[0049] Unless otherwise defined, all words used herein (including technical and scientific terms) have their ordinary meanings as understood by those skilled in the art. Furthermore, the definitions of the above-mentioned words in commonly used dictionaries should be interpreted in the context of this specification as having the same meanings as those in the relevant field of the present invention. Unless otherwise explicitly defined, these words should not be interpreted as having idealized or overly formal meanings.

[0050] Please refer to Figure 1 . Figure 1 FIG. 1 is a partial cross-sectional view of a display device 100 according to an embodiment of the present invention. Figure 1 As shown, a display device 100 includes a housing 110, a display module 120, a backlight module 130, a first adhesive 140, and a second adhesive 150. The backlight module 130 and the display module 120 are stacked within the housing 110. The first adhesive 140 is bonded between the display module 120 and the backlight module 130, while the second adhesive 150 is bonded between the backlight module 130 and the housing 110. Specifically, the first adhesive 140 has opposing upper and lower surfaces 140a and 140b. The lower surface 140b is completely bonded to the backlight module 130, while the upper surface 140a is completely bonded to the display module 120. In practical applications, the first adhesive 140 is an optically transparent adhesive, such as an optically transparent resin, and the first adhesive 140 is glue or double-sided tape.

[0051] Specifically, if Figure 1 As shown, the housing 110 includes a connected wall panel 111 and a bottom panel 112. In practice, the wall panel 111 is connected to the edge of the bottom panel 112, and the wall panel 111 and the bottom panel 112 together define a space SP. The display module 120 is located within the space SP of the housing 110. It is worth noting that in this embodiment, the display module 120, the first adhesive 140, the backlight module 130, the second adhesive 150, and the bottom panel 112 at least partially overlap in sequence along the vertical direction DV.

[0052] More specifically, if Figure 1As shown, the display module 120 includes a display panel 121, a transparent cover plate 122, and a third adhesive 123. The display panel 121 is located between the transparent cover plate 122 and the backlight module 130. The upper surface 140a of the first adhesive 140 is completely adhered to the display panel 121. The third adhesive 123 is bonded between the display panel 121 and the transparent cover plate 122 along a vertical direction DV. Furthermore, the third adhesive 123 has opposing upper surfaces 123a and lower surfaces 123b. The upper surface 123a is completely adhered to the transparent cover plate 122, while the lower surface 123b is completely adhered to the display panel 121. In other words, the first adhesive 140 and the third adhesive 123 are completely adhered to opposite sides of the display panel 121. In practical applications, similarly to the first adhesive 140, the third adhesive 123 can also be an optically transparent adhesive, such as an optically transparent resin.

[0053] Furthermore, if Figure 1 As shown, the transparent cover plate 122 of the display module 120 is separated from the wall plate 111 of the housing 110. In other words, the transparent cover plate 122 and the wall plate 111 do not directly contact each other, and a gap GP is formed between the transparent cover plate 122 and the wall plate 111. Because the first adhesive 140 is bonded between the display module 120 and the backlight module 130 in the vertical direction DV, and the transparent cover plate 122 does not directly contact the wall plate 111, the bezel width of the display device 100 is effectively narrowed, thereby improving the practicality and visual effect of the display device 100.

[0054] Furthermore, the top of the wall panel 111 is coplanar with or higher than the transparent cover panel 122 in the vertical direction DV. Therefore, the wall panel 111 of the housing 110 can completely surround the display module 120, which can effectively reduce the chance of light leakage from the display device 100.

[0055] In addition, if Figure 1 As shown, the display panel 121 of the display module 120 is recessed relative to the transparent cover 122. Specifically, the edge of the display panel 121 is further away from the wall panel 111 of the housing 110 than the edge of the transparent cover 122. A recessed distance R is defined between the edge of the display panel 121 and the edge of the transparent cover 122. While the recessed distance R is practically less than 5 mm, the present invention is not limited thereto. Furthermore, the display module 120 includes a light-shielding adhesive 124 that connects the side of the transparent cover 122 facing the backlight module 130 and the side of the display panel 121 to reduce light leakage from the display module 120.

[0056] Furthermore, if Figure 1As shown, the housing 110 further includes a light absorbing layer 113. The light absorbing layer 113 is disposed on the side of the wall panel 111 facing the space SP, and the light absorbing layer 113 is at least partially aligned with the display module 120 to reduce the chance of light leakage from the display device 100. In practical applications, the light absorbing layer 113 can be painted black.

[0057] On the other hand, Figure 1 As shown, the backlight module 130 includes a back panel 131, side panels 132, multiple optical films 133, supporting glass 134, and adhesive tape 135. The side panels 132 are located between the optical films 133 and the back panel 131. The side panels 132 can actually be cavity reflectors, while the back panel 131 is provided with a printed circuit board 136 and a light source (not shown). The supporting glass 134 is stacked on the side of the optical films 133 away from the back panel 131 and provides a certain amount of pressure on the optical films 133. The adhesive tape 135 is adhered to the outer side of the side panels 132, the side of the supporting glass 134 away from the back panel 131, and the side of the back panel 131 away from the supporting glass 134 to prevent displacement between the side panels 132, the supporting glass 134, and the back panel 131, thereby fixing the structure of the backlight module 130. Depending on the actual situation, the side panels 132 can be fixed to the back panel 131 using fasteners such as screws. More specifically, the first adhesive 140 is bonded between the display panel 121 of the display module 120 and the supporting glass 134 of the backlight module 130 , and the second adhesive 150 is bonded between the back plate 131 of the backlight module 130 and the bottom plate 112 of the housing 110 .

[0058] In practical applications, the side of the tape 135 that is attached to the side panels 132, the supporting glass 134, and the back panel 131 is white to provide a light-reflecting effect. Conversely, the side of the tape 135 that is not facing the side panels 132, the supporting glass 134, and the back panel 131 is black to provide a light-absorbing effect.

[0059] It is worth noting that in this embodiment, if Figure 1 As shown, the supporting glass 134 of the backlight module 130 directly abuts against the side of the optical film 133 away from the back plate 131. In other words, there is no adhesive material between the supporting glass 134 and the optical film 133.

[0060] Furthermore, if Figure 1 As shown, the first adhesive 140 at least partially covers the tape 135 of the backlight module 130 , which can effectively prevent the tape 135 from being separated from the supporting glass 134 , thereby improving the structural stability of the display device 100 .

[0061] Please refer to Figures 2-3 . Figures 2-3 To illustrate Figure 1 Schematic diagram of the installation process of the display device 100. During the installation process of the display device 100, as shown in FIG. Figure 2 As shown, the user first applies the first adhesive 140 between the display module 120 and the backlight module 130. Figure 3 As shown, the user places the connected display module 120 and backlight module 130 into the space SP of the housing 110 and adheres them between the backlight module 130 and the bottom plate 112 of the housing 110 using the second adhesive 150. At this point, the installation of the display device 100 is complete. The simple and easy installation of the display device 100 effectively reduces installation costs.

[0062] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0063] (1) Since the first adhesive is bonded between the display module and the backlight module in the vertical direction and the transparent cover does not directly contact the wall panel, the frame width of the display device can be effectively narrowed, thereby improving the practicality and visual effect of the display device.

[0064] (2) Since the display device is simple and easy to install, the installation cost can be effectively reduced.

[0065] Although the present invention has been disclosed above in terms of embodiments, this is not intended to limit the present invention. Anyone skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended patent applications.
