Embodiment 1

[0039] Such as figure 1 As shown, the transparent and insulating plastic substrate adopts PET (polyethylene terephthalate) film with high transmittance and low haze, and the pre-dispersed carbon nanotube ink is printed on the first PET substrate according to a predetermined pattern. The surface of the material 2 is printed with positioning marks at the same time, and then dried to form the first transparent conductive electrode pattern; then the conductive silver paste or copper nano-paste tracking positioning mark is overprinted around the first transparent conductive electrode pattern, after drying or sintering The first electrode wires are formed to form the first transparent conductive electrode layer 3 (or called the X-axis direction conductive layer).

[0040] Print the pre-dispersed carbon nanotube ink on the surface of the second PET substrate 4 according to a predetermined pattern, print the positioning mark at the same time, and then dry to form the second transparen...

Embodiment 2

[0049] Such as figure 1 with 4 As shown, the transparent insulating plastic substrate adopts PET (polyethylene terephthalate) film with high transmittance and low haze, and the pre-dispersed carbon nanotube ink is printed on the PET P4 according to the predetermined pattern. On the front side, the positioning mark is printed at the same time, and then dried to form the first transparent conductive electrode pattern; then the conductive silver paste or copper nano-paste tracking positioning mark is overprinted around the first transparent conductive electrode pattern, and the second transparent conductive electrode pattern is formed after drying or sintering. An electrode wire is made into the first transparent conductive electrode surface P3 (or called the X-axis direction conductive surface).

[0050] Then trace the pre-dispersed carbon nanotube ink to the positioning mark on the first transparent conductive electrode layer and print it on the reverse side of PET P4 to align...

Abstract

The invention provides a flexible transparent touch membrane which can be mounted or pasted on any display interfaces, the display interface can be planar and curved, can be used as a display wall, and can realize interactive touch function. Compared with the traditional touch screen, the flexible transparent touch membrane provided by the invention is light in weight and low in cost, can be mounted and exchanged at ease, can be bent due to the flexibility of the membrane, is not confined by processing size, while being combined with a future flexible display, a wide touch application space is provided, and the touch membrane can be applied in a new field and can be used on a large scale.

Description

technical field [0001] The invention relates to the technical field of touch interaction, in particular to a flexible transparent touch film. Background technique [0002] At present, the touch screen is a good human-computer interaction tool to replace the mouse, but the existing traditional touch screen technology is mostly made of glass substrates, which is limited to the application of mobile phone panels and small industrial control panels, and it is not possible to mass-produce touch screens larger than 10 inches at low cost. , It is impossible to realize mass production of large-size touch screens. At present, the homogeneity of small and medium-sized touch panels in the industry is serious, the manufacturing yield is low, and the constraints of process technology keep the cost high. [0003] At present, most large-size touch screens are made of infrared technology, acoustic wave screens, and photoelectric screens. The cost of ultrasonic and infrared generation and d...
