Description

Reinforced structure of liquid crystal display module

The invention relates to the technical field of a liquid crystal display module, in particular to a strengthening structure capable of strengthening a module frame to protect electronic components.

At present, the development trend of mobile phones is becoming lighter and thinner. However, while the screen is thinner and thinner, the module strength is weakened. Currently, the liquid crystal display module seen in the market mobile phone includes a liquid crystal panel and a backlight module. And a plastic frame (HOUSING), a liquid crystal panel (LCD) is laminated on the backlight module, and one side of the liquid crystal panel is electrically connected to a flexible printed circuit board (FPC), and the backlight module is a light guide plate and The optical printed circuit board is soldered with a plurality of electronic components. When the liquid crystal panel and the backlight module are placed in the plastic frame, the flexible printed circuit board on the side of the backlight module bypasses the outer frame. Reflexed to the other side of the plastic frame.

When a user operates a mobile phone, there is often a problem that the mobile phone inadvertently drops, collides, or falls over due to unstable placement. Therefore, the intensive design of the internal module of the mobile phone is becoming more and more important, and the conventional module solid energy can achieve the required Purpose, but in the face of sudden drop, the screen damage is often unusable, and due to the thin and light demand, the space between the modules is increasingly compressed, and the components between the modules collide with each other due to deformation, resulting in a greatly increased chance of LCD cracking. There is a need for improvement.

In view of the lack of the prior art, the object of the present invention is to provide a liquid crystal module reinforcing structure, thereby preventing the electronic components of the liquid crystal panel and the flexible circuit board from contacting each other due to the overall deformation when the module is dropped. To prevent damage to the LCD panel.

When the film is dropped, the liquid crystal panel 22 is in direct contact with the electronic component 31 on the flexible circuit board 10 due to the overall deformation, thereby colliding with each other, thereby preventing the liquid crystal panel 22 from being damaged, and the receiving hole 23 is generally a polygonal hole. The actual position of the accommodating hole 23 and its shape and shape can be determined according to requirements, and are not limited to the embodiment of the present invention.

Referring to FIG. 3 again, it is a schematic diagram of the first embodiment of the present invention. In this embodiment, the accommodating hole 23 is mainly a polygonal and closed hole, and the electronic component 31 on the flexible circuit board is disposed in the accommodating hole 23, and in order to prevent the module frame from being deformed more than the liquid crystal panel, A reinforcing member 33 can be added to the periphery of the receiving hole 23 as a reinforcing structure. The reinforcing member 33 of the receiving hole 23 is mainly an annular member, and the annular edge of the reinforcing member 33 is mainly along the periphery of the receiving hole 23. The reinforcing element 33 and the module frame 20 and the system can be integrally formed.

Referring to FIG. 4 again, it is a schematic diagram of a second embodiment of the present invention. In this embodiment, a plurality of strong firmwares 43 are disposed on the flexible circuit board 40. The strong firmware 43 is a capacitive component on the flexible circuit board 40. The strong firmware 43 is disposed on the periphery of the flexible circuit board 40 corresponding to the receiving hole 42. The figure is disposed at the inner corner position, when the electronic component 41 is disposed in the receiving hole 42 The strong firmware 43 is tightly fitted to the corner of the receiving hole 42.

Referring to FIG. 5 again, it is a schematic diagram of a third embodiment of the present invention. In the embodiment, the accommodating hole 52 is provided with a reinforcing component 54 which is a capacitive component on the flexible circuit board 50. When the electronic component 51 is placed in the accommodating hole 52, the flexible circuit board 50 is disposed. The upper strong firmware 53 is tightly fitted to the inner periphery of the reinforcing member 54.

Referring to FIG. 6 again, it is a schematic diagram of a fourth embodiment of the present invention. The accommodating hole 62 of the embodiment has a continuous concave-toothed shape 621. The periphery 621 defines a plurality of recesses 622 in the area of the accommodating hole 62. The flexible circuit board 60 is provided with a plurality of strong firmware 63. For the capacitive element or other electronic component on the flexible circuit board 60, the strong firmware 63 is disposed at the position of the flexible circuit board 60 corresponding to the recess 622 formed by the receiving hole 62 and the periphery 621. When the electronic component 61 is placed in the recess 622 When the hole 62 is received, the strong fastener is tightly fitted to the periphery of the recess 622.
