Display device and backlight module thereof

摘要

A display device and a backlight module are provided in the present invention. The display device includes the backlight module and a liquid crystal display panel. The backlight module, which is used to provide a backlight source for the liquid crystal display panel, includes a luminant device and a micro-lens array. The luminant device is disposed under the liquid crystal display panel, and the luminant device has a plurality of first luminant regions and a plurality of second luminant regions. The micro-lens array is disposed between the luminant device and the liquid crystal display panel. The micro-lens array includes a plurality of micro-lenses, and each of the micro-lenses overlaps at least one first luminant region and at least one second luminant region in a direction perpendicular to the liquid crystal display panel.

1. A backlight module, which is used to provide a backlight source for a liquid crystal display panel, the backlight module comprising:
a luminant device, disposed under the liquid crystal display panel, the luminant device comprising a plurality of first luminant regions and a plurality of second luminant regions, wherein each of the first luminant regions and each of the second luminant regions are disposed alternately along a first direction; and a micro-lens array, disposed between the luminant device and the liquid crystal display panel, wherein the micro-lens array comprises a plurality of micro-lenses, and each of the micro-lenses overlaps at least one first luminant region and at least one second luminant region in a direction perpendicular to the liquid crystal display panel; wherein each of the first luminant regions provides light in a first display direction via a partial area of the corresponding micro-lens, and each of the second luminant regions provides light in a second display direction via a partial area of the corresponding micro-lens, wherein under a first stereoscopic display mode, a timing of providing light along the first display direction from the first luminant regions is separated from a timing of providing light along the second display direction from the second luminant regions.
