Abstract

The invention discloses a manufacturing method of a carbon nano-tube conducting film applied to a capacitive touch screen. The manufacturing method of the carbon nano-tube conducting film applied to the capacitive touch screen comprises the steps that a CAD pattern is guided into a screen-printing machine, a carbon nano-tube is manufactured on a transparent conducting film in a screen printing mode, a series of working procedures of cleaning, drying, curing and ageing are conducted on the carbon nano-tube manufactured on the transparent conducting film, and then cutting is carried out to obtain the final product. The carbon nano-tube conducting film manufactured through the screen printing technology can improve production efficiency, overcome the defects that etching marks are obvious and uneasy to control by a former technology, is improved on the aspects of the signal to noise ratio, IC application, the LCD panel power and the like, and brings a perfect experience to users.

Description

technical field [0001] The invention relates to a method for manufacturing a conductive film, in particular to a method for manufacturing a carbon nanotube conductive film applied to a capacitive touch screen. Background technique [0002] Today, capacitive touch screens have been widely used in many electronic products, making them thinner, easier to carry, and showing a stylish aesthetic, such as mobile phones, tablet computers, GPS navigation and other daily-used products. [0003] Electronic products have higher and higher requirements for touch screens. Touch screens must develop in the direction of flexibility and bendability, improve their adhesion and scratch resistance, and take into account the improvement of light transmittance and electrical conductivity. Realize low square resistance, lower the threshold of IC application, and bring users a more perfect touch screen display.
