Abstract

The invention discloses a double-layer touch screen which includes transparent cover plate glass, a first transparent imprint adhesive layer, a first conducting layer, a second transparent imprint layer and a second conducting layer, wherein the first conducting layer is arranged inside the first transparent imprint adhesive layer through insertion and comprises a plurality of conducting bars extending in a first direction, every conducting bar is formed by intersecting conducting filaments, the second conducting layer is arranged inside the second transparent imprint layer through insertion, the second conducting layer includes a plurality of conducting bars extending in a second direction, and every conducting bar is formed by intersecting conducting filaments. Compare with a traditional touch screen, the double-layer touch screen replaces ITO (Indium Tin Oxide) with the first conducting layer and the second conducting layer which are formed by conducting materials filled in a first groove and a second groove, the process does not need extra etching techniques and has relatively low material cost under the premise of guaranteeing the light transmittance and the electrical conductivity, so that the cost is reduced. The invention also discloses a manufacturing method of the double-layer touch screen.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a double-layer touch screen and a preparation method thereof. Background technique [0002] A touch screen is an inductive device that can receive input signals such as touch. The touch screen has given a new look to information interaction and is a very attractive new information interaction device. The development of touch screen technology has aroused the general attention of the information and media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] According to whether each area of ​​the touch screen is transparent, the area coated with the ink layer on the touch screen may be called a non-visible area, and other areas not coated with ink may be called a visible area. The working sensing area of ​​the touch screen is usually set in the visible area. [0004] At present, the ITO (indium tin oxide) layer is a cruci...
