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 12):
The backlight module according to  claim 1  further comprising:\n a set of half transmitting and half reflective films provided between the first region and the second region and comprising M half transmitting and half reflective films, each of the half transmitting and half reflective films makes a predetermined angle with the second sidewall of the light guide plate, \n wherein a m\u22121th half transmitting and half reflective film has a first surface configured to transmit part of the light rays coming from the first region to the second region and to reflect another part of the light rays to a mth half transmitting and half reflective film, a second surface configured to transmit part of the light rays reflected from a m\u22122th half transmitting and half reflective film to the mth half transmitting and half reflective film and to reflect another part of the light rays reflected from the m\u22122th half transmitting and half reflective film to the second region, wherein 1<m\u2264M, m and M are integers.
