New Description: [New Technology Field] This creation is about a flat panel display and backlight module, especially a flat display 5 and backlight module with short working hours, high assembly efficiency and consistent display quality. group. [Prior Art] A non-self-luminous flat panel display, such as a liquid crystal display or a liquid crystal television, needs to be assembled with a backlight module to provide a light source for displaying a picture. As shown in FIG. 1 , the conventional sidelight type backlight module 丨 is mainly composed of a bottom frame 11 , a multi-layer overlapping optical film 12 carried by the same, a cold cathode lamp 13 mounted on the side of the bottom frame n, and a lamp cover. 14 and other structures. The cold cathode fluorescent lamp 13 is housed in a lamp cover 14 made of a material such as metal which is excellent in reflection and strength. Since the structural strength of the cold cathode lamp tube 13 is lower than 15 and is not damaged by the vibration caused by the collision, a cold rubber is usually provided around the tube 13 and shown in Fig. 2) to absorb the vibration. Please refer to Figure 2. In order to increase the space efficiency, the 导-type light guide plate 122 is formed into a wedge-shaped cross-section, and FIG. 2 shows the thicker side edge and the thinner side edge of the 稜鏡-type light guide plate 122 respectively (FIG. 1) AA, at the line segment) 2〇 schematic diagram of the section. After the cold cathode lamp 13 emits the light source, most of the light is incident from the thicker side edge of the 导-shaped light guide plate 122 into the 稜鏡-shaped light guide plate 122 by the help of the lamp cover 14, and total reflection occurs therein. It is transmitted to the thinner side edge of the 导-type light guide plate 122. At this time, when the light passes through the diffusion point (not shown) of the 导-type light guide plate 122 5 M326175, it spreads to various angles, and a part of the light can be emitted from the top surface of the 导-type light guide plate 122. As a display panel (not shown), a light source for the face is displayed. On the other hand, the reflective sheet 121 under the 导-type light guide plate 122 can reflect the light emitted from the bottom surface 5 of the 导-type light guide plate 122, and return it to the 导-type light guide plate 122 to increase the effective light source. Utilization. The light concentrating sheet 123 and the upper diffusing sheet 124 affect the brightness and uniformity of the light source to increase the brightness of the light source and to make it more uniform. Therefore, after the optical characteristics of the light from the cold cathode lamp 13 are adjusted through the laminated optical films 12, the edge type backlight module 丨 becomes a uniform surface light source. However, the 导-type light guide plate 122 cannot be designed with a bump or a corner for positioning. Therefore, in the assembly process of the conventional 导-type light guide plate 122, the thicker side of the 导-type light guide plate 122 needs to be manually operated. The edge is interposed between the bottom frame 11 and the lamp cover 14, and a fixing tape 15 (shown in FIG. 1) is attached to the bottom frame 11 corresponding to the thinner side of the 导-shaped light guide plate 122 (shown in FIG. 1). The light board ι22 is the father; the end edge of the one side is fixed to the bottom frame 11 by the fixing tape 15. However, when the operator performs the assembly, the depth h of the thicker side edge of each of the 导-shaped light guide plates 122 is often different due to human factors, and the display quality of each of the side-light type backlight modules 1 is The difference between good and bad. In addition, in the process of the group 20, it is also often caused that the operator's improper application force causes the intrusion depth of the 导-type light guide plate 122 to be poor, which makes the subsequent assembly difficult to perform, thereby causing lengthening of working hours, reduction of efficiency, and decline in product shipment rate.

The bottom frame 21 includes a main frame body portion 211, a * side frame portion 212, and a plurality of blocking portions 213. The bottom frame 21 of this embodiment is a rubber 9 M326175 frame made of a resin material. The main frame body 211 has a first surface 2111 and a second surface 2112, and the first surface 2111 corresponds to the second surface 2112. The side frame body portion 212 is disposed on one side of the main frame body portion 211, and the blocking portion 213 is disposed on the second surface 2112 at a position adjacent to the side frame body portion 211, respectively. In the present embodiment, the 5 blocking portions 213 are disposed along a straight line.

The light guide plate 242 of this embodiment is a wedge-shaped 导-type light guide plate which is disposed on the side of the light source 23 to guide the light source 23 to be emitted from the top surface of the light guide plate 242. The reflection sheet 241 is disposed under the light guide plate 242 to reflect the light emitted from the bottom surface of the light guide plate 242 back into the light guide plate 242, thereby increasing the usability of the light source.
