Abstract:
The disclosure relates to a backlight module and a display device. A backlight module, comprises a light guide plate; a light source disposed adjacent to a light entering side of the light guide plate; and a light converging element disposed between the light guide plate and the light source, and configured such that light, from the light source, incident on a surface of the light guide plate opposite to a light-exiting surface of the light guide plate to satisfy a total reflection condition at the surface.

Claim (Index 7):
The backlight module according to  claim 6 , wherein a maximum radius r of the hemispherical convex lens is calculated according to the following equation:\n d+r \u00b7(1\u2212cos \u03b8)= r \u00b7sin \u03b8/tan(\u03b1/2) Where, the light source is disposed on a symmetric axis of the hemispherical convex lens, and the hemispherical convex lens and the light guide plate have the same refractive index;\n d is a distance between the light source and a point on the hemispherical convex lens closest to the light source; \n \u03b8 is an angle between a normal of the hemispherical convex lens at an intersection of an edge light ray of the light emitted by the light source and a hemispherical surface of the hemispherical convex lens and the symmetric axis, and is calculated by the following equation:\n n 2  sin(\u03b1/2+\u03b8)= n 1  sin(90\u00b0\u00b7arcsin( n 3 /n 1 )+\u03b8); \n \n Where, n 1  is the refractive index of the light guide plate and the hemispherical convex lens; \n n 2  is a refractive index of ambient gas; \n n 3  is a refractive index of a medium in contact with a side of the light guide plate opposite to the light-exiting surface of the light guide plate; \n \u03b1 is a light-emitting angle of the light source.
