An organic light-emitting diode display panel includes a display area, a transparent area, and a wire exchange area. The display area is used for displaying an image; the transparent area is used for placing a device, and the wire exchange area is positioned at a wire connecting site between the display area and the transparent area, wherein a metal wire from the display area is electrically connected to a high light-transmissive metal wire through a via-hole at the wire exchange area, and the high light-transmissive metal wire extends to the transparent area.

High screen ratio organic light emitting diode display panel

The present disclosure discloses a display panel and a display device. The display panel includes an array substrate and a plurality of pixel units. In a first display area, a minimum distance between an edge of an anode of a second pixel unit and an edge of a corresponding light-emitting portion is greater than a minimum distance between an edge of an anode of a first pixel unit and an edge of a corresponding light-emitting portion. The display panel and the display device provided by the present disclosure prevents a problem that user experience is compromised by differences in brightness of the display panel at wide viewing angles.

Display panel and display device

An organic light-emitting diode display panel and a display device are provided in the present disclosure. The organic light-emitting diode display panel includes a general display region and a light-transmitting display region, wherein the light-transmitting display region corresponds to an under-screen camera placement region; the organic light-emitting diode display panel further includes an array unit and a light-emitting unit disposed on an upper side of the array unit, and the light-emitting unit includes a cathode layer disposed on a surface of the array unit. The cathode layer includes a second cathode portion corresponding to the light-transmitting display region, and a first cathode portion corresponding to the general display region, and the second cathode portion and the first cathode portion are disconnected from each other to connect different voltages respectively.

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.

The present invention provides a curved-flexible display device, which comprises a flexible display screen (), a storage housing (), and a limiting-fixing assembly (). The flexible display screen () comprises an arc bending area () at an end side of the flexible display screen (). The arc bending area () has a display and touch function as a human-computer interaction interface. The limiting-fixing assembly () comprises a first member () disposed on an outer surface of the storage housing (), and a second member () disposed at a back surface of the arc bending area () and cooperated with the first member (). The second member () has an arc shape and a curvature of the second member () is the same as a curvature of the arc bending area (). When the storage housing () is storing the curved flexible display screen (), the limiting-fixing assembly () adheres and fixes the arc bending area () to the outer surface of the storage housing (), the user interaction experience is improved, production cost is reduced, and the appearance is more beautiful.
