Claim 0:
1. A display module, comprising: a first flexible circuit board, a display substrate, and a touch sensor on a display side of the display substrate,
wherein the display substrate comprises a flat region and curved surface regions respectively on two sides of the flat region in a first direction;
the touch sensor comprises a first bonding region and a second bonding region on a first side of a second direction intersecting with the first direction;
the first bonding region and the second bonding region are on a surface, away from the display substrate, of the touch sensor, and the first bonding region and the second bonding region are stacked with the flat region and are spaced apart from each other;
the first flexible circuit board is electrically connected with the touch sensor through the first bonding region and the second bonding region;
the first flexible circuit board comprises a main body, and a first bonding connection portion and a second bonding connection portion which protrude from the main body and are spaced apart from each other; and
the first bonding connection portion is extended to the first bonding region so as to be electrically connected with the first bonding region, and the second bonding connection portion is extended to the second bonding region in the second direction so as to be electrically connected with the second bonding region;
the first bonding connection portion and the second bonding connection portion of the first flexible circuit board are bent, and the main body of the first flexible circuit board is on a side, away from the touch sensor, of the display substrate;
the display module further comprising: a drive chip on the side, away from the touch sensor, of the display substrate,
wherein the drive chip is configured to drive the display substrate;
an orthographic projection of the drive chip on the flat region of the display substrate is in a region surrounded by an orthographic projection of the first bonding connection portion of the first flexible circuit board on the flat region of the display substrate, an orthographic projection of the second bonding connection portion of the first flexible circuit board on the flat region of the display substrate and an orthographic projection of the main body of the first flexible circuit board on the flat region of the display substrate; and
the orthographic projection of the drive chip on the flat region of the display substrate is spaced apart from the orthographic projection of the first bonding connection portion of the first flexible circuit board on the flat region of the display substrate, the orthographic projection of the second bonding connection portion of the first flexible circuit board on the flat region of the display substrate and the orthographic projection of the main body of the first flexible circuit board on the flat region of the display substrate.
