Abstract

The invention relates to a touch panel and a method for determining the ground wire position inside the touch panel. The touch panel comprises a substrate, a drive layer and a sensing layer are sequentially arranged on one side of the substrate, the drive layer comprises a first grounding wire, a second grounding wire and multiple drive electrodes, the sensing layer comprises multiple sensing electrodes, a first capacitor area, a middle capacitor area and a second capacitor area are included between the sensing layer and the drive layer, and the capacitance error between the first capacitor area and the middle capacitor area and the capacitance error between the second capacitor area and the middle capacitor area are both smaller than 2%. According to the touch panel and the method for determining the ground wire position inside the touch panel, the data deviation of the edge point and middle part of a sensor is decreased by means of precise arrangement of a ground wire, and therefore the whole quality of a product is improved.

Description

technical field

[0001] The invention relates to the technical field of touch panels, in particular to a touch panel and a method for determining the position of a ground wire in the touch panel. Background technique

[0002] Currently common electronic products with touch panels include laptop computers, personal digital assistants (PDAs), tablet computers (tablet personal computers), digital cameras, and mobile phones. In actual use, electronic products with touch panels have gradually attracted attention and popularity due to the ability to perform input through fingers, stylus or stylus.

[0003] The touch panel is usually coated with a layer of indium tin oxide film (ITO Layer) and a protective film (Hard Coat Layer) on the surface of the PET film. For the existing touch panel, it is usually necessary to shield all the traces of the ITO channels of the corresponding layer through the ground wire during design, so as to avoid the degradation of the overall quality of the...
