Display module, preparation method thereof, and electronic device

A preparation method of a display module, comprising steps of:

• preparing a flexible driving substrate on a glass substrate;
• moving a miniature light-emitting diode chip to the flexible driving substrate and perform an encapsulation to obtain a display panel, wherein the miniature light-emitting diode chip includes a plurality of miniature light-emitting diodes;
• bonding a flip-chip film in a binding area of the display panel;
• providing a flexible protective film on the display panel;
• removing the glass substrate under the flexible driving substrate;
• attaching the support body to a side of the display panel located in a display area away from the miniature light-emitting diode chip, wherein a shape of a longitudinal section of the support body is rounded rectangle;
• and
• bending a bending area of the display panel and attaching the display panel to the support body.

An electronic device, comprising:

• at least two display modules, wherein the display module includes:
• a support body;
• and
• a display panel, wherein a cross-sectional structure of the display panel includes:
• a bending flexible driving substrate including a display area, a bending area, and a binding area, wherein the bending flexible driving substrate has a cavity;
• and
• a display unit bound to the display area, wherein the display unit includes a plurality of miniature light-emitting diodes;
• wherein the support body is provided in the cavity, and a shape of a longitudinal section of the support body is rounded rectangle.
