背光模組

Abstract

一種背光模組，其包括導光模組、多個第一以及第二光源。導光模組包括第一、第二導光板以及多個第一、第二微結構。第一導光板具有第一底面。第一微結構由第一底面向外突出。第二導光板具有第二底面、第二頂面以及連接面。第二微結構由第二頂面向外突出。第二導光板包括多個聚光部。各聚光部具有入光面以及與連接面連接的出光面，且出光面的寬度大於入光面的寬度。第一光源位於入光面旁。第二光源位於連接面旁。 A back-light module including a light-guide module, first and second light sources is provided. The light-guide module includes a first and a second light-guide plates and first and second microstructures. The first light-guide plate has a first bottom surface. The first microstructures protrude outwardly from the first bottom surface. The second light-guide plate has a second bottom surface, a second top surface and a connecting surface. The second microstructures protrude outwardly from the second top surface. The second light-guide plate includes light converging portions. Each light converging portion has a light receiving surface and a light emitting surface connected to the connecting surface, and a width of the light emitting surface is larger than a width of the light receiving surface. The first light sources are located next to the light receiving surfaces. The second light sources are located next to the connecting surface.
