Problems solved by technology
However, the irregularly distributed spherical spacers 110 will affect the alignment and support of the touch, thereby reducing the accuracy and quality of the touch.
In addition, there is a problem of poor adhesion between the spherical spacer 110 and the substrates 104 and 108, and it is easy to cause the displacement of the spherical spacer 110 due to long-term use, causing problems in maintaining the gap and affecting the accuracy of touch control.
[0004] In addition, in order to reduce the reflectivity of the touch panel, the known technology generally adds an anti-reflection layer to the panel structure, but the newly added anti-reflection layer and related processes will increase the production cost

Embodiment Construction
[0028] In order to solve the problem of irregular distribution of spherical spacers in the known technology, which affects the alignment and support of touch, the present invention uses ink jet printing technology to form spacers in one embodiment, which can Precisely control the position of the spacer, so that the touch panel has good touch alignment and support (the detailed method of using inkjet printing technology is described in the following chapters). In order to increase the adhesion of spacers formed by inkjet printing technology or other methods, another embodiment of the present invention utilizes self-assembled monolayers (SAMs) that are conductive and can increase adhesion to effectively enhance spacers Adhesion to the substrate.
[0029] The following fit Figure 2A ~ Figure 2H A method for manufacturing a resistive touch panel according to an embodiment of the present invention is described. Please refer to Figure 2A , provide a first substrate 202 such as ...

The invention discloses a touch control panel and a manufacturing method thereof. The touch control panel comprises a first substrate and a second substrate which are opposite, a first conducting layer and a second conducting layer are arranged between the first substrate and the second substrate, a first adhesive layer with conductivity is blanketed on the first conducting layer, a plurality of spacers are arranged between the first adhesive layer and the second conducting layer, wherein at least one of the first substrate and the second substrate can recess after contact to control the touch control panel. In one embodiment, the first adhesive layer with conductivity is a self-assembling layer.
Description
technical field [0001] The present invention relates to a display device, in particular to a touch display device. Background technique [0002] Touch input display breaks through market application restrictions and is widely used in consumer electronics products, such as personal digital assistants (PDAs), mobile phones, portable computers, liquid crystal displays, and game consoles, etc., in various portable Under the demand of electronic products, the touch panel has become one of the key components. The advantage of the touch panel is that many light, thin, short, small electronic products with display functions are exempted from large and small buttons and knobs. In this way, the space for buttons and knobs can be omitted, and the omitted space It can be used to provide a larger display space and increase the display area. [0003] Such as figure 1 As shown, in the known touch panel, a plurality of ball spacers 110 (ball spacers) are arranged between the first electr...
