In addition, according to the actual situation, the optical adhesive 330 may also be injected between the frame 317, the liquid crystal panel 312 and the touch module 320 through the opening O of the frame 317, but the invention is not limited thereto.
Please refer to fig. 8. Fig. 8 is a schematic cross-sectional view illustrating a finished product of the touch display module 300 shown in fig. 1. In the present embodiment, as shown in fig. 8, the touch display module 300 includes a liquid crystal display module 310, a touch module 320, a frame 317 and an optical adhesive 330. The liquid crystal display module includes a backlight unit 311 and a liquid crystal panel 312. The backlight unit 311 has a flexible circuit board 316. The liquid crystal panel 312 is disposed on the backlight unit 311. The touch module 320 is disposed on the liquid crystal display module 310. The frame 317 is disposed on the backlight unit 311, at least partially surrounds and abuts the liquid crystal panel 312, and carries the touch module 320. The liquid crystal panel 312 of the liquid crystal display module 310 has a display surface 312a, the display surface 312a of the liquid crystal panel 312 faces the touch module 320, the touch module 320 has a touch surface 320a, the touch surface 320a of the touch module 320 is far away from the liquid crystal panel 312 of the liquid crystal display module 310, and the display surface 312a and the touch surface 320a are curved surfaces and the curved axes of the curved surfaces are parallel to each other.
Furthermore, the curved display surface 312a has a curvature C1 around the curved axis X1, the curved touch surface 320a has a curvature C2 around the curved axis X2, and the curvatures C1 and C2 of the display surface 312a and the touch surface 320a may be at least partially the same or at least partially different from each other. The frame 317 is connected between the touch module 320 and the backlight unit 311 to separate the liquid crystal panel 312 and the touch module 320 from each other. The frame 317 has a break O, and the flexible circuit board 316 at least partially passes through the break O of the frame 317 and is electrically connected to the liquid crystal panel 312. The optical adhesive 330 is filled between the frame 317, the liquid crystal panel 312 and the touch module 320.
In the case of the manufacturing method 100, since the frame 317 is connected between the touch module 320 and the backlight unit 311, and the optical adhesive 330 is filled between the liquid crystal panel 312 and the touch module 320 in an injection manner, the optical adhesive 330 is not easily contacted with the touch module 320 to form uneven defects, and the distance DT between the touch module 320 and the liquid crystal panel 312 can be further effectively reduced, which is helpful for the touch display module 300 to achieve the effect of thinning.
According to actual conditions, the curvature C1 of the display surface 312a and the curvature C2 of the touch surface 320a may be at least partially different, or may be at least partially the same. However, as described above, since the optical adhesive 330 is injected and filled between the frame 317, the liquid crystal panel 312 and the touch module 320, the optical adhesive 330 can be filled between the frame 317, the liquid crystal panel 312 and the touch module 320 no matter the curvature C1 of the display surface 312a is the same as or different from the curvature C2 of the touch surface 320 a. In this way, the curvature C1 of the display surface 312a is not limited by the curvature C2 of the touch surface 320a, so that, in practical operation, a user can make the liquid crystal panel 312 have the display surface 312a with a certain specific curvature C1, and can match the touch module 320 with the touch surface 320a having different curvatures C2, thereby facilitating the production of the touch display module 300 and effectively reducing the production cost of the touch display module 300. It should be noted that the curvature C1 of the display surface 312a and the curvature C2 of the touch control surface 320a may be two-dimensional curvatures or three-dimensional curvatures, that is, the display surface 312a and the touch control surface 320a may be one-dimensional curved surfaces or two-dimensional hyperboloids according to actual situations.
