Problems solved by technology

However, due to the relationship between the spatial position of the touch panel, the distances between the connecting wires and the controller are different, that is, the lengths of the connecting wires are different, so that the impedance of each connecting wire is different, thereby reducing the sensing accuracy of the touch position.

Abstract

The invention discloses a touch panel comprising a substrate (10), a touch unit array (20), multiple connecting leads (30), an impedance regulation unit (40) and a controller (50). All the touch unit array (20), the connecting leads (30), the impedance regulation unit (40) and the controller (50) are arranged on the substrate (10), the touch unit array (20) is connected to the impedance regulation unit (40) through the leads (30), and the impedance regulation unit (40) is connected to the controller (50) and regulates the impedance of each connecting lead (30) so as to enable all the connecting leads (30) to be identical in impedance. The touch panel has the advantages that the impedance of each connecting lead is regulated to be identical, so that sensing accuracy of the touch panel for the touch positions is improved.

Description

Technical field [0001] The present invention belongs to the technical field of touch panels, and specifically relates to a touch panel capable of adjusting the impedance of connecting wires to be consistent. Background technique [0002] The touch panel is an input device that allows the user to use a finger or an object to input the user's instruction by selecting the instruction content displayed on the screen of an image display or the like. The user's hand or object directly contacts the touch panel at the contact position. Since this touch panel can replace an independent input device such as a keyboard or a mouse connected to the image display, its application field has been expanding day by day. [0003] According to the working principle of touch panels, touch panels can be divided into four types, which are resistive touch panels, capacitive touch panels, infrared touch panels, and surface acoustic wave touch panels. In recent years, capacitive touch panels with multi-to...
