Fig. 2B is a cross-sectional view taken along line 2B-2B' in Fig. 2A. The barrier strip 120' is a multi-layer structure comprising an impermeable adhesive layer 120, a first release layer 121' and a second release layer 122'. The anti-seepage adhesive layer 120 has a first adhesive surface 120s1 and an opposite surface 120s2. The first release layer 121' is adhered to the first adhesive surface 120s1 of the anti-seepage adhesive layer 120. The second release layer 122' is adhered to the opposite surface 120s2 of the barrier layer 120. The first release layer 121' protects the first adhesive surface 120s1 of the anti-seepage adhesive layer 120, and prevents the first adhesive surface 120s1 from being exposed and contaminated. In one embodiment, the first release layer 121' has a thickness t1 greater than 0.9 mm. The second release layer 122' has a sufficient thickness to enhance the support of the barrier strip 120', thereby enhancing the adhesion barrier strip 120' The operability of the display module 100. In one embodiment, the thickness of the second release layer 122' is greater than 1 mm, which is sufficient to support the barrier strip 120', making it easy to apply.

As shown in the enlarged view of FIG. 2B, the anti-seepage adhesive layer 120 includes an adhesive layer 121 and a carrier layer 122. The adhesive layer 121 has a first adhesive surface 120s1 and a second adhesive surface 121s1, and the carrier layer 122 has a bearing surface 122s1 and an opposite surface 120s2. The adhesive layer 121 is adhered to the bearing surface 122s1 by the second adhesive surface 121s1.

In terms of thickness, in one embodiment, the thickness t31 of the adhesive layer 121 is between about 25 microns and 50 microns, preferably but not limited to between 30 microns and 40 microns, and the thickness of the carrier layer 122 is t32. It is between about 5 microns and 30 microns, preferably but not limited to between 10 microns and 20 microns. In terms of materials, the material of the carrier layer 122 may include polyethylene terephthalate (PET), other light transmissive or opaque resins.

As shown in Fig. 3, the first release layer 121' and the barrier adhesive layer 120 are separated to expose the first adhesive surface 120s1 of the barrier adhesive layer 120. In the subsequent step, the anti-seepage adhesive layer 120 is adhered to the display module 100 with the exposed first adhesive surface 120s1.

In terms of viscosity, the first release layer 121' is less viscous to the barrier layer 120 than the second release layer 122' and the barrier layer 120. Since the first release layer 121' has low adhesion to the barrier adhesive layer 120, the first release layer 121' and the barrier adhesion layer 120 can be easily separated. Further, the color of the first release layer 121' and the color of the second release layer 122' may be the same or different.

As shown in FIG. 4A and FIG. 4B, FIG. 4A is a top view of the anti-smear adhesive layer 120 of FIG. 3 adhered to the display module 100, and FIG. 4B is a cross-sectional view of the 4A-4B along the direction 4B-4B′. . In Fig. 4A, an enlarged view A' is a partially enlarged perspective view, and an enlarged view B' is a partially enlarged front view.

The first adhesive surface 120s1 (Fig. 3) of the anti-seepage adhesive layer 120 is adhered to the edge of the optical film 1121.

In terms of color, the color of the anti-slip adhesive layer 120 may be the same as or different from the color of the optical film 1121. When the color of the anti-seepage adhesive layer 120 is different from the color of the optical film 1121, the adhesion area between the anti-seepage adhesive layer 120 and the optical film 1121 can be discriminated from the appearance, and it can be determined whether the anti-seepage adhesive layer 120 is accurately adhered to the optical film. On 1121. In this way, the adhesion yield of the anti-seepage adhesive layer 120 and the display module 100 can be improved.

As shown in FIGS. 5A and 5B, FIG. 5A is a partial schematic view showing the anti-seepage adhesive layer 120 of FIG. 4A bent to the back of the frame, and FIG. 5B is a view along the direction 5B-5B' of FIG. 5A. Cutaway view. The anti-smear adhesive layer 120 of FIG. 4B is bent to the back surface 113b of the frame 113, wherein the first adhesive portion 123 of the anti-seepage adhesive layer 120 is bent around the first folding line L1 to the first side surface 113s1, and then bent to the frame 113. The back surface 113b, the first adhesive portion 123 after the bending is applied and adhered to the first side surface 113s1 of the frame 113, and the second adhesive portion 124 of the anti-slip adhesive layer 120 is bent around the second folding line L2 to the second side surface 113s2. Then, the second adhesive portion 124 is bent and adhered to the second side surface 113s2 of the frame 113. After the first adhesive portion 123 is adhered to the frame 113 , the first protruding portion 126 can be adhered to the second adhesive portion 124 about the third axial direction Z. On the first side 113s1 and the second side At the corner of 113s2, the first adhesive portion 123 and the second adhesive portion 124 do not overlap each other. Therefore, there is a gap P1 between the first adhesive portion 123 and the second adhesive portion 124 to expose the display module 100 and adhere to the second. The first protrusion 126 of the adhesive portion 124 can cover the gap P1. In this way, the optical glue 11 can be avoided during the bonding process between the display panel 112 and the touch panel 12 (shown in FIG. 9). Fig. 9) overflows into the gap of the display module 100 through the slit P1.

The first protrusion 126 has a width W1 which is substantially equal to the width W2 of the second side surface 113s2 to cover the width of the second side surface 113s2 and the entire gap P1, but is not limited thereto. In this way, during the bonding process between the display module 100 and the touch panel 12 (shown in FIG. 9), the optical glue 11 (shown in FIG. 9) can be prevented from seeping through the gap P1 to the display module 100. Inside the gap.

In this embodiment, since the first angle A1 and the second angle A2 are substantially close to 90 degrees, the first sub-bevel C11 and the second sub-bevel C12 adhered to the back surface 113b are substantially parallel and do not overlap each other. Further, the thickness (thickness in the Z-axis direction) of the first adhesive portion 123 adhered to the back surface 113b and the second adhesive portion 124 are relatively uniform. Further, when the first adhesive portion 123 and the second adhesive portion 124 overlap in the third axial direction Z, the thickness of the overlap is thicker relative to the periphery, which causes the display module 100 and the touch panel to be attached. During the process, the overlap and the assembly tool are squeezed to withstand excessive stress. When the overlap is subjected to excessive stress, damage to the display panel 112 may result. In contrast, in the present embodiment, since the first adhesive portion 123 and the second adhesive portion 124 do not overlap, there is no problem that the thickness of the overlap portion is thick relative to the periphery, and the problem that the display panel 112 is damaged due to excessive stress can be avoided.

The length of the portion of the back surface 113b of the frame 113 covered by the barrier layer 120 is Y1. If the length Y1 of the back surface 113b of the anti-seepage adhesive layer 120 covering the frame 113 is too short, the elasticity of the anti-seepage adhesive layer 120 (the anti-seepage adhesive layer 120 of this stage is still adhered to the second release film 122') is greater than the adhesive area ( The area of the length Y1 is detached from the back surface 113b of the frame 113. In one embodiment, the length Y1 is between about 2 mm and 5 mm, which provides the proper elasticity and adhesion area of the anti-slip adhesive layer 120, which is sufficient for the anti-slip adhesive layer 120 to closely adhere to the back surface 113b of the frame 113.

Further, as shown in FIG. 5B, the barrier adhesive layer 120 is not adhered to overlap with the reflective sheet 1114. Further, when the anti-smear adhesive layer 120 and the reflective sheet 1114 are overlapped, the thickness of the overlap is thicker than that of the reflective sheet 1114, which will cause the overlap between the display module 100 and the touch panel during the bonding process. Excessive stresses may cause damage to the display panel 112 or negatively affect the display quality of the display panel 112. In contrast, in the present embodiment, since the anti-seepage adhesive layer 120 and the reflective sheet 1114 do not overlap, there is no problem that the thickness of the overlapping portion is thicker than that of the reflective sheet 1114, thereby preventing the display panel 112 from being damaged or of poor quality due to excessive stress. problem.

In terms of color, the color of the anti-slip adhesive layer 120 may be the same as or different from the color of the back surface 113b of the frame 113. When the color of the anti-seepage adhesive layer 120 is different from the color of the back surface 113b of the frame 113, the adhesion area of the anti-seepage adhesive layer 120 and the frame 113 can be discerned from the appearance, thereby improving the accuracy in the alignment and improving the anti-seepage. Adhesion yield of the adhesive layer 120 and the display module 100.

In addition, the structure in which the third adhesive portion 125 and the second protruding portion 127 are bent is similar to the structure in which the second adhesive portion 124 and the first protruding portion 126 are bent, and thus will not be described again.

As shown in Fig. 6, the second release layer 122' and the barrier layer 120 are separated to complete the adhesion of the barrier layer 120. Due to the step of separating the second release layer 122' and the anti-seepage adhesive layer 120 of the present embodiment, the second release layer 122' providing additional elasticity is removed, and the anti-seepage can be avoided. The adhesive layer 120 is easily driven away from the back surface 113b by the elastic force of the second release layer 122'. In another embodiment, as long as the adhesion between the barrier adhesive layer 120 and the back surface 113b is greater than the elastic force of the second release layer 122', it is also considered that the second release layer 122' and the barrier adhesive layer 120 are not separated.

As shown in FIG. 7, the step of the second embodiment of FIGS. 2A to 6 can be applied to the edge of the display module 100 with the other impermeable adhesive layer 120 on the side of the third side 113s3. . The adhesion relationship between the anti-smear adhesive layer 120 and the third side surface 113s3 on the right side of FIG. 7 is similar to the adhesion relationship between the anti-seepage adhesive layer 120 on the left side of FIG. 7 and the first side surface 113s1, and will not be described again.

As shown in Fig. 8, another barrier metal strip 130 is provided, wherein the layer structure of the barrier strip 130 can be similar to the above-described barrier strip 120' (Fig. 2B). Similar to the adhesion method of the above-mentioned anti-seepage strip 120', after separating the first release layer 121' (not shown) of the anti-seepage strip 130 and the anti-seepage adhesive layer 120 (not shown), the anti-seepage can be performed. The anti-seepage adhesive layer 120 (not shown) of the strip 130 is adhered to the edge of the optical film 1121 of the display module 100, wherein the anti-seepage strip 130 is located on the side of the second side 113s2, as shown in FIG. In this embodiment, the anti-seepage strip 130 and the anti-seepage adhesive layer 120 are adjacent to each other and overlap, so that the gap is formed to avoid the phenomenon of bleeding.

Then, the anti-seepage strip 130 of FIG. 8 can be bent to adhere the anti-seepage strip 130 to the second side 113s2 and the back surface 113b of the frame 113.

As shown in FIG. 8, another anti-seepage strip 140 is provided, wherein the structure of the anti-seepage strip 140 can be similar to the anti-seepage strip 130, which will not be described again. The manner in which the anti-smear strips 140 are adhered to the display module 100 is similar to the manner in which the anti-seepage strips 130 are adhered to the display module 100, and details are not described herein.

FIG. 9 is a view showing a bonding diagram of the display module and the touch panel of FIG. 8. This step The optical adhesive 11 is disposed between the display module 100 and the touch panel 12 to bond the display module 100 and the touch panel 12 . In the embodiment, although the optical adhesive 11 has flowability, the optical adhesive 11 can be prevented from seeping into the assembly gap of the display module 100 due to the design of the anti-seepage adhesive layer 120. After the optical adhesive 11 is cured, the optical adhesive 11 , the display module 100 , and the touch panel 12 form the touch display module 10 .

10A is a top plan view of an anti-seepage strip in accordance with another embodiment of the present invention. The anti-seepage strip 220' includes a first adhesive portion 123, a second adhesive portion 124, a third adhesive portion 125, a first protruding portion 226, a second protruding portion 227, a first oblique side C1, and a second oblique side C2. The length X1 of the first protrusion 226 and the length X2 of the second protrusion 227 of the anti-seepage strip 220' of the present embodiment may be longer than that of the above-mentioned anti-seepage strip 120'. In addition, the anti-seepage strip 220' is a multi-layer structure, and its structure is similar to that of the above-mentioned anti-seepage strip 120', and will not be described again.

FIG. 10B is a schematic view showing the anti-seepage adhesive layer of the anti-seepage strip of FIG. 10A adhered to the display device. In this embodiment, the display module 200 includes a backlight module 111 (not shown), a display panel 112 (not shown), and a frame 213.

The frame 213 includes a flap 2131 and an opening 213a. In this embodiment, an internal component 115 of the display module 200 covers or closes the opening 213a from the inside of the display module 200; in this design, the first protrusion is appropriately designed by appropriately designing the length X1 of the first protrusion 226. The portion 226 selectively covers the opening 213a or exposes at least a portion of the opening 213a. Since the inner component 115 of the display module 200 has covered or closed the opening 213a from the inside, even if the first protruding portion 226 does not cover the opening 213a, it is difficult for the optical glue or impurities to enter the display module 100 through the opening 213a. internal.

In another embodiment, the display module 200 does not have an internal component covering the opening 213a, so that the opening 213a communicates with the internal space of the display module 100. In this design, the length X1 of the first protrusion 226 can be increased. The first protrusion 226 is covered with the entire opening 213a. In this way, during the bonding process between the display panel 112 and the touch panel 12 (shown in FIG. 9 ), the optical glue 11 (shown in FIG. 9 ) can be prevented from seeping from the opening 213 a to the inside of the display module 100 . .
