New Description: [New Technology Field] This creation relates to the structure of the light guide plate for improving the dark ripple of the backlight module, and aims to provide a light intensity that can be weakened by the light guide plate so that it is not totally reflected. The structure of the backlight module which reduces the phenomenon of dark and light ripples is improved. [Previous technology] - Press, generally applied to the liquid crystal display of the information device, can be selected according to the needs of the T-design, and the backlight is only τ or the edge-lit backlight = group structure; as shown in the figure The basic structure of the side-lit backlight module structure is mainly provided with a light source 2 2 in a lampshade i ,, and a plate end of a light guide plate 30 is sleeved at the open end of the lampshade 1 ' On the upper side of the light guide plate 30, a plurality of optical films 5 〇 and a liquid crystal panel 60 are sequentially disposed, so that the light of the light source 20 is incident on the light guide plate 3 from the plate end and is emitted toward the plate surface of the light guide plate 3 In order to achieve the effect of the liquid crystal panel 6 ; display; wherein each optical film 5 ◦ generally uses the lower diffusion. = 5 1 , the brightness enhancement sheet 5 2 and the upper diffusion sheet 5 i are sequentially disposed on the light guide plate = above ' The diffusion homogenization effect of the light source is increased by each optical film 5 Q . However, the general light-angle of the light guide plate is not ideal for the full vertical angle. The incident light does not reach the total reflection angle after the incident light, because the (four) light rays enter the light guide plate after entering the light guide anti-sub-reflection. Such a == often causes a bright band on the edge, so that the light guide plate has a ripple phenomenon, which affects the quality of the image display. 5 M295746 [New Content] With this in mind, this creation "improves the phenomenon that the backlight module has a dark corrugated 卩 ( ( 四 四 四 四 , , , , , , , , , , , , , , , , , / / / / / / / / / / The opening force is inserted and positioned on the fresh side, and the light guide plate includes at least a bottom surface intersecting the light incident surface and a surface opposite to the bottom surface; the bottom surface has a reflection sheet, and the light is guided by the light Light=into the first face into the person' to allow the light of the light source to be emitted toward the intended exiting side, wherein the light-emitting surface of the light guide plate and the bottom surface of the light-emitting surface and the bottom surface thereof are provided with a light-shielding element at the π end of the lamp cover. In order to weaken the intensity of light that is not totally reflected in the light guide plate, and to reduce the phenomenon of dark and bright ripples. [Embodiment] In order to enable the review committee to understand the structure of the creation and the operation mode of the whole body, the following is a description of the following: · A creation of a "light guide plate structure for improving the dark ripple of the backlight module", such as The second and third figures show that the basic structure of the one-side optical backlight module is not intended. It is also provided with a light source 2 in a lampshade 20, and a plate end of a light guide plate 30. The light guide plate 30 includes at least one light incident surface 3丄, a bottom surface 32 intersecting the light incident surface 3丄, and a light emitting surface 3 opposite to the bottom surface 32. 3. A reflective sheet 4 下方 is disposed under the bottom surface 3 2 , and a plurality of optical films 5 〇 and a liquid crystal panel 6 设有 are sequentially disposed above the light guide plate 3 to allow the light of the light source 2 to be incident from the plate end. The light guide plate 3 is projected toward the light guide plate 3 and the desired 6 M295746 plate surface to achieve the effect of the liquid crystal panel 60 display. Or in the light-emitting surface and the bottom surface of the two (two) light panels, in the example, the system =====with the shielding member' as shown in this figure
