Embodiment Construction

[0048] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. A preferred embodiment of the invention is shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0049] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0050] Unless otherwise d...

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...
