The supporting surface 121 may be the outer surface of the iron frame or the plastic frame itself, or the outer surface of a cushioning member such as rubber or silicone provided on the supporting member 121, or a single-sided adhesive provided on the supporting member 121. No glue surface. In this embodiment, the supporting member 12 is, for example, a plastic frame of a backlight module or a light guide plate clamping frame; however, in different embodiments, the supporting member 12 may also be an inner frame, an outer frame, or other structural components of the system. The rubber strip group 13 is also extended along the first side 1113 between the bottom surface of the first substrate 111 and the support surface 121 of the support member 12. The rubber strip group 13 includes first rubber strips 131 and Two rubber strips 132. In this embodiment, the first rubber strip 131 is aligned with the first side edge 1113, that is, the first rubber strip 131 is closer to the first side edge 1113 than the second rubber strip 132. , But not limited to this. In this embodiment, the first adhesive strip 131 and the second adhesive strip 132 are exemplified by double-sided tape, but are not limited thereto. For example, they may be coated strip-shaped adhesive layers.

In this embodiment, the first rubber strip 131 is adhered to the bottom surface 1111 of the first substrate 111, and the second rubber strip 132 is adhered to the support surface 121 of the support member 12. In addition, the rubber strip group 13 further includes a main diaphragm 133 disposed between the first rubber strip 131 and the second rubber strip 132. The main diaphragm 133 is made of, for example, polyethylene terephthalate (PET). , But not beyond that. The main diaphragm 133 is elongated, and its long side and the long sides of the two rubber strips are both extended in the same direction (the direction parallel to D1). In the embodiment, the aforementioned “between” means that the middle portion of the main diaphragm 133 will pass The gap formed between the first rubber strip 131 and the second rubber strip 132 when they are arranged side by side.

In addition, in this embodiment, the main diaphragm 133 is adhered to the first adhesive strip 131 and the second adhesive strip 132 with two opposite surfaces. In this embodiment, the main diaphragm 133 can be roughly defined into three areas, namely a first portion 1331, a second portion 1332 opposite to the first portion 1331, and a connecting portion connecting the first portion 1331 and the second portion 1332. 1333. The opposite first portion 1331 and the second portion 1332 in this embodiment refer to areas that are distributed on both sides of the connecting portion 1333. The first portion 1331 is adhered to the side of the first rubber strip 131 facing the support 121, the second portion 1332 is adhered to one side of the second rubber strip 132 toward the bottom surface 1111, and the connecting portion 1333 extends through the first rubber strip 131 and the first portion. The gap between the two rubber strips 132.

According to this, the first adhesive strip 131 is adhered to the bottom surface 1111 and directly or indirectly passes through the first portion 1331 of the main diaphragm 133 and abuts the support surface 121, and because PET is not adhesive, the first adhesive strip 131 does not adhere. On the supporting surface 121. Similarly, the second adhesive strip 132 is adhered to the supporting surface 121 and directly or indirectly penetrates the second portion 1332 of the main diaphragm 133 to contact the bottom surface 1111. Since PET is not adhesive, the second adhesive strip 132 is not Will stick to the bottom surface 1111.

With this design, the first rubber strip 131 and the second rubber strip 132 can jointly form a plane supporting the bottom surface 1111, and thus the plane cross-section width formed by the first rubber strip 131 and the second rubber strip 132 can be wider than the single first rubber strip 131 or the second rubber strip 132. A stable and sufficient support state of the display panel 11 can be provided. At the same time, since the first rubber strip 131 and the second rubber strip 132 are respectively attached to the bottom surface 1111 and the support surface 121, the adhesiveness can also be controlled so that the display panel 11 can be easily separated from the support surface 121. In addition, since the first rubber strip 131 and the second rubber strip 132 are connected by the main diaphragm 133, the assembly can be completed in one process during assembly, which saves labor time. It should be noted that in order to achieve good supportability, convenience during heavy work, and success rate, in this embodiment, the relative positions of the display panel 11 and the rubber strip group 13 are Has its special design, but not limited to this.

Please continue to refer to FIG. 1B, the area where the first substrate 111 and the second substrate 112 overlap, that is, the second substrate 112 corresponds to the vertical projection range on the bottom surface 1111 of the first substrate 111, which mainly refers to the The overlapping area from the vertical projection position of the two side edges 1121 (closer to one side of the first side edge 1113) on the bottom surface 1111 is defined as the substrate overlapping area R0. The vertical projection range of the first rubber strip 131 corresponding to the bottom surface 1111 is defined as the first region R1. In this embodiment, the first region R1 will fall outside the substrate overlapping region R0. In addition, the vertical projection of the second side 1121 of the second substrate 112 corresponding to the bottom surface 1111 falls outside the first region R1.

In addition, the vertical projection range of the second rubber strip 132 corresponding to the bottom surface 1111 is defined as the second region R2. In this embodiment, the second region R2 and the substrate overlapping region R0 may partially overlap each other. In addition, the vertical projection of the second side 1121 of the second substrate 112 corresponding to the bottom surface 1111 and the second region R2 may partially overlap. Since the substrate overlapping region R0 is supported by the member of the second region R2 (ie, the second portion 1332 of the main diaphragm 133, the second rubber strip 132), the first substrate 111 can be avoided when the display panel 11 is pressed down by the machine The second substrate 112 is broken along the second side edge 1121. In addition, since the main diaphragm 133 is not sticky, when the factory is in heavy work, the display panel 11 can be easily lifted to reduce the damage rate.

In an embodiment, since the second region R2 needs to bear the weight of the two substrates overlapping, the thickness of the first rubber strip 131 and the second rubber strip 132 may be slightly different. As shown in FIG. 1C, the second rubber strip 132 The thickness H2 may be slightly larger than the thickness H1 of the first rubber strip 131. According to this, when the display panel is stacked on the rubber strip group, the second rubber strip 132 closer to the center of the display panel 11 can share a larger load.

Please refer to FIG. 2 for another embodiment of the present invention. The rubber strip group 13 further includes a third rubber The strip 134 is preferably, but not limited to, using double-sided tape, and is disposed and adhered to the side surface 122 of the support member 12. In addition, the rubber strip group 13 further includes a secondary diaphragm 135 connected to the primary diaphragm 133. In this embodiment, the secondary diaphragm 135 is formed by integrally extending the primary diaphragm 133 toward the side surface 122 of the support member 12. By virtue of the adhesiveness of the third rubber strip 134, the auxiliary diaphragm 135 is adhered to the side surface 122 of the support member 12. According to this design, the fixation between the rubber strip group 13, the support member 12 and the display panel 11 can be improved.

Please refer to FIG. 3A and FIG. 3B for another embodiment of the present invention. The overall structure is substantially the same as the previous embodiment, except that the pre-split line 14 can be pressed in advance on the connecting portion 1333 of the main diaphragm 133, which is mainly beneficial to disconnect the main diaphragm 133. From the top view of FIG. 3A, the pre-splitting line 14 is pressed on the connecting portion 1333 and is parallel to the extending direction of the first rubber strip 131 or the second rubber strip 132. According to this design, when the factory is engaged in heavy work, as shown in FIG. 3B, the pre-split line 14 can be broken through the related fixture 15 to facilitate subsequent operations. In practical applications, the situation of pulling the panel can be reduced in this way. When the size of the display panel is extremely thin, it is less likely to be broken.

In other embodiments, as shown in FIG. 4, the main diaphragm 133 may be presented as an independent first portion 1331 and a second portion 1332, that is, the main diaphragm 133 does not have a connection portion 1333. In this embodiment, the first adhesive strip 131 and the second adhesive strip 132 are both double-sided tapes. Therefore, the first portion 1331 and the second portion 1332 can respectively adhere the first adhesive strip 131 and the second adhesive strip 132 to one side. Sex is blocked, leaving only one side of the sticky for connection with the bottom surface 1111 and the support surface 121. In this embodiment, although the first portion 1331 and the second portion 1332 are separated from each other, the same supportability and convenience and safety of heavy industry can be maintained. In addition, in different embodiments, when the first adhesive strip 131 and the second adhesive strip 132 are both single-sided adhesive, the main film 133 may not be used to block the adhesiveness of one side to achieve the desired effect.

According to another embodiment of the present invention, the attachment position of the main diaphragm 133 is changed. As shown in FIG. 5, the first rubber strip 131 is adhered to the support surface 121, and the second rubber strip 132 is adhered to the bottom surface 1111. Main membrane A first portion 1331 of the sheet 133 is adhered to a side of the first adhesive strip 131 facing the bottom surface 1111, a second portion 1332 is adhered to a side of the second adhesive strip 132 toward the support surface 121, and the connecting portion 1333 extends through the first adhesive strip 131 And the gap between the second rubber strip 132. According to this design, the display panel is less likely to float due to the adhesive force of the second adhesive strip 132. In other embodiments, the first portion 1331 and the second portion 1332 of the main diaphragm 133 may be separately provided, and other detailed structures and variations are the same as those in the foregoing embodiment, and are not described herein again.
