Problems solved by technology

At present, organic light-emitting display panels adopt on-cell touch technology. When using on-cell touch technology to manufacture organic light-emitting display panels, it is necessary to fabricate touch structures outside the organic light-emitting display panel, and the process is relatively complicated. , the production cost is relatively high; since the touch structure is fabricated on the outside of the organic light emitting display panel, the overall thickness of the organic light emitting display panel formed is relatively thick
[0004] In addition, for flexible displays, the thickness of the panel is very important, which determines whether it is conducive to bending. However, the organic light-emitting display panel formed by using the on-cell touch technology in the prior art is relatively thick, which is not conducive to bending.
