The electrode substrate layer 303 is specifically a substrate for integrating electrode blocks. The substrate may be transparent glass or transparent plastic, and in the specific implementation process, a person skilled in the art may set the substrate according to actual situations.
In order to reduce the stress of the driving circuit 301 when the OLED display panel is bent, in the embodiment of the present application, the electrode layer 302 is formed by N electrode blocks, and a gap is formed between every two of the N electrode blocks, where N is an integer greater than or equal to 2, as shown in fig. 2.

As shown in fig. 2, each electrode block includes a small buffer block under the electrode block, the interval between the buffer blocks is determined by the interval between the electrode blocks, and the area of each buffer block is slightly smaller than the area of the corresponding electrode block, so as to ensure that the adjacent electrode blocks are communicated. For example, if the electrode block is a rectangular parallelepiped of 5 × 3, the buffer block may be a cube of 4 × 2 or 3 × 3. The viscosity coefficient of the buffer layer 304 is greater than a preset value so as to bond the N electrode blocks and the electrode substrate layer 303, and specifically, the buffer layer 304 may be formed by an optical adhesive or a pressure-sensitive adhesive, or may be formed by other adhesives with low young's modulus, low flexibility, and moderate thickness of the buffer layer 304.
