Display panel, display module, and display device

A display module, comprising:

• a data drive circuit and a display panel;
• wherein
• the display panel includes:
• a base substrate, comprising a first display region and a second display region at least partially surrounding the first display region;
• a drive circuit layer on a side of the base substrate, wherein the drive circuit layer comprises a plurality of first pixel circuits and a plurality of second pixel circuits that are disposed in the second display region;
• and
• a first electrode layer, at least comprising a plurality of first-type electrode patterns, wherein the plurality of first-type electrode patterns comprise a plurality of first electrode patterns in the first display region and a plurality of second electrode patterns in the second display region;
• wherein at least two of the plurality of first electrode patterns are connected to one of the plurality of first pixel circuits, and at least two of the plurality of second electrode patterns are connected to one of the plurality of second pixel circuits;
• and
• the data drive circuit is connected to first data lines, third data lines, fourth data lines, and seventh data lines that are in the display panel.
