Abstract

The invention relates to a touch panel suitable to be arranged on a display panel, which comprises a substrate, a plurality of first sensing series, a plurality of second sensing series and a plurality of auxiliary line segments. The first and second sensing series comprise a plurality of sensing pads, a plurality of first connecting lines and a plurality of second connecting lines. The pluralityof first connecting lines are parallel with a first direction and are connected in series with a part of sensing pads to form the plurality of first sensing series. The plurality of second connectinglines are parallel with a second direction and are connected in series with other sensing pads to form the plurality of second sensing series. The first sensing pads and the second sensing pads are coplanar, and the first connecting lines are electrically isolated from the second connecting lines. The plurality of auxiliary line segments are positioned in the outline range of the plurality of sensing pads and are directly contacted with the sensing pads.

Description

【Technical field】 [0001] The present invention relates to a touch panel, and in particular to a touch panel with low conductive resistance and good transmittance. 【Background technique】 [0002] Currently, touch panels can be roughly classified into resistive, capacitive, infrared and ultrasonic touch panels, among which resistive touch panels and capacitive touch panels are the most common products. As far as the capacitive touch panel is concerned, the multi-touch feature provides a more user-friendly operation mode, so that the capacitive touch panel is gradually favored by the market. [0003] Figure 1A It is a partial top view diagram of an existing touch panel. Figure 1B It is a schematic cross-sectional view along the line A-A' in Fig. 1. Please also refer to Figure 1A and Figure 1B The touch panel 100 is, for example, a capacitive touch panel, which includes a substrate 110 , a plurality of first sensing series 120 and a plurality of second sensing series 130 ...
