Problems solved by technology

Due to the requirements of touch resolution, there are a certain number of metal wires arranged in the circuit area, and the adjacent metal wires must have a certain distance limited by the process limit to ensure electrical insulation from each other. Therefore, the circuit of the touch panel The area of ​​the region will be limited by the number of metal wires and cannot be further reduced
As a result, it is not conducive to the design of maximizing the touch sensing area

Abstract

The invention discloses a capacitive touch panel and a manufacturing method thereof. The capacitive touch panel comprises a substrate, multiple sensing electrodes, multiple strips of signal guide wires and a patterned insulating layer. The sensing electrodes are arranged on the substrate and electrically insulated with one another. Each signal guide wire is electrically connected to a sensing electrode in a one-to-one corresponding mode. At least one part of the signal guide wires and at least one part of the sensing electrodes are overlapped and insulted in a vertical projection direction. The patterned insulating layer is arranged between at least one part of the signal guide wires and the at least one part of the sensing electrodes.

Description

technical field [0001] The invention relates to a capacitive touch panel and a manufacturing method thereof, in particular to a capacitive touch panel capable of maximizing the effective touch area and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development of touch sensing technology, many consumer electronic products such as mobile phone, GPS navigator system, tablet PC and laptop PC ) and so on are matched with a touchpad to provide a touch function. A traditional touch panel can be divided into a touch sensing area and a circuit area located around it according to the working area, wherein a plurality of sensing electrodes arranged in two axial directions and intersecting are arranged in the touch sensing area, and the circuit area Metal wires for transmitting touch signals are disposed inside, and each metal wire is connected in series to a plurality of sensing electrodes. Due to the requirements of touch resolution, t...
