Problems solved by technology

[0003] However, when making this type of touch screen, it is difficult to form the touch electrodes on the polarizer because the polarizer is generally made of colloidal material, and the touch electrode (ITO) is a high-temperature process.
This is because: if high temperature is used, the polarizing plate may be damaged, and if low temperature is used, the touch electrode cannot be formed on the polarizing plate well.

Embodiment 1

[0040] figure 1 A flow chart of the manufacturing method of the touch screen provided by Embodiment 1 of the present invention is shown. see figure 1 , the touch screen manufacturing method provided by Embodiment 1 of the present invention includes the following steps:

[0041] Step 101: attaching the transparent conductive layer on the polarizer through a transfer printing process.

[0042] Step 102: Patterning the transparent conductive layer by patterning process, so that a plurality of touch electrodes are formed on the polarizer to obtain a touch screen.

[0043] In this embodiment, the transparent conductive layer may be made of ITO.

[0044] In this embodiment, the transparent conductive layer is attached to the polarizer through a transfer printing process, which can not only ensure good adhesion between the transparent conductive layer and the polarizer, but also ensure that the polarizer is not damaged. Since the polarizer is generally made of colloidal material,...

Embodiment 2

[0046] Embodiment 2 of the present invention provides an implementation manner of attaching the transparent conductive layer on the polarizer through the transfer printing process in the above step 101 .

[0047] In this example, see figure 2 , the step 101 attaches the transparent conductive layer to the polarizer through a transfer printing process, specifically including:

[0048] Step 101: Attach the transparent conductive layer on the polarizer by applying pressure to the transparent conductive layer under preset heating conditions.

[0049] see image 3 , in this embodiment, a specific implementation method of attaching the transparent conductive layer to the polarizer by applying pressure to the transparent conductive layer under preset heating conditions in step 101 is also given. , including:

[0050] Step a: spread the transparent conductive layer on the polarizer.

[0051] Step b: Rolling and pressing the transparent conductive layer with a lamination roller wi...

Embodiment 3

[0065] In the above-mentioned embodiment 2, an implementation method of attaching the transparent conductive layer to the polarizing plate through the transfer printing process in step 101 has been given, that is, under preset heating conditions, by applying pressure to the transparent conductive layer The transparent conductive layer is pasted on the polarizer.

[0066] In addition, the above-mentioned embodiment 2 also provides an embodiment in which the transparent conductive layer is attached to the polarizer by rolling and applying pressure.

[0067] Different from rolling pressure in the second embodiment, this embodiment provides an implementation manner in which the transparent conductive layer is attached to the polarizer by plane pressure.

[0068] see Figure 5 , in this embodiment, under preset heating conditions, the transparent conductive layer is attached to the polarizer by applying pressure to the transparent conductive layer, specifically including:

[0069...

Abstract

The invention provides a method for manufacturing a touch screen, a touch screen and a display substrate. The method for manufacturing a touch screen includes: attaching a transparent conductive layer on a polarizing plate through a transfer printing process; patterning the transparent conductive layer by using a patterning process, A plurality of touch electrodes are formed on the polarizer to obtain a touch screen. The manufacturing method of the touch screen provided by the present invention adopts the transfer printing process, so it can achieve a better adhesion effect between the touch electrodes and the polarizing plate under the premise of ensuring that the polarizing plate is not damaged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a manufacturing method of a touch screen, a touch screen and a display substrate. Background technique [0002] An existing type of touch screen is to directly form the touch electrodes on the polarizer. This type of touch screen can save a layer of glass substrate because the polarizer is used instead of the glass substrate, so that the entire display substrate is light and thin. At the same time, it also saves a certain amount of cost, so the application prospect of this type of touch screen is better. [0003] However, when manufacturing this type of touch screen, it is difficult to form the touch electrodes on the polarizer because the polarizer is generally made of colloidal material, and the touch electrodes (ITO) are processed at a high temperature. This is because: if high temperature is used, the polarizer may be damaged, and if low temperature is used, the touch elect...
