Abstract

A touch panel, a manufacturing method thereof and a display device are disclosed. The touch panel includes a first sensing layer (10) and a second sensing layer (11) which are superimposed. The first sensing layer includes a plurality of columns of first sensing lines (12); each first sensing line is formed by the alternate series connection between first transparent electrodes (1) and first metal wires (2); the second sensing layer includes a plurality of rows of second sensing lines (34); each second sensing line is formed by the alternate series connection between second transparent electrodes (3) and second metal wires (4); in terms of vertical projections of the first sensing layer and the second sensing layer on a plane of the touch panel, the first transparent electrodes (1) and the second transparent electrodes (3) are alternately arranged along the column direction and the row direction; the first metal wires (2) and the second metal wires (4) are alternately arranged along the column direction and the row direction; the first metal wire (2) crosses over the second transparent electrode (3); and the second metal wire (4) crosses over the first transparent electrode (1). The touch panel can solve the Moiré problem.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch screen and a manufacturing method thereof. Background technique [0002] In the touch screen industry, the practice of using metal grids as touch drive lines and sense lines is widely used. Compared with indium tin oxide, the metal grid has become a research hotspot for technicians in the field because of its faster signal transmission speed. However, there are many problems in the application of the metal grid in the touch screen, especially the moiré problem is the most difficult to solve. [0003] In the prior art, the moiré problem is usually solved by reducing the line width of the metal lines. However, reducing the line width of the metal line will increase the difficulty of the manufacturing process and increase the production cost, and reducing the metal line width to a very low level will easily cause problems such as breakage of the metal line and poor anti-static...
