Figure 2 FIG. 1 is a partial view of a display device according to the first embodiment. Figure 3 for Figure 2 The display device 100 includes an outer frame 110, a backlight module 130 and a display panel 150. In this embodiment, in order to conveniently illustrate the structure between the outer frame 110 and the backlight module 130, the display panel 150 mainly used for displaying images is oriented downward in the figure.

[0046] The backlight module 130 is accommodated in the outer frame 110. The backlight module 130 has a backlight assembly 131 and a back frame 132. The backlight assembly 131 is disposed on the back frame 132. There is a gap S between the back frame 132 and the outer frame 110. Figure 3 As shown, the air flow can flow through the gap S to the outside and inside the display device 100 .

[0047] The display panel 150 is attached to the outer frame 110 via the first colloid 170 and is located on the opposite side of the backlight module 130. Figure 3As shown, the backlight module 130 is disposed on the upper side of the display panel 150. In addition, since the display panel 150 is attached to the outer frame 110 by the first colloid 170, the channel or gap on one side of the display panel 150 connecting the outside and the inside of the display device 100 is closed, so that the airflow cannot flow from one side of the display panel 150, and can only flow from the gap S to the inside and outside of the display device 100. In this embodiment, the first colloid 170 is, for example, a double-sided tape, one surface of the first colloid 170 is attached to the outer frame 110, and the other surface thereof is attached to the display panel 150.

[0048] Depend on Figure 2 and Figure 3 It can be seen that the second colloid 190 is mostly attached to the back frame 132 and the display panel 150 along the outer frame 110, and covers the gap S. One end (the upper end in the figure) of the second colloid 190 is attached to the back frame 132, and the other end (the lower end in the figure) of the second colloid 190 is attached to the display panel 150. The second colloid 190 has a groove 191, and the groove 191 makes the gap S located at the groove 191 exposed and connected to the outside. In this embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the second colloid 190 surrounds the display device 100 and shields the gap S between the back frame 132 and the display panel 150. In order to allow airflow to pass through the gap S, a slot 191 is provided in the second colloid 190, and the gap S is exposed. In this way, the airflow can flow through the gap S to the outside and the display device 100 via the slot 191. In this embodiment, the second colloid 190 is, for example, a single-sided tape.

[0049] Specifically, the display device 100 is provided with a slot 191 in the second colloid 190 so that the gap S at a portion of the position covered by the second colloid 190 is exposed, so that the internal space of the display device 100 can be connected to the outside through the gap S at the slot 191. In this way, the airflow can smoothly flow inside and outside the display device 100, and the expansion of the display panel 150 due to the imbalance of air pressure during air extraction is avoided, thereby affecting the display effect of the display panel 150.

[0050] In this embodiment, the cutout 191 is located on the second colloid 190 at a position corresponding to between the back frame 132 and the outer frame 110. Figure 2 and Figure 3 As shown, the gap S is the gap generated by assembly between the back frame 132 and the outer frame 110. Therefore, the slot 191 is disposed on the second colloid 190 attached between the back frame 132 and the outer frame 110 at a position corresponding to the gap S, so that the gap S is exposed to allow air to circulate.

[0051] In this embodiment, if Figure 2As shown, the slot 191 includes a first slot 1911 and a second slot 1912 , and the first slot 1911 and the second slot 1912 are respectively opened on planes that intersect vertically. In this way, air can flow inside and outside the display device 100 through the first slot 1911 and the second slot 1912 .

[0052] In this embodiment, the length of the first slot 1911 is 5 mm to 7.5 mm, and the width is 1.3 mm to 5 mm. Figure 2 As shown, the length of the first slot 1911 is preferably 5 mm, and the width is preferably 1.3 mm. The length of the second slot 1912 is 5 mm to 7.5 mm, and the width is 4.1 mm to 5.1 mm. Figure 2 As shown, the length of the second slot 1912 is preferably 5 mm, and the width is preferably 4.6 mm.

[0053] In this embodiment, if Figure 3 As shown, the outer frame 110 has a supporting portion 111 , and the supporting portion 111 extends toward the inside of the display device 100 . The display panel 150 is adhered to the supporting portion 111 through a first adhesive 170 .

[0054] In this embodiment, if Figure 3 As shown, the back frame 132 and the outer frame 110 have an airflow channel C. The airflow channel C is a space formed by the gap between the back frame 132 and the outer frame 110 due to assembly, for air to enter or leave. In addition, the slot 191 is arranged corresponding to the airflow channel C. In this way, the airflow can enter or leave the airflow channel C from the gap S through the slot 191, and flow inside and outside the display device 100 to achieve the effect of air circulation.

[0055] In this embodiment, if Figure 3 As shown, the air flow channel C is formed by the inner surface of the outer frame 110 , the lower surface of the support portion 111 and the outer surface of the back frame 132 .

[0056] See also Figure 4 and Figure 5 . Figure 4 FIG. 4 is a partial view of a display device according to a second embodiment. Figure 5 for Figure 4 A cross-sectional view along the BB section. In the second embodiment, the structure similar to the first embodiment is not described again. In the first embodiment, it is illustrated that air can flow inside and outside the display device 100 through the slot 191 and the gap S, but it is not limited thereto. In the second embodiment, the outer frame 110 has a through hole 112, which is arranged corresponding to the slot 191. Figure 4 and Figure 5As shown, the groove 191 on the second colloid 190 not only exposes the gap S, but also exposes the through hole 112. Thus, compared with the first embodiment which has only one straight gap S, the second embodiment has gaps S all around the through hole 112, so that air can flow not only from the gap S on the upper side to the inside and outside of the display device 100, but also from the gaps S exposed around the through hole 112 and having a larger area than that of the first embodiment, so as to further improve the air circulation effect.

[0057] In this embodiment, if Figure 4 As shown, the length of the first slot 1911 is preferably 5 mm, and the width is preferably 3.4 mm. The length of the second slot 1912 is preferably 5 mm, and the width is preferably 4.6 mm.

[0058] See also Figures 6 to 8 . Figure 6 FIG. 4 is a partial view of a display device according to a third embodiment. Figure 7 for Figure 6 Section view along section CC.

In the first embodiment, it is illustrated that the groove 191 includes a first groove 1911 and a second groove 1912 respectively opened on perpendicular intersecting planes, but it is not limited thereto. In the third embodiment, the groove 291 is only opened on one surface of the second colloid 290, and the second colloid 290 shields the opening of the gap S between the back frame 232 and the outer frame 210. In addition, in this embodiment, the outer frame 210 of the display device 200 has a perforation 212 and is arranged corresponding to the groove 291, so that the gap S at the perforation 212 can be exposed through the groove 291. Since the opening of the gap S located at the upper side is shielded compared to the first embodiment, in this embodiment, air enters or leaves the gap S through the perforation 212 on the outer frame 210 to achieve the effect of air circulation. In this way, the through holes 212 on the outer frame 210 that may be used to set connectors, power lines, etc. and must be exposed, or the through holes 212 used for structural engagement for assembly and disassembly can be used to set the grooves 291 at the corresponding through holes 212, thereby reducing the area of ​​the grooves 291 on the second colloid 290, increasing the adhesion effect of the second colloid 290, and maintaining the air circulation effect. Furthermore, since there is a gap S around the through hole 212, the area of ​​the gap S can be increased compared to the first embodiment to achieve a better air circulation effect.

[0059] In this embodiment, the back frame 232 has a locking portion 2321, which protrudes toward the outside and is locked in the through hole 212 of the outer frame 210. In this way, the assembly strength between the back frame 232 and the outer frame 210 is further improved.

[0060] In this embodiment, the perforation 212 is circular, oval or rectangular. Figure 6 and Figure 8 As shown, the through hole 212 can be rectangular or elliptical. In other embodiments, the through hole 212 can also be any shape.

[0061] In summary, according to an embodiment, a display device 100 is provided, in which a slot 191 is provided in the second colloid 190 to expose the gap S shielded by the second colloid 190, so that the internal space of the display device 100 can be connected to the outside through the slot 191 and the gap S. In this way, the airflow can flow smoothly inside and outside the display device 100, and the expansion of the display panel 150 due to the imbalance of air pressure is avoided, thereby affecting the display effect of the display panel 150. In addition, the area of ​​the gap S connecting the inside and the outside can be increased by providing a perforation 112 in the outer frame 110. In this way, the air circulation effect is further improved.
