A display panel and a display device are provided. The display panel includes a display region, a perimeter region, and a hole region. The display panel further comprises an inorganic insulating layer, an organic insulating layer, an organic light emitting layer and a film packaging layer stacked. The organic light emitting layer is disposed correspondingly to the display region. At least one ring groove is defined in the inorganic insulating layer and/or the organic insulating layer corresponding to the perimeter region. A portion of the film packaging layer corresponding to the ring groove is closely contacted to the inorganic insulating layer and/or the organic insulating layer.

Display panel and display device

The present application provides a display panel and a display device. The display panel includes a display region, a peripheral region, and a light transmissive region. The peripheral region surrounds the light transmissive region, and the display region surrounds the peripheral region. The display panel includes an inorganic insulating layer, an organic insulating layer, and a thin film encapsulation layer stacked on each other. By forming a groove in the inorganic insulating layer in the peripheral region, the thin film encapsulation layer is in contact with the inorganic insulating layer through the groove, so that cracks are stopped from extending inwardly during cutting in the light transmissive region.

The present application provides a display panel and a display device. The display panel includes a substrate, a driving circuit layer disposed on the substrate, and a light-emitting layer disposed on the driving circuit layer. The driving circuit layer includes a first metal layer, the first metal layer includes a first metal trace, the light-emitting layer includes multiple light-emitting portions, and a vertical distance between an orthographic projection of a center of each light-emitting portion projected on the first metal layer and a symmetry axis of the first metal trace is less than or equal to 5 &#x3bc;m.

The present application discloses a flexible display panel and a method for manufacturing the same. By covering the edge of the metal film layer by using an organic protective layer at the groove of the planarization layer on the patterned metal film layer, which avoids subsequent etching of the anode etching solution of the organic light-emitting layer to the metal film layer, and prevents the metal at an edge of the metal film layer from being corroded, and can block moisture, oxygen and impurities in the air from entering a device area of the organic light-emitting layer along the edge of the metal film layer, thereby improving a packaging effect.

Flexible display panel and preparation method thereof

The present disclosure provides an organic light-emitting diode (OLED) display panel comprising a display area, a non-display, and a block area provided in the non-display area. The OLED display panel includes a signal trace layer, an organic film layer, and an anode layer which are sequentially located on the signal trace layer. The signal trace layer is provided with a signal trace in the non-display area. When an anode is formed on the anode layer, an anode material layer at least covering the exposed signal trace is formed in the corresponding block area, so as prevent mis-etching of the signal trace caused by the etching solution.
