Abstract

The invention discloses a touch panel. The touch panel is provided with a touch area; the touch panel comprises a transparent substrate, a touch electrode and a first transmission line, wherein at least one conductive hole is formed in the transparent substrate; the touch electrode is laid on the front surface of the transparent substrate and positioned in the touch area; and the first transmission line is laid on the back surface of the transparent substrate and electrically connected with the touch electrode through the conductive hole. According to the touch panel, by arranging at least part of the transmission line, that is laid on the transparent substrate, on the other side surface opposite to the touch electrode, the wiring flexibility of the transmission line can be improved; and in addition, the touch panel has the advantages and effects of reducing the wiring area of the touch panel and expanding the touch area of the touch panel.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch panel. Background technique [0002] An example of an existing touch panel structure is figure 1 As shown, it includes: a transparent substrate 10, a touch electrode 20 arranged on the surface of the transparent substrate 10, and a transmission line 23 (trace) electrically connected to the touch electrode 20; the touch electrode 20 is usually made of a transparent conductive oxide film material (Usually use indium tin oxide ITO) to form a certain pattern of touch electrodes 20 through coating etching. The touch electrodes 20 include a plurality of sensing units 21 (sensors) evenly distributed on the surface of the transparent substrate 10 Connecting wires 22 between measuring units 21. [0003] Taking the existing capacitive touch panel as an example, the capacitive touch panel works by using the current induction between the human body and the sensing electrodes 20 . W...
