Referring to FIG. 1, FIG. 1 is a flowchart of a first embodiment of a display device assembly method of the present invention, which includes a display module step S1, an assembly step S2, a force application step S3, and a fixing step S4.

The back surface 122 is used to adhere to the display surface 111 of the display panel 11 and has a transparent display area 123 and an opaque non-display area 124 surrounding the display area 123 and in a frame shape. The sticking member 13 is a frame-shaped double-sided tape that is fixed between the non-display area 124 and the display surface 111. An air gap 14 (as shown in FIG. 7) is formed between the display area 123 of the back surface 122 and the display surface 111, and the air gap 14 is located in the range surrounded by the adhesive 13. The transparent plate 12 has two short sides 125 and two long sides 126. The non-display area 124 has two first side portions 127 located on the left and right sides of the display panel 11 and adjacent to the two short sides 125 respectively, and two second side portions 128 located on the upper and lower sides of the display panel 11 and respectively adjacent to the two long sides 126.

In the first embodiment, the light-transmitting panel 12 is an example of a touch panel with touch function. Of course, the light-transmitting plate 12 may also be a protective cover plate that generally does not have a touch function.

Referring to FIGS. 1, 2 and 4, in the assembly step S2, a force applying mechanism 2 is assembled and fixed to the two first side portions 127 (as shown in FIG. 3) and the back side of the display panel 11. The force applying mechanism 2 includes two coupling blocks 21, two structural glues 22, a back coupling piece 23, and two screws 24. Each coupling block 21 has a first end surface 211 and a second end surface 212 opposite to the first end surface 211. The first end surface 211 is recessed toward the second end surface 212 to form a receiving groove 213 for receiving the corresponding structural glue 22. The second end surface 212 is recessed toward the first end surface 211 to form a screw hole 214 for screwing the corresponding screw 24, and the screw hole 214 extends along a front-to-back direction X. The back coupling member 23 of the first embodiment is an example of a back cover, and has a cover 231 for covering the back side of the display panel 11, and two stoppers respectively protruding on the left and right sides of the cover 231板232. The cover 231 has a back plate 233 for abutting against the back 112 of the display panel 11, and two side plates 234 connected to the left and right sides of the back plate 233 vertically, and each side plate 234 is used for abutting against the display panel 11 Corresponds to side 113. Each baffle 232 is vertically connected to the corresponding side plate 234 and is formed with a through hole 235 for the corresponding screw 24 to pass through, and the through hole 235 extends along the front-to-back direction X. Each screw 24 has a screw 241 and a screw head 242 formed at one end of the screw 241.

Referring to Figure 1, Figure 4 and Figure 5, the assembly step S2 includes a first assembly procedure and a second assembly procedure. The first assembly procedure is to connect and fix the two coupling blocks 21 to the two first side portions 127 respectively. First, the liquid structural glue 22 is poured into the accommodating groove 213 of each bonding block 21 and filling the accommodating groove 213 so that each bonding block 21 and the structural glue 22 together form a bonding module 20. Subsequently, each bonding block 21 is cemented through the structural glue 22 The positions of the two bonding blocks 21 are aligned at the appropriate positions on the corresponding first side surface 127. After the structural adhesive 22 is cured, each bonding block 21 is fixed to the corresponding first side surface 127. The structural adhesive 22 of the first embodiment is a structural adhesive with no heavy workability, strong bonding strength and good durability. It can be acrylic structural adhesive or epoxy structural adhesive.

Referring to FIGS. 6 and 7, the second assembly process is to assemble the back coupling member 23 on the back side of the display panel 11 so that the cover 231 covers the display panel 11. At this time, the back plate 233 abuts against the back surface 112, each side plate 234 abuts against the corresponding side surface 113, and each baffle plate 232 faces the second end surface 212 of the corresponding coupling block 21 and is located behind the second end surface 212 in the front-rear direction X, each A gap G is formed between the baffle 232 and the second end surface 212 of the corresponding coupling block 21.

Referring to FIGS. 1, 7 and 8, in step S3, the screw rod 241 of each screw 24 is inserted into the hole 235 of the corresponding baffle plate 232, and the screw head 242 is rotated to lock the screw rod 241 to the corresponding coupling block 21 The screw hole 214. When the screw head 242 of each screw 24 abuts against the rear end of the corresponding baffle 232, it will be stopped by it. At this time, continue to rotate the screw head 242 so that each screw 24 applies a parallel to the front and rear of the corresponding coupling block 21 through the screw 241 Pull force P in direction X. Since a gap G is formed between each baffle 232 and the second end surface 212 of the corresponding coupling block 21, the second end surface 212 of each coupling block 21 will face when each screw 24 exerts a pulling force P on the corresponding coupling block 21 The corresponding baffle 232 approaches. When each coupling block 21 approaches the corresponding baffle 232, a pulling force P is applied to the corresponding first side surface 127 through the structural glue 22 to form a force application end. Since each structural adhesive 22 is separated from the adhesive member 13 by a certain distance, the adhesive member 13 and the display panel to which it is adhered 11 is equivalent to forming a point. The aforementioned force application end generates a torque T rotating around the aforementioned fulcrum on the corresponding first side surface portion 127 to promote the light-transmitting plate 12 to slightly bend and deform in a direction away from the display panel 11. Wherein, the gap G between each baffle 232 and the second end surface 212 of the corresponding coupling block 21 determines the amount of deformation of the light-transmitting plate 12 slightly bent.

In particular, because the two bonding blocks 21 are connected and fixed to the two first side portions 127 through the structural glue 22, and the two first side portions 127 are adjacent to the two short sides 125, each screw 24 can be relatively The pulling force P is applied in a labor-saving manner to pull the corresponding coupling block 21 to move.

In the fixing step S4, when the second end surface 212 of each coupling block 21 touches and is blocked by the front end of the corresponding baffle 232, each screw 24 can no longer rotate and pulls the corresponding coupling block 21 to move. At this time, each screw 24 locks the corresponding baffle 232 and the corresponding coupling block 21 together, so that the transparent plate 12 is fixed in a deformed state as shown in FIG. 8.

Referring to FIG. 9, the assembled display module 1 and the force applying mechanism 2 together constitute a display device 100. The display device 100 of the first embodiment is taken as an example of 21.5 inches. Before the light-transmitting plate 12 is slightly bent and deformed, the thickness of the air gap 14 is about 2 mm or more. By slightly bending and deforming the light-transmitting plate 12 into a deformed state, the thickness of the air gap 14 can be reduced to less than 1 mm, thereby greatly reducing the distance between the back 122 of the light-transmitting plate 12 and the display surface 111 of the display panel 11. Thereby, the influence caused by the excessively large air gap can be overcome to improve the touch and visual effects, and the display device 100 can be made thinner. In addition, the light-transmitting plate 12 is slightly bent and deformed into a deformed state, so that the front surface 121 is curved and has a surface The surface tension. When the front surface 121 of the light-transmitting plate 12 is touched by the user with the finger 3 or is impacted by improper external force, the light-transmitting plate 12 can resist the pressure of the external force to avoid deformation after the force, thereby avoiding the transmission The light plate 12 touches the display surface 111 to form a Newton ring or the touch signal is abnormal. Furthermore, with the design of the force applying mechanism 2, the force can be uniformly applied to a specific position of the light-transmitting plate 12 and its deformation direction can be controlled to be slightly bent and deformed, and the light-transmitting plate 12 can be firmly fixed in a deformed state. In this way, the quality of assembly and manufacturing can be improved.

It should be noted that in other implementation aspects of the first embodiment, the force applying mechanism 2 may also have the following changes: Referring to FIG. 10, the two coupling blocks 21 may also be respectively provided on the two second side surfaces 128, and the back The position of the baffle 232 (as shown in FIG. 2) of the coupling member 23 needs to be adjusted correspondingly according to the position of the coupling block 21 described above.

Referring to FIG. 11, at least one coupling block 21 can be provided on each first side surface portion 127, and at least one coupling block 21 can also be provided on each second side surface portion 128. The coupling block on each first side surface portion 127 in Figure 11 The number 21 is an example of two, and the number of the coupling block 21 on each second side portion 128 is an example. The number and positions of the baffle plates 232 (as shown in FIG. 2) of the back coupling member 23 need to be adjusted correspondingly according to the number and positions of the coupling blocks 21 described above.

Referring to FIG. 12, it is the second embodiment of the assembling method of the display device 200 of the present invention. The assembling method is roughly the same as that of the first embodiment, except for the structure and shape of the back coupling 23.

In the second embodiment, the back joint 23 includes two connecting pieces 236 spaced from the left and right, each connecting piece 236 has a baffle 232, a back plate 233, and a side plate connected between the baffle 232 and the back plate 233 234. In the second assembly procedure of the assembly step S2 (as shown in FIG. 1), the side plate 234 of each connecting piece 236 abuts against the corresponding side surface 113 of the display panel 11, and the back plate 233 abuts against the back surface 112 of the display panel 11. . Subsequently, the back plate 233 is locked to the back surface 112 by a screw 25 to complete the assembly of the connecting piece 236.

Referring to FIG. 13, it is the third embodiment of the assembling method of the display device 300 of the present invention. The assembling method is roughly the same as that of the first embodiment, except for the structure and shape of each coupling block 21 and the back coupling 23.

In the third embodiment, each coupling block 21 has a first block 215 and a second block 216 protruding from the rear end of the first block 215. The first block 215 has a first end surface 211 and a receiving groove 213. The second block 216 is L-shaped and has a second end surface 212 and a screw hole 214. The two baffles 232 of the back coupling 23 are respectively connected to the left and right sides of the back plate 233.

14 and FIG. 15 are the fourth embodiment of the assembling method of the display device 400 of the present invention. The assembling method is roughly the same as that of the first embodiment, except for the structure and shape of each coupling block 21 and the back coupling 23.

In the fourth embodiment, each side plate 234 of the back coupling member 23 is formed with a screw hole 237 for screwing the corresponding screw 24, and the screw hole 237 extends along a left-right direction Y. Each coupling block 21 has a block 217 and a baffle 218 protruding from the rear end of the block 217. The block 217 has a first end surface 211 and a receiving groove 213. The baffle 218 faces the corresponding The side plates 234 are located outside the corresponding side plates 234 in the left-right direction Y, and a gap G is formed between them. The baffle 218 is formed with a through hole 219 which is opposite to the screw hole 237 for the corresponding screw 24 to pass through, and the through hole 219 extends in the left-right direction Y.

In step S3 of applying force (as shown in FIG. 1 ), the screw rod 241 of each screw 24 is inserted into the hole 219 of the corresponding baffle 218, and the screw head 242 is rotated to screw the screw 241 to the screw hole 237 of the corresponding side plate 234. When the screw head 242 of each screw 24 abuts against the corresponding baffle 218, continue to rotate the screw head 242 so that each screw 24 applies a thrust F parallel to the left and right direction Y to the corresponding baffle 218 through the screw head 242 to form a Force end. Since a gap G is formed between each baffle plate 218 and the corresponding side plate 234, each of the baffle plates 218 will approach the corresponding side plate 234 when each screw 24 applies a thrust F to the corresponding baffle plate 218. When each baffle 218 approaches the corresponding side plate 234, the aforementioned force application end generates a torque T rotating around the fulcrum formed by the adhesive 13 and the display panel 11 to which it is adhered to the corresponding first side surface 127 to promote light transmission The board 12 is slightly bent and deformed in a direction away from the display panel 11.

In the fixing step S4, when each baffle 218 touches and is blocked by the corresponding side plate 234, each screw 24 can no longer rotate and push the corresponding coupling block 21 to move. At this time, each screw 24 locks the corresponding baffle 218 and the corresponding side plate 234 together, so that the light-transmitting plate 12 is fixed in the deformed state as shown in FIG. 15.

In summary, the assembling method of each embodiment, through the design of the force applying mechanism 2, can uniformly apply force at a specific position of the light-transmitting plate 12 and control its deformation direction to reduce it. It is bent and deformed, and the light-transmitting plate 12 can be firmly fixed in the deformed state, thereby improving the quality of assembly and manufacturing. In addition, the thickness of the air gap 14 can be reduced to overcome the effects of excessively large air gaps. Furthermore, the front surface 121 of the light-transmitting plate 12 is curved and has surface tension, which can resist external pressure to avoid deformation after being forced. It can indeed achieve the purpose of the invention.
