A method for manufacturing a display panel, a display panel, and a transferring device are provided. Metal liquid is formed on a side surface of the base substrate to form a first region to be bonded. After curing, the second connecting lines are formed by etching such that the second connecting lines correspond to and connect to the first connecting lines disposed on the front surface of the base substrate, thereby providing the side bonding of the display panel. By using an integral transferring and etching method, the line width and pitch of the connecting lines in the region to be bonded can be reduced, which makes it suitable for full-size display panels with a wider range of applications, especially for products with high resolution.

A method of producing a flexible conductive film includes: producing a bottom film and applying a pre-stretched stress on the bottom film; forming a conductive layer on the pre-stretched bottom film; and releasing the pre-stretched stress applied to the bottom film wherein the bottom film and the conductive layer are elastically contracted; the conductive layer and one side of the bottom film adjacent to the conductive layer shrink in a wave shape.

A mask plate group of an organic light emitting diode (OLED) panel, a cathode evaporation method thereof and an OLED panel are provided. The OLED panel includes a display area having an imaging area, and the mask plate group includes a first mask plate and a second mask plate. The first mask plate includes a common mask opening area.

A display substrate and a mask plate assembly includes a base substrate, a pixel defining layer, a functional layer, a cathode layer, and a covering layer that are sequentially stacked in a direction away from the base substrate, wherein the size of orthographic projection of the functional layer on the base substrate is jointly determined by the size of a display area and a first minimum distance. The first minimum distance is the minimum distance in a direction from the display area to a non-display area and between the boundary of the display area and the boundary of the functional layer, and is determined by a first shadow width of the functional layer extending from the display area to the non-display area. The first shadow width is the maximum width of a shadow area formed within a preset region when the functional layer is vapor deposited in the preset region.
