Abstract: A display device and a flexible OLED panel. The flexible OLED panel includes: a flexible substrate, and OLED light emitting elements on the substrate. The OLED light emitting elements include pixel circuits and functional layers including anodes disposed above the pixel circuits. The flexible OLED panel further includes pixel unit regions and non-pixel unit regions. The pixel unit regions are arranged in an array, the non-pixel unit regions are disposed between adjacent pixel unit regions. At least one of the anodes, and corresponding transistors in the pixel circuits are located in one pixel unit region, respective transistors in the adjacent pixel unit regions are connected via electrical connection lines, so that the electrical connection lines pass through at least one non-pixel unit region, and a portion of the electrical connection lines in the at least one non-pixel unit region is coated by an organic film layer.

Abstract: A mask includes a mask body and at least one sub-mask provided on the mask body. The sub-mask includes an evaporation zone and a shield portion. The shield portion is provided with at least one groove in a thickness direction of the sub-mask. The groove has a depth smaller than a thickness of the mask body. Since the shield portion is provided with the groove, and a single groove has a depth smaller than the thickness of the mask body, it not only ensures that there is no pixel evaporated onto a substrate at the shield portion, but also reduces the thickness of the shield portion, thereby reduces weight thereof, lowers the weight difference between the shield portion and the evaporation zone and reduces the stress concentration on the shield portion, resulting in that the mask body is evenly stressed during tensioning.

Abstract: The present disclosure relates to a mask and a mask assembly. The mask includes a mask body and at least one sub-mask disposed on the mask body. The sub-mask includes an evaporation area and a shielding portion. The evaporation area is provided with a first evaporation hole penetrating the sub-mask in a thickness direction of the sub-mask. The shielding portion includes an isolation area and a dummy area, the dummy area corresponds to an irregular-shaped area of a display screen, and the isolation area is located between the dummy area and the evaporation area. The dummy area is provided with a second evaporation hole penetrating the sub-mask in the thickness direction of the sub-mask, and/or the dummy area is provided with at least one first groove, a depth of the first groove is less than a thickness of the sub-mask.

Abstract: A pixel arrangement structure, a display panel and a display device are provided in the present application. The pixel arrangement structure includes a plurality of pixel groups, each pixel group includes a first color light sub-pixel, a plurality of second color light sub-pixels and a plurality of third color light sub-pixels. The plurality of second color light sub-pixels and the plurality of third color light sub-pixels are alternately arranged around the first color light sub-pixel. Two adjacent pixel groups share a second color light sub-pixel and a third color light sub-pixel located between the two adjacent pixel groups.
