1. An image display device with an ambient light strip assembly, comprising a light strip assembly and a back plate, wherein
the light strip assembly is mounted on the back plate and emits light to an outer side of the image display device;
the light strip assembly comprises a first light group, a second light group, a first corner light group, and a second corner light group;
along a direction perpendicular to a plate surface of the back plate, a projection of the first light group is adjacent to and arranged along a first edge of the back plate, a projection of the second light group is adjacent to and arranged along a second edge of the back plate, and the first edge intersects with the second edge;
the first corner light group and the second corner light group are located between the first light group and the second light group and are symmetrical about a straight line passing through a point of intersection of the first edge and the second edge; and
the first corner light group comprises more than two auxiliary light beads, an auxiliary light bead of the more than two auxiliary light beads is adjacent to the second corner light group, remaining auxiliary light beads of the more than two auxiliary light beads are arranged in sequence toward the first edge, a vertical distance between the auxiliary light bead adjacent to the second corner light group and the first edge is greater than a vertical distance between an auxiliary light bead of the more than two auxiliary light beads facing away from the second corner light group and the first edge, and an angle of inclination of light emitted by the auxiliary light bead adjacent to the second corner light group relative to the plate surface of the back plate is greater than an angle of inclination of light emitted by the auxiliary light bead facing away from the second corner light group relative to the plate surface of the back plate.
