Transparent conductive film, conductive oil and touch panel

Abstract

The invention provides a transparent conductive film. The transparent conductive film comprises a transparent substrate, a dielectric layer and a conductive layer. The dielectric layer is arranged on the transparent substrate in a stacked mode, the conductive layer is arranged in the dielectric layer in an embedded mode, and the conductive layer is a metal mesh layer. The conductive layer is formed by sintering conductive ink containing metal particles and dark color additive particles. The dark color additive particles are used for shielding light reflected by the metal particles. The transparent conductive film has the good visual effect. The invention further provides the conductive ink for making the conductive layer and a touch panel comprising the transparent conductive film.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a transparent conductive film, conductive ink and a touch panel. Background technique [0002] The transparent conductive film is a kind of conductive film with good conductivity and high light transmittance in the visible light band. At present, transparent conductive films have been widely used in fields such as flat panel displays, photovoltaic devices, touch screens, and electromagnetic shielding, and have an extremely broad market space. The material for preparing the conductive film is generally indium tin oxide (IndiumTinOxide, ITO), but in most practical applications such as touch panels, the preparation of the conductive film needs to pattern the ITO to form a fixed conductive area on the surface of the substrate and Insulated area. However, the patterning process of ITO often requires multiple processes such as exposure, imaging, etching, and cleaning, and the preparat...

Problems solved by technology

Because the metal has a certain luster, the conductive film prepared is easy to be seen by the naked eye due to the reflective effect of the metal, thus affecting the visual effect of the conductive film.
