Abstract: A display module includes a display panel with a plurality of bonding electrodes arranged at intervals along a selected side edge of a non-display surface and divided into two bonding electrode groups, a first flexible circuit board and a second flexible circuit board. For the first flexible circuit board, each first conductive contact piece in a first wiring region is connected to a bonding electrode in a first bonding electrode group. For the second flexible circuit board, each second conductive contact piece in a second wiring region is connected to a bonding electrode in a second bonding electrode group. The first wiring region is closer to the selected side edge than the second wiring region in a first direction. The first fan-out region is spaced apart from the second wiring region in a second direction perpendicular to the first direction.

Abstract: A display panel includes a plurality of sub-panels tiled in sequence along a first direction. The sub-panels have a first edge and a second edge in the first direction. The sub-panels include a column of first pixels closest to the first edge, a column of second pixels closest to the second edge, and a plurality of columns of third pixels between the column of first pixels and the column of second pixels. A sum of a distance between effective display bodies in the first pixels and the first edge and a distance between effective display bodies in the second pixels and the second edge is smaller than a spacing between effective display bodies in two adjacent columns of the third pixels.

Abstract: A backlight assembly includes a light guide plate, containing a plurality of dots. Each dot includes a first reflecting surface and a second reflecting surface, respectively configured to reflect a first incident light such that reflected light emerges in a first preset direction in a narrow viewing angle mode, and to diffusely reflect a second incident light such that the reflected light emerges dispersedly in a wide viewing angle mode. A first light source can be disposed over a lateral side of the light guide plate and facing the first reflecting surface, to provide the first incident light on the first reflecting surface in the narrow viewing angle mode. A second light source can be disposed over another lateral side of the light guide plate and facing the second reflecting surface to provide the second incident light on the second reflecting surface in the wide viewing angle mode.
