    Abstract: Provided is a display module, including a base substrate, a plurality of light-emitting patterns, and a plurality of microlens groups corresponding to the light-emitting patterns. An orthographic projection region of at least one of the light-emitting patterns on the base substrate forms a primary display region. The plurality of microlens groups are disposed on a side, distal from the base substrate, of the plurality of light-emitting patterns. An orthographic projection of the microlens group on the base substrate is within the primary display region formed by the corresponding light-emitting pattern. The microlens group includes at least two microlens structures, and a gap is defined between any adjacent two microlens structures. The light-emitting pattern includes a target region. An orthographic projection of the target region on the base substrate is overlapped with an orthographic projection of the gap on the base substrate. The target region does not emit light.

    Abstract: A photoelectric detection substrate, a method for fabricating the same, and a photoelectric detection device are disclosed. The photoelectric detection substrate includes a thin film transistor and a photodiode coplanar with the thin film transistor. The thin film transistor has a vertical channel structure and includes a gate electrode, an active layer, a first electrode and a second electrode. The photodiode includes a first doped layer, an absorption layer and a second doped layer disposed in this order. The active layer and the absorption layer are disposed in a same layer and formed by a same patterning process. By forming a photodiode coplanar with a thin film transistor of a vertical channel structure, the overall thickness of the photoelectric detection substrate is effectively reduced, deformation of the substrate caused by stress is reduced, and damage caused by deformation of the substrate is avoided, and thereby the yield is improved.
