Detailed Description

The present invention will be described in further detail with reference to the drawings and the detailed description, and the same symbols in different drawings can represent the same components, but the present invention is not limited thereto.

Please refer to fig. 1 and fig. 2, which are schematic side views of a touch display module according to a first embodiment of the present invention. The touch display module 100 of the present embodiment mainly includes an integrated frame 200, a backlight module 300, a thin film transistor substrate 410, a color filter 420, and a polarizer 430. The integrated housing 200 has a bottom plate 210 and a side plate 220, and the side plate 220 is erected on the bottom plate 210. The backlight module 300 is disposed on the bottom plate 210 and in the space surrounded by the side plate 220. As shown in fig. 2, the backlight module 300 mainly includes a light source 310, a light guide plate 320, a reflective sheet 330 and an optical film 340. The light source 310 is disposed adjacent to one side of the light guide plate 320, the reflective sheet 330 is disposed below the light guide plate 320, and the optical film 340 is disposed above the light guide plate. Thus, the light generated by the light source 310 can enter from the side of the light guide plate 320 and exit from the front of the light guide plate 320, the reflective sheet 330 can reflect the light exiting from the bottom of the light guide plate 320 back to the light guide plate 320, and the optical film 340 can homogenize the light exiting from the light guide plate 320. In some examples, the light source 310 may be a light emitting diode (led) light bar, and the light source 310 may be fixed in the integrated frame through a double-sided tape or through a limiting groove on the bottom plate portion 210 of the integrated frame. It should be appreciated that the backlight module 300 of the present embodiment does not have an iron case for combining other frame bodies of the conventional backlight module, so that the weight of the entire touch display module 100 can be reduced.

As shown in fig. 1 and 2, the tft substrate 410 is disposed on the backlight module 300. The color filter 420 is disposed on the thin film transistor substrate 410. The polarizing plate 430 is disposed on the color filter 420. One surface of the polarizer 430 is an outer surface of the touch display module 100 of the present embodiment. That is, the touch display module 100 of the present embodiment does not have a cover glass (cover glass) used in the conventional touch display module, but directly uses the surface of the polarizer 430 as a direct operation surface of a user, so that the thickness of the touch display module 100 as a whole can be reduced. Since the touch display module 100 of the present embodiment does not use a protective glass, the polarizer 430 of the present embodiment can be cured to improve the hardness and scratch resistance thereof, thereby protecting the components below the polarizer 430. In one example, the polarizing plate 430 may be surface-treated with silane-modified perfluoropolyether (PFPE).

Referring to fig. 1 and fig. 2 again, in the present embodiment, the backlight module 300 is located in the space surrounded by the side plate portion 220 of the integrated frame 200, and the thin film transistor substrate 410, the color filter 420 and the polarizer 430 are supported on the top surface 221 of the side plate portion 220. The tft substrate 410 of the present embodiment is directly connected to the top surface 221 of the side plate portion 220 of the integrated frame 200. In some examples, the thin film transistor substrate 410 and the color filter 420, the color filter 420 and the polarizer, and the thin film transistor substrate 410 and the top surface 221 of the side plate portion 220 may be adhered to each other through adhesives. Through the structural design of the integrated frame 200, the backlight module 300, the tft substrate 410, the color filter 420 and the polarizer 430 can be integrated together on the same integrated frame 200, so that the overall thickness and weight of the touch display module 100 can be greatly reduced. In addition, the cured polarizer 430 may also protect the backlight module 300, the tft substrate 410 and the color filter 420.

In the embodiment, a light-shielding layer BM is disposed between the color filter 420 and the tft substrate 410 for shielding the light near the edge of each layer structure, thereby avoiding light leakage. In one example, the light-shielding layer BM may be a black ink layer formed on the bottom surface of the color filter 420 near the edge by printing, and after the light-shielding layer BM is formed on the bottom surface of the color filter 420, the bottom surface of the color filter 420 and the surface of the light-shielding layer BM may be coated with an adhesive, such that the adhesive is completely distributed on the bottom surface of the color filter 420. In other examples, the light-shielding layer BM may be disposed on the upper surface of the color filter 420 or the bottom surface of the tft substrate 410 to achieve the same light-shielding effect. As shown in fig. 1, in some embodiments, the bottom plate portion 210 of the integrated frame 200 has a recess 211, and a buffer 211a may be disposed in the recess 211, where the buffer 211a mainly provides a supporting force for each layer of film inside the integrated frame 200 to ensure uniform light mixing.

In the present invention, the thin film transistor substrate and the color filter can be disposed on the integration frame body in different ways. Referring to fig. 3, fig. 3 is a schematic side view illustrating a touch display module according to a second embodiment of the present invention. The structure of the touch display module 500 of the present embodiment is substantially the same as the touch display module 100 of fig. 1, except that the tft substrate 510 of the touch display module 500 and the backlight module 300 are disposed in the space surrounded by the side plate 220 of the integrated frame 200. As shown in fig. 3, the size of the tft substrate 510 of the touch display module 500 is smaller than the size of the color filter 420 and the polarizer 430, so that the tft substrate and the backlight module 300 can be disposed together in the space surrounded by the side plate 220 of the integrated frame 200. In addition, the color filter 420 and the polarizer 430 are supported on the top surface 221 of the side plate portion 220 of the integrated frame 200. The color filter 420 of the present embodiment is directly connected to the top surface 221 of the side plate portion 220 of the integrated frame 200. Therefore, through the design of the integrated frame 200, the backlight module 300, the tft substrate 510, the color filter 420 and the polarizer 430 can be integrated together on the same integrated frame 200. In the embodiment, the bottom surface of the color filter 420 is provided with a light-shielding layer BM for shielding the light emitted from the edge of the backlight module 300 to avoid light leakage. In other examples, the light-shielding layer BM may be disposed between the color filter 420 and the polarizer 430 to achieve the same light-shielding effect.

In the present invention, the integrated frame body can have different structural designs. Referring to fig. 4, fig. 4 is a schematic side view illustrating a touch display module according to a third embodiment of the present invention. The structure of the touch display module 600 of the present embodiment is substantially the same as the touch display module 100 of fig. 1, except that the integrated frame 610 of the touch display module 600 has a different structural design. As shown in fig. 4, the integrated frame 610 includes a bottom portion 611 and a side portion 612, wherein the side portion 612 has a first step portion 612a and a second step portion 612b, and the second step portion 612b is higher than the first step portion 612 a. The backlight module 300 is located in the space surrounded by the first step 612 a. The tft substrate 410, the color filter 420 and the polarizer 430 are supported on the top surface 612c of the first step 612a and located in the space surrounded by the second step 612 b. As shown in fig. 4, the tft substrate 410 is directly connected to the top surface 612c of the first step portion 612a of the side plate portion 612. Therefore, through the structural design of the integrated frame 610, the backlight module 300, the tft substrate 410, the color filter 420 and the polarizer 430 can be integrated together on the same integrated frame 610. In addition, the cured polarizer 430 may also protect the backlight module 300, the tft substrate 410 and the color filter 420. In the embodiment, a light-shielding layer BM is disposed between the color filter 420 and the tft substrate 410 for shielding the light emitted from the edge of the backlight module 300 and preventing light leakage. In other examples, the light-shielding layer BM may be disposed between the color filter 420 and the polarizer 430 or disposed on the bottom surface of the tft substrate 410 to achieve the same light-shielding effect. Similarly, in some embodiments, the bottom portion 611 of the integrated frame 610 has a recess 611a, and a buffer 611b can be disposed in the recess 611a, and the buffer 611b can mainly provide a supporting force for each layer of the film inside the integrated frame 610, so as to ensure uniform light mixing.

Referring to fig. 5, fig. 5 is a schematic side view illustrating a touch display module according to a fourth embodiment of the present invention. The structure of the touch display module 700 of the present embodiment is substantially the same as the touch display module 600 of fig. 4, except that the tft substrate 710 of the touch display module 700 is disposed in the space surrounded by the first step portion 612a of the side plate portion 612 of the integrated frame 610 together with the backlight module 300. As shown in fig. 5, the tft substrate 710 of the touch display module 700 is smaller than the color filter 420 and the polarizer 430, and therefore can be disposed in the space surrounded by the first step 612a of the integrated frame 610 together with the backlight module 300. In addition, the color filter 420 and the polarizer 430 are supported on the top surface 612c of the first step 612a and located in the space surrounded by the second step 612 b. The color filter 420 of the present embodiment is directly connected to the top surface 612c of the first step portion 612a of the integrated frame 610. Therefore, through the design of the integrated frame 610, the backlight module 300, the tft substrate 710, the color filter 420 and the polarizer 430 can be integrated together in the same integrated frame 610. In the embodiment, the bottom surface of the color filter 420 is provided with a light-shielding layer BM for shielding the light emitted from the edge of the backlight module 300 to avoid light leakage. In other examples, the light-shielding layer BM may be disposed between the color filter 420 and the polarizer 430 to achieve the same light-shielding effect.

It should be appreciated that, in the embodiment of fig. 4, the sizes of the tft substrate 410, the color filter 420 and the polarizer 430 located in the space surrounded by the second step 612b exactly correspond to the size of the space surrounded by the second step 612 b. Therefore, the outer edges of the tft substrate 410, the color filter 420 and the polarizer 430 can just abut against the inner sidewall of the second step 612 b. When the size of the thin film transistor substrate, the color filter and the polarizer is small and cannot be directly abutted against the inner side wall of the second step part, the thin film transistor substrate, the color filter and the polarizer can be connected to the inner side wall of the second step part through filling glue. For example, as shown in fig. 6, fig. 6 is a schematic side view illustrating a touch display module according to a fourth embodiment of the present invention. In the embodiment of fig. 6, the structure of the touch display module 800 is substantially the same as the touch display module 600 shown in fig. 4, except that the thin film transistor substrate 410 ', the color filter 420 ' and the polarizer 430 ' of the touch display module 800 are connected to the inner sidewall of the second level portion 612b through the filling adhesive a 1.

In the present embodiment, a light-shielding layer BM is disposed at a position close to the outer edge of the bottom of the color filter 420' for shielding the light emitted from the edge of the backlight module 300 to avoid light leakage. In other examples, the light-shielding layer BM may be disposed between the color filter 420 ' and the polarizer 430 ' or disposed on the bottom surface of the tft substrate 410 ' to achieve the same light-shielding effect.

In addition, the tft substrate 910, the color filter 920 and the polarizer 430 are bonded to each other, and then the annular engaging member B1 is sleeved on the outer edges of the tft substrate 910 and the color filter 920. Then, the thin film transistor substrate 910, the color filter 920 and the polarizer 430 are assembled into the integrated frame 610, so that the thin film transistor substrate 910 and the color filter 920 are fastened to the inner sidewall of the second step portion 612B through the annular fastener B1, and the outer edge of the polarizer 430 abuts against the inner sidewall of the second step portion 612B. In the present embodiment, the bottom surface of the tft substrate 910 is provided with a light-shielding layer BM for shielding the light emitted from the edge of the backlight module 300 and preventing light leakage. In other examples, the light-shielding layer BM may be disposed between the color filter 920 and the polarizer 430 or between the color filter 920 and the tft substrate 910 to achieve the same light-shielding effect.
