Embodiment 1

[0045] refer to figure 2 , shows a cross-sectional view of a touch display module according to an embodiment of the present invention.

[0046] The present invention provides a touch display module, including: a display module and a touch panel 204, and the display module includes a display panel 201, a first polarizer 202, and an adhesive component 203;

[0047] Wherein, the first adhesive portion 2031 of the adhesive member 203 and the first polarizer 202 are located on the light emitting side of the display panel 201, and the orthographic projection of the first adhesive portion 2031 of the adhesive member 203 on the display panel 201 is the same as that of the first polarizer 202. There is no overlapping area in the orthographic projection of a polarizer 202 on the display panel 201;

[0048] The touch panel 204 is fixedly connected to the first polarizer 202 in the display module through the first optical glue 205, and the orthographic projection of the first optical gl...

Embodiment 2

[0082] An embodiment of the present invention includes a display device, including the above-mentioned touch display module.

[0083] For the specific description of the touch display module, reference may be made to the description of Embodiment 1, which will not be repeated in this embodiment of the present invention.

[0084] The display device also includes devices such as a touch driver chip and a display driver chip.

[0085] In the embodiment of the present invention, the display device is a touch display device, and the display device may be any narrow-frame product or component with display and touch functions, such as a mobile phone, a tablet computer, a television, a notebook computer, and a vehicle display product.

[0086] In the embodiment of the present invention,

[0087] By forming the first optical glue on the first polarizer, the orthographic projection of the first optical glue on the first polarizer is located inside the area where the first polarizer is ...

Embodiment 3

[0089] refer to Figure 5 , which shows a flow chart of a manufacturing method of a touch display module according to an embodiment of the present invention, which may specifically include the following steps:

[0090] Step 510, providing a display module; the display module includes a display panel, a first polarizer and an adhesive component.

[0091] In an embodiment of the present invention, a display module is provided, the display module includes a display panel 201, a first polarizer 202 and an adhesive component 203, the display panel 201 includes a color filter substrate, an array substrate, and a display panel between the color filter substrate and the array substrate. In the liquid crystal layer between the substrates, the first polarizer 202 is located on the side of the color filter substrate in the display panel 201 away from the liquid crystal layer, wherein the first adhesive part 2031 of the glued part 203 and the first polarizer 202 are both located on the si...

Abstract

The invention provides a touch display module, a manufacturing method thereof and a display device, and relates to the technical field of display. The touch display module comprises a display module and a touch panel. The display module comprises a display panel, a first polaroid and a gluing part; first optical cement is formed on the first polaroid; the orthographic projection of the first optical cement on the first polaroid is located in the area where the polaroid is located; therefore, a problem that bubbles are generated because the gap between the first polaroid and the first bonding part of the gluing part is not filled with the first optical cement completely is solved. The yield rate is improved. Besides, a first shading layer is formed on the side, facing the display panel, ofthe touch panel, the first shading layer makes contact with the first optical cement part, the width of the contact area is made to be larger than or equal to a set threshold value, so that the adhesive edge of the first optical cement can be shaded, and the bright line problem generated by the adhesive edge of the first optical cement under the large viewing angle is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display module, a manufacturing method thereof, and a display device. Background technique [0002] Since the narrow bezel display module can bring better experience to people, such as a larger field of vision, people's demand for the narrow bezel display module is getting higher and higher. [0003] At present, adhesive tape is used to replace the front frame in the touch display module to achieve narrow borders. The display module and the backlight in the touch display module are fixed together by adhesive tape. The edge of the polarizer is aligned and pasted on the glass substrate on the light-emitting side of the display panel. [0004] In the prior art, when the tape is used to fix the display module and the backlight, the production line operation cannot ensure that the tape and the polarizer are in close contact, and there will be a gap of about 0.3 mm in...
