Abstract: A light guide plate has a light incident surface having an arc configuration and also includes upper and lower surfaces that are respectively provided with a first slope surface and a second slope surface, so that light passes through and is converged by the arc light incident surface and is subjected to total internal reflection at the first and second slope surfaces to have the light guided into the light guide plate and then projecting out through a light exit surface. The light guide plate demonstrates an excellent effect of convergence for light of all angles, so that the light guide plate can be structured thinner without deteriorating light coupling efficiency. Also provided is a backlight module, which involves the light guide plate.

Abstract: A backlight module and a plastic frame structure thereof are provided. The plastic frame structure mainly comprises a plastic frame body and a light source carrier. The plastic frame body is used to carry optical films such as a light guide plate, and the light source carrier is used to fix light sources. The two parts, i.e. the plastic frame body and the light source carrier, are connected with each other by a detachable means, so as to be conveniently tested respectively, and then assembled together when no defect is found, as so to increase the assembling efficiency. Furthermore, if the two parts are assembled but have defects found, the two parts can conveniently be changed, respectively. Therefore, not only the rework cost can be reduced, but also the efficiencies of the test and assembly for the whole of the backlight module are increased.
