Abstract

A touch panel, including a substrate, a first electrode structure, a second electrode structure, and an insulating layer. The first electrode structure includes first electrode units and second electrode units, wherein each first electrode unit extends in a first direction, each second electrode unit extends in a second direction, and the first electrode units interlace the second electrode units. The first electrode structure is configured between the second electrode structure and the substrate. The insulating layer is configured between the first electrode structure and the second electrode structure to electrically insulate the first electrode structure from the second electrode structure. In a first touch mode, the second electrode structure does not perform a touch sensing function, while the first electrode units and the second electrode units are electrically independent respectively and perform the touch sensing function. In a second touch mode, the second electrode structure performs the touch sensing function.

Description

technical field [0001] The present invention relates to an electronic device, in particular to a touch panel and a touch display device. Background technique [0002] In recent years, touch-sensitive electronic products have been favored by consumers due to their convenient operation and high intuition, and have gradually become a mainstream trend in the market. The touch sensing principles commonly used today can be roughly divided into resistive, capacitive, infrared induction, electromagnetic induction, and sound wave induction. It has better advantages in response time and service life, so the integrated electronic devices of capacitive touch panels and displays have been widely used. With more and more functions of the touch-sensitive electronic products, the operation mode that needs to touch the device is gradually unable to meet the user's operation requirements. Therefore, in recent years, the floating touch electronic products have been further developed to incre...
