Display module and electronic device

An electronic device, comprising a display module;

• wherein the display module comprises a composite light-emitting layer, an electronic ink layer, and a cover plate layer disposed in sequence, wherein
• the electronic ink layer comprises a plurality of capsule bodies, and the plurality of capsule bodies are arranged along a plane on which the cover plate layer is located, wherein a first electrode and a second electrode are provided on a periphery of a capsule body, the first electrode is a transparent electrode and is disposed parallel to the cover plate layer, and the second electrode is disposed perpendicular to the cover plate layer;
• and ink particles are accommodated in the capsule body;
• when a voltage is applied to the first electrode, the ink particles are distributed along the first electrode and the display module is configured to perform displaying through the electronic ink layer;
• and
• when a voltage is applied to the second electrode and a voltage is applied to the composite light-emitting layer, the ink particles are distributed along the second electrode and the display module is configured to perform displaying through the composite light-emitting layer;
• wherein the capsule body is further provided with a third electrode on the periphery of the capsule body, a disposing direction of the third electrode intersects with the cover plate layer, and the third electrode is provided between the second electrode and the cover plate layer;
• when a voltage is applied to the second electrode, the ink particles are distributed along the second electrode to form a second light transmission gap;
• and
• when a voltage is applied to the third electrode, the ink particles are distributed along the third electrode to form a third light transmission gap, wherein
• the third light transmission gap is smaller than the second light transmission gap.
