Abstract

The invention relates to a capacitive touch panel. The capacitive touch panel includes at least one first conductive series extending along a first direction and at least one second conductive series extending along a second direction on a substrate. The first conductive series includes a plurality of first electrodes disposed along the first direction and a plurality of first connecting electrodes respectively disposed between two adjacent first electrodes. The second conductive series includes a plurality of second electrodes disposed along the second direction and a plurality of second connecting electrodes respectively disposed between two adjacent second electrodes. The first direction intersects the second direction. At least one kind of elements of the first electrodes, the first connecting electrodes, the second electrodes, and the second connecting electrodes are formed from a metal mash layer, and the first conductive series and the second conductive series are electrically isolated from each other. Thus, the capacitive touch panel achieves effects of being low in impedance and good signal transmission and sensing effects.

Description

technical field [0001] The invention relates to a touch panel, in particular to a capacitive touch panel using a metal mesh layer as a sensing electrode and a manufacturing method thereof. Background technique [0002] In the known capacitive touch panel technology, the material of the transparent sensing electrode is generally formed by indium tin oxide (ITO), because ITO has the characteristics of transparency and conductivity. However, because ITO still has a certain conductive resistance, the ITO layer will produce more obvious impedance problems as the distance increases. If the size of the capacitive touch panel is large, the conduction effect of the transparent sensing electrodes at different positions on the panel It will be uneven. If it is necessary to achieve the effect of reducing impedance, the thickness of the ITO layer must be increased, but a thicker ITO layer will affect the optical effect of the panel. Therefore, when the above-mentioned known technology i...
