For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0025] like Figure 1 As shown, a narrow-frame display device includes:

[0026] The device housing 100 includes an upper housing 110 and a lower housing 120 which are relatively assembled, an assembly cavity is formed between the upper housing 110 and the lower housing 120, and the upper housing 110 includes a housing top surface 111, and a window opening is opened on the housing top surface 111;

[0027] The display module 200 is arranged in the assembly cavity of the device housing 100 and exposed from the window opening, and includes a display panel 210 and a module bracket 220. The display panel 210 is arranged in the module bracket 220. The module bracket 220 includes a bracket bottom surface 222 and a bracket side wall 221. The bracket side wall 221 is connected to the periphery of the bracket bottom surface 222. An inner fixing area and an outer fixing area are formed on the top end surface of the bracket side wall 221. The outer fixing area of ​​the module bracket 220 is adhesively fixed to the housing top surface 111.

[0028] The protective cover 300 is disposed in the window opening of the device housing 100 , and its periphery is bonded and fixed to the inner fixing area of ​​the module bracket 220 .

[0029] The display device of the present invention adheres and fixes the module bracket 220 of the display module 200 to the protective cover 300 and the device casing 100 respectively, so that the protective cover 300 is indirectly fixed to the device casing 100 through the display module 200, and the periphery of the protective cover 300 only needs to extend to the inner fixing area of ​​the module bracket 220, and does not need to extend to the casing top surface 111 of the upper casing 110. In this way, the size of the protective cover 300 can be made smaller than the size of the display module 200. When the size of the display module 200 remains unchanged, the outer peripheral frame of the protective cover 300 can be reduced to achieve the narrow frame effect of the protective cover 300.

[0030] like Figure 2 As shown, the display panel 210 includes a display area and a non-display area, and the non-display area surrounds the periphery of the display area; the protective cover 300 includes a light-transmitting area 310 and a frame area 320, and the frame area 320 surrounds the periphery of the light-transmitting area 310; the light-transmitting area 310 of the protective cover 300 corresponds to the display area of ​​the display panel 210, and the frame area 320 of the protective cover 300 corresponds to the non-display area of ​​the display panel 210 and the internal fixing area of ​​the module bracket 220.

[0031] In the present invention, the outer frame of the protective cover 300 refers to the frame area 320, and the outer periphery of the protective cover 300 refers to the local area of ​​the frame area 320 that is bonded and fixed to the module bracket 220, that is, the outer circle of the frame area 320. The frame area 320 is used to shield the non-display area of ​​the display panel 210. In the prior art, the frame area 320 of the protective cover 300 extends to the top surface 111 of the housing and is bonded and fixed to the top surface 111 of the housing, while in the present invention, the frame area 320 of the protective cover 300 only extends to the inner fixed area of ​​the module bracket 220, and the width of the frame area 320 is greatly reduced.

[0032] Generally speaking, the border area 320 of the protective cover 300 is a shading area, and BM ink is silk-screened on the side facing the display module 200. However, under certain special visual requirements for appearance, the border area 320 of the protective cover 300 can also be a semi-transparent area or a luminous area, etc.

[0033] The upper housing 110 and the lower housing 120 adopt a split assembly structure or an integrated assembly structure. Before assembly, the upper housing 110 and the lower housing 120 are separated from each other; during assembly, the display module 200 needs to be assembled into the upper housing 110 from the bottom opening of the upper housing 110, and the outer fixing area of ​​the module bracket 220 is bonded and fixed to the housing top surface 111 of the upper housing 110, and then the top opening of the lower housing 120 is arranged opposite to the bottom opening of the upper housing 110 for assembly and fixing, so as to form the device housing 100.

[0034] The split assembly structure between the upper housing 110 and the lower housing 120 means that the upper housing 110 and the lower housing 120 are assembled and fixed by means of snap connection, magnetic connection or glue bonding, etc., and this kind of assembly and fixing method can later disassemble and separate the upper housing 110 and the lower housing 120. The integrated assembly structure between the upper housing 110 and the lower housing 120 means that the upper housing 110 and the lower housing 120 are assembled and fixed by means of heating welding, ultrasonic welding, etc., and this kind of assembly and fixing method cannot later disassemble and separate the upper housing 110 and the lower housing 120.

[0035] In this embodiment, the outer fixing area of ​​the module bracket 220 and the casing top surface 111 of the upper casing 110 , as well as the periphery of the protection cover 300 and the inner fixing area of ​​the module bracket 220 are bonded and fixed by means of structural adhesive 400 .

[0036] Specifically, the upper shell 110 also includes a first shell side wall 112, and the first shell side wall 112 is connected to the periphery of the shell top surface 111; the lower shell 120 includes a shell bottom surface 121 and a second shell side wall 122, and the second shell side wall 122 is connected to the periphery of the shell bottom surface 121; the upper shell 110 and the lower shell 120 are relatively assembled and connected through the first shell side wall 112 and the second shell side wall 122.

[0037] In order to improve the stability between the display module 200 and the device casing 100, a plurality of screw columns 223 are provided on the side of the bracket bottom surface 222 facing the casing bottom surface 121, and a plurality of screw holes 130 are provided on the side of the casing bottom surface 121 facing the bracket bottom surface 222. One screw column 223 corresponds to one screw hole 130, and the corresponding screw columns 223 and screw holes 130 are fixed by locking screws (not shown in the figure).

[0038] Preferably, a buffer ring 600 is provided between the corresponding screw column 223 and the screw hole 130 , and the buffer ring 600 may be, but is not limited to, a silicone ring or a rubber ring or other elastic material.

[0039] If the display panel 210 is an LCD panel, the display module 200 further includes a backlight module (not shown in the figure), and the backlight module is disposed between the display panel 210 and the bottom surface 222 of the bracket.

[0040] The display module 200 further includes a driving mainboard 230 . The driving mainboard 230 is disposed on a side of the bracket bottom surface 222 facing the housing bottom surface 121 , and is electrically connected to the display panel 210 via a flexible circuit board.

[0041] In this embodiment, the protection cover plate 300 and the display panel 210 are bonded and fixed by transparent optical adhesive 500 .
