However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in a simple schematic manner in the drawings, and in all drawings, the same reference numerals will be used to denote the same or similar elements. And, where feasible, features of different embodiments can be applied interchangeably.

[0019] Unless otherwise defined, all terms used herein (including technical and scientific terms) have their ordinary meanings, meanings that are understandable to those skilled in the art. Furthermore, the definitions of the aforementioned terms in commonly used dictionaries should be interpreted in the context of this specification as having the meaning consistent with the relevant field of this invention. Unless specifically defined, these terms will not be interpreted as having idealized or overly formal meanings.

[0020] Please refer to Figure 1. Figure 1 is a partial cross-sectional view illustrating a display device 100 according to an embodiment of the present invention. In this embodiment, as shown in Figure 1, 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. Further, the first adhesive 140 has an upper surface 140a and a lower surface 140b opposite to each other, the lower surface 140b being completely adhered to the backlight module 130, while the upper surface 140a is completely adhered to the display module 120. In practical applications, the first adhesive 140 is an optically transparent adhesive, such as an optically transparent resin, while the first adhesive 140 is glue or double-sided tape.

[0021] Specifically, as shown in Figure 1, the housing 110 includes a connected wall panel 111 and a base plate 112. In fact, the wall panel 111 is connected to the edge of the base plate 112, and the wall panel 111 and the base plate 112 together define a space SP, within which the display module 120 is located. 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 base plate 112 are at least partially overlapped in a vertical direction DV sequence.

[0022] More specifically, as shown in Figure 1, 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 adhered vertically (DV) between the display panel 121 and the transparent cover plate 122. Furthermore, the third adhesive 123 has an upper surface 123a and a lower surface 123b, with the upper surface 123a completely adhered to the transparent cover plate 122 and the lower surface 123b 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, respectively. In practical applications, similarly, the third adhesive 123 can also be an optically transparent adhesive, such as an optically transparent resin, like the first adhesive 140.

[0023] Furthermore, as shown in Figure 1, the transparent cover plate 122 of the display module 120 and the wall panel 111 of the housing 110 are separated from each other. That is, the transparent cover plate 122 and the wall panel 111 do not directly contact each other, and a gap GP is formed between the transparent cover plate 122 and the wall panel 111. Since the first adhesive 140 is bonded to the display module 120 and the backlight module 130 on the vertical direction DV, and the transparent cover plate 122 does not directly contact the wall panel 111, the bezel width of the display device 100 can be effectively narrowed, thereby improving the practicality and visual effect of the display device 100.

[0024] Furthermore, the top of the wall panel 111 is coplanar with or higher than the transparent cover plate 122 in the vertical direction DV. Therefore, the wall panel 111 of the housing 110 can provide a complete enclosure for the display module 120, which can effectively reduce the chance of light leakage of the display device 100.

[0025] Furthermore, as shown in Figure 1, the display panel 121 of the display module 120 is recessed relative to the transparent cover plate 122. That is, the edge of the display panel 121 is further away from the wall panel 111 of the housing 110 relative to the edge of the transparent cover plate 122. An inward distance R is defined between the edge of the display panel 121 and the edge of the transparent cover plate 122. The inward distance R is actually less than 5 mm, but the present invention is not limited thereto. In addition, the display module 120 further includes a light-shielding adhesive 124, which connects the side of the transparent cover plate 122 facing the backlight module 130 and the side of the display panel 121 to reduce the chance of light leakage from the display module 120.

[0026] Furthermore, as shown in Figure 1, 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 may be black lacquer.

[0027] On the other hand, as shown in Figure 1, the backlight module 130 includes a back plate 131, a side plate 132, a plurality of optical films 133, a supporting glass 134, and adhesive tape 135. The side plate 132 is located between the optical films 133 and the back plate 131. The side plate 132 can actually be a cavity reflector, while a printed circuit board 136 and a light source (not shown) are disposed on the back plate 131. The supporting glass 134 is stacked on the side of the optical films 133 away from the back plate 131 and provides some pressure to the optical films 133. The adhesive tape 135 is adhered to the outer side of the side plate 132, the side of the supporting glass 134 away from the back plate 131, and the side of the back plate 131 away from the supporting glass 134 to prevent displacement between the side plate 132, the supporting glass 134, and the back plate 131, thereby fixing the structure of the backlight module 130. Depending on the actual situation, the side panel 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, while the second adhesive 150 is bonded between the back panel 131 of the backlight module 130 and the bottom plate 112 of the housing 110.

[0028] In practical applications, the tape 135 is white on one side of the side panel 132, supporting glass 134, and back panel 131 to provide a reflective effect. Conversely, the tape 135 is black on the side opposite to the side panel 132, supporting glass 134, and back panel 131 to provide a light-absorbing effect.

[0029] It is worth noting that in this embodiment, as shown in Figure 1, 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. That is, there is no adhesive material between the supporting glass 134 and the optical film 133.

[0030] Furthermore, as shown in Figure 1, the first adhesive 140 at least partially covers the tape 135 of the backlight module 130, which can effectively prevent the tape 135 from detaching from the supporting glass 134, thereby improving the structural stability of the display device 100.

[0031] Please refer to Figures 2 and 3. Figures 2 and 3 are schematic diagrams illustrating the installation process of the display device 100 shown in Figure 1. During the installation process of the display device 100, as shown in Figure 2, the user first uses the first adhesive 140 to bond the display module 120 and the backlight module 130. Then, as shown in Figure 3, the user places the connected display module 120 and backlight module 130 into the space SP of the housing 110, and uses the second adhesive 150 to bond the backlight module 130 to the base plate 112 of the housing 110. At this point, the installation of the display device 100 is also completed. Since the installation of the display device 100 is simple and easy, the installation cost can be effectively reduced.

[0032] In summary, the technical solution disclosed in the above embodiments of the present invention has at least the following advantages:

[0033] (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 width of the frame of the display device can be effectively narrowed, thereby improving the practicality and visual effect of the display device.

[0034] (2)Since the installation of the display device is simple and easy, the installation cost can be effectively reduced.

[0035] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements 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 appended claims. [Simplified Explanation of the Diagram]
