Abstract
The invention relates to a light guide plate and a backlight module. The light guide plate comprises a transparent base plate and a plurality of microstructures, wherein the transparent base plate is provided with an underside, a light exit face and a light incidence face, wherein the light exit face and the light incidence face are opposite and the light exit face is connected to first surface and a second surface opposite to the first surface; the plurality of microstructures are separated mutually and at least arranged on the first surface of the transparentbase plate; each microstructure comprises a first coating and a second coating; the first coating is formed on the first surface and contains adhesive material; and the second coating is formed on atleast the partial surface of the first coating and contains photodiffusion material. The light guide plate and the backlight module, disclosed in the invention, have good light-emitting uniformity.
Description
【Technical field】 [0001] The invention relates to a light guide plate and a backlight module with the light guide plate. 【Background technique】 [0002] figure 1 It is an exploded perspective view of a conventional backlight module 20 . Such as figure 1 As shown, the backlight module 20 has a back plate 21, and the back plate 21 is provided with a light guide plate 22, a reflection sheet 23, a light source 24 and a group of optical films. The optical films include, for example, a diffusion sheet 25, a brightness enhancement film 26 and so on. The diffusion sheet 25 is adjacent to the light emitting side of the light guide plate 22 , the reflective sheet 23 is adjacent to the bottom surface 22 a of the light guide plate 22 , and the light source 24 is adjacent to the light incident side of the light guide plate 22 . The light guide plate 22 is a light-transmitting substrate. The light guide plate 22 can guide the light beam emitted by the light source 24, so that the ligh...
