Abstract: The embodiments of the invention disclose a scanning type backlight module and a display device. Since a laser light source with good collimation is applied, during a display time of a frame, with the modulation of the optical path regulator, the laser emitted from the laser light source performs a progressive scanning for a region corresponding to at least one row of pixel units in a light guide plate or a display panel. Therefore, the problem of dynamic picture ghosting can be solved effectively; moreover, since the progressive scanning for the entire light guide plate can be realized by changing the light propagation path of the laser emitted from the laser light source with the optical path regulator, the number of the laser light sources can be reduced and the production cost can be decreased.
