Abstract: A display module includes a display device, a pivot member, and a reflection-mirror device. The display device includes a light splitting device and a monitor for displaying first and second images arranged alternately. The light splitting device is disposed at a position corresponding to a light exit side of the monitor for splitting the first and second images along first and second splitting directions respectively. The pivot member is disposed at a side of the display device. The reflection-mirror device is connected to the pivot member to be foldably pivoted to the side of the display device. The reflection-mirror device is for reflecting the first images split along the first splitting direction in a reflection direction when being unfolded relative to the display device. The reflection direction is relatively biased toward the monitor so as to form an included angle cooperatively with a normal of the monitor.
