Problems solved by technology

The main purpose of said patent case is to reduce the b of the penetration chromaticity of the transparent conductive film 1 * , in order to achieve the effect that the transparent conductive film does not appear yellow, but in this case, the inventor prepared the transparent conductive film according to the content of the patent case, and tested it after patterning the indium tin oxide (ITO) layer. Compared with the reflected light emitted from the non-patterned portion of the transparent conductive film, the difference in reflectivity between the two reflected lights is still too large, so it is difficult for users to see when viewing the touch panel. As far as the traces of the patterned transparent conductive layer are concerned, the transparent conductive film of the said patent obviously does not meet the requirements
[0005] Based on the above, it is still necessary to improve the conductive transparent laminate to solve the problem that the user is easy to see the traces of the patterned transparent conductive layer when viewing, so as to improve the display quality of the touch panel

preparation example Construction

[0028] The preparation method of the conductive transparent laminate of the present invention comprises the following steps: providing a transparent substrate, forming an optical adjustment layer with a refractive index ranging from 1.33 to 1.52 at a wavelength of 400 nm on the transparent substrate to obtain a first laminate. A metal oxide layer is then formed on the optical adjustment layer to obtain a second laminated body. Then, the metal oxide layer of the second laminate is crystallized and annealed to obtain a transparent conductive layer (the carrier concentration range is 10×10 21 piece / cm 3 up to 20×10 21 piece / cm 3 ), that is, the conductive transparent laminate of the present invention is obtained.

[0029] The method of forming the optical adjustment layer on the transparent substrate is not particularly limited, and existing methods can be used, for example, dry coating method, wet coating method and the like can be used. In terms of production efficiency and...

Description

technical field [0001] The present invention relates to a conductive transparent laminate applied to a touch panel, in particular to a conductive transparent laminate comprising an optical adjustment layer in contact with a transparent substrate with a refractive index ranging from 1.33 to 1.52 and a physical thickness ranging from 10nm to 30nm. Transparent laminate. Background technique [0002] In order to improve the quality of the touch panel, the conductive transparent laminate currently used in the touch panel includes a transparent substrate, a transparent conductive layer (transparent conductive layer), and several optical layers arranged between the transparent substrate and the transparent conductive layer. The adjustment layer adjusts the total light transmittance and penetrating color of the conductive transparent laminate by regulating the refractive index and thickness of the optical adjustment layer, thereby improving the screen brightness of the touch panel a...
