Abstract:
1. An edge-light backlight assembly, comprising: a light guide, made of a light-pervious material, and comprising a primarily reflecting surface, a light exiting surface, and a light entering interface, wherein the light guide is arranged such that the primarily reflecting surface is disposed opposite the light exiting surface, and the light entering interface connects the primarily reflecting surface and the light exiting surface; and a protruding part, made of a light-pervious material, disposed on the light entering interface, and the protruding part comprising: a first light entering surface, disposed opposite the light entering interface, for receiving light to enter the protruding part, and the light entering the light guide through the light entering interface and being projected on the primarily reflecting surface; at least one secondary reflecting surface, located between the light exiting surface of the light guide and the first light entering surface, for reflecting the light such that the light enters the light guide through the light entering interface and is projected on the primarily reflecting surface; and at least one second light entering surface, located between the primarily reflecting surface of the light guide and the first light entering surface, and disposed opposite the secondary reflecting surface, for the light to pass through to enter the protruding part, so as to be projected on the secondary reflecting surface.
