Abstract:
A backlight module includes: a light guide plate; a light source for emitting light rays towards a first region of the light guide plate; a first grating provided at the first region and configured to adjust propagation directions of the light rays such that the adjusted light rays travel towards a second region of the light guide plate, and the propagation directions make an included angle with a normal to the light guide plate which is greater than the critical angle of total reflection of the light guide plate; and a second grating provided at the second region and configured to collimate the adjusted light rays such that the collimated light rays travel in a direction perpendicular to the light guide plate.

Claim (Index 4):
The backlight module according to  claim 1 , wherein the second grating comprises N second sub-gratings, a nth second sub-grating of the N second sub-gratings has a distance from the first region greater than that of a n\u22121th second sub-grating of the N second sub-gratings from the first region, wherein \u03b7 1 +\u03b7 2 + . . . +\u03b7 N =1, \u03b7 n \u00d7(1\u2212\u03b7 n-1 )=\u03b7 n-1 ,\n where 1<n\u2264N, n and N are integers, in is diffraction efficiency of the nth second sub-grating.
