Based on the same concept of the touch module, this embodiment further provides a method for manufacturing a touch module, as shown in fig. 4, including the following steps:
1) forming a plurality of first bridges 111 of a touch electrode structure on the manufactured display substrate 200; the display substrate 200 may include a plurality of sub-pixel units. Specifically, the electrode material may be deposited on the display substrate 200 in a whole layer, and then the whole layer is patterned to obtain the first bridge member 111.
2) A plurality of first color sub-color film layers of a color filter structure are formed on the display substrate 200, and a portion of each first color sub-color film layer is used as an insulating layer to cover the first bridge member 111. Specifically, a full color film layer may be formed on the display substrate 200, and then the full color film layer may be patterned to obtain a sub-color film layer with a first color. In general, the sub-color film layer of the first color may completely cover the first bridge member 111, and then the electrical conduction between the first bridge member 111 and the first electrode unit 112 is achieved through the via hole 211. However, the pixel resolution of the sub-color film layer of the first color (green in the present application) is not required, and it is difficult to form the via hole 211 or the via hole 211, the sub-color film layer 21 of the green color may only cover the bridge portion of the first bridge 111, and the connection portion of the first bridge 111 is exposed, so that the first bridge 111 is connected to the first electrode unit 112.
3) Forming a first electrode 11 and a second electrode 12 of a touch electrode structure on the first sub-color film layer, wherein the first electrode and the second electrode are respectively arranged in a plurality of rows and columns; wherein each first electrode 11 includes a plurality of first electrode units 112, each second electrode 12 includes a plurality of second electrode units 121, each adjacent two first electrode units 112 are connected by a first bridge member 111, each adjacent two first electrode units 112 are connected by a second bridge member, and the first bridge member 111 and the second bridge member intersect each other and form a space in a direction perpendicular to the display substrate 200, and a portion of the sub-color film layer of the first color is disposed within the space as an insulating layer. Specifically, an electrode layer may be deposited on the display substrate 200 by using an electrode material, and then the entire film layer may be patterned by using a mask with a suitable opening, so as to obtain the touch electrode structure.
4) A plurality of sub-color film layers of the second color and a plurality of sub-color film layers of the third color of the color film structure are formed on the display substrate 200, and the sub-color film layers of the first color, the sub-color film layers of the second color and the sub-color film layers of the third color are sequentially and cyclically arranged and are arranged in one-to-one correspondence with the sub-pixel units. Specifically, referring to the manufacturing process of the green sub-color film layer 21, the entire red film layer (or the entire blue film layer) is firstly formed on the display substrate 200, then the red sub-color film layer 22 (or the blue sub-color film layer 23) is formed by patterning, and then the blue sub-color film layer 23 (or the red sub-color film layer 22) is formed by using a similar process.
It should be noted that the process adopted in each step is only one embodiment of the present embodiment, and is not limited to the present application, and any specific process may be adopted as long as the above manufacturing method can be realized.
5) The black matrix 30 is formed on the touch electrode structure, and the projection of the black matrix 30 on the plane parallel to the display substrate 200 completely covers the projection of the touch electrode structure on the plane parallel to the display substrate 200, so as to enhance the light shielding effect on the touch electrode structure.
6) Forming a planarization layer 40 on the color film structure, and making the planarization layer 40 completely cover the black matrix 30 (if there is no black matrix 30, the color film structure is completely covered), and the projection on the display substrate 200 completely covers the projection of the color film structure on the display substrate 200, so as to perform subsequent processes on the touch module.
In one embodiment, the first color comprises green, the second color comprises red, and the third color comprises blue, wherein a portion of each green sub-color film layer 21 is disposed in the space as an insulating layer.
In one embodiment of the present application, each red sub-color film 22 includes a red filter portion and a red shielding portion, and each blue sub-color film 23 includes a blue filter portion and a blue shielding portion; forming a plurality of sub-color film layers of a second color and a plurality of sub-color film layers of a third color of a color film structure on the display substrate 200, further comprising the following steps: a red color sub-film layer 22 and a blue color sub-film layer 23 are formed on the display substrate 200, and the red filter portion, the green color sub-film layer 21 and the blue filter portion are sequentially arranged on the display substrate 200, so that the red light-shielding portion and the blue light-shielding portion are overlapped on the touch electrode structure, and the projection of the red light-shielding portion and the blue light-shielding portion on the plane parallel to the display substrate 200 completely covers the projection of the touch electrode structure on the plane parallel to the display substrate 200. Because the transmittances of the red sub-color film layer 22 and the blue sub-color film layer 23 are complementary in a 380nm-780nm waveband, the light shielding effect on the touch electrode structure can be realized through the superposition of the red light shielding part and the blue light shielding part, so that the transmission of ambient light is reduced, and the influence of the reflection of the touch electrode structure on light on the display effect is prevented. Therefore, when the light shielding effect of the red light shielding portion and the blue light shielding portion in superposition can be equivalent to the black matrix 30, the black matrix 30 can be omitted.
The touch module manufactured by the manufacturing method provided by the embodiment includes a color film structure and a touch electrode structure, the color display effect can be enhanced by setting the color film structure, the intersection of the first electrode 11 and the second electrode 12 of the touch electrode structure has a gap in the direction perpendicular to the display substrate 200, that is, the intersection of the first electrode 11 and the second electrode 12 is realized in a bridging manner, and a part of the sub-color film layer of at least one color is used as an insulating layer to be arranged in the gap.
