New description: [New technical field] The present invention relates to a backlight module and a liquid crystal display device, and more particularly to a backlight module having a fixing unit and a liquid crystal display device. [Prior Art] With the advancement of display technology, liquid crystal display devices have been widely used in consumer electronic products such as notebook personal computers, personal computers (PCs), and televisions. Since the liquid crystal panel of the liquid crystal display device does not have the function of emitting light, a backlight module is disposed under the liquid crystal panel to provide a light source required for the liquid crystal panel, thereby enabling the liquid crystal panel to achieve the display purpose. In the conventional backlight module, a LED light bar is mostly used as a light source, and a light emitting diode light strip is disposed beside the light guide plate. However, when the distance between the light-emitting diode light strip and the light guide plate is too close, the position of the light-emitting diode on the secret light-emitting diode will produce a bright spot (H〇tsp〇t), resulting in uneven surface light source. . The heart is in the back of the money. The frame is pressed against the light guide plate. The light guide plate is not easily shaken in the direction of the light guide plate (2-axis direction). The material strength of the miscellaneous material is weak, so in the vibration test (4) plus the wrist occurs, the mine 1 has no material to solidify the green, which causes the relative displacement of the body light strip. On the other hand, the performance is also poor. It is also prone to deformation in the reliability test M415319. [New content] In view of this 'this_providing-age paper group, by means of (4) the fixed part can fix the guide, so that the back button group is not easy to cause the position of the light guide plate to be displaced under various conditions, and can provide a uniform surface. light source.

The material of the crucible may be selected from the group consisting of metal, ceramic and combinations thereof. Since the material strength is strong and the heat resistance is good, the fixing member 140 can effectively fix the light guide plate 120' and in the reliability test (or poor storage) Or in the environment of use) is not easy to deform. It is to be noted that the fixing member 140 can effectively fix the light source 130 between the bottom plate 112 and the fixing member 140 by the first bending portion 144 a, in addition to effectively fixing the light guide plate 120 in the z-axis direction. . In other words, the fixing member 140 can maintain the relative distance between the light source 130 and the light guide plate 120 in the Z-axis direction and the horizontal direction, thereby preventing the occurrence of a bright spot problem. Furthermore, even after the backlight module 100 receives the vibration test or after the conveyance test, the problem that the optical display is abnormal due to the relative positional deviation between the light guide plate 120 and the light source 130 is less likely to occur. The backlight module 100 may further include a reflective sheet 180 disposed between the light guide plate 120 and the bottom plate 112. The reflective sheet 180 can reflect the light emitted by the light source 130 more efficiently into the light guide plate 120, thereby improving the light utilization efficiency of the backlight module 100. Furthermore, the backlight module 1 can further include an optical film set 190, and the optical M415319 film set 190a is placed between the light guide plate 120 and the plastic frame 150. The optical film set 190 includes a diffuser (Diffuser), a brightness enhancement film (BEF), a polarized transfer film (DBEF), and combinations thereof. Those skilled in the art will be able to match different light guide plates 120 and optical film sets 190 as needed to achieve the desired optical effect. Furthermore, the backlight module 1 上述 adopts a lampless cover design, which can save the space occupied by the lamp cover (not shown) in the component accommodating space R, and can increase the adjustment of the distance between the light guide plate 120 and the light source 130. The tolerance can increase the ratio (A/p) of the distance (a) between the light incident surface 120a of the light guide plate 120 and the light source 130 and the distance (P) between the plurality of light sources 130, and can avoid 1^ point. problem. Moreover, the backlight module 100 does not need to use a lamp cover, which can save material cost of the lamp cover and has a simple structure. In view of the above, the backlight module 100 described above can provide a uniform surface light source. Referring to FIG. 2 again, in the liquid crystal display device 1A, the liquid crystal display panel 200 can be disposed on the plastic frame 15A. Further, the liquid crystal display device 1A may further include a front frame 300, and the front frame 3'' is disposed on the liquid crystal display panel 2''. The frame 300 and the frame 150 of the backlight module 100 sandwich the liquid crystal display panel 200. Since the liquid crystal display panel 200 has the above-described backlight module 100 capable of providing a uniform surface light source, the liquid crystal display device 1000 can provide a good quality image. In summary, the backlight module and the liquid crystal display device of the present invention have at least the following advantages: The movement of the light guide plate in the Z-axis direction (the normal direction of the light guide plate) can be effectively restricted by the fixing member. In this way, when the backlight module receives the vibration measurement 11 M415319 2 or after being transported, the problem of the position offset of the guide button is less likely to occur. Since the material of the solid & material is strong and heat resistant, it can effectively hold the light guide plate and is not easily deformed in the reliability test (or bad or use ring =). In addition to the guide plate in the direction of the x-axis, the inferior part of the material is effectively fixed between the plate and the IS member. In this backlight module without a lamp cover design, the distance between the light source and the guide is kept at a desired distance to prevent the occurrence of bright spots. = However, this creation has been disclosed above by way of example, but it is not intended to limit the general knowledge in the technical field of tit 3, and it does not deviate from: and Fan _, # can make some changes and retouching, so this is a dull The scope is subject to the definition of the scope of the patent application attached.
