Abstract
A light guide assembly includes a light guide plate and a light guide strip around the periphery of the light guide plate, where a plurality of light-transmitting holes are formed on one side of the light guide strip facing to the light guide plate, and at least one end of the light guide strip is an light incident side. The light is incident to the inside of the light guide strip from the light incident side, and then is incident into the light guide plate from the light-transmitting holes on the side of the light guide strip, and thus becomes a surface light source.
