disclosed. The OLED display panel includes a transparent display region and an effective display region that surrounds the transparent display region and completely covering an OLED display panel. The transparent display region is used for installing an electric device in front of the mobile phone and disposed below the transparent display region, which can achieve a high screen occupation ratio to give users a better visual experience. Additional and patterned OLED anode layer and the OLED light-emitting layer are arranged in the effective display region comparing to the transparent display region, except for the OLED anode layer and the OLED light-emitting layer, the effective display region and the transparent display region are provided with same film layers, and the same film layers is finished in a same manufacturing process, which can avoid an irregular-shape cutting, simplify production process and reduce cost.
