    摘要: An exemplary backlight module (11) includes a first light guide plate (15), and a second light guide plate (17). The first light guide plate includes a first bottom surface (156), and plural reflective micro-structures (158) formed at the first bottom surface. The second light guide plate is located adjacent the first bottom surface of the first light guide plate. The second light guide plate includes a second bottom surface (176), and plural diffusing micro-structures (178) formed at the second bottom surface.

    摘要: An exemplary backlight module (1) includes a reflective polarizer sheet (10), a diffusing sheet (11), and a reflective sheet (14). The reflective polarizer sheet includes a light incident surface (102), a light emitting surface (104) opposite to the light incident surface, and a plurality of prism structures (106) at the light emitting surface. The diffusing sheet is adjacent to the light incident surface of the reflective polarizer sheet. The reflective sheet is below the diffusing sheet. The backlight module has a high brightness and an improved light utilization ratio with a low cost and a reduced thickness.

    摘要: A light guide plate (200) includes at least one surface through which light beams pass, at least one translucent ink film (220) disposed on the at least one surface through which light beams pass, and the at least one translucent ink film includes a plurality of pigment particles (221). The pigment particles of the translucent ink film can absorb red light and green light, and thereby compensate for a shift in chromaticity that would otherwise occur in a backlight module due to absorption of blue light in the optical sheets of the backlight module. Therefore degradation of the display quality of the LCD is reduced or even eliminated.
