Abstract

A lens an LED backlight module and a display device. The lens receives light rays emitted by a light source (8) through a light incident surface (9). After the light rays emitted by the light source enter the lens a part of the light rays (P1 P3) are directly refracted out from one light output surface and the other part of the light rays (P2 P4 P5) are first reflected to another light output surface or a bottom surface (10) through one light output surface then reflected to still another light output surface through the another light output surface or the bottom surface and finally refracted out from the still another light output surface. Accordingly the light rays emitted by the light source are scattered in the lens and then refracted out from different light output surfaces of the lens; therefore light output areas are enlarged and the light output uniformity is good. The lens is especially applicable to various LED backlight modules and display devices.
