Title: BACKLIGHT MODULE AND DISPLAY DEVICE
Abstract:
A backlight module (200, 400, 600) and a display device (100, 300, 500). The backlight module (200, 400, 600) comprises a backplane (210, 410, 610), a light guide plate (220, 420), a first optical film (230, 430, 620), an adhesive piece (270, 280, 450, 640), a second optical film (240, 440, 630) and a light source (201). The light guide plate (220, 420) is disposed in the backplane (210, 410, 610). The first optical film (230, 430, 620) is disposed over the light guide plate (220, 420). The first optical film (230, 430, 620) has a long groove (231, 621). One part of the adhesive piece (270, 280, 450, 640) is disposed in the long groove (231, 621). The second optical film (240, 440, 630) is disposed over or under the first optical film (230, 430, 620), and one part of the second optical film (240, 440, 630) overlaps the location of the long groove (231, 621) of the first optical film (230, 430, 620), so as to adhere onto the adhesive piece (270, 280, 450, 640) in the long groove (231, 621). The light source (201) is disposed on the backplane (210, 410, 610), adjacent to a light incident surface of the light guide plate (220, 420).
