The spirit and scope of the present invention will be apparent from the following description of the preferred embodiments of the invention. The spirit and scope of the invention are not departed.

Referring to Figure 1, there is shown a top view of an embodiment of a display module of the present invention. The display module 100 includes an outer frame 110 and a display panel 120 fixed to the outer frame 110, a light source module 130, and a backlight module (not shown). The light source module 130 is disposed on one side of the display panel 120. The backlight module is disposed at the rear of the display panel 120. The display module 100 disclosed in this embodiment adopts a narrow bezel design, and the use of the backplane is omitted, so as to meet the design requirements of thin and light, the structure and assembly manner will be described below in conjunction with specific embodiments.

Referring to FIG. 2, it is a cross-sectional view of an embodiment of a display module of the present invention along line A-A of FIG. 1. The display module 100 includes an outer frame 110, a display panel 120, and a light guide plate 140. The outer frame 110 includes a sidewall 112 and a carrying portion 114 extending from the sidewall 112. This embodiment The cross-sectional shape of the center frame 110 is approximately T-shaped, that is, the carrier portion 114 is substantially perpendicular to the sidewall 112, and the carrier portion 114 extends substantially from the middle portion of the sidewall 112 toward the center of the display module 100.

The display panel 120 is placed on the carrying portion 114 by The carrier portion 114 is positioned against it. In order to prevent the substrate of the display panel 120 from directly contacting the bearing portion 114, the display module 100 is provided with a first buffer layer 150 between the display panel 120 and the carrying portion 114 to avoid direct collision of the display panel 120 during assembly. Part 114 is damaged.

In order to effectively fix the display panel 120 in the outer frame 110, The display module 100 further includes a first adhesive 160, and the display panel 120 is fixed in the outer frame 110 by means of dispensing, that is, the first adhesive 160 is filled into the gap between the display panel 120 and the sidewall 112. g, after the first adhesive 160 is cured, the display panel 120 can be fixed in the outer frame 110 through the side adhesion between the first adhesive 160 and the display panel 120 and the sidewall 112, wherein the first adhesive 160 can be further The peripheral area of the upper surface of the display panel 120 is extended to enhance the fixing effect.

However, after the assembly of the display module 100 is completed, it is possible There is a need for heavy work due to factors such as failure of the test, and therefore the cured first adhesive 160 needs to be pulled out from the gap g, and the display panel 120 is taken out. In the stage of rework, in order to avoid the first adhesive layer 160 directly bonding to the first buffer layer 150, or because the first adhesive 160 penetrates into the gap between the display panel 120 and the carrying portion 114, the first adhesive is allowed. After the adhesive 160 is cured, the undercut portion is formed in the gap, and the first adhesive is difficult to be peeled off. The display module 100 further disposed the first spacer 170 between the first buffer layer 150 and the first adhesive 160. So that the first adhesive 160 can be easily peeled off from the gap g from.

Specifically, the first spacer 170 is disposed on the carrying portion 114 The thickness of the first spacer 170 is greater than the distance between the bottom surface 122 of the display panel 120 and the first buffer layer 150 after the display panel 120 is placed on the carrier portion 114. In other words, the thickness of the first spacer 170 needs to be greater than the thickness of the first buffer layer 150, so that the first spacer 170 positively isolates the first adhesive 160 and the first buffer layer 150 from direct bonding or It is a case where the first adhesive 160 penetrates into the gap between the display panel 120 and the carrying portion 114 to form an undercut portion after curing.

After the first adhesive 160 is cured, the first adhesive 160 The positive adhesion force with the first spacer 170 is greater than the positive adhesion between the first spacer 170 and the carrier 114, so that when an external force is applied to pull the cured first adhesive 160, the first A spacer 170 is relatively easily separated from the outer frame 110 without causing difficulty in separation due to an excessive adhesion between the first spacer 170 and the outer frame 110 at the corner of the outer frame 110.

More specifically, by providing the first partition on the carrying portion 114 The spacer 170 can have only side shear force between the first adhesive 160 and the outer frame 110 at the gap g without a positive adhesive force. The first spacer 170 is placed on the carrying portion 114, and the two adhesives are not fixed by the additional adhesive. Therefore, when the first adhesive 160 is removed, the first spacer 170 does not adhere to the outer frame. 110, and can be carried along the gap g together with the first adhesive 160.

In some embodiments, the ratio of the positive adhesion between the first adhesive 160 and the first spacer 170 to the positive adhesion between the first spacer 170 and the carrier 114 is between 0.01 and 0.8. The side shear force between the first spacer 170 and the side wall 112 and the side shear force between the first spacer 170 and the first buffer layer 150 are not more than 2 kgf/cm ² to facilitate the first spacer.

The thickness of the second spacer 172 is greater than the distance between the top surface 142 of the light guide plate 140 and the second buffer layer 152 after the light guide plate 140 is placed on the carrying portion 114. In other words, the thickness of the second spacer 172 is greater than The thickness of the second buffer layer 152 is such that the second spacer 172 positively isolates the second adhesive 162 and the second buffer layer 152. After the second adhesive 162 is cured, the second adhesive 162 and the second The positive adhesion between the spacers 172 is greater than the positive adhesion between the second spacers 172 and the carrier 114, so that when the external force is applied to pull the cured second adhesive 162, the second spacer can be made The 172 is relatively easily separated from the outer frame 110 without causing difficulty in separation due to an excessive adhesion between the second spacer 172 and the outer frame 110 at the corner of the outer frame 110. Here, the action and principle of the second spacer 172 is similar to that of the first spacer 170, and will not be described herein.

In some embodiments, the ratio of the positive adhesion between the second adhesive 162 and the second spacer 172 to the positive adhesion between the second spacer 172 and the carrier 114 is between 0.01 and 0.8. The sum of the side shear force between the second spacer 172 and the side wall 112 and the side shear force between the second spacer 172 and the second buffer layer 152 is not more than 2 kgf/cm ² to facilitate the second spacer. The 172 is separated from the second buffer layer 152 and the sidewall 112.

The optical module 180 is further included in the display module 100. Optics The diaphragm 180 is disposed between the display panel 120 and the light guide plate 140 to homogenize or brighten the light provided by the light guide plate 140.
