Problems solved by technology

However, when the size of the peripheral area of ​​the touch panel is reduced, the routing area of ​​the touch panel is also limited, which reduces the routing space of the routing. Higher precision is required when the ends of the sensing series are lapped, and lapping errors are prone to occur, resulting in poor yield

Abstract

A touch panel, the touch panel divides the connection pads connected in series with sensing electrodes extending in the same direction into two types with different widths, the width refers to the width of the connection pads along the series of sensing electrodes connected to it The length in the extending direction, and the connection pads with a larger width are farther away from the driving circuit than the connection pads with a smaller width, and the connection pads connect the sensing electrode series and the traces so as to be electrically connected to the driving circuit. The touch panel of the present invention can increase the overlapping area of ​​wirings and connection pads located in different layers on the substrate, which facilitates overlapping of wirings and connection pads located in different layers, and improves production yield.

Description

Technical field [0001] The present invention relates to a touch panel and a touch display device. Background technique [0002] In general, to provide input means (pointing device) in the display of the personal digital assistant (PDA), notebook computers, office automation equipment, medical instruments or car navigation systems, the touch panel is used for the above equipment. Common touch panels including resistive type, electromagnetic induction type, an optical type and the capacitive touch panel. Wherein the capacitance (capacitive type) touch panel may be used for the body and the electrostatic capacitance touch position to confirm the changes induced between the transparent electrodes based on the induced current. In order to detect finger or a stylus strokes across the touch position of the touch panel we have been developed a variety of capacitive touch panel technology. [0003] A common capacitive touch panel comprising two mutually orthogonal sensing series, and each...
