New Description: [New Technology Field] This creation department is related to optical display Tpc. More specifically, it is an optical display module structure that can improve the yield of liquid crystal display products. 5 [First as technology] In response to the consideration of lightness and convenience in the selection of optical display related products, the industry has invested a lot of money and technology research and development, and has been able to develop products that are thinner and lighter. / b Taking a mobile phone as an example, the size of the liquid crystal display module is related to the thinness of the production. Please cooperate with the conventional liquid crystal display module 1 shown in the first and second figures, which comprises a liquid crystal panel 2, a flexible printed circuit board 3, a circuit board 4, a light guide plate 5, a light source and a double-sided tape 7. The light source is an LED (Light Emitting Diode) lamp 6, and the LED lamp 6 is disposed on the flexible printed circuit board 3. The two ends of the flexible printed circuit board 3 are electrically connected to the liquid 15 crystal panel 2 and the circuit board 4, respectively. And the double-sided tape 7 connects the light guide plate 5 and the flexible printed circuit board 3. 〃 However, during the post-assembly test, it is often found that the light generated by the LED lamp 6 is not completely incident on the light guide plate 5, resulting in a decrease in the efficiency of light utilization. It is found that in addition to the LED lamp ό The assembly positioning is not a good factor. It may be caused by the flexible printed circuit board 3. This is because the flexible printed circuit board 3 itself has flexibility. When it is bent, it will produce a human-made printed circuit board 3 reply. The rebound force, when the rebound force is greater than the adhesion of the double-sided tape 7, the flexible printed circuit board 3 will not be able to be closely attached to the backlight surface 5b of the light panel 5, as shown in the second figure, this situation not only creates 4 M295267 The flexible printed circuit board 3 and the circuit board 4 cannot be effectively fixed, and it is more likely to collide with other components, so that the wear and tear may occur, causing the LED lamp 6 aligned with the light incident surface 5a of the light guide plate 5 to be offset, so that the light is scattered. It is easy to diverge and cannot effectively enter the light guide plate 5, thereby causing a great utilization of light utilization efficiency and affecting the life and quality of the product. - Furthermore, since the adhesive of the double-sided tape 7 is easily affected by environmental factors such as temperature, humidity, and time, deterioration problems occur, and the liquid crystal display mode is easily affected by the repulsive force of the flexible printed circuit board 3. In the long-term use, the soft printed circuit board 3 is separated from the light guide plate 5. In view of this, the creator of the case has been carefully researched and accumulated years of experience in research and development of related products, and finally There is a creation of this creation. [New Content] ^ The main purpose of this creation is to provide an optical display module structure.
