The invention relates to a display module and its assembling method, especially a display module with waterproof function and its assembling method.

Generally speaking, a notebook computer includes a display and a mainframe, and for portability, the display is pivotally connected to the mainframe using a hinge so that the display can be opened or closed relative to the mainframe. In addition, in order to transmit signals between the display and the base, the opposite ends of some cables must be electrically connected to the display and the base respectively. Therefore, the casing of the display must be provided with an opening for the hinge shaft and the cable to pass through. As a result, moisture may enter the display through the opening in the casing, which may cause the electronic components in the display to malfunction.

In order to prevent water vapor from entering the display through the opening of the case, the military notebook computer is additionally provided with a metal cover for covering the hinge shaft and the cable on the display case, and then the metal cover is covered and sealed to prevent Moisture enters the display through the opening.

However, although the additional metal cover can prevent water from entering the display through the opening, it will increase the thickness of the display case. Therefore, the waterproof method provided with the additional metal cover does not meet the narrow frame requirements of the display of the commercial notebook computer, thereby making it difficult for the display of the notebook computer to simultaneously meet the requirements of waterproof and narrow frame.

The present invention is to provide a display module and an assembling method thereof to prevent the display module from being waterproof only by using an additional metal cover, and it is difficult to take into account both the waterproofing of the display module and the requirement of the narrow frame.

FIG. 3 is an exploded view of the display module of FIG. 1. 4 is a partially enlarged view of an exploded view of the display module of FIG. 1.

The display module 10 of this embodiment is, for example, a display module 10 of a portable computer (not shown). The display module 10 includes a casing 100, a display panel 200, two pivotal members 300, an outer cover 400, a plurality of cables 500, and two waterproof structures 600.

The casing 100 includes a casing 101 and a frame 102 that are fixed. The frame 102 surrounds the display panel 200 so that the display panel 200 is disposed on the frame 102. The casing 101 surrounds the frame 102 and covers one side of the display panel 200.

The two pivoting members 300 each include a first fixing portion 301, a pivoting portion 302 and a second fixing portion 303. In each pivoting member 300, opposite sides of the pivoting portion 302 are connected to the first fixing portion 301 and the second fixing portion 303, respectively. The two first fixing portions 301 are respectively fixed to the two ends on the side of the frame 102. The two second fixing portions 303 are fixed to a main base (not shown) of the portable computer, for example.

The outer cover 400 is fixed to one side of the housing 101 and includes a cover 401, two end covers 402 and a fixing frame 403. The two end covers 402 are respectively disposed on opposite sides of the cover body 401. The opposite ends of the fixing frame 403 are respectively fixed to the two-end cover 402 to maintain the relative positions of the two-end cover 402. The two end caps 402 each have an opening 4020 and a receiving slot 4021. The two first fixing portions 301 are accommodated in the outer cover 400. The two pivotal portions 302 pass through the two openings 4020 respectively. The second fixing portion 303 is located outside the outer cover 400. The opening 4020 and the accommodating groove 4021 on the same end cap 402 communicate with each other.

A plurality of cables 500 respectively pass through the two openings 4020, and the opposite ends of the cables 500 are electrically connected to the display panel 200 and a mainframe of the portable computer, respectively, so that the display panel 200 can transmit signals to the mainframe .

Please refer to Figures 3 to 5. FIG. 5 is a partially enlarged view of a schematic cross-sectional view of the display module of FIG. 1.

The two waterproof structures 600 are respectively located in the two accommodating grooves 4021 of the second end cover 402, and the outer shapes of the two accommodating grooves 4021 match the outer shapes of the two waterproof structures 600, respectively. In this way, the two waterproof structures 600 can respectively cover the two pivotal portions 302 and the cable 500 passing through the two openings 4020 to respectively close the two openings 4020. In addition, the fixing brackets 403 are respectively located in the two grooves 601 of the second waterproof structure 600.

The second waterproof structure 600 is formed by, for example, grouting. For example, when the two-end cover 402 is disposed on the cover 401, the relative position of the two-end cover 402 is first fixed by the fixing frame 403. Then, a waterproof glue (not shown) is poured into the two receiving grooves 4021 of the two end caps 402 respectively. After the waterproof glue is cured, two waterproof structures 600 are formed, and the shapes of the two waterproof structures 600 are matched with the shapes of the two accommodating grooves 4021. In addition, since the fixing frame 403 is fixed to the two end caps 402, the two waterproof structures 600 after curing each have a groove 601, and the shape of the groove 601 matches the shape of the fixing frame 403.

In addition, the arrangement of the end cover 402 is not intended to limit the present invention. In other embodiments, the end cover may be omitted and the waterproof glue may be directly poured into the cover body to form a waterproof structure. In the embodiment where the end cover is omitted, the fixing frame may also be omitted.

Furthermore, the present invention is not limited to the number of the pivoting member 300, the end cover 402, the opening 4020, and the waterproof structure 600. In other embodiments, it may include only one pivoting member, and the first of the pivoting member The fixing part is fixed on one side of the frame. In the embodiment including only one pivoting member, there is no need to provide two end caps, but only one end cap having an opening and a receiving groove needs to be provided on one side of the cover body. In this way, it is only necessary to form a waterproof structure in the accommodating groove of the end cover, and the pivoting portion and the cable covering the pivoting member are used to close the opening. In addition, in an embodiment where only one end cap is provided, the fixing brackets for fixing the relative positions of different end caps may also be omitted.

In this embodiment, the display module 10 may further include a sealing plate 700. The sealing plate 700 is sandwiched between the frame 102 and the casing 101, and the Young's coefficient of the material that makes the sealing plate 700 is smaller than the Young's coefficient of the material that makes the frame 102 and the casing 101. In other words, the frame 102 and the casing 101 can penetrate the compression sealing plate 700, so that the deformed sealing plate 700 can be tightly sandwiched between the frame 102 and the casing 101 to achieve a sealing effect, thereby preventing moisture from contacting the frame 102 The surrounded display panel 200.

However, the present invention is not limited to the arrangement of the sealing plate 700. In other embodiments, there is no need to interpose the sealing plate between the frame and the housing, and only the waterproof structure prevents moisture from entering the housing and contacting the display panel .

According to the display module and the assembling method disclosed in the above embodiments, since the waterproof structure covers the pivotal portion and the cable to close at least one opening, the moisture cannot enter the housing through the opening to contact the display panel. In this way, the display panel will not malfunction due to contact with moisture. In addition, the waterproof structure is formed in the openings originally provided for the pivoting portions and the cables by grouting. Therefore, the installation of the waterproof structure does not increase the thickness of the frame or the shell, so that the display module can simultaneously take into account the display module Waterproof and narrow frame requirements.

Although the present invention is disclosed as above with the foregoing embodiments, it is not intended to limit the present invention. Any person familiar with similar arts can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of patent protection for inventions shall be subject to the scope defined in the patent application scope attached to this specification.
